Abstract
The image transmission system, which transmits image data from a transmission side and performs image processing at a reception side, is provided with: an image transmission device that encodes an input image and outputs and a bitstream; an image reception device that receives and decodes the bitstream and performs image processing; a bit precision information generation unit that generates bit precision information for each region in the image; a quantization control unit that controls the quantization step width in a quantization process performed in the image transmission device in accordance with the bit precision information generated by the bit precision information generation unit; and an image processing unit that performs image processing using the decoded image that has been decoded by the image reception device. The bit precision information generation unit switches the method for generating bit precision information in accordance with the processing mode of the image processing unit.
