PROBLEM TO BE SOLVED: To solve nonconformities accompanying the increase in the image data amount, in an image signal processing apparatus. SOLUTION: The apparatus is equipped with an LSI 21 having a video signal processing unit which outputs video output data to a display device and having a ROM access control circuit 22 which holds the data to control the operation of the video signal processing unit; and a flash ROM 23 which is provided outside the LSI 21, holds the control data to be sent to the ROM access control circuit, and can control writing and reading of the data by the ROM access control circuit 22. The LSI 21 is provided with an input and output terminal 27c connected commonly to the flash ROM 23, so that the video output data is outputted to the display device through the input and output terminal 27c, and the data are transferred between the ROM access control circuit 22 and the flash ROM 23.
