IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240129649 titled 'IMAGE SENSOR
Simplified Explanation
The abstract describes an image sensor with a unique pixel array configuration and row driver control for transferring charges between floating diffusions.
- Pixel array with first and second floating diffusions storing charges from adjacent phase detecting pixels covered with micro lenses.
- Outputting a signal based on charges accumulated in the floating diffusions.
- Row driver applying boosting control signal to transfer charges from second to first floating diffusion after signal output.
Potential Applications
This technology could be used in:
- Digital cameras
- Surveillance systems
- Medical imaging devices
Problems Solved
- Improved charge transfer efficiency
- Enhanced image sensor performance
- Reduction of noise in image capture
Benefits
- Higher quality image capture
- Increased sensitivity
- Enhanced low-light performance
Potential Commercial Applications
Optimizing Image Sensor Charge Transfer for Enhanced Performance
Possible Prior Art
Prior art related to charge transfer efficiency in image sensors may exist, but specific examples are not provided in the abstract.
Unanswered Questions

Original Abstract Submitted
an example embodiment provides an image sensor including: a pixel array including a first floating diffusion and a second floating diffusion, the first floating diffusion and the second floating diffusion configured to store charges generated by a first phase detecting pixel and a second phase detecting pixel adjacent to each other in a first direction and covered with one micro lens, and the pixel array is configured to output a first signal based on a charge that is generated by the first phase detecting pixel to be accumulated in the first floating diffusion and the second floating diffusion; and a row driver configured to apply a boosting control signal to the second floating diffusion to transfer charges stored in the second floating diffusion to the first floating diffusion, after the pixel array outputs the first signal.
