Abstract: Provided are image signal processing apparatuses and methods for operating the same. In an embodiment, the image signal processing apparatus is configured to receive, from an image sensor device, an input image. The apparatus is further configured to perform a binning and crop operation on the input image to generate a first image. The apparatus is further configured to perform a Bayer domain processing on the first image to generate a second image. The apparatus is further configured to perform RGB domain processing on the second image to generate a third image. The apparatus is further configured to perform YUV domain processing on the third image to generate an output image. The YUV domain processing comprises at least one of a spatial de-noising operation, a temporal de-noising operation, a motion compensation operation, a tone mapping operation, a detail enhance operation, and a sharpening operation.

Abstract: The present disclosure relates to an image processing device to which contrast improvement effect may be applied, an image processing system, and a method of operating the same. An example method of operating an image processing device includes receiving an image including a plurality of pixels, splitting the image into a plurality of first regions, calculating a histogram for a second region that is greater than a first region of the plurality of first regions, generating a contrast conversion function based on the histogram for each of the plurality of first regions, and converting contrast of a current pixel among the plurality of pixels based on M×M first regions among the plurality of first regions adjacent to the current pixel. M is a natural number greater than or equal to 2.

Abstract: A method and an apparatus for concealing an error of an apparatus for receiving an audio frame in a communication system are provided. The includes determining whether the error occurs in a current audio frame that is received from a transmitter, determining whether the audio frame includes a signal that corresponds to a preset specific frequency when the error occurs, setting a gain of the signal that corresponds to the specific frequency to be lower than a preset limit value if the audio frame includes the signal, and concealing the error of the current audio frame based on a previous audio frame of the audio frame in which the error occurs and the gain of the signal that corresponds to the set specific frequency.

Abstract: A method of reducing noise in an input image by setting, as a local window among color pixels included in the input image, a target pixel and neighboring pixels adjacent to the target pixel, determining color pixel values for the target pixel and each of the neighboring pixels included in the local window, generating local color average values are generated by averaging, color by color, the color pixel values, generating offset color pixel values by converting the color pixel values of the target pixel and the neighboring pixels based on the local color average values, and generating a compensated color pixel value of the target pixel by adjusting the color pixel value of the target pixel based on the offset color pixel values.
