US Patent 7280136 Electronic camera and control integrated circuit for electronic camera

An electronic camera of the present invention comprises an image pickup part, a microprocessor, and a multi-port memory that has a first port and a second port through which data can be independently accessed. The microprocessor writes the image data to the multi-port memory through the first port. The digital signal processor reads the image data from the multi-port memory through the second port, performs the software signal processing on the image data, and writes the processed data to the multi-port memory through the second port. The microprocessor reads the image data on which the software signal processing has been performed from the multi-port memory through the first port and records the read image data from the multi-port memory on a recording medium that stores data.
