IMAGE PICKUP DEVICE THAT IS PROVIDED WITH PERIPHERAL CIRCUITS TO PREVENT CHIP AREA FROM BEING INCREASED, AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18155189 titled 'IMAGE PICKUP DEVICE THAT IS PROVIDED WITH PERIPHERAL CIRCUITS TO PREVENT CHIP AREA FROM BEING INCREASED, AND IMAGE PICKUP APPARATUS
Simplified Explanation
The abstract describes an image pickup device that aims to reduce the size of peripheral circuits without compromising the performance of the pixel section, while also keeping costs low. The device consists of two semiconductor substrates and includes a pixel section with photo diodes for converting light into electric charges, floating diffusions for temporarily storing the charges, and amplifiers for outputting signals based on the potential of the floating diffusions. Column circuits are connected to vertical signal lines for processing the signals from the pixel section.

Original Abstract Submitted
An image pickup device which suppresses an increase in chip area of peripheral circuits without degrading the performance of a pixel section and makes it possible to prevent costs from being increased. The image pickup device includes a first semiconductor substrate and a second semiconductor substrate. A pixel section includes photo diodes each for generate electric charges by photoelectric conversion, floating diffusions each for temporarily storing the electric charges generated by the photo diode, and amplifiers each connected to the floating diffusion, for outputting a signal dependent on a potential of the associated floating diffusion. Column circuits are connected to vertical signal lines, respectively, for performing predetermined processing on signals output from the pixel section to vertical signal lines.
