Abstract: An image processing apparatus includes; an image sensor including pixels that generate first image data, and an image processing system. The image processing system includes; a neural network processor that performs a cluster-level bad pixel correction operation on the first image data based on first coordinate information associated with first-type bad pixel clusters to generate second image data, and a main processor that performs a post-processing operation on the second image data to generate third image data.

Abstract: An electronic device includes an image sensor that generates first image data upon receiving external light, generates second image data based on the first image data, and outputs the first image data and the second image data, and an application processor that increases resolution of at least a region of an image that corresponds to the first image data using a machine learning algorithm and outputs third image data that includes at least a portion of the first image data with increased resolution and at least a portion of the second image data.

Abstract: An image signal processor configured to receive a digital signal from an image sensor includes a saturation detecting unit configured to classify each of a plurality of pixels, corresponding to the digital signal, as either a saturated pixel or a non-saturated pixel and to select a compensable pixel among the saturated pixels, a color processing unit configured to estimate channel values for each color for each of the plurality of pixels corresponding to the digital signal and to perform a correlation calculation between the channel values for each color, and a saturation compensation unit configured to select at least one color-transfer pixel, among the non-saturated pixels, based on the correlation calculation value between the channel values for each color and to perform a compensation operation on the compensable pixel based on the at least one color-transfer pixel. The image signal processor may recover information, lost due to saturation, through a color-transfer method using a correlation between colors. Accordingly, a dynamic range may be extended.

Abstract: An image sensor includes a pixel array including a plurality of pixels arranged in a row direction and a column direction and a read-out circuit that generates image data and phase data based on a sensing signal received from the pixel array. The image sensor is configured the resolution of the phase data output by read-out circuit depending on target area information for the pixel array, the target area information received from outside of the image sensor.
