<p>A pixel array (550) has a plurality of pixels arranged in a set of four pixels, each having respective photosensors (501, 502, 503, 504). Each set of pixels shares a readout circuit (710); the readout circuit (710) includes a linearly-extending trunk located within the area between the first pair of photosensors (501, 503) and the second pair of photosensors (502, 504). Each pixel has a transfer gate (505, 506, 507, 508), at least a portion thereof being at an angle with respect to the photosensors (501, 502, 503, 504). The transfer gates (505), (506, 507, 508) are shared among two adjacent pixels in a row. This readout circuit layout increases the pixel fill factor.</p> |
