    摘要： An image sensor comprises an arrangement of pixels, the pixels including an acquisition circuit each, the acquisition circuit including: a sensor circuit configured to generate a sensor signal (VLOG) depending on a light signal illuminating a photosensor of the pixel; a storage circuit configured to store during a storage interval a stored signal (VSTORE) proportional to the sensor signal (VLOG); and a comparator circuit configured to generate after the refresh interval a comparator signal (VCOMP) depending on the sensor signal (VLOG) and the stored signal (VSTORE). A method of operating an image sensor comprises steps of generating a sensor signal (VLOG) depending on a light signal illuminating a photosensor of the pixel, storing during a storage interval a stored signal (VSTORE) proportional to the sensor signal (VLOG) and generating after the refresh interval a comparator signal (VCOMP) depending on the sensor signal (VLOG) and the stored signal (VSTORE).

    摘要： An image sensor device may include a pixel sensor array and a black level correction (BLC) region. The BLC region may include a sensing region in a substrate and a light-blocking layer above the sensing region. An anti-reflection array may be formed in the light-blocking layer. The anti-reflection array includes holes, trenches, and/or other structural features such that the light-blocking layer includes two or more areas in which the top surface of the light-blocking layer is at different heights in the image sensor device. The different heights of the top surface of the light-blocking layer reduce the likelihood of light being reflected off of the light-blocking layer and toward the pixel sensor array. The anti-reflection array may reduce the likelihood of occurrence of flares or hot spots in images generated by the image sensor device, which may increase the image quality of the images generated by the image sensor device.

    摘要： There is provided an image sensor employing an avalanche diode. The image sensor includes a plurality of pixel circuits arranged in a matrix, a plurality of pulling circuits and a global current source circuit. Each of the plurality of pixel circuits includes a single photon avalanche diode (SPAD) and a floating diffusion. Each of the plurality of pulling circuits is arranged corresponding to one pixel circuit column. The global current source circuit is used to form a current mirror with each of the plurality of pulling circuits. The floating diffusion is used to record a voltage of one photon event detected by the SPAD in an exposure period.
