Abstract: A CMOS image sensor with reducing interconnections is provided. The CMOS image sensor may include a first row of pixels that includes a first pixel. The first pixel may include a first plurality of photodiodes and a first plurality of transfer gates. Each of the first plurality of photodiodes may be associated with a corresponding one of the first plurality of transfer gates. The CMOS image sensor may include a second row of pixels that includes a second pixel. The second pixel may include a second plurality of photodiodes and a second plurality of transfer gates. Each of the second plurality of photodiodes may be associated with a corresponding one of the second plurality of transfer gates. A first one of the transfer gates of the first plurality of transfer gates may be coupled to a first one of the transfer gates of the second plurality of transfer gates.

Abstract: A camera using a CMOS image sensor based on a shared pixel array technology avails both high definition (HD) and ultra-high definition (UHD) resolution mode formats. Dynamic pixel management allows for both sequential and binned timing formats of pixel signals using switched capacitor noise reduction techniques. When UHD resolution mode is selected, noise can be reduced using both digital double sampling (DDS) or differential digital double sampling (dDDS), and when HD resolution mode is selected noise can be reduced using DDS. Additionally, both rolling shutter and global shutter modes can be selected when HD resolution mode is selected.

Abstract: An apparatus for HDR image processing is provided. The apparatus determines an imaging sensitivity value. The apparatus then compares subsets of imaging information with the determined imaging sensitivity value and applies a gamma correction to each subset of imaging information using a gamma low contrast curve or a gamma high contrast curve based on the comparison to obtain the gamma corrected subset of imaging information.

Abstract: A method for performing differential double sampling and a CMOS image sensing device for performing the same. In one example, the CMOS image sensing device includes a pixel array include a multitude of pixels with each pixel formed by a plurality of photodiodes, a floating diffusion point and a plurality of transistors electrically coupled the plurality of photodiodes. Moreover, a column readout circuit with four storage capacitors is selectively coupled to the pixel array by switches so that the storage capacitors can store sampled pixel values. A control circuit connected to the pixel array and the column readout circuit selectively activates the transistors to output to the column readout circuit sampled dark value and bright values of one photodiode and a sampled double bright value of the one photodiode and one additional photodiode.
