Patent ID: 8446505

Claim:
An imaging apparatus for obtaining images, the imaging apparatus comprising: a pixel array to integrate electrical signals corresponding to incident light from a scene; a row decoder coupled to the pixel array, the row decoder to enable a selected row of pixels within the pixel array; a column decoder coupled to the pixel array, the column decoder to enable readout of a pixel in a selected column of the selected row within the pixel array; and a trigger circuit coupled to at least one of the decoders, wherein the trigger circuit is configured to generate one or more burst pulses to traverse through a corresponding number of decoder stages that correspond to pixels which are identified for discarding, wherein each burst pulse has a duration that is less than a stipulated minimum pulse duration of a typical decoder pulse of the decoders; wherein the trigger circuit comprises a row burst generator to generate the one or more burst pulses to traverse through the corresponding number of row decoder stages; and wherein the row burst generator is further configured to generate the one or more burst pulses to traverse through the corresponding number of row decoder stages prior to assertion of a first column select signal and a first column clock signal.
