1. An image pickup device characterized by comprising:

  • image pickup means for outputting image pickup results by XY address control, said image pickup means including a plurality of photoelectric conversion units arranged in a form of a matrix; and

    a peripheral circuit retained integrally with said image pickup means, said peripheral circuit being connected to said photoelectric conversion units by a wiring layer formed on a surface on an opposite side from a light receiving surface of said image pickup means,the image pickup results of said image pickup means being processed and output by said peripheral circuit,wherein said peripheral circuit includesimage compressing means for data-compressing and outputting at least said image pickup results in each predetermined processing unit, andcontrolling means for controlling a data compression ratio of said image compressing means,said peripheral circuit is supplied with said image pickup results from said image pickup means in units of blocks formed by dividing an effective image area in a horizontal direction and a vertical direction, and sequentially data-compresses said image pickup results, andwithin one frame, on a basis of an amount of code generated by data compression of one block by said image compressing means, said peripheral circuit changes the data compression ratio when at least a next block is data-compressed by said image compressing means, andsaid image pickup means outputs the image pickup results of said photoelectric conversion units with said blocks as units in a sequence corresponding to the data compression by said image compressing means.
