Frame shuttering scheme for increased frame rate
First Claim
Patent Images
1. An apparatus, comprising:
- an array of photoreceptor pixels, each pixel of the array including a photoreceptor part and control part which selects some aspect of an associated photoreceptor pixel for readout; and
a control element, which selects only specified ones of the photoreceptor pixels in a specific row for integration at any given readout time such that at least each two adjacent pixels integrate at different times.

8. A method, comprising:
-
integrating light indicative of a scene being imaged in a plurality of pixels forming an array, said integrating comprising integrating each of said pixels in said array beginning and ending at substantially the same time but in at least two different groups; and
forming at least two different image fields from the at least two different groups. - View Dependent Claims (9, 10, 11, 12, 13)

14. An apparatus, comprising:
-
an array of active pixel sensors, each including a photoreceptor portion, and a control portion, said control portion enabling activation of said photoreceptors between an integrating state and into a non integrating state, and also enabling transfer of charge from said photoreceptor to an output; and
a controller, controlling said photoreceptors to integrate in a plurality of different periods, such that at least a first group of photoreceptors integrates during a different time than a second group of said photoreceptors. - View Dependent Claims (15, 16, 17, 18)
