  • Publication number: 20240332325
    Abstract: In some implementations, a pixel array may include a near infrared (NIR) cut filter layer for visible light pixel sensors of the pixel array. The NIR cut filter layer is included in the pixel array to absorb or reflect NIR light for the visible light pixel sensors to reduce the amount of NIR light absorbed by the visible light pixel sensors. This increases the accuracy of the color information provided by the visible light pixel sensors, which can be used to produce more accurate images. In some implementations, the visible light pixel sensors and/or NIR pixel sensors may include high absorption regions to adjust the orientation of the angle of refraction for the visible light pixel sensors and/or the NIR pixel sensors, which may increase the quantum efficiency of the visible light pixel sensors and/or the NIR pixel sensors.

  • Publication number: 20240323555
    Abstract: 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.

  • Patent number: 11985438
    Abstract: A pixel array includes a plurality of dark pixel sensors configured to generate dark current calibration information for a plurality of visible light pixel sensors included in the pixel array.
