Filed: 2002-03-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide a simple moving picture encoder capable of automatically selecting encoding resolution so as to provide an output of an encoded image with high image quality.  <P>SOLUTION: The variance of pixel values in each block in a moving picture frame is obtained, and when the average value of frames of the variance exceeds a prescribed value, an upper limit frequency of a transmitted orthogonal transform coefficient is halved. In the case of a complicated input image having a large variance, decreasing the upper limit of the frequency of the transmitted orthogonal transform coefficient decreases the resolution and suppresses production of encoding noise. Conversely, in the case of a simple video input with a small variance, the upper limit of the frequency of the transmitted orthogonal transform coefficient it not limited and encoding with high resolution is performed. Revising the upper limit frequency for the transmitted orthogonal transform coefficient depending on a result of discriminating the property of the input image according to the pixel value variance of the input image can enhance the image quality even with a limited frequency band.  <P>COPYRIGHT: (C)2003,JPO
