IMAGE SENSOR, METHOD OF OPERATING THE IMAGE SENSOR, AND IMAGE PROCESSING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240121526 titled 'IMAGE SENSOR, METHOD OF OPERATING THE IMAGE SENSOR, AND IMAGE PROCESSING DEVICE
Simplified Explanation
The patent application describes an image sensor that can capture images using different exposure times for each pixel, allowing for improved image quality and dynamic range.
- Pixel array generates analog signals based on charge accumulation during different exposure times.
- Analog-to-digital conversion circuit converts analog signals to digital signals using different ramp signals.
- Image signal processor generates image data based on the digital signals.
- Different ramp signals used for each exposure time to improve image quality.

Original Abstract Submitted
an image sensor includes a pixel array, an analog-to-digital conversion circuit, and an image signal processor. a pixel of the pixel array generates a first analog signal based on a quantity of charge accumulated during a first exposure time and generate a second analog signal based on a quantity of charge accumulated during a shorter second exposure time. the analog-to-digital conversion circuit may generate a first digital signal based on the first analog signal and a first ramp signal and may generate a second digital signal based on the second analog signal and a second ramp signal. the image signal processor may generate image data based on the first and second digital signals. the first ramp signal may be different from the second ramp signal in terms of at least one of a ramping time or a ramping start voltage level.
