Patent ID: 7038719

Claim:
An image sensing apparatus which converts optical information of an object into digital information and records the digital information in a primary storage as a compressed image file, comprising: a controller which controls start of photographing operation of a photographed image and start of recording operation of the photographed image; a front-end processing device which performs correction processing for image sensing data obtained by the photographing operation; a digital signal processing device which performs image processing and compression processing for the image sensing data corrected by said front-end processing device; a temporary storage device which stores the image sensing data processed by said digital signal processing device; and a primary storage device which records the image sensing data stored in said temporary storage device as a compressed image file, said front-end processing device comprising: an image sensing data storage device which temporarily stores the image sensing data obtained by the photographing operation; a storage controller which controls said image sensing data storage device; and a correction device which performs correction processing for the image sensing data supplied from said image sensing data storage device, said digital signal processing device comprising: a plurality of data accumulation devices; and a stop request device which outputs a wait request to said front-end processing device before any overflow occurs in all or at least one of said plurality of data accumulation devices, wherein said front-end processing device starts readout of image sensing data from said image sensing data storage device after recording operation of the image sensing data is started in accordance with instructions from said controller and temporarily stops transfer output of corrected image sensing data to said digital signal processing device if a wait request from said stop request device is detected.
