  • the embodiments of the invention use an ink jet printer type device. Of course many different devices could be used. However presently popular ink jet printing technologies are unlikely to be suitable.
  • thermal inkjet The most significant problem with thermal inkjet is power consumption. This is approximately 100 times that required for high speed, and stems from the energy-inefficient means of drop ejection. This involves the rapid boiling of water to produce a vapor bubble which expels the ink. Water has a very high heat capacity, and must be superheated in thermal inkjet applications. This leads to an efficiency of around 0.02%, from electricity input to drop momentum (and increased surface area) out.
  • piezoelectric inkjet The most significant problem with piezoelectric inkjet is size and cost. Piezoelectric crystals have a very small deflection at reasonable drive voltages, and therefore require a large area for each nozzle. Also, each piezoelectric actuator must be connected to its drive circuit on a separate substrate. This is not a significant problem at the current limit of around 300 nozzles per print head, but is a major impediment to the fabrication of pagewide print heads with 19,200 nozzles.

  • the print head is 100 mm long, with a width which depends upon the inkjet type.
  • the smallest print head designed is IJ38, which is 0.35 mm wide, giving a chip area of 35 square mm.
  • the print heads each contain 19,200 nozzles plus data and control circuitry.
  • Ink is supplied to the back of the print head by injection molded plastic ink channels.
  • the molding requires 50 micron features, which can be created using a lithographically micromachined insert in a standard injection molding tool.
  • Ink flows through holes etched through the wafer to the nozzle chambers fabricated on the front surface of the wafer.

    • FIELD OF THE INVENTION
  • The present invention relates to digital cameras and in particular, the onboard processing and printing of images captured by the camera.
    • BACKGROUND OF THE INVENTION
  • Recently, digital cameras have become increasingly popular. These cameras normally operate by means of imaging a desired image utilising a charge coupled device (CCD) array and storing the imaged scene on an electronic storage medium for later down loading onto a computer system for subsequent manipulation and printing out. Normally, when utilising a computer system to print out an image, sophisticated software may available to manipulate the image in accordance with requirements.
  • Unfortunately such systems require significant post processing of a captured image and normally present the image in an orientation to which it was taken, relying on the post processing process to perform any necessary or required modifications of the captured image. Further, much of the environmental information available when the picture was taken is lost.
    • SUMMARY OF THE INVENTION
  • It is an object of the present invention to provide for the utilisation of exposure information in an image specific manner.
  • Accordingly, the present invention provides a digital camera for sensing and storing an image, the camera comprising:
  • an image sensor with a charge coupled device (CCD) for capturing image data relating to a sensed image, and an auto exposure setting for adjusting the image data captured by the CCD in response to the lighting conditions at image capture; and,
  • an image processor for processing image data from the CCD and storing the processed data; wherein,
  • the image processor is adapted to use information from the auto exposure setting relating to the lighting conditions at image capture when processing the image data from the CCD.
  • Utilising the auto exposure setting to determine an advantageous re-mapping of colours within the image allows the processor to produce an amended image having colours within an image transformed to account of the auto exposure setting. The processing can comprise re-mapping image colours so they appear deeper and richer when the exposure setting indicates low light conditions and re-mapping image colours to be brighter and more saturated when the auto exposure setting indicates bright light conditions.
    • BRIEF DESCRIPTION OF DRAWINGS
  • Notwithstanding any other forms which may fall within the scope of the present invention, preferred forms of the invention will now be described, by way of example only, with reference to the accompanying drawings which:
  • FIG. 1 is a block diagram of a digital camera of the preferred embodiment;
  • FIG. 2 illustrates a form of print roll ready for purchase by a consumer;
  • FIG. 3 illustrates a perspective view, partly in section, of an alternative form of a print roll;
  • FIG. 4 is a left side exploded perspective view of the print roll of FIG. 3; and,
  • FIG. 5 is a right side exploded perspective view of a single print roll.
    •  DESCRIPTION OF PREFERRED AND OTHER EMBODIMENTS
  • The preferred embodiment is preferable implemented through suitable programming of a hand held camera device such as that described in the present applicant's application entitled “A Digital Image Printing Camera with Image Processing Capability”, the content of which is hereby specifically incorporated by cross reference and the details of which, and other related applications are set out in the tables below.
  • The aforementioned patent specification discloses a camera system, hereinafter known as an “Artcam” type camera, wherein sensed images can be directly printed out by an Artcam portable camera unit. Further, the aforementioned specification discloses means and methods for performing various manipulations on images captured by the camera sensing device leading to the production of various effects in any output image. The manipulations are disclosed to be highly flexible in nature and can be implemented through the insertion into the Artcam of cards having encoded thereon various instructions for the manipulation of images, the cards hereinafter being known as Artcards. The Artcam further has significant onboard processing power by an Artcam Central Processor unit (ACP) which is interconnected to a memory device for the storage of important data and images.
