Abstract:
1. A digital camera being driven by a battery comprising: a judging circuit for determining a property of said battery; a memory having stored plural operation sequences for activating said digital camera, each operation sequence performing different power consumption of said battery and causing said digital camera to perform different operation; a selector for selecting one of said plural operation sequences in accordance with said property of battery decided by said judging circuit, for activating said digital camera based on said selected operation sequence; an imaging device for performing photoelectric conversion of incident light so as to output an original image signal; an image processing circuit for performing image processing to said image signal; a memory for storing a processed image signal that said image processing circuit processes said original image signal outputted from said imaging device upon taking a still image; a CPU for controlling said imaging device, said image processing circuit, and said memory; and a flash device for flash taking, said flash taking projecting flash light from said flash device to a subject so as to take said still image, wherein said plural operation sequences are a power-saving operation sequence and a normal operation sequence, wherein said power-saving operation sequence increases an output signal from said imaging device at a high gain upon flash taking, and decreases said flash amount of said flash device in accordance with said high gain, and wherein said normal operation sequence increases said output signal from said imaging device at a normal gain upon flash taking, and said flash amount is set to a standard level.
