Image sensing and recording device having a multilayer analog memory stacked on an image sensing array
First Claim
1. An image sensing and recording device comprising:
- a light-receiving element array section, having an image sensing surface on which a plurality of light-receiving elements are two-dimensionally arranged, for generating signal charges by photoelectrically arranged, for generating signal charges by photoelectrically converting light images incident on said image sensing surface in units of said plurality of light-receiving elements;
an analog memory section having a plurality of storage regions staked vertically in a multilayer structure on said light-receiving element array section, said plurality of storage regions including means for transferring the signal charges generated by said plurality of light-receiving element of said light-receiving element array section in a stacked direction thereof and sequentially storing the signal charges; and
a transfer section, stacked to sandwich said analog memory section between said transfer section and said light-receiving element array section, for reading out the signal charges, which are sequentially stored in said analog memory section, as time-serial image signals.

Abstract
An image sensing and recording device includes a light-receiving element array, an analog memory, and a transfer section which are integrally formed. The array has an image sensing surface on which a plurality of light-receiving elements are two-dimensionally arranged and generates signal charges by photoelectrically converting light images incident on the surface in units of the elements. The memory has a plurality of storage regions having a multilayer structure stacked on the array. The storage regions transfer the signal charges generated by the elements of the array in a stacked direction thereof and sequentially storing the signal charges. The transfer section is stacked to sandwich the memory between the transfer section and the array and is designed to read out the signal charges, which are sequentially stored in the memory, as time-serial image signals. A dark box incorporates the device. An optical lens is arranged in the dark box so as to form an object image on the surface of the device. A controller is arranged in the dark box so as to control generation of signal charges by the array of the device and to control transfer/storage of signal charges by the memory.
