Latest Patents

Kondo's latest patents include an image processing device and a moving image transmission method. This innovative device performs scaling and applies super-resolution based on the complexity of the image. The compression side features a complexity calculation unit that assesses the transmission image complexity, which indicates the intricacy of the input image. This information is multiplexed and outputted to an encoded stream. Additionally, a control unit adjusts 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, a complexity calculation unit evaluates the decoded image complexity, which reflects the complexity of the decoded and expanded image. A complexity comparison unit then compares the transmission and decoded image complexities, outputting the difference or ratio. Based on this output, a parameter calculation unit optimizes the scaling coefficient of an image enlargement unit and the folding frequency of a super-resolution processing unit.

Another notable patent is an image encoding device and method that achieves high efficiency through quantization of each sub-block according to visual characteristics. The input image is divided into macro-blocks of a specified size, which are further divided into sub-blocks. Each sub-block is encoded using the same or different quantization parameters, allowing for highly efficient image encoding and decoding.
