Electronic imaging system with row-wise or column-wise image sensor reset synchronized to a mechanical shutter

摘要

A camera includes an image sensor having an array of light measuring elements; a shutter curtain which moves in a predetermined direction and with a predetermined speed to block light from reaching the image sensor; and a reset mechanism for resetting the light measuring elements to a nominal state; wherein, when the reset mechanism initiates operation at a first time to reset incrementally the elements of the array with substantially the same predetermined direction and with substantially the same predetermined speed as the shutter curtain for starting the light measuring process, the shutter curtain moves at a second time to block light from the image sensor which effectively stops the light measuring process
