Abstract
An image processing device comprising: a setting unit configured to set a replacement difference coefficient that is a difference between a replacement coefficient and a coefficient located at the beginning of a quantization matrix whose size is limited to not greater than a transmission size that is a maximum size allowed in transmission, the replacement coefficient being used to replace a coefficient located at the beginning of an up-converted quantization matrix which is obtained by up-converting the quantization matrix to the same size as a block size that is a unit of processing in which dequantization is performed; a quantization unit configured to quantize an image to generate quantized data; and a transmission unit configured to transmit encoded data obtained by encoding the quantized data generated by the quantization unit, replacement coefficient data obtained by encoding the replacement coefficient, and replacement difference coefficient data obtained by encoding the replacement difference coefficient set by the setting unit.
