    •  DETAILED DESCRIPTION OF THE EMBODIMENTS
  • Reference will now be made in detail to the present embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.
  • FIG. 1 is a diagram of a three-dimensional video system using a video processing apparatus 110 according to an embodiment of the present invention, and FIGS. 2A and 2B are diagrams of a left eye image and a right eye image displayed respectively on shutter glasses 130 shown in FIG. 1. The three-dimensional video system will be described in more detail with reference to FIGS. 1, 2A, and 2B. Referring to FIG. 1, the three-dimensional video system includes a video processing apparatus 110 including an infrared ray (IR) transmission unit 120 and shutter glasses 130 including an IR receiving unit 140. As shown, the video processing apparatus 110 includes a display unit and a video decoder. However, it is understood that the video decoder can be a separate set top box and/or reproducing apparatus and connected to the display unit.
  • Since the human left eye and right eye are separated from each other in a transverse direction, two-dimensional images seen from the left eye and the right eye are different from each other. The video processing apparatus 110 alternately outputs left eye images and right eye images that are not the same as each other onto a screen using the above principle. The human eye recognizes images as continuous video when the images are seen at a frame rate of 60 Hz or greater. Three-dimensional video is generated by combining images input through the left eye and right eye. Thus, in order for the human eye to recognize the three-dimensional images as continuous video without stopping, the video processing apparatus 110 outputs the images at a frame rate of at least 120 Hz. For example, when the video processing apparatus 110 outputs left eye images and right eye images alternately every 1/120 second, the brain of the viewer combines the different two-dimensional images to generate realistic three-dimensional images having perspective and reality.
  • When the viewer views the images outputted from the video processing apparatus 110 without any special equipment, the left eye image and the right eye image overlap with each other. To prevent the left eye image and the right eye image from overlapping, the viewer wears the shutter glasses 130. The shutter glasses 130 opens a left lens and closes a right lens, and closes the left lens and opens the right lens alternately in synchronization with the left and right eye images output by the video processing apparatus 110. The IR transmission unit 120 included in the video processing apparatus 110 transmits infrared ray signals to the shutter glasses 130 for the synchronization. The IR receiving unit 140 included in the shutter glasses 130 senses the infrared ray signals transmitted from the IR transmission unit 120, such that the shutter glasses 130 operates in synchronization with the video processing apparatus 110. While described as being infrared, it is understood that the communication between the transmission unit 120 and the glasses 130 can be using other light, radio, or energy frequencies, or can also be done using wired communications.
  • As described above, the shutter glasses 130 alternately blocks the left eye images and right eye images. However, as a result, the images irradiated to the eyes of the viewer through the shutter glasses 130 are darker than the images that are continuously input into the eyes of the viewer without blocking. In addition, since the shutter glasses 130 are dark, the images irradiated to the eyes of the viewer through the shutter glasses 130 are darker than the images output from the video processing apparatus 110. To prevent this, the video processing apparatus 110 adjusts the brightness of the images before outputting the three-dimensional video images onto the screen.
  • When the video processing apparatus 110 outputs a left eye image, the shutter glasses 130 opens the left lens and closes the right lens so that the image is irradiated to the eye of the viewer through the left lens. FIG. 2A shows that the shutter glasses 130 opens the left lens 130L and closes the right lens 130R. When the video processing apparatus 110 outputs a right eye image, the shutter glasses 130 opens the right lens 130R and closes the left lens 130L to block the image from being transmitted through the left lens. FIG. 2B shows that the shutter glasses 130 opens the right lens 130R and closes the left lens 130L.
  • Since the shutter glasses 130 alternately opens the left lens 130L and the right lens 130R, the left eye and the right eye of the viewer respectively view left eye images and right eye images every 1/120 second. In the shown embodiment, since the video processing apparatus 110 adjusts the brightness of the images before outputting the images in order to compensate for the reduction of brightness while the images pass through the shutter glasses 130, the images irradiated to the eyes of the viewer through the shutter glasses 130 are brighter than the original images, the brightness of which is not adjusted.
  • FIG. 3A is a block diagram of a video processing apparatus 300 according to an embodiment of the present invention. Referring to FIG. 3A, the video processing apparatus 300 includes a video data decoder 310, a brightness adjuster 320, a three-dimensional image converter 330, and an output unit 340. While not required, each of the units 310, 320, 330, and 340 can be one or more processors or processing elements on one or more chips or integrated circuits.
  • In a case where video data is recorded on a disk (such as a DVD, Blu-ray disc, etc.), when the disk is loaded into the video processing apparatus 300, the video data decoder 310 reads the video data from the loaded disk and decodes the read video data. While not required, the image processing apparatus 300 can include a drive to read the disc directly, or can be connected to a separate drive. Moreover, while not required in all embodiments, the video processing apparatus 300 may further include a communication unit (not shown) to communicate with an external server or an external terminal through a communication network and/or any wired/wireless connection (such as universal serial bus, infrared, Bluetooth, etc.). In this case, the video processing apparatus 300 downloads the video data from the external server or the external terminal onto a local storage device (not shown) through the communication unit, and then reads the video data stored in the local storage device and decodes the read video data. However, it is understood that aspects of the present invention are not limited to storing the video data in the local storage. For example, in other aspects, the video processing apparatus 300 may decode the video data transmitted from the external server or the external terminal through the communication unit by using a real-time streaming method. Furthermore, the video processing apparatus 300 may read the video data from any external storage device (such as a flash memory). The video data can be movies, television shows, video games, software interfaces, etc.
