Abstract
A pixel within a pixel array of an integrated-circuit image sensor outputs an analog signal representative of accumulated photocharge. First and second analog-to-digital conversions of the analog signal are initiated while the pixel is outputting the analog signal, the first analog-to-digital conversion corresponding to a low-light range of photocharge accumulation within the pixel and the second analog-to-digital conversion corresponding to a brighter-light range of photocharge accumulation within the pixel.
