Electronic devices may include image sensors having image pixel arrays with image pixels arranged in pixel rows and pixel columns. Each pixel column may be coupled to an active and an inactive current supply circuit. Each active current supply circuit may form a portion of a current mirror circuit that includes a common current source and a common input transistor. Each active current supply circuit may include a mirror transistor for mirroring current that flows through the common input transistor and a permanently enabled enabling transistor for activating that mirror transistor. Mirrored current that flows through a particular active mirror transistor may be supplied to image pixels in the pixel column associated with that particular mirror transistor. Each inactive current supply circuit may include a mirror transistor coupled to the input transistor and a permanently disabled enabling transistor.

An imager may include depth sensing pixels that provide an asymmetrical angular response to incident light. The depth sensing pixels may each include a substrate region formed from a photosensitive portion and a non-photosensitive portion. The depth sensing pixels may include mechanisms that prevent regions of the substrate from receiving incident light. Depth sensing pixel pairs may be formed from depth sensing pixels that have different asymmetrical angular responses. Each of the depth sensing pixel pairs may effectively divide the corresponding imaging lens into separate portions. Depth information for each depth sensing pixel pair may be determined based on the difference between output signals of the depth sensing pixels of that depth sensing pixel pair. The imager may be formed from various combinations of depth sensing pixel pairs and color sensing pixel pairs arranged in a Bayer pattern or other desired patterns.

An imaging device and method for operating the device. The device comprises a pixel array having a plurality of pixels arranged in rows and columns and a plurality of readout circuits for the pixels. A reset circuit in one readout circuit is simultaneously operated with a row select circuit in another readout circuit using a common select line. A transfer select circuit may also be simultaneously operated with the common select line.

A pixel circuit configured for optionally connecting the floating diffusion region of the pixel circuit to a floating diffusion region of another pixel circuit. Methods of using the pixel circuit include averaging or summing multiple photosensor outputs in the combined floating diffusion regions, varying the conversion gain of a pixel circuit floating diffusion region, and utilizing multiple readout circuits to readout charges transferred from a single photosensor to the combined floating diffusion regions. A method of window-of-interest averaging that utilizes the combined floating diffusion regions is also disclosed.

An electronic imager includes a plurality of pixels having photosensors for accumulating charge corresponding to individual pixel values of a sensed image. Each of the pixels includes an anti-blooming function which allows charge in excess of a predetermined amount to be drained from the photosensor thus reducing the charge from the pixel that migrates to adjacent pixels. The imager also includes circuitry which controls the anti-blooming function in response to image intensity to reduce dark current in the imager caused by the anti-blooming function.

An imaging device and method for operating the device. The imaging device comprises a pixel array having a plurality of pixels arranged in rows and columns. At least one pixel of the array comprises a photosensor and a first reset circuit responsive to a first reset control signal for resetting the photosensor. A first terminal of the first reset circuit is coupled to the photosensor and a second terminal of the first reset circuit is configured to receive a first resetting voltage from a control line.
