Image signal processing circuit and semiconductor device

摘要

An image signal processing circuit is provided that can narrow the bus width of a bus that outputs data. The circuit is equipped with resistances R₁~R₅₁₁ that are serially connected between a first power supply potential V_T and a second power supply potential V_B, comparators C₁~C₅₁₁ having first inputs in which potentials V₁~V₅₁₁ on terminal sections of the resistances R₁~R₅₁₁ are input, respectively, and second inputs in which an analog image signal is input, and an encoder 42 that encodes output signals of the comparators C₁~C₅₁₁ into unsigned integer numbers of 9-bit width and outputs the same as digital image data.
