Patent ID: 7038183

Claim:
An image sensor device, comprising: a substrate, formed in CMOS technology with an integrated semiconductor structure (ASIC) and spatially adjacent pixels in each case being formed in the horizontal plane of the image sensor device, which pixels each have an optoelectronic transducer for converting incident light into an electrical current proportional to the incident quantity of light and also a charge store assigned to the optoelectronic transducer, the charge state of which charge store can be varied in a manner dependent on the light incident on the assigned optoelectronic transducer, wherein the charge store is a capacitor in which photocurrent output by the optoelectronic transducer is integrated during a predetermined measurement duration, and in that a first switching means is provided in each pixel that can be driven by a common control device, which said first switching means is coupled to the transducer and can be driven jointly for a plurality of pixels of the image sensor device; and a second switching means coupled to the transducer having a control input coupled to a bias voltage such that the second switching means switches from an off state to an on state in response to the first switching means switching from an on state to an off state, wherein the second switching means provides a current path through which photocurrent generated by the transducer is diverted while the first switching means is in the off state.
