PROBLEM TO BE SOLVED: To prevent digital noise from mixing in analog signals by operating an analog signal processing circuit and a digital signal processing circuit, by time sharing according to whether processing time or the S/N is given higher priority in an imaging apparatus, having an IC where both the analog signal processing circuit and the digital signal processing circuit are mounted. SOLUTION: In the imaging apparatus, having an analog/digital mixed LSI 100 where both the analog signal processing section 101 and the digital signal processing section 102 are mounted, a signal-photographing mode for photographing a single frame and a continuous photograph mode for continuously photographing a plurality of frames are switched and set by an operation switch 31. When the single-photograph mode is set, power supply to the analog signal processing section and the digital signal processing section is turned on or off alternately by a power switch 34 for time-sharing processing operation. When the continuous photograph mode is set, power supply to the analog signal processing section and the digital signal processing section is turned on constantly for performing simultaneous parallel processing operation. |
