PROBLEM TO BE SOLVED: To provide an imaging apparatus and method which can realize low power consumption, while maintaining photographing response in a low power consumption mode for stopping a screen display, reduce power consumption of an imaging element by driving a CCD at a slow clock, realize quick response by continuously executing photometry, and reduce power consumption by stopping image processing of an image processing unit and operation of a display device. SOLUTION: The imaging apparatus is provided with an analog image processing means, including a solid-state imaging element, a timing generator for driving the imaging element, and an A/D converter; a photometric means for extracting the luminance value to be used for AE from a digital image signal; a digital image signal processing means; an image display means for displaying image; and a clock generating means for supplying clocks to the imaging element, the analog image processing means and the image processing means. In this imaging apparatus, the clock generating means can change the clock frequency and changes the frequency, depending on the state of the screen display. COPYRIGHT: (C)2007,JPO&INPIT |
