Title:
APS CELL WHOSE SIGNA/NOISE RATIO IS IMPROVED
Document Type and Number:
Japanese Patent JP2005354702
Kind Code:
A
Abstract:
To provide an APS cell which compensates phenomenon in which signal/noise ratio gets worse when an area of predetermined region (light-receiving unit) installed in the APS system decreases in order to hold outdoor daylight.
The APS cell processes a small scale of potential formed by a light-receiving unit after making it amplify using a potential amplifying device 220. The APS cell has a light-receiving instrument 210 and the potential amplifying device 220. The light-receiving instrument 210 receives light and produces a predetermined potential corresponding to the received light. The potential amplifier 220 receives and amplifies any one potential among potentials formed with the euphotic instrument 210.
