Abstract
A dual sensitivity image sensor provides a standard mode and a high-sensitivity mode of operation via iSoC integration. In addition to boosting sensitivity, the high sensitivity mode also reduces temporal noise thereby optimally boosting the Signal-to-Noise Ratio (SNR) of the image sensor. The circuit does not significantly increase pixel complexity and requires minimal changes to the support circuits in the iSoC including the addition of support and control circuitry to facilitate seamless mode change.
