  • Patent number: 5682203
    Abstract: A solid-state image sensing device including a plurality of photo cells provided on a substrate and a plurality of micro condenser members each provided on a corresponding photo cell. The interval at which the micro condenser members are arranged at a central portion of the substrate differs from the interval at which the micro condenser members are arranged at a peripheral portion. Further, a center of the micro condenser member and a center of the photo cell may coincide with each other at the central portion of the substrate and may shift from each other at the peripheral portion thereof. Also, a power of the micro condenser members arranged at the central portion of the substrate may differ from a power of the micro condenser members arranged at the peripheral portion thereof.

  • Patent number: 5585848
    Abstract: An apparatus for driving a solid-state image sensor includes a sensor portion for performing a photoelectric conversion, a vertical transfer register for reading information from the sensor portion, a memory for storing information from the vertical transfer register, and an eliminating unit for eliminating information from the sensor portion, wherein the information in the sensor portion is eliminated by the eliminating unit intermittently two or more times in one field interval, whereby information storage time is controlled. In one field interval, operation of the eliminating unit is performed successively every time T.sub.2 after time T.sub.1 from a vertical synchronizing signal, the information from the sensor portion is read in the vertical shift register successively, at every operation of the eliminating unit, a time T.sub.3 after the end of this operation, and the first time T.sub.1, second time T.sub.2 and third time T.sub.

  • Patent number: 5546122
    Abstract: This is a film image input system wherein an image of the developed still photo film is made to focus on an image sensing plane of a charge coupled device through a taking lens to be converted into electric signals and the electric signals are input in a video monitor. The film image input system comprises: a zoom driving part for changing the image magnification of the taking lens; a scan mechanism for moving an image taking position on the film by the taking lens; and a control part for controlling the scan mechanism in such a manner that the moving speed of the scan mechanism is decreased with the increase in the image magnification of the taking lens and making the moving speed of a screen on the video monitor constant during scan.

  • Patent number: 5526049
    Abstract: An automatic focus circuit for use with a video camera comprises an analog to digital converter which converts an analog luminance signal provided from an image signal processing circuit into a digital luminance signal, a microcomputer for controlling the automatic focus unit using an integrated luminance value which is integrated in an integrating circuit, and an area dividing circuit for horizontally and vertically dividing a screen of a video camera monitor. The automatic focus operation is easily performed by using the integrated digital luminance value as stored in a memory circuit. Accordingly, the automatic focus circuit simplifies the constitution and accuracy of the automatic focus.

  • Patent number: 5497192
    Abstract: A video signal processing apparatus for correcting vibration effects in a video camera that has a CCD image pickup device having a number of lines greater than the number of lines of the standard NTSC television system. The lines used to generate the image are shifted during the vertical blanking interval to correct for vibrations of the video camera, and the overflow charges which are caused by transferring the CCD image pickup device at a high speed during the blanking period are absorbed into a semiconductor drain element arranged in parallel with the horizontal transfer register of the CCD image pickup device. Defective pixels in the image pickup device are compensated by storing the addresses of defective pixels and interpolating at those positions, during vibration correction the addresses of the defective pixels are shifted to correspond to the amount of vibration correction.
