Abstract:
1. An electronic camera, comprising: an image pickup part for picking up an image of an object and generating image data; a microprocessor for controlling a system; a digital signal processor for performing a software signal processing on the image data; and a multi-port memory having a first port and a second port through which data can be independently accessed, wherein: the microprocessor writes the image data generated by the image pickup part to the multi-port memory through the first port; the digital signal processor reads the image data from the second port of the multi-port memory to perform 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, from the first port of the multi-port memory, the image data on which the software signal processing has been performed, and records the read image data on a recording medium for storing data, and in accordance with a progress in the software signal processing of the digital signal processor, the microprocessor controls data access to the multi-port memory so as to shorten a waiting time for the software signal processing.
