Abstract
An image data storage/processing apparatus is provided, which is particularly applicable to an electronic still camera, for example. The image data storage apparatus uses a dynamic RAM as a frame memory for temporarily storing image data representative of a field of an image to be recorded. The frame memory includes at least first and second memories. In the apparatus, there is provided a control so that the image data corresponding to the adjacent two pixel lines on the field are continuously read out in such a manner that they are simultaneously read out from the first and second memories, and the image data corresponding to one of the two pixel lines are read out with delay by the time required for reading out of the image data corresponding to the other pixel line. The image signal processing apparatus is capable of performing processing for writing in and reading out of various types of image data with a single memory.
