Electronic camera apparatus equipped with preview image preparation function

摘要

In a recording mode, when an image pickup is indicated by the depression of a shutter key (5), at first, a preview image is generated by thinning out the picked-up image. Then, the preview image is compressed by using a fixed compression parameter by a JPEG circuit (42). The image is recorded in a preview image area (40a) of a flash memory (40), and at the same time, a compression factor (compression size) for the compression of the preview image is stored temporarily. Next, a main image is compressed by using a compression parameter determined based on the stored compression factor in the JPEG circuit (42). This main image is recorded in a main image area (40b) of the flash memory (40). <IMAGE>
