<p>PROBLEM TO BE SOLVED: To realize a high picture processing with a small quantity of memory by sharing one memory with a signal processing means and a compression means of a transfer means and using a linked list for the management of picture data on the memory. SOLUTION: AF control, AE control and AWB control in a photographing preparation procedure are executed by evaluating CCD data in the video processing circuit of a DSP 6. Areas where CCD data are stored are the two one-direction linked lists generated on DRAM 10. A memory area for one CCD line is one linear memory block and it comprises a tag part and a data part. The reference destination of a next line is stored in the tag part. The linear memory area of the individual lines is managed by a memory manager and the respective lines are the small memory blocks and they can freely be arranged on DRAM 10. Thus, the memory can effectively be used. The linked lists are generated by the photographing preparation procedure.</p> |
