摘要： Among other things, techniques and systems are provided for identifying when a pixel of an image sensor is in an idle period. A flag is utilized to differentiate when the pixel is in an idle period and when the pixel is in an integration period. When the flag indicates that the pixel is in an idle period, a blooming operation is performed on the pixel to reduce an amount of electrical charge that has accumulated at the pixel or to mitigate electrical charge from accumulating at the pixel. In this way, the blooming operation reduces a probability that the photosensitive sensor becomes saturated during an idle period of the pixel, and thus reduces the likelihood of electrical charge from a pixel that is not intended contribute to an image from spilling over and potentially contaminating a pixel that is intended to contribute to the image.

摘要： A method for operating image sensors is provided. The method for operating image sensors includes maintaining a charge transmission unit which transfers charges generated in a photoelectric conversion unit by responding to incident light to a charge detection unit in an inactive state; and toggling the charge transmission unit between an active state and an inactive state while a reset unit resets the charge detection unit, wherein the toggling is repeated multiple times while a reset unit which resets the charge detection unit is maintained in active state.

摘要： A solid-state imaging device having a pixel array section in which pixels including photoelectric conversion elements are arranged in a matrix form, and sweeping out unnecessary charges by setting a predetermined number, two or more, of adjacent rows or a predetermined number, two or more, of adjacent columns, in the pixel array section, to a single group, and by applying a shutter pulse in units of groups before storing signal charges, and sequentially reading the signal charges in the units of groups. In the solid-state imaging device, a pre-shutter pulse is applied to pixels belonging to at least a single row or a single column within a succeeding group and adjacent to a preceding group, prior to the shutter pulse, before a reading timing for the preceding group, to sweep out unnecessary charges stored in the pixels.

摘要： The invention relates to image sensors produced with CMOS technology, whose individual pixels, arranged in an array of rows and columns, each consist of a photodiode associated with a charge storage region which receives the photogenerated charge before a charge readout phase. To eliminate the risk of introducing kTC-type noise into the signal, during the reset of the storage zone at the end of a readout cycle, the invention proposes that the storage zone be divided into two parts one of which, adjacent to the reset gage, is covered by a diffused region of the same type of conductivity as the substrate in which the photodiode is formed, this region being brought to the fixed potential of the substrate, and the other of which is not covered by such a region and is not adjacent to the reset gate.
