Latest Patents

Kunimi's latest patents include innovative designs for solid-state imaging devices. One patent describes an imaging sensor that features a pixel array with both an active imaging portion and a shielded portion. The active imaging portion generates an image signal based on light that strikes the pixel array, while the shielded portion is protected from light, providing a dark current signal. This imaging sensor incorporates a black-level adjustment circuit that compensates for variations in black-level values of the imaging signal. The circuit includes an average value calculator that computes average signal values for various shielded regions, ensuring accurate image capture.

Another patent focuses on a solid-state imaging device that establishes a black level reference during image capture. This device consists of an effective pixel portion with active pixels and a light-shielded pixel portion. It features an ADC circuit that performs analog-to-digital conversion based on a reference voltage, which is adjusted by a clamping voltage. The AD clamping circuit calculates the clamping voltage necessary for achieving a target black level, enhancing the quality of the captured images.
