  • Patent number: 6519000
    Abstract: An image pickup apparatus comprises: an interline-type image-sensing device, which includes: a plurality of photoelectric conversion elements, and a vertical transfer block for transferring charges received from the plurality of photoelectric conversion elements located along one direction. The vertical transfer block includes transfer electrodes disposed such that at least three transfer electrodes are disposed for each of the plurality of photoelectric conversion elements. At least one horizontal transfer block transfers charges received from the vertical transfer block along a direction crossing the one direction, and mode switching means switches a drive mode to drive the image-sensing device either in a still picture mode or in a moving picture mode.

  • Patent number: 6101292
    Abstract: An image processor in which desired image data can be read and displayed at a high speed when editing image data. Original image data is input, and a data conversion block generates standard image data whose capacity is smaller than that of the original image data. The generated standard image data and the input original image data are stored in an image data block so as to correspond to each other. When reading of image data stored in the image data block is instructed, the corresponding standard image data is read and is displayed on a page editing picture surface.

  • Patent number: 5867627
    Abstract: Apparatus and method for recording and/or reproducing an image frame in plural blocks utilizes a memory for storing an image signal for one field. The image signal for one field is then divided into n blocks by reading the image signal from the memory n times where n is an integer equal to at least two. The n divided image signals are then subjected to one-channel signal processing, and the respective image signals subjected to the signal processing are then recorded on a recording medium sequentially in different tracks. During reproduction, if little time is available, only selected ones of the n blocks are read and the entire image is interpolated therefrom.
