Abstract

See full text

An image processing circuit includes a front stage signal processing circuit that performs processing of input data and outputs the data and a rear stage signal processing circuit that performs processing which is to be performed on the data obtained after processing of the input data performed by the front stage signal processing circuit and outputs the data. The image processing circuit is configured to be switchable to one state of a first state that performs processing of the input data using the front stage signal processing circuit, subsequently performs processing of the data using the rear stage signal processing circuit, and outputs the data, a second state that performs processing of the input data using the front stage signal processing circuit and outputs the data, and a third state that performs processing of the input data using the rear stage signal processing circuit and outputs the data.