  • In the preferred embodiment, the Artcam has an auto exposure sensor for determining the light level associated with the captured image. This auto exposure sensor is utilised to process the image in accordance with the set light value so as to enhance portions of the image.
  • Preferably, the area image sensor includes a means for determining the light conditions when capturing an image. The area image sensor adjusts the dynamic range of values captured by the CCD in accordance with the detected level sensor. The captured image is transferred to the Artcam central processor and stored in the memory store. Intensity information, as determined by the area image sensor, is also forwarded top the ACP. This information is utilised by the Artcam central processor to manipulate the stored image to enhance certain effects.
  • Turning now to FIG. 1, Artcam 20 is illustrated in which auto exposure setting information 1 is utilised in conjunction with stored image 2 to process the image by utilising ACP 3. The processed image is returned to the memory store 2 for later printing out on printer 4 or printed directly.
  • A number of processing steps can be undertaken in accordance with the determined light conditions. Where the auto exposure setting 1 indicates that the image was taken in a low light condition, the image pixel colours are selectively re-mapped so as to make the image colours stronger, deeper and richer.
  • Where the auto exposure information indicates that highlight conditions were present when the image was taken, the image colours can be processed to make them brighter and more saturated. The re-colouring of the image can be undertaken by conversion of the image to a hue-saturation-value (HSV) format and an alteration of pixel values in accordance with requirements. The pixel values can then be output converted to the required output colour format of printing.
  • Of course, many different re-colouring techniques may be utilised. Preferably, the techniques are clearly illustrated on the pre-requisite Artcard inserted into the reader. Alternatively, the image processing algorithms can be automatically applied and hard-wired into the camera for utilization in certain conditions.
  • Alternatively, the Artcard inserted could have a number of manipulations applied to the image which are specific to the auto-exposure setting. For example, clip arts containing candles etc could be inserted in a dark image and large suns inserted in bright images.
  • Referring now to FIGS. 2 to 5, the Artcam prints the images onto media stored in a replaceable print roll 5. In some preferred embodiments, the operation of the camera device is such that when a series of images is printed on a first surface of the print roll, the corresponding backing surface has a ready made postcard which can be immediately dispatched at the nearest post office box within the jurisdiction. In this way, personalized postcards can be created.
  • It would be evident that when utilising the postcard system as illustrated FIG. 2 only predetermined image sizes are possible as the synchronization between the backing postcard portion and the front image must be maintained. This can be achieved by utilising the memory portions of the authentication chip stored within the print roll 5 to store details of the length of each postcard backing format sheet. This can be achieved by either having each postcard the same size or by storing each size within the print rolls on-board print chip memory.
  • In an alternative embodiment, there is provided a modified form of print roll which can be constructed mostly from injection moulded plastic pieces suitably snapped fitted together. The modified form of print roll has a high ink storage capacity in addition to a somewhat simplified construction. The print media onto which the image is to be printed is wrapped around a plastic sleeve former for simplified construction. The ink media reservoir has a series of air vents which are constructed so as to minimise the opportunities for the ink flow out of the air vents. Further, a rubber seal is provided for the ink outlet holes with the rubber seal being pierced on insertion of the print roll into a camera system. Further, the print roll includes a print media ejection slot and the ejection slot includes a surrounding moulded surface which provides and assists in the accurate positioning of the print media ejection slot relative to the printhead within the printing or camera system.
  • Turning to FIG. 3 there is illustrated a single point roll unit 5 in an assembled form with a partial cutaway showing internal portions of the print roll. FIG. 4 and FIG. 5 illustrate left and right side exploded perspective views respectively. The print roll 5 is constructed around the internal core portion 6 which contains an internal ink supply. Outside of the core portion 6 is provided a former 7 around which is wrapped a paper or film supply 8. Around the paper supply it is constructed two cover pieces 9, 10 which snap together around the print roll so as to form a covering unit as illustrated in FIG. 3. The bottom cover piece 10 includes a slot 11 through which the output of the print media 12 for interconnection with the camera system.
  • Two pinch rollers 13, 14 are provided to pinch the paper against a drive pinch roller 15 so they together provide for a decurling of the paper around the roller 15. The decurling acts to negate the strong curl that may be imparted to the paper from being stored in the form of print roll for an extended period of time. The rollers 13, 14 are provided to form a snap fit with end portions of the cover base portion 10 and the roller 15 which includes a cogged end 16 for driving, snap fits into the upper cover piece 9 so as to pinch the paper 12 firmly between.
  • The cover pieces 9, 10 includes an end protuberance or lip 17. The end lip 17 is provided for accurately alignment of the exit hole of the paper with a corresponding printing heat platen structure within the camera system. In this way, accurate alignment or positioning of the exiting paper relative to an adjacent printhead is provided for full guidance of the paper to the printhead.
