Abstract: An image sensor with a light reader circuit coupled to a pixel array. The light reader circuit retrieves a first image and a second image generated by the pixel array. The image sensor may also include a memory controller and/or data interface that transfers the first and second images to an external device in an interleaving manner.

Abstract: An image sensor with a plurality of photodiodes that each have a first region constructed from a first type of material and a second region constructed from a second type of material. Located adjacent to the first region and between second regions of adjacent photodiodes is a barrier region. The photodiodes are reversed biased to create depletion regions within the first regions. The barrier region limits the lateral growth of the depletions regions and inhibits depletion merger between adjacent photodiodes.

Abstract: An image sensor with a plurality of photodiodes pixels. At least one of the photodiodes pixels includes a reflective element that prevents light from traveling onto an adjacent photodiode pixel. The reflective element may be a floating contact adjacent a routing wire of the image sensor. The reflective element may have an aspect ratio that maximizes the reflective surface of the element.

Abstract: An image sensor that has a pixel array with a plurality of pixels. Each pixel includes a photodiode. The sensor includes a row decoder and a light reader that are connected to the pixel array by a plurality of conductive traces. In the outer areas of the pixel array the locations of the traces is shifted to optimize the amount of light that impinges onto the photodiodes.

Abstract: An image sensor that has a temperature sensor. The temperature sensor senses the temperature of a pixel array of the image sensor. The sensed temperature is used to scale a dark frame image generated by the pixel array. The scaled dark frame image is subtracted from a light image frame generated by the pixel array. The scaled dark image frame compensates for temperature variations in the pixel array. The scaled dark image frame may be generated by multiplying the dark frame by a scale factor(s). The scale factor may be computed from an equation or determined from a look-up table. The equation or look-up table may compensate for thermal gradients across the pixel.
