PROBLEM TO BE SOLVED: To prevent memory overflow or missing of data by setting an operation of an image information compression rate prediction means into an inhibit state depending on setting entry. SOLUTION: Outputs 133, 134 of an image processing section 11 are compressed by a compression circuit of a PMB 15 and stored in a DRAM. Then DRAM residual amount detection signals 189, 199 are given to a controller 123 of the image processing section 11. Furthermore, various image processing mode signals from an OCU 3 are given to the controller 123. Then a compression rate prediction circuit 160 predicts the compression rate of the image based on information obtained from the controller 123 via a bus 161 and a filter circuit output signal and provides an output to the controller 123. Depending on the setting of the OCU 3 at that time, a decoration information/magnification information table is referenced and whether or not the compression rate prediction is to be conducted is discriminated and the result is informed to the controller 123. |
