摘要： Mechanical shutter devices for image sensors and associated methods are disclosed. In one aspect of the invention, an imaging system includes an image sensor having an array of pixels with photosensitive elements. The imaging system can further include a signal processing device coupled to the image sensor to receive signals from the image sensor. The system can still further include a shutter device having an open and a closed position. The shutter device can be located proximate to the photosensitive elements of the pixels so that when the shutter device is in the open position, light is allowed to reach the photosensitive elements of the pixels, and when the shutter device is in the closed position, all substantial amounts of light are prevented from reaching the photosensitive elements of the pixels. The image sensor can be configured to store the signals until the signal processing device can receive the signals.

摘要： In a CMOS image sensor, it is important to control the exposure time or gain. For varying changes in ambient light, the exposure time of the array must be changed. The present invention describes a method for controlling the exposure time or gain to ensure a smooth and fast change in the brightness of the obtained image. If the exposure time is the be decremented or incremented, then the gain control is increased or decreased, respectively to smooth out the changes in image brightness. This substantially reduces image flicker.

摘要： The present invention is directed to a single chip color MOS image sensor with a novel two-line reading structure which is compatible with MOS fabrication technology. The invention allows the simultaneous reading of line signals from two adjacent rows of pixels so that combinations of signals from pixels in adjacent rows may be obtained without the use of an external delay line device. The sensor includes a pixel array having superimposed thereon an improved color filter pattern and a two-line reading structure which may be doubled so as to provide four line signals. The reading structure includes sets of storage capacitors on which the pixel signals are stored, and a means for reading the signals from the capacitors in such a way that signals from pixels in adjacent rows may be combined. The approximate ratios of the colors in the improved color filter pattern are one-half green, one-fourth yellow, and one-fourth cyan.
