System and method for foveated compression of image frames in a system on a chip

An exemplary method for intelligent compression uses a foveated-compression approach. First, the location of a fixation point within an image frame is determined. Next, the image frame is sectored into two or more sectors such that one of the two or more sectors is designated as a fixation sector and the remaining sectors are designated as foveation sectors. A sector may be defined by one or more tiles within the image frame. The fixation sector includes the particular tile that contains the fixation point and is compressed according to a lossless compression algorithm. The foveation sectors are compressed according to lossy compression algorithms. As the locations of foveation sectors increase in angular distance from the location of the fixation sector, a compression factor may be increased.

There is provided an encoding apparatus. A data processing unit generates binary data by performing data processing, including binarization processing, with respect to image data that has been input from an image capturing unit. An arithmetic coding unit generates arithmetic code data by performing arithmetic coding of the binary data. A control unit performs control so as to record the arithmetic code data into a recording unit. When the image data is still image data generated during continuous shooting of still images, the control unit performs control so as to record the binary data into the recording unit without generating the arithmetic code data.