  • In the decoding of the video data, the video data decoder 310 extracts brightness components (or luminance components) Y and chrominance components Cr and Cb from pixels in image frames. The brightness adjuster 320 adjusts a brightness of the image frames using the brightness components Y extracted by the video data decoder 310. The brightness adjuster 320 adjusts the brightness of the image frames by controlling a brightness distribution in a frequency distribution table regarding distribution of luminance components. The frequency distribution table with respect to the brightness components is a histogram showing the brightness on a variance side of a horizontal axis, and the number of pixels in each brightness level on a frequency side of a vertical axis. The brightness is divided into 256 grades from 0 to 255, and the number of pixels corresponding to each level of brightness is denoted as the frequency. Embodiments in which the brightness adjuster 320 adjusts the brightness of the image frame by adjusting the brightness distribution of the frequency distribution table will be described in detail with reference to FIGS. 4A through 6B.
  • The video data input into the video data decoder 310 may be two-dimensional video data or three-dimensional video data. When the video data input into the video data decoder 310 is three-dimensional video data, the brightness adjuster 320 adjusts the brightness of the three-dimensional video data and transmits the brightness-adjusted three-dimensional video data to the output unit 340. When the video data input into the video data decoder 310 is two-dimensional video data, the brightness adjuster 320 adjusts the brightness of the two-dimensional video data and transmits the brightness-adjusted two-dimensional video data to the three-dimensional video converter 330. While shown as having both, it is understood that the apparatus 200 need not have both the capability of converting two dimensional video data to three dimensional video data as well as receiving three-dimensional data as shown.
  • The three-dimensional video converter 330 generates three-dimensional video data by providing depth to the two-dimensional video data. In this regard, the three-dimensional video converter 330 divides an image frame in the two-dimensional video data into blocks of predetermined sizes, and selects a block, which is the most similar to a predetermined block of the current frame, among blocks of a previous frame. Then, the three-dimensional video converter 330 calculates a motion vector for each of the divided blocks in the current frame, and generates a new frame by combining the selected blocks. However, aspects of the present invention are not limited to the above example. For example, in other aspects, the three-dimensional video converter 330 may generate a depth map using composition information of the image frames and generate a new frame in order to provide depth to the two-dimensional video.
  • The three-dimensional video converter 330 determines one of the new image frame and the current image frame as the left eye image and the other of the new image frame and the current image frame as the right eye image. Alternatively, the three-dimensional video converter 330 may generate a new left eye image and/or a new right eye image using the new image frame and the current image frame. The three-dimensional video converter 330 generates a three-dimensional format image frame, which includes both the left eye image and the right eye image in a frame, and transmits the generated three-dimensional format image frame to the output unit 340. The output unit 230 outputs the left and right eye images, which are included in the brightness-compensated frame, alternately at least every 1/120 second.
  • FIG. 3B is a block diagram of a video processing apparatus 350 according to another embodiment of the present invention. Referring to FIG. 3B, the video processing apparatus 350 includes a video data decoder 360, a three-dimensional video converter 370, a brightness adjuster 380, and an output unit 390. While not required, each of the units 350, 360, 370, 380, and 390 can be one or more processors or processing elements on one or more chips or integrated circuits. The brightness adjusters 320 and 380 of the video processing apparatuses 300 and 350 of FIGS. 3A and 3B, respectively, are located in different positions. Referring to FIG. 3B, when the input video is two-dimensional video, the video data decoder 360 decodes the input video and transmits the decoded video to the three-dimensional video converter 370. When the input video is three-dimensional video, the video data decoder 360 decodes the input video and transmits the decoded video to the brightness adjuster 380. The three-dimensional video converter 370 converts the received two-dimensional video to three-dimensional video, and transmits the converted video to the brightness adjuster 380. The brightness adjuster 380 adjusts brightness of the image frames in the three-dimensional video received from the video data decoder 360 or the three-dimensional video converter 370. The output unit 390 then outputs the brightness-adjusted three-dimensional video. As described above, both of the video processing apparatuses 300 and 350 illustrated in FIGS. 3A and 3B adjust the brightness of the video before outputting the three-dimensional video onto the screen (not shown) through the output units 340 and 390.
