  • Patent number: 6577341
    Abstract: An imaging apparatus reduces the influence of the movement of hands and of the motion of an object on a high resolution picture image. Picture image light from the object passes through an optical system and light-transmitting domains of a color filter provided at the light incident side of an imaging device. The light-transmitting domains transmit only predetermined chromatic lights of the picture image light to input to corresponding photo-receiving domains of the imaging device. The imaging device is a two-picture element mixed reading type device. In a high resolution mode, an image forming point of the picture image light is moved to two places in parallel, and the picture image light is formed at each image forming point to image the picture image light. Then, the signal processing circuit combines the two original picture image signals whose image forming points during the imaging operation are different to generate a single output picture image signal.

  • Patent number: 6456324
    Abstract: An image pick-up apparatus is provided with: a charge-coupled device for picking up imaging light from a subject and forming image data; an image-shift mechanism for shifting the charge-coupled device to a plurality of relative positions with respect to the imaging light so as to allow the charge-coupled device to form the image data at the relative positions; an LPF constituted by a filter for removing a spatial frequency component that appears due to a light-quantity difference between a plurality of pieces of image data generated by the charge-coupled device through the image-shift mechanism; and a memory control section for combining the plurality of image data. With this arrangement, it is possible to suppress a striped pattern due to the light-quantity difference, and consequently to improve the image quality.

  • Patent number: 6108036
    Abstract: A single imaging apparatus is adapted to pick up both a motion image and a still image. In an imaging apparatus 1, image light from an object is separated into multiple monochromatic image light components by an optical system 3 and then imaged by an imaging means 4 for generation of an original image signal. The imaging apparatus 1 switches an imaging mode depending upon an output mode. The optical system 3 switches the sate of a variable spatial filter 18 depending upon an imaging mode thereby changing an effect for limiting the spatial frequency. In an output mode for motion images, an interpolative synthesizer circuit 7 generates the output image signal from a single original image signal. In an output mode for still image, an image shift mechanism 19 parallely shifts the optical axis of the incoming image light while the imaging means captures the original image light multiple times so that an output image is produced from these original image signals.

  • Patent number: 5668746
    Abstract: Low-frequency components of a reproduced modulated signal is attenuated by an analog high-pass filter. The modulated signal with its low-frequency components attenuated is converted into a digital signal by means of an A/D converter. Then, the digital signal is directly introduced to a finite impulse response digital filter to be subjected to reproduced waveform equalization. Thereafter, the attenuation of the low-frequency components effected by the analog high-pass filter is compensated in an infinite impulse response digital filter.
