Abstract: A method by which an electronic device performs a DNN operation includes performing a first modified operation including extending a channel of an output of a first layer with respect to a feature map input into the first layer, the first layer being one of a plurality of layers of a DNN, wherein the first modified operation includes a space-to-depth transformation operation, performing a neural network operation corresponding to layers between the first layer and a second layer as a channel-extended neural network operation, wherein the second layer is a layer of the plurality of layers of the DNN after the first layer, performing a second modified operation including reducing a channel of an output of the second layer with respect to a channel-extended feature map input into the second layer, wherein the second modified operation includes a depth-to-space transformation operation, and outputting a result of the DNN operation.

Abstract: An image processing device, which includes processing circuitry configured to cause the image processing device to first detect a first bad pixel based on first image data, correct the first bad pixel based on first values of first peripheral pixels in response to the first detection to obtain a first correction result, the first peripheral pixels being peripheral to the first bad pixel, second detect the first bad pixel and a second bad pixel based on the first image data, the second bad pixel being adjacent to the first bad pixel, correct the second bad pixel based on second values of second peripheral pixels to obtain a second correction result, the second peripheral pixels being peripheral to the second bad pixel, and correct the first bad pixel by using the first correction result stored in a buffer in response to the second detection.
