IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240259715 titled 'IMAGE SENSOR
The abstract describes an image sensor that includes a pixel array, a ramp signal generator, a signal selector, and a comparison circuit.
- Pixel array with multiple pixels
- Ramp signal generator produces a signal with a constant slope
- Signal selector outputs ramp signal, pixel signal, or test signal from the pixel array
- Comparison circuit compares ramp signal with test signal during one period and pixel signal with ramp signal during another period
Potential Applications: - Digital cameras - Surveillance systems - Medical imaging devices
Problems Solved: - Ensures accurate and consistent image capture - Improves image quality and resolution
Benefits: - Enhanced image sensor performance - Increased reliability in image processing - Improved overall image quality
Commercial Applications: Title: "Advanced Image Sensor Technology for Enhanced Imaging Devices" This technology can be used in various commercial applications such as digital cameras, surveillance systems, and medical imaging devices. The market implications include improved image quality, enhanced performance, and increased reliability in image processing.
Questions about Image Sensor Technology: 1. How does the ramp signal generator contribute to the performance of the image sensor? The ramp signal generator ensures a consistent and accurate signal for comparison with the pixel and test signals, leading to improved image quality and resolution.
2. What are the potential commercial applications of this advanced image sensor technology? This technology can be utilized in digital cameras, surveillance systems, and medical imaging devices to enhance image quality and overall performance.
Original Abstract Submitted
an image sensor is provided. the image sensor according to an example embodiment includes a pixel array including a plurality of pixels, a ramp signal generator configured to generate a ramp signal that increases or decreases with a constant slope, a signal selector configured to output the ramp signal and one of a pixel signal and a test signal output from the pixel array, and a comparison circuit configured to receive the ramp signal and the test signal from the signal selector during a first period, output a first comparison result of the ramp signal and the test signal, receive the pixel signal and the ramp signal from the signal selector during a second period after the first period, and output a second comparison result of the pixel signal and the ramp signal.
