While the benefits of correcting black spot generation values are mentioned, the specific improvement in image quality is not detailed in the abstract.
Original Abstract Submitted
an image sensor includes a pixel array including a plurality of pixels operating in a plurality of modes, a readout circuit configured to receive a pixel signal corresponding to each of the plurality of modes from each of the pixels and generate a pixel value that is a digital signal from the pixel signal, and a signal processor configured to determine whether a target pixel value is a black spot generation value for each of the pixels based on at least one of comparison pixel values of each comparison mode among a plurality of comparison modes having a smaller output gain than a target mode corresponding to the target pixel value, and correct the target pixel value when the target pixel value is the black spot generation value.
