Exposure control system and method for an image sensor

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.

Image processing method and image capturing system

An image processing method includes the following steps. The first step is utilizing a linear image capturing apparatus with odd number of image capturing units to capture image portions of object. Next step is taking the image portions which are captured by the first-end and the right-end image capturing units as the reference and comparing the image portions which are captured by the central image capturing units with the reference so as to correct and eliminate the overlapped noise. Next step is interlacing and re-constructing the processed image portions which have no overlapped portions as the integrated image.
