摘要： The present invention relates to a signal processing apparatus and a method, a recording medium, and a program, in which portions except an edge can be smoothed while the edge whose change in pixel value is steep is held correctly. A pixel of attention is determined in step S11, and a neighboring pixel is determined in step S12. In step S13, a difference in pixel values between the pixel of attention and each neighboring pixel is calculated. In step S14, according to a relationship in size between the difference and a threshold value ε., flags are raised for the neighboring pixel and a neighboring pixel which are symmetrical. Furthermore, a flag is also raised for a neighboring pixel away from, in view of the pixel of attention, the symmetrical neighboring pixel for which the flag is raised. In step S15, 7-pixel taps centered around the pixel of attention are averaged by weight. However, with respect to the neighboring pixel for which the flag is raised, the pixel value is replaced by that of the pixel of attention C, and is calculated. The present invention can be applied to a video camera, a television receiver, etc.

摘要： An n-filter according to the present invention includes a nonlinear filter, a pattern detector, and a switch. The nonlinear filter maintains a steep edge whose size is larger than a predetermined threshold in fluctuations of pixels constituting an input image signal and, at the same time, smoothes a non-edge portion that does not include the edge. The pattern detector detects a fine edge in the fluctuations of the pixels constituting the input image signal and notifies the switch that the fine edge exists. The switch outputs the input image signal or an image signal output from the nonlinear filter to the subsequent stage in accordance with the notification from the pattern detector.

摘要： A histogram section determines as a motion vector at a pixel of interest the candidate motion vector with highest frequency from among a candidate motion vector at the pixel of interest and candidate motion vectors at pixels neighboring the pixel of interest supplied by a template matching section, and supplies it to a motion-vector correcting section. The motion-vector correction section evaluates the confidence level of the motion vector supplied by the histogram section based on the luminance gradient around the pixel of interest detected by a luminance-gradient detecting section and a control signal indicating whether correction should be carried out supplied by the template matching section. If it is determined that the confidence level of the motion vector is low, the motion vector is corrected.
