Semiconductor integrated circuit, imaging system, and signal conversion method

摘要

An adjacent color difference data generator calculates a differential between adjacent data in a data row having different color information per pixel of the digital signal to thereby generate a first color difference data having a first code format. A code converter converts the first color difference data into a second color difference data having a second code format. The second code format is a code format where only a small number of bits change before and after the code conversion from the first code format. The number of changing bits in the switching between codes when, for example, an image monochromatic but having gradation change is imaged to reduce any noise generated when digital image data is outputted.
