    • In order to select an image pickup area and execute an image pickup operation, or to perform an interlace operation, or to vary an image pickup frequency for one image pickup sensor, there is provided an image pickup apparatus constructed by a 2-dimensional solid state image pickup sensor in which pixel data instructed by horizontal and vertical shift registers is accessed and read out and a timing generator to drive the 2-dimensional solid state image pickup sensor. With respect to horizontal and vertical shift pulses which are supplied from the timing generator and drive horizontal and vertical shift registers of the 2-dimensional solid state image pickup sensor, periods of the horizontal shift pulses and/or the vertical shift pulses are made variable.
    • 为了选择图像拾取区域并执行图像拾取操作或执行隔行扫描操作或改变一个图像拾取传感器的图像拾取频率,提供了一种由二维固态构成的图像拾取装置 其中访问和读出由水平和垂直移位寄存器指示的像素数据的图像拾取传感器和用于驱动二维固态图像拾取传感器的定时发生器。 对于从定时发生器提供的水平和垂直移位脉冲以及驱动二维固态摄像传感器的水平和垂直移位寄存器,水平移位脉冲和/或垂直移位脉冲的周期是可变的。
