PROBLEM TO BE SOLVED: To solve the problem that processing speed for recording data falls off in accordance with temperature rise of a disk recorder of a photographing device in the conventional photographing device.SOLUTION: Only one at lower temperature of ASICs 8a, 8b is operated in prescribed timing from observation results of temperature sensors 9a, 9b by a CPU 2. Thus, the processing speed does not fall off with intermittent processing performed in accordance with the temperature rise of the device like the conventional photographing device, and since one of the ASICs 8a, 8b at lower temperature continuously performs image processing, fall off of the processing speed by the temperature rise of the ASICs 8a, 8b is prevented. In addition, since the ASIC 8 at lower temperature is selected and operated, increase in loss of power consumption by heat generation to be generated by continuous operation of the ASIC 8 at higher temperature is reduced as much as possible, and generation of a failure of the ASICs 8a, 8b is prevented. |
