Abstract:
1. An image pickup apparatus, comprising: an image pickup device configured to generate image signals of picked up images; a converting unit configured to convert the image signals generated by the image pickup device to digital image signals; a memory configured to store the image signals obtained by the converting unit; and a memory control unit configured to control writing the image signals in the memory and reading each of the image signals from the memory, wherein the memory control unit assigns bands of the memory in order to simultaneously perform writing image signals in the memory and reading the image signals from the memory for displaying the picked up images or reading the image signals from the memory for recording the picked up images at different frame rates, the memory control unit is configured to sequentially store the picked up images in the memory by cyclically replacing an oldest image of the picked up images with a newest image of the picked up images, and a frame rate used to write the image signals in the memory is higher than a frame rate used to read the image signals from the memory.
