Abstract
Various embodiments of the present technology may comprise methods and apparatus for a CCD image sensor. The image sensor may comprise a center channel disposed along a horizontal center line of the pixel array for collecting and transferring charge. The center channel is electrically coupled to a lateral overflow drain. In various embodiments, the image sensor may comprise a light shield under a gap between neighboring microlenses, such as a gap along the center line, to block light, such as to maintain a uniform, spatial sampling pattern across the device. In various embodiments, the image sensor may comprise a barrier region disposed between the center channel and the lateral overflow drain, for example to prevent charge from the lateral overflow drain being injected back into the center channel and adjacent pixels.
