Abstract
A pixel array in an image sensor includes multiple pixels. The pixel array includes vertical shift registers for shifting charge out of the pixel array. The vertical shift registers can be interspersed between the pixels, such as in an interline image sensor, or the photosensitive areas in the pixels can operate as vertical shift registers. The pixels are divided into blocks of pixels. One or more electrodes are disposed over each pixel. Conductive strips are disposed over the electrodes. Contacts are used to connect selected electrodes to respective conductive strips. The contacts in at least one block of pixels are positioned according to one contact pattern while the contacts in one or more other blocks are positioned according to a different contact pattern. The different contact patterns reduce or eliminate visible patterns in the contact locations.
