Title:
SOLID STATE IMAGE PICK-UP DEVICE
Document Type and Number:
Japanese Patent JPS59132162
Kind Code:
A
Abstract:

PURPOSE: To remove a smered component stored in vertical signal lines during reading and storing periods, by resetting the vertical signal lines immediately before reading photoelectric conversion signals to the vertical signal lines.

CONSTITUTION: A plurality of photoelectric conversion elements 15 are arranged on a semiconductor substrate. A horizontal scanning circuit 11 and a vertical scanning circuit 12 are provided in order to read a photoelectric conversion outputs out of the conversion elements 15. The vertical scanning circuit 12 sequentially selects vertical scanning lines and turns ON MOS switches 17. The horizontal scanning circuit 11 sequentially selects horizontal scanning lines 43 and turned ON MOS switches 44. In a solid state image sensor device constituted in this way, a reset power source 45 and reset MOS switches 41 are provided. The switches 41 are turned ON immediately before the photoelectric conversion signals are read to vertical signal lines 18, and reset the signal lines 18. Therefore, a smered component stored in the signal lines 18 during the reading and storing periods can be removed.
