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: 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: A processor-implemented method with super resolution includes: determining a direction type of an input image based on a gradient of the input image; acquiring a first intermediate image that is a super-resolution image corresponding to the input image based on a residual look-up table (LUT) corresponding to a kernel set mapped to the determined direction type; determining a LUT strength map of the input image based on the gradient of the input image and a preset tuning parameter; and generating an output image that is a super-resolution image of the input image based on the LUT strength map and the first intermediate image.
