Abstract

An image processing apparatus has a buffer storage section for temporarily storing image data supplied from a system bus; an image processing section for receiving the data read out of the buffer storage section for performing image processing on the received data; a storage section for temporarily storing output data of the image processing section and transferring the output data to the system bus; a gate section for releasing connection between the system bus and the buffer storage section; and a control section for controlling the respective sections so that input/output of data with respect to the image processing section and input/output of data with respect to the system bus are performed in parallel. Accordingly, the transfer on the bus, and the internal transfer from the buffer to the image processing apparatus are operated separately for each other, so that the image processing apparatus can be operated at a high speed.
