    • 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.
    • 用于使用高分辨率电荷耦合固态成像装置拍摄静止图像的高分辨率相机。 成像装置包括以行和列排列的多个光电转换元件,其中每列被分成四个光电元件的重复序列,每个元素对应于像素和四个场中的一个。 在每个光电元件列之间形成多个垂直电荷传输路径,并且横向电荷传输路径连接到每个垂直电荷传输路径的端子部分。 水平电荷传输路径包括第一和第二水平寄存器。 在与四个场中的一个相对应的光电元件处产生的像素信号在对应于一个场的场移位周期中传送到传送元件。 此后,根据驱动信号将信号转移到水平电荷传输路径,然后在每一行由水平电荷传输路径水平传输,以读取并存储用于一个场的信号。 四个场的信号被存储在存储器的相应的存储区域中。 在一个实施例中,信号由每帧读取,并且对应于第一和第二水平寄存器之一的两个场的信号被提供给电子取景器以进行显示。 根据快门的动作,根据四个场的信号记录显示图像的静止图像。 在另外的实施例中,两个水平寄存器可操作以在高分辨率模式期间输出信号,并且只有一个水平寄存器可操作以在低分辨率模式期间输出信号。
