IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17991097 titled 'IMAGE SENSOR
Simplified Explanation
The patent application describes an image sensor that includes a pixel with two floating diffusions, generating two different pixel signals based on the charge quantities of the floating diffusions. These pixel signals are transmitted through a column line and processed by a readout circuit to generate an image signal based on comparison results with reference signals.
- The image sensor includes a pixel with two floating diffusions.
- It generates two different pixel signals based on the charge quantities of the floating diffusions.
- The pixel signals are transmitted through a column line.
- A readout circuit processes the pixel signals and generates an image signal.
