InactiveUS20060238643A1Improve captured image qualityReduce light interferenceTelevision system detailsPhotometry using reference valueExposure controlFlashlight
An exposure control system and method for an image sensor, which includes an image sensor, an illuminator, a controller and a light separator. The image sensor has plural photosensitive pixels in a two-dimensional matrix arrangement. When an exposure is operated in a sub-region of the plural photosensitive pixels, the illuminator produces a flashlight as a light source for exposure. The light separator eliminates light except the flashlight. The controller sequentially activates each row of pixels in the sub-region, and when each row of pixels is in an exposure state, the controller drives the illuminator to produce the flashlight.
