PIXEL SENSOR USING A DUAL PIXEL ARRAY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240298097 titled 'PIXEL SENSOR USING A DUAL PIXEL ARRAY
The patent application describes an apparatus for providing a dual pixel array, which includes an array of pixels with multiple photodiodes in each pixel. These photodiodes generate a charge in response to incoming light and are connected to charge storage devices. The array consists of color photodiodes with chromatic filters and monochrome photodiodes with monochrome filters, each having a color-select switch and a monochrome-select switch. Analog-to-digital converters (ADCs) are connected to the charge storage devices of the photodiodes and convert stored voltages into pixel values in response to a control signal.
- Array of pixels with multiple photodiodes in each pixel
- Photodiodes generate charge in response to light

Original Abstract Submitted
one example apparatus for providing a dual pixel array includes an array of pixels, each pixel comprising a plurality of photodiodes, each photodiode configured to generate a charge in response to incoming light and connected to at least one charge storage device. the plurality of photodiodes comprises one or more color photodiodes each including a chromatic filter, a color-select switch, and having at least one associated monochrome photodiode with a monochrome filter and a monochrome-select switch. the dual pixel array further comprises one or more analog-to-digital converters (“adc”), each adc connected to at least one of the charge storage devices of the photodiodes via the respective select switch, configured to selectively convert one or more stored voltages into a pixel value in response to a control signal. the color photodiodes and the monochrome photodiodes are arranged according to an arrangement.
