| titleOfInvention | Imaging device using pixel array to sense ambient light level & methods |
| abstract | Imaging devices and methods detect ambient light level using array pixels. In one embodiment, an imaging device includes an array of imaging pixels that are configured to acquire an image, and an array of dark pixels. A controller may cause at least one of the imaging pixels and of the dark pixels to image concurrently. A monitoring circuit may measure a difference between currents drawn by the imaging pixel and the dark pixel during the concurrent imaging. An indication of ambient light level can be generated according to the difference. The indication can be used as desired, for example to manage the brightness of the display screen. As such, no separate sensors are required, apart from the imaging array that is already provided for imaging. |
