Title: The Innovations of Ketan Vrajlal Karia

Introduction

Ketan Vrajlal Karia is a notable inventor based in Cortland, NY (US), recognized for his contributions to imaging technology. With a total of nine patents to his name, Karia has made significant advancements in the field of solid-state imaging.

Latest Patents

Karia's latest patents include an image sensor ADC and CDS per column with oversampling. This innovation allows a solid-state imager to convert analog pixel values to digital form on an arrayed per-column basis. An N-bit counter supplies an N-bit DAC to produce an analog ramp output that varies according to the counter's contents. A latch/counter is associated with each respective column, and a clock supplies signals to the counter elements. The black level can be pre-set in the latch/counter or subtracted separately to reduce fixed pattern noise. Additionally, pixels can be oversampled to reduce thermal noise, and pixels sharing a common sense node may be binned together to enhance dynamic range.

Another significant patent is the sub-pixel array optical sensor. This invention improves the dynamic range of captured images by using sub-pixel arrays to capture light at different exposures. Each sub-pixel array can include multiple sub-pixels, including red, green, blue, and clear sub-pixels. The inclusion of clear sub-pixels allows for better low-light scene capture. Each sub-pixel array produces a color pixel output that combines the outputs of its sub-pixels, with the potential for different exposure times to further enhance dynamic range.
