摘要:
A high definition camera for photographing still pictures using a high resolution charge coupled solid-state imaging device. The imaging device includes a plurality of photoelectric conversion elements arranged in rows and columns, wherein each column is divided into repeating sequences of four photoelectric elements, each element corresponding to a pixel and one of four fields. A plurality of vertical charge transfer paths are formed between each column of the photoelectric elements and a horizontal charge transfer path is connected to a terminal portion of each of the vertical charge transfer paths. The horizontal charge transfer path includes first and second horizontal registers. Pixel signals generated at photoelectric elements corresponding to one of four fields are transferred to transfer elements in a field shift period corresponding to the one field. Thereafter, the signals are transferred toward to the horizontal charge transfer path in accordance with drive signals and are then horizontally transferred by the horizontal charge transfer path at every row to read and store the signals for the one field. The signals of the four fields are stored in respective memory areas of a memory. In an embodiment, signals are read by every frame and the signals of two fields, corresponding to one of the first and second horizontal registers, are supplied to an electronic viewfinder for display. A still image of the displayed image is recorded in accordance with signals of four fields upon actuation of a shutter. In an additional embodiment, both of the horizontal registers are operable to output signals during a high resolution mode and only one of the horizontal registers are operable to output signals during a low resolution mode.
