Same storm expedient which the same storm processes the plural lines of the picture signal which is input

摘要

PROBLEM TO BE SOLVED: To efficiently use a memory of a digital camera. SOLUTION: Pluralities of lines of image data of raster scanning sequence which are white-balance-processed and given to a delay line control section 8 are subject to simultaneous processing by using memories 9-12, the result is subject to Y/C separation processing and the result is block-processed at a raster block conversion control section by using memories 23-30. The image signal block-processed is compressed according to the JPEG format. When no compression is applied to the image signal, the delay lien control section B throws switches 31-35 to the position 1 and uses the memories 9-12 and 27-30 to conduct simultaneous processing.
