IMAGE SENSOR DEVICE AND OPERATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240340549 titled 'IMAGE SENSOR DEVICE AND OPERATION METHOD THEREOF
The abstract describes an image sensor device with a pixel that outputs different signals during different time periods, along with a clamp circuit that operates at a lower voltage than the pixel.
- Pixel outputs first and second signals to a column line during different time periods
- Clamp circuit outputs a signal to the column line during the first time period
- Voltage of the column line is determined based on the pixel signal and clamp signal
- Pixel operates at a higher power supply voltage than the clamp circuit
Potential Applications: - Digital cameras - Surveillance systems - Medical imaging devices
Problems Solved: - Ensures accurate voltage levels for pixel operation - Prevents signal distortion during different time periods
Benefits: - Improved image quality - Enhanced signal accuracy - Efficient power usage
Commercial Applications: Title: "Advanced Image Sensor Technology for High-Quality Imaging" This technology can be used in various commercial applications such as digital cameras, surveillance systems, and medical imaging devices. It offers improved image quality, signal accuracy, and efficient power usage, making it a valuable innovation for the imaging industry.
Questions about Image Sensor Technology: 1. How does the clamp circuit ensure accurate voltage levels for pixel operation? The clamp circuit outputs a signal to the column line during the first time period, which helps determine the voltage of the column line based on the pixel signal and clamp signal.
2. What are the potential applications of this image sensor technology? This technology can be used in digital cameras, surveillance systems, and medical imaging devices to improve image quality and signal accuracy.
Original Abstract Submitted
disclosed is an image sensor device which includes a pixel that outputs a first pixel signal to a first column line during a first time period and outputs a second pixel signal to the first column line during a second time period, and a clamp circuit that outputs a first clamp signal to the first column line during the first time period. during the first time period, a voltage of the first column line is determined based on the first pixel signal and the first clamp signal. the pixel operates based on a first power supply voltage, and the clamp circuit operates based on a second power supply voltage lower than the first power supply voltage.
