摘要

(57) camera that can meet the standard United States [summary] high-definition television (HDTV) is described. The camera generates a display of 720 pixels × 1280 pixels at 60 frames per second. In a preferred embodiment, as an image sensor, three-phase buried channel CCD frame only transfer that can move the charge storage region from the image forming region is provided in a short blank period provided by the lens shutter. The image sensor has an arrangement of electrodes spaced, these electrodes, transfer charge to be electrically connected to the flow divider image sensor. However, the arrangement of electrodes in each of a plurality of pixels The same, whereby these pixels, so as to reduce the resistance that is present during the transfer charge to the storage area from the image forming area, and is disposed to an image forming area. In addition, and to minimize the effect on the reproduced image of the dark current from the storage section, the image sensor to provide amplification of the image before substantial noise is introduced. A further embodiment is described, in which, i) reaction prevention coating, to minimize the distortion of the reproduced image, without contaminating the camera, obtained, iii) the image sensor ii) the camera to reproduce an image at different frame rates one of the interlaced scanning mode or scanning mode even can operate progressively to.
