Abstract: Examples of the present disclosure relate to a linear array of image sensor circuits including unused pixels. An example apparatus includes a linear array of image sensor integrated circuits, each integrated circuit including a plurality of pixels, each pixel including a light-sensitive element, and an unused pixel at a start of the integrated circuit. The apparatus further includes a processor, and a non-transitory machine readable medium storing instructions executable by the processor to receive programming instructions specifying a number of unused pixels associated with each integrated circuit, measure image data pixel signals from the linear array of image sensor integrated circuits, including the unused pixels, and disregard image data associated with the unused pixels.
