Abstract
An image processing apparatus which allows a plurality of access circuits to perform access operations simultaneously including a first access circuit for writing a video signal in digital form, obtained by A/D conversion, into an image memory, a plurality of process memories for storing necessary data, taken out from the video signals stored in the image memory, a plurality of second access circuits for accessing the image memory and the process memories, and performing specified data processing to obtain necessary data from the image memory, and a third access circuit having the same functions as the second access circuits and a function to control the operation of the first and second access circuits. Access switchover circuits are provided for each of the image memory and process memories, for switching over access to the memories to either the first, second or third access circuits.
