The various storage mediums such as memory, read-only storage, flash memory or DVD or USB flash disk, it is chosen as non-moment storage medium.
A specific example is provided below based on above-mentioned any embodiment：
In this example, when being shot using four-in-one camera, the figure of 4,000,000 pixels may be obtained
Picture.The image of 4,000,000 pixel substantially comprises 16,000,000 pixels, but due to the merging treatment of 4 pixels, if directly exporting
The image file of generation is gathered, is only capable of exporting the image of 4,000,000 pixels.The remosiac processing may be based on software calculation
The pixel rearrangement processing of method.For example, the pixel value that will be sorted according to pseudo- Bel's module (pseudo Bayer pattern)
The Bayer pattern (Bayer pattern) of standard is converted to, pixel is completed and resets.In specific implementation, at the remosiac
Reason may also include：Some picture quality liftings handle, for example, perform bad pixel correct (Bad Pixel Correction,
BPC), the bad pixel is corrected and may include：Removal of noise point etc..
In fig. 8, a grid can represent a pixel；The grid of identical filling before remosiac processing is carried out,
Same pixel available for the first image provides pixel-parameters, for example, brightness value.The grid of difference filling is at remosiac
Before reason, pixel-parameters are provided available for different pixels in the first image.
After remosiac processing is completed, the grid of identical filling is broken up, and is provided equivalent to for same pixel
The pixel value of pixel-parameters is broken up, and is rearranged.
Fig. 8 show the arrangement change schematic diagram of the pixel value after remosiac processing.Obvious remosiac before processings
Pixel storage format (i.e. pixel arrangement) afterwards is different.
If necessary to shoot the image of 16,000,000 pixels, then terminal needs the preview image by camera shooting to enter
Row remosiac processing, i.e., rearranged pixel, then obtain target image.
The remosiac processing may include：It will can only export the pixel of 16,000,000 pixels of the image of 4,000,000 pixels
Value, carry out rearrangement processing of the pixel value such as Coordinate Conversion and/or coordinate mapping in image file.
Under the application scenarios, if necessary to carry out Digital Zoom, after prior art can be to carrying out remosiac processing
The intermediate region of target image carries out Digital Zoom processing, i.e., first carries out remosiac and carry out Digital Zoom again.In this programme,
Terminal chooses the intermediate region (region is related to zoom size) for the image that four-in-one camera is shot according to the size of zoom,
Then Digital Zoom processing is carried out to the intermediate region, then remosiac processing is carried out to the region after Digital Zoom processing,
I.e., it has no all images are carried out with remosiac processing, remosiac processing only is carried out to the region after Digital Zoom,
So as to improve processing speed.
