Than as shown in Figure 3, after using terminal to take, the displaying situation of the image obtaining on terminal desktop.Wherein, due in moment, in image there is movement in the upper limbs of animal, makes to have formed ghost image and fuzzy consequence in image, this part image construction treat to need modification region 302 by the retake to this part, to realize replacement.
Based on technique scheme and object, from relevant several aspects, in conjunction with concrete execution mode, the implementation procedure of scheme is described in detail below.
1, chosen area
Embodiment mono-
In order to reduce the amount of calculation of terminal, and the user's self that can more fit demand, obviously should select voluntarily and determine the position for the treatment of modification region 302 by user.
As shown in Figure 4, in a kind of situation, on the image that user can directly revise at needs, select, such as mark corresponding gesture track 304 on image, terminal is based on this gesture track 304, directly generate as shown in Figure 3 treat modification region 302.
Certainly, user can directly mark the gesture track 304 of formation closed figure as shown in Figure 4; Also can be by the screen border of terminal, such as marking an end points, be connected to respectively the right side of terminal and the line segment (not shown) of downside frame, the common region forming of this line segment, screen Right Border, screen downside frame, be as shown in Figure 3 treat modification region 302.
In another kind of situation, user is without the gesture track 304 marking as shown in Figure 4, but as shown in Figure 5, the figure of alternative area can be directly provided by terminal, as rectangle, triangle, circle etc., user selects after a figure, is dragged to the region of wishing correction, and can adjust the size of this figure, regional graphics 306 correspondences that finally obtain be as shown in Figure 3 treat modification region 302.
Embodiment bis-
Based on some detections or recognizer, terminal also can realize the automatic identification for the treatment of modification region 302 in image and obtain.
In a kind of situation, can be by means of border detection algorithm.When owing to causing shooting element in image to occur as the situation such as fuzzy as shake, rock etc., can there are some default features in the characteristic attribute on the border of this shooting element.Ratio as shown in Figure 6, for situations such as " fuzzy ", can cause taking the identified border of element broadens, the numerical value that is the border width 308 in Fig. 6 becomes large, such as being greater than, in image, other take the border width of element, or be greater than other portion boundary width of same shooting element, or be greater than default width threshold value, or be greater than predetermined threshold value etc. with same shooting element or other differences of taking the border width of elements.
Whether clearly judgment mode based on border width 308, be actually border one of judgment mode; And in fact, such as whether waiting continuously other different judgment modes in border, obviously also may be used to the shooting element in image whether to need to revise carry out automatic decision.
(not shown) in another kind of situation, except the judgment mode based on Boundary algorithm, other features that can also be based on reference object, realize the automatic decision of terminal.Such as by setting in advance each characteristic attribute pre-conditioned of taking element in image, and by judging whether the real-time conditions of corresponding characteristic attribute in present image meets that this is pre-conditioned, thereby determine whether and need to revise.
Particularly, such as the middle appearance situation of " nictation " of taking pictures for comparatively common, there is " nictation " in the personage in image in moment, causes taking on the image obtaining, and this personage is the state of " closing one's eyes ".Thereby, relate to determining " closing one's eyes " situation herein.
First, based on current " recognition of face " algorithm of maturation, determine " people's face " in image; Then, be based upon " eyes " default characteristic parameter, such as the position of the upper middle at " people's face ", each of left and right, be (only for illustrating) such as black, whether identification should there is the object that meets above-mentioned feature on " people's face ".If exist, explanation does not have image problem, if do not exist, may have the situation of " nictation ", and by terminal directly by this user " people's face " partly or this user's integral body, as shown in Figure 3 treat modification region 302.
2, determine object
Based on the above embodiments one, owing to being that user manually selects, can directly generate as shown in Figure 3 treat modification region 302; And when based on the above embodiments two, while automatically being judged by terminal, relate to the problem for the treatment of the concrete shooting element that comprises in modification region 302.
Such as for the image shown in Fig. 3, suppose that the upper limbs of the animal in this image occurs fuzzy, again during photographic images, can only take fuzzy upper limbs part occurs, also can all again take the integral body of this animal.
As shown in Figure 7, take element 310A is the integral body that comprises the animal shown in Fig. 3 to ratio, and take element 310B, is only the upper limbs of the animal shown in Fig. 3.By again obtaining, take element 310B, make to have reduced as far as possible the correction to the original image shown in Fig. 3; And take element 310A by again obtaining, make, when fuzzy animal upper limbs occurring other parts are impacted, can reduce this impact as far as possible, and contribute to the total tune of the animal that assurance is taken.
3, take prompting
As shown in Figure 8, when determining, user need to re-start while taking, terminal can be by treating in the original shooting element 312(Fig. 8 in modification region 302 only for signal shown in Fig. 3, may be displayed on screen, can not show) yet, current shooting element 314 in the image receiving with present image transducer compares, to determine both, at acquisition parameters such as shooting angle, distance, light, white balance, focal lengths, whether mate, if there are differences, can provide certain prompting to user.In Fig. 8, by demonstrate information 316 on terminal interface, prompting user moves to corresponding direction, so that current shooting element 314 matches with original shooting element 312.
Certainly, concrete prompting mode has a lot, such as can also demonstrate original shooting element 312 and current shooting element 314 in terminal simultaneously, and when both overlap, gives user to point out accordingly, such as flashing, give a warning, vibration etc.
Meanwhile, for above-mentioned acquisition parameters, the part that can regulate voluntarily for terminal, terminal can be carried out automatic adjusting as much as possible, to reduce user's manual operation section, reduces the complexity of operation.
Finally, consistent or match in the situation that at acquisition parameters, or in the situation that user considers appropriate, carry out again and take, and automatically from the image of again taking, intercepted corresponding to the region of improving for the treatment of modification region 302 shown in Fig. 3 by terminal, use this to improve region replacement and treat modification region 302, and using the image obtaining as the image that finally completes processing.
More than be described with reference to the accompanying drawings technical scheme of the present invention, the present invention proposes a kind of image processing apparatus and a kind of image processing method, can part undesirable in image be replaced by the mode of retake, thereby obtain meeting the image of user's request.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
