  • Patent number: 6128036
    Abstract: A still picture recording digital camera including a light quantity limiter for interrupting incident light to the camera; an image pickup unit including a pixel for converting the incident light to an electric pixel signal and outputting the pixel signal as a digital image signal; a signal processor for generating a digital image signal having a predetermined format; a recording unit for recording the digital image signal output from the image pickup unit or the signal processor; the light quantity limiter limiting the incident light quantity to a predetermined quantity and then interrupting the incident light; the image pickup unit outputting a dynamic picture digital image signal when the light quantity limiter is limiting the incident light quantity, and outputting a still picture image signal after the light quantity limiter has interrupted the incident light; and the signal processor performing different signal processing operations when the signal processor has received a digital image signal for a dyn

  • Patent number: 5430499
    Abstract: An apparatus for correcting a vertical aperture of an image generates a vertical aperture correction signal having no line pair component contained therein from a signal read out at every frame from an imaging apparatus using an imaging device of pixel mixing system, the circuit arrangement for realizing the vertical aperture correcting apparatus being such that an original signal, a 2H (H is a horizontal scanning period) delay signal and a 4H delay signal are generated from the imaging device and a sum of the original signal and the 4H delay signal is subtracted from the 2H delay signal to thereby generate a vertical aperture correction signal and also the circuit arrangement being such that luminance signal spectral characteristics are approximated at every horizontal scanning by adjusting a gain of a signal read out from the imaging device.
