PURPOSE: To display a subject onto a monitor at a high speed by constituting the processor capable of storing image data in a main memory and a display memory for monitor display in parallel. CONSTITUTION: A terminal A of a changeover circuit 7 is connected to terminals B, C and a terminal F of a changeover circuit 8 is connected to a terminal G in the scanning operation under the control of a CPU 3 respectively. Image data outputted from a camera input section 1 via a bus are stored in a main memory 2 via the terminal A, B of the circuit 7 and outputted to the terminal E of the circuit 8 via the terminal C and a thinning circuit 9. Since the terminals F, G of the circuit 8 are connected, resulting that image data from the input section 1 are subjected to thinning processing by the circuit 9 and the result is stored in a display memory 4 and then read as they are. Thus, an entire object image subjected to thinning is displayed on a monitor 5 almost at the same time for image reception. |