  • It would be appreciated by a person skilled in the art that numerous variations and/or modifications may be made to the present invention as shown in the specific embodiment without departing from the spirit or scope of the invention as broadly described. The present embodiment is, therefore, to be considered in all respects to be illustrative and not restrictive.
  • The present invention is best utilized in the Artcam device, the details of which are set out in the following paragraphs.
    • Ink Jet Technologies
  • The embodiments of the invention use an ink jet printer type device. Of course many different devices could be used. However presently popular ink jet printing technologies are unlikely to be suitable.
  • The most significant problem with thermal inkjet is power consumption. This is approximately 100 times that required for high speed, and stems from the energy-inefficient means of drop ejection. This involves the rapid boiling of water to produce a vapor bubble which expels the ink. Water has a very high heat capacity, and must be superheated in thermal inkjet applications. This leads to an efficiency of around 0.02%, from electricity input to drop momentum (and increased surface area) out.
  • The most significant problem with piezoelectric inkjet is size and cost. Piezoelectric crystals have a very small deflection at reasonable drive voltages, and therefore require a large area for each nozzle. Also, each piezoelectric actuator must be connected to its drive circuit on a separate substrate. This is not a significant problem at the current limit of around 300 nozzles per print head, but is a major impediment to the fabrication of pagewide print heads with 19,200 nozzles.
  • Ideally, the inkjet technologies used meet the stringent requirements of in-camera digital color printing and other high quality, high speed, low cost printing applications. To meet the requirements of digital photography, new inkjet technologies have been created. The target features include:
  • low power (less than 10 Watts)
  • high resolution capability (1,600 dpi or more)
  • photographic quality output
  • low manufacturing cost
  • small size (pagewidth times minimum cross section)
  • high speed (<2 seconds per page).
  • All of these features can be met or exceeded by the inkjet systems described below with differing levels of difficulty. 45 different inkjet technologies have been developed by the Assignee to give a wide range of choices for high volume manufacture. These technologies form part of separate applications assigned to the present Assignee as set out in the table below.
  • The inkjet designs shown here are suitable for a wide range of digital printing systems, from battery powered one-time use digital cameras, through to desktop and network printers, and through to commercial printing systems
  • For ease of manufacture using standard process equipment, the print head is designed to be a monolithic 0.5 micron CMOS chip with MEMS post processing. For color photographic applications, the print head is 100 mm long, with a width which depends upon the inkjet type. The smallest print head designed is IJ38, which is 0.35 mm wide, giving a chip area of 35 square mm. The print heads each contain 19,200 nozzles plus data and control circuitry.
  • Ink is supplied to the back of the print head by injection molded plastic ink channels. The molding requires 50 micron features, which can be created using a lithographically micromachined insert in a standard injection molding tool. Ink flows through holes etched through the wafer to the nozzle chambers fabricated on the front surface of the wafer. The print head is connected to the camera circuitry by tape automated bonding.

    • Tables of Drop-on-Demand Inkjets
  • Eleven important characteristics of the fundamental operation of individual inkjet nozzles have been identified. These characteristics are largely orthogonal, and so can be elucidated as an eleven dimensional matrix. Most of the eleven axes of this matrix include entries developed by the present assignee.
  • The following tables form the axes of an eleven dimensional table of inkjet types.
  •
    Actuator mechanism (18 types)
    Basic operation mode (7 types)
    Auxiliary mechanism (8 types)
    Actuator amplification or modification method (17 types)
    Actuator motion (19 types)
    Nozzle refill method (4 types)
    Method of restricting back-flow through inlet (10 types)
    Nozzle clearing method (9 types)
    Nozzle plate construction (9 types)
    Drop ejection direction (5 types)
    Ink type (7 types)
  • The complete eleven dimensional table represented by these axes contains 36.9 billion possible configurations of inkjet nozzle. While not all of the possible combinations result in a viable inkjet technology, many million configurations are viable. It is clearly impractical to elucidate all of the possible configurations. Instead, certain inkjet types have been investigated in detail. These are designated IJ01 to IJ45 above.
  • Other inkjet configurations can readily be derived from these 45 examples by substituting alternative configurations along one or more of the 11 axes. Most of the IJ01 to IJ45 examples can be made into inkjet print heads with characteristics superior to any currently available inkjet technology.
  • Where there are prior art examples known to the inventor, one or more of these examples are listed in the examples column of the tables below. The IJ01 to IJ45 series are also listed in the examples column. In some cases, a printer may be listed more than once in a table, where it shares characteristics with more than one entry.
  • Suitable applications include: Home printers, Office network printers, Short run digital printers, Commercial print systems, Fabric printers, Pocket printers, Internet WWW printers, Video printers, Medical imaging, Wide format printers, Notebook PC printers, Fax machines, Industrial printing systems, Photocopiers, Photographic minilabs etc.
  • The information associated with the aforementioned 11 dimensional matrix are set out in the following tables.
