Abstract: A device that includes a pixel array and a sample and hold circuit configured to provide sampled current to the pixel array wherein the sample and hold circuit includes a first transistor, a capacitor and a pair of current mirrors. The pair of current minors are connected to the first transistor and wherein the capacitor is connected to a drain of the first transistor.

Abstract: The invention provides a method for providing an image, the method includes: exposing a first group of pixels located at a first location to light, during an intermediate exposure period, to provide analog signals representative of the light; and transferring the analog signals to a second group of pixels located at a second location; whereas a relationship between the first and second locations is responsive to an estimated inter-image shift; then further exposure of the second group of pixels etc.

Abstract: An image is generated by receiving a first image that is acquired during a first exposure period and defining the first image as a reference image; defining multiple reference regions of interest within the reference image, wherein an aggregate number of pixels within the multiple reference regions of interest is substantially smaller than a number of pixels of the first image; receiving a second image that is acquired during a second exposure period; and updating the reference image in response to a content of the reference image, content of the second image and a first type of spatial relationship (e.g., a shift) defined between the reference image and the second image, wherein the shift is defined in response to multiple spatial relationships between the multiple reference regions of interest and between multiple regions of interest of the second image.