  • FIGS. 4A through 6B are frequency distribution tables illustrating a brightness conversion using the brightness adjusters 320 and 380 of the video processing apparatuses 300 and 350 illustrated in FIGS. 3A and 3B. Specifically, FIGS. 4A and 4B are histograms illustrating a brightness conversion of an image frame by the brightness adjuster 320 or 380 according to an embodiment of the present invention. FIG. 4A is a histogram of the brightness before being adjusted by the brightness adjuster 320 or 380. Referring to FIG. 4A, the brightness level of a pixel that has the highest brightness from among the pixels in the current image frame is not higher than the grade 255. In FIG. 4A, a difference between the brightness level of the pixel having the highest brightness among the pixels in the current image frame and the grade 255 is denoted as (1). In this case, the brightness adjuster 320 or 380 may adjust the frequency distribution of the histogram so that the brightness level of the pixel having the highest brightness from among the pixels in the current image frame has the grade 255. That is, the brightness adjuster 320 or 380 adjusts the frequency distribution so that the brightness of all of the pixels can be brighter by as much as (1) or less. FIG. 4B is a histogram showing the brightness of the frame when the brightness levels of all of the pixels in the frame are increased by as much as (1) or (2) that is less than (1) but is greater than zero.
  • FIGS. 5A and 5B are histograms illustrating a brightness conversion of an image frame by the brightness adjuster 320 or 380 according to another embodiment of the present invention. FIG. 5A is a histogram of the brightness of the frame before being adjusted by the brightness adjuster 320 or 380. Referring to FIG. 5A, the brightness level of a pixel that has the highest brightness among the pixels in the current image frame is not higher than the grade 255 (as in FIG. 4A). When it is assumed that the brightness level of the pixel having the highest brightness from among the pixels of the current image frame is M and the brightness level of the pixel having the lowest brightness is N in FIG. 5A, the brightness adjuster 320 or 380 adjusts the frequency distribution of the histogram so that the brightness level of the pixel having the lowest brightness is N and the brightness level of the pixel having the highest brightness is grade 255, as shown in FIG. 5B. The section between the lowest brightness level and the highest brightness level is divided into grades of constant sizes. Before adjusting the frequency distribution, the section between the lowest brightness level of the frame and the highest brightness level of the frame is divided into the number of grades that is obtained by subtracting N from M. However, after adjusting the frequency distribution, the section between the lowest brightness level of the frame and the highest brightness level of the frame is divided into the number of grades obtained by subtracting N from 255. In this case, pixels having brightness levels between the grade 255 and M are generated, and the brightness of the frame can be increased. While shown as N=0, it is understood that N can be greater than 0 in other circumstances.
  • FIGS. 6A and 6B are histograms illustrating the brightness conversion of the image frame by the brightness adjuster 320 or 380 according to the other embodiment of the present invention. FIG. 6A is a histogram of the brightness of the frame before being adjusted by the brightness adjuster 320 or 380. Referring to FIG. 6A, when it is assumed that the brightness level of the pixel having the highest brightness among the pixels of the current image frame is M and the brightness level of the pixel having the lowest brightness is N, the brightness adjuster 320 or 380 adjusts the brightness distribution in the histogram using a predetermined reference grade K that is greater than N and less than M. The brightness adjuster 320 or 380 may adjust the grades so that the reference grade K can be moved in the left direction of the histogram (i.e., towards N).
  • In FIG. 6A, the section between the grade N and the grade K is denoted as (3) and the section between the grade K and the grade M is denoted as (4). Before adjusting the brightness, the distances of grades in section (3) and section (4) are the same as each other. However, when the brightness adjuster 320 or 380 moves the grade K toward the grade 0 as shown in FIG. 6B, section (3) is reduced and section (4) is increased. This means that a distance between the grades in section (4) is greater than a distance between the grades in section (3). That is, since the brightness of the dark section is finely defined, the brightness of the frame is improved.
  • FIG. 7 is a flowchart illustrating a video processing method using the video processing apparatus 300 of FIG. 3A, according to an embodiment of the present invention. Referring to FIG. 7, the video data decoder 310 decodes input video data in operation 710, and the brightness adjuster 320 adjusts the brightness of the decoded video data in operation 720. The video processing apparatus 300 determines whether the brightness-adjusted video data is two-dimensional video data or three-dimensional video data in operation 730. When the video data is determined to be two-dimensional video data (operation 730), the three-dimensional video converter 370 converts the two-dimensional video data into three-dimensional video data in operation 740, and the output unit 340 outputs the converted video data in operation 750. When the video data is determined to be three-dimensional video data (operation 730), the output unit 340 outputs the three-dimensional video data in operation 750 without performing the conversion operation (operation 740).
  • As described above, according to aspects of the present invention, the brightness of video images is adjusted before outputting three-dimensional video. Thus, problems caused by dark video images when a viewer watches three-dimensional video using shutter glasses can be overcome.
  • While not restricted thereto, aspects of the present invention can also be embodied as computer-readable code on a computer-readable recording medium. The computer-readable recording medium is any data storage device that can store data that can be thereafter read by a computer system. Examples of the computer-readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, and optical data storage devices. The computer-readable recording medium can also be distributed over network-coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion. Aspects of the present invention may also be realized as a data signal embodied in a carrier wave and comprising a program readable by a computer and transmittable over the Internet. Moreover, while not required in all aspects, one or more units of the video processing apparatus 300 or 350 can include a processor or microprocessor executing a computer program stored in a computer-readable medium, such as a local storage.
  • Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
