Latest Patents

Kadoto's latest patents include an image processing device and a moving image transmission method. The image processing device performs scaling and applies super-resolution based on the complexity of the image. It features a complexity calculation unit that calculates the transmission image complexity, multiplexes it, and outputs it to an encoded stream. Additionally, a control unit configures the cutoff frequency of a low pass filter and the scaling coefficient of an image reduction unit according to the transmission image complexity. On the decompression side, another complexity calculation unit assesses the decoded image complexity, while a complexity comparison unit compares the transmission and decoded image complexities to optimize the scaling coefficient of an image enlargement unit.

The motion picture encoding apparatus addresses the suppression of prediction error accumulating in intra prediction. This apparatus performs encoding processing for each pixel block using a motion picture encoding method that includes intra prediction processing. It generates a prediction image using the correlation of surrounding pixels. The apparatus also incorporates a method for generating a quasi-prediction image from an input image, emphasizing the reference pixel's error to minimize the propagation of errors to subsequent blocks.
