PROBLEM TO BE SOLVED: To provide an integrated circuit which can verify a function of a signal processing circuit by using image data of various patterns from a dynamic image without connecting a signal source to an external unit. SOLUTION: The integrated circuit are integrally constituted for verifying the function of the signal processing circuit for processing real image data to be input from the external unit. Further, the circuit has an address generating means 1 for generating a two-dimensional address based on an input synchronous signal, a data output means 2 for generating test image data by using the generated address, a selector 3 for switching the real image data and test image data and outputting the data, and the signal processing circuit 4 for processing image data output from the selector.
