Introduction
Tongtong Yu is an accomplished inventor based in Fremont, CA. He has made significant contributions to the field of image sensor technology, holding 2 patents that showcase his innovative approach to imaging systems.
Latest Patents
One of his latest patents is for an "Image sensor with in-pixel background subtraction and motion detection." This imaging system features a pixel array that generates image charge voltage signals in response to incident light. The system includes an infrared illumination source that is deactivated during the capture of the first image and activated for the second image. Additionally, it employs an array of sample and hold circuits to store the image charge voltage signals, allowing for the identification of objects in the foreground of an external scene.
Another notable patent is the "Image sensor with voltage buffer for self-test." This invention includes test voltage sample and hold circuitry within the readout circuitry of an image sensor. The circuitry samples a voltage based on a ramp voltage shared by the ADC comparators. The sampled voltage is held by a capacitor during the readout of one row and accessed during the next row for testing purposes. This self-test mechanism ensures the reliability of the image sensor by comparing measured data with expected data.
