  • Electronic camera that sets an upper limit of an exposure time during dark image capture
    Patent number: 7274392
    Abstract: An electronic camera according to the present invention includes: an image-capturing element that outputs image-capturing signals; a shutter device that allows subject light pass through to the image-capturing element or shields the image-capturing element from the subject light; an image-capturing circuit that engages the image-capturing element in an image-capturing operations over a predetermined length of time to output to a first image-capturing signal while the subject light is allowed to pass through to the image-capturing element and also engages the image-capturing element in an image-capturing operation over a predetermined length of time while the image-capturing element is shielded from the subject light; a signal correction circuit that executes a signal correction by subtracting the second image-capturing signal from the first image-capturing signal; and a control circuit that controls the image-capturing circuit so as to set an upper limit to the length of the image-capturing operation executed
    Type: Grant
