US Patent Issued to Gigajot Technology on Oct. 21 for "Fast DCG pixel readout scheme for HDR CMOS image sensors" (California Inventor)

ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,452,562, issued on Oct. 21, was assigned to Gigajot Technology Inc. (Glendale, Calif.).

"Fast DCG pixel readout scheme for HDR CMOS image sensors" was invented by Dexue Zhang (Arcadia, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A dual operation correlated double sampling (CDS) readout circuit for implementation with a dual-conversion-gain (DCG) pixel is disclosed. The dual CDS readout circuit is capable of switching between a first readout mode that implements digital CDS and a second readout mode that implements analog CDS. In various implementations, the dual CDS readout circuit provides digital CDS operations when the DCG pixel outputs a h...
