Abstract
Image sensor systems and methods that mitigate the effects of electronic image sensor persistence are provided. The mitigation of persistence is achieved by flooding the pixels of the image sensor with light, saturating all of the pixels, prior to the collection of desired image data. Moreover, after saturating the pixels, but prior to collecting the desired image, the image sensor is reset and operated to take an image of a black scene. Due to persistence from the prior saturation step, the image of the black scene appears as a gray image. The image sensor is then optionally reset and is again saturated. After another reset operation, a desired image is obtained. The gray image is then subtracted from the desired image, to substantially correct for the effects of persistence in that image.
