20100277624 | System and Method for Canceling Dark Photocurrent in a Color Sensor Circuit - A system and method for canceling dark photocurrent in a color sensor circuit is disclosed. A color sensor is described including a color sensor circuit, a dark color sensor circuit, and a differential amplifier circuit. The color sensor circuit receives photocurrent from a color component of a light input. The color sensor circuit outputs a first voltage indicating intensity of the color component. The dark color sensor circuit receives dark photocurrent and outputs a second voltage indicating an offset voltage. The differential amplifier circuit is coupled to the color sensor circuit and to the dark color sensor circuit. The differential amplifier circuit receives the first and second voltages and outputs a final output that cancels contributions of the offset voltage in the first voltage due to the dark photocurrent. | 11-04-2010 |

20120033110 | LIGHT OR RADIATION IMAGE PICKUP APPARATUS - The radiation image pickup apparatus of this invention can obtain an accurate temperature characteristic of dark current noise, the dark current noise being caused by dark current flowing through an X-ray conversion layer, by obtaining dark image signals at varied times for accumulating in capacitors charge signals converted by an X-ray converting layer. Consequently, the noise due to the dark current can be removed with high accuracy by removing periodically acquired offset signals from X-ray detection signals acquired at a time of X-ray image pickup, and correcting variations of the dark current noise due to a difference in temperature between a time of offset signal acquisition and the time of X-ray image pickup, using the temperature characteristic of the dark current noise. | 02-09-2012 |
20130033625 | CAMERA - A camera a has an image sensor; an exposure controller that conducts a main exposure and a dark exposure, in order, when a long-exposure shooting is carried out; an image signal processor that processes image-pixel signals that are generated by the main exposure and are read from the image sensor; and a noise reduction processor that reduces dark current components in the image-pixel signals on the basis of dark current components in the dark exposure. The exposure controller operates the image sensor for heating between the main exposure and the dark exposure. | 02-07-2013 |
20150319385 | Sensor Dark Pixel Offset Estimation - Examples of systems and methods to provide estimates of dark current for pixels of a photosensor as a function of the temperature of the sensor and the gain applied to the photosensor are described. In various implementations, the dark current estimated for each pixel can depend at least partly on a global scale factor and a global bias that depend on temperature and gain and a temperature-independent and gain-independent offset value for each pixel. The scale, bias, and offsets may be determined from multiple dark field images taken by the sensor over a range of operating temperatures. In some cases, the scale and bias can be determined using a subset of less than all the image pixels. Scale and bias derived for a particular sensor can be used in the calibration of different sensors. | 11-05-2015 |
