Abstract:
1. A camera control device integrated into an electronic equipment, comprising: an input circuit connected to an internal bus inside said camera control device and configured to input an image signal output from an image pickup sensor; a memory device connected directly only to the internal bus inside said camera control device and configured to store said image signal output from said image pickup sensor; a slave access controller provided entirely inside said camera control device and connected to said internal bus and directly to an external bus provided outside said camera control device; a serial interface connected to the internal bus inside said camera control device and to a second serial interface that is inside a processing unit including a CPU and that is connected to a second internal bus, physically distinct from the external bus, inside the processing unit, the serial interface configured to transfer a startup program for the camera control device from the processing unit, wherein the CPU is provided outside said camera control device, performs a general control of said electronic equipment and reads out said image signal stored as a compressed image in said memory device by sending a read instruction to the slave access controller which uses a predetermined circuit unit to transfer the compressed image from the memory device to the slave access controller which transfers the compressed image to the CPU through said external bus, and wherein said memory device is not directly controlled by the CPU.
