Image processing facility with continuous shooting function, adopt continuous photo processing unit of the present invention after, can improve the compression ratio of continuous photo equally.
Below to the processing method of continuous photo of the present invention, describe.
Start continuous shooting function the user, carry out continuous shooting after, the processing of continuous photo be may further comprise the steps:
Step 201 after all the pixel data storages with each continuous photo, is divided into the experimental process rectangle according to identical division methods;
Step 202: store each sub-rectangular pixels data again according to the sub-rectangle of dividing;
Below be example with Fig. 3, illustrate how to cut apart and store each sub-rectangular pixels data.
Suppose that Fig. 3 is continuous photo wherein, width width=10, with the top left corner apex is the origin of coordinates, which row y represents, value is 0-6, which row x represents, value is 0-9, according to x, y coordinate setting is to any one point of image, and the pixel data of a for example whole photo is stored in the middle of the array of char type, be linear array, be stored as: 12,345,678,901,234,567,890,123,456,789,012,345,678,901,234,567,890,123,456 7890, according to image[y*width+x] and just can calculate coordinate x, (width is the width of whole rectangle photo to the pixel value of y, be 10), if this photo is divided into 6 sub-rectangles, when storing first sub-rectangular area, get two line data, following the example of of it is exactly: image[0*width+0] get 5 pixels for starting point, and then image[1*width+0] get 5 pixels for starting point, it is exactly the pixel data of first sub-rectangle that the data of taking out for this twice link together, and is stored as: 1234512345.
Step 203: divide smaller group, each pixel data that compares the corresponding sub-rectangle of group is compared, obtain repeat region information and difference section domain information;
Is one group with all continuous photos with at least two, be divided into several relatively groups, relatively each compares in the group simultaneously or successively, whether the pixel data of the correspondence of corresponding sub-rectangle is identical, if the pixel data of corresponding sub-rectangle is all identical, then identifying this sub-rectangle is repeat region, otherwise is the difference zone.
If find certain to certain of the sub-rectangle of correspondence to respective pixel data difference, then indicating the sub-rectangle of this correspondence is the difference zone, end is to the comparison of the sub-rectangle of this correspondence, if certain is all identical to all respective pixel data of the sub-rectangle of correspondence, then indicating the sub-rectangle of this correspondence is repeat region, continues the comparison of the sub-rectangle data pixel of a pair of correspondence down; Finish the comparison that all compare group and sub-rectangle thereof, obtain each repeat region that compares group and compare the difference zone of each photo in the group with each,
The difference comparative result that comprises difference section domain information and repeat region information can be stored in the file system in working area.
Step 204: each repeat region that compares group is carried out code storage;
For a comparison group, repeat region only need be encoded once, and repeat region is big more, and compression ratio is just high more.
Step 205: each continuous photo that compares in the group is handled, promptly reduced repeat region, and fill simple and easy data, as 0 according to comparative result;
According to comparative result, the position in repeat region and difference zone is known, at this moment (a kind of standard C language is to the operation of internal memory to adopt the method for memoryset, storing view data in this internal memory) pixel data of extra-regional repeat region is set at 0, delivering to encoder after the repeat region of former photo is inserted 0 compresses.
Step 206: the photo after handling is carried out code storage, and record respectively compares the related information of group's repeat region and former photo simultaneously, to merge reduction according to this related information.
Related information is stored in the picture-storage database, comprises the filename of handling the back photo, the repeat region numbering related with this document name, the positional information (or the opposed area positional information in repeat region and difference zone) of repeat region in former photo etc.
May store a plurality of this processing modes in the image processing facility, and filename is independently not bear the same name, associates, when Showing Picture, just know to take out which repeat region together to show with the repeat region of file and numbering.
Above continuous photo storage means, can be realized by the high compression memory function that digital image processing equipment carries out after the continuous shooting: promptly the user selects first continuous shooting function to carry out continuous shooting; After continuous shooting was finished, the user selected hold function and selects the high compression storage to preserve captured photo.
When the user browses the continuous photo of preservation, start the photo function of browse, behind certain continuous photo that selection will be browsed, the continuous photo processing unit is carried out following steps:
Step 401: the association number of the filename of the photo of selecting to browse according to the user (photo herein is a photo after handling, that have only the difference zone), find the code storage file of related repeat region;
Step 402: repeat region and processing back photo are decoded;
The process of decoding is the process that the picture in repeat region and difference zone is become again pixel data.
Step 403: according to the positional information of repeat region in the related information, merge decoded processing back photo (difference zone) and repeat region, obtain the integral photograph pixel data, to show integral photograph.
The pixel data of decoded picture is stored in the middle of the array of char type, be linear array, we can be according to x, y coordinate setting is to any one point of image, image[y*width+x for example] be exactly coordinate x, the pixel value of y, the repeat region numbering is searched coordinate information in the picture-storage database, according to the x that finds, the y coordinate information, method (this is the C language data processing function of standard, is used for carrying out data and merges) with memcpy copies the pixel data of repeat region in the pixel data of original image to.
Shape after the shape of continuous photo and the division, the ability that depends on encoder, just present technology is to be divided into the rectangle subregion, relatively be easy to realize, but along with the development of coding techniques, the shape of subregion maybe can change, in some sense, this subregion can refine to row or column or single pixel, finish diversity ratio after, as long as relatively the repeat region of group is once encoded and write down enough related informations, can realize the object of the invention.
Diversity ratio after, former photo is reduced filling according to the difference comparative result, need the related information of record less relatively on the one hand, and after reducing filling, concerning the difference zone of former photo, no matter whether the difference zone is continuous, as long as code storage, when browsing, to compare former photo size size constant because of handling the back photo, also handles than the merging that is easier to realize and handle the back photo after the repeat region decoding.
Based on inventive concept, also can keep (comparing in the group) photo and not reduce the filling processing, write down itself and the coordinate position of repeat region in photo of (relatively group in) other photos, which no matter is browsed open photo, all need earlier the photo of handling to be decoded, with will be wherein the pixel data of repeat region copy the appropriate location of the pixel data of the photo after the processing that will browse to, with the photo that reduction will be browsed, this method is more complicated comparatively speaking.
Also have a kind of method to be, each photo is not all reduced filling, and just according to the difference comparative result, distinguish code storage difference zone and (comparison group) repeat region, in order to reduce photo, need the related information of record more relatively, comprise former photo size, difference zone and the repeat region positional information (such as the order information of boundary coordinate position in former photo coordinate system or implicit position relation) in former photo, and/or the opposed area position of difference zone and repeat region.
Must, the related information of record must be the information summation that enough is used for merging repeat region and difference zone reduction photo.
No matter whether reduce filling, because of respectively code storage being carried out in the difference zone of repeat region and participation each continuous photo relatively, be less than participation number of pictures relatively as long as guarantee the coding number of times of repeat region, just can improve the compression ratio of continuous photo, optimum treatment mode is that repeat region is only encoded once certainly.
