Patent ID: 8045030

Claim:
An imaging device comprising: a solid element including an imaging unit having a plurality of pixel cells having light receiving elements and MOS type transistors connected in series for operating said MOS type transistors in a weak inversion state to convert photo currents to flow through said light receiving elements in accordance with an incident light into voltages, thereby to output said voltages, a reset voltage generating circuit for generating reset voltages to initialize the output voltages of said light receiving elements, and decoders for feeding said reset voltages for a reset period to said plurality of pixel cells to initialize the output voltages of said light receiving elements, and for feeding drive voltages to operate said MOS type transistors for an exposure period in the weak inversion state to said plurality of pixel cells; and a temperature detecting unit for detecting a temperature of said solid imaging element, wherein said reset voltage generating circuit generates the reset voltages corresponding to the temperature at different times, on the basis of the detection results of said temperature detecting unit; a table stored with a plurality of temperatures of said solid imaging element and control values corresponding to individual temperatures; and a setting unit for reading the control values corresponding to the temperatures at the different times from said table, on the basis of the detection results of said temperature detecting unit thereby to set the read control values in said reset voltage generating circuit, wherein said reset voltage generating circuit generates the reset voltages in accordance with the control values set by said setting unit.
