摘要： An electronic imaging system includes a CCD image sensor arrangement having a two dimensional array of pixels. The pixel array converts light incident thereon to an electric signal. The pixels are arranged in a plurality of horizontal rows or lines, the lines being arranged vertically. A control arrangement selectively controls operational modes of the system. One mode provides for sequential scan reading out of pixel signals for entire lines of the CCD for still picture recording. Another mode provides for reading out pixel signals concerning k (k is a positive integer) vertically continuous lines of the CCD for still picture recording or dynamic image processing. Thus it is possible to provide a high pixel density solid-state image sensor output at a high frame rate without use of any high drive frequency.

摘要： An imaging apparatus includes an interline type CCD image sensor having 1,000,000 or more pixels, which has a Bayer configuration color filter suitable for reading all pixel signals in a line-sequential scanning manner. The imaging apparatus drives the CCD image sensor in a high speed mode usually, and in a high quality image mode only for a trigger depression. In the high speed mode, the CCD image sensor outputs pixel signals for one line at intervals of three lines in the vertical direction. During the high speed mode operation of the CCD image sensor, images are displayed on a liquid crystal display portion at a frame rate of 60 frames/second, the images being recognized by the human eyes as a dynamic image, i.e., a motion picture.

摘要： A CCD imaging element 12 has a two-dimensional array of a plurality of pixels in the horizontal and vertical directions. A read-out mode switching circuit switches a full read-out mode and a horizontal line thinning-out mode with respect to the imaging element 12 one over to the other. A read-out circuit reads out an image signal from the imaging element 12. A defective pixel compensation circuit 15 executes compensation for defective pixels on the basis of adjacent pixel signals thereto. In the full read-out mode, the defective pixel compensation is executed by using four normal pixels adjacent to the defective pixel in the horizontal and vertical line directions. In the thinning-out read-out mode, the defective pixel compensation is executed by using two normal pixels adjacent to and on opposite sides of a horizontal line defective pixel in the horizontal line direction, said two normal pixels lying along the same horizontal line as said defective pixel.

摘要： A point defect and a line defect in a captured image resulting due to an imaging element defect in a digital camera are interpolated. A defect correction circuit of a digital camera simultaneously corrects a point flaw, a vertical line flaw, and a horizontal line flaw in a captured image. In consideration of cases in which a point flaw and a vertical line flaw are present adjacent to each other, the defect correction circuit executes predetermined difference calculations using pixels surrounding a target pixel to be corrected and determines an interpolation pattern based on a comparison of magnitude among the difference calculation values. The defect correction circuit also selects, for interpolation, an interpolation pattern from among interpolation patterns prepared in advance based on an adjacent pattern of the point flaw and line flaw. The adjacent pattern is detected by a defect decode circuit 78.
