With three patents to his name, Tanno focuses on enhancing image quality and efficiency in data coding methods. His work is crucial in an era where digital image processing is becoming increasingly important.

Latest Patents

Tanno's latest patents reflect his expertise and innovative approach to image coding. The first patent, titled "Image coding device and method of image coding," introduces an input image controller that reduces the frame rate of a motion image signal as a preprocessing step. This system provides process information regarding the skipped frames to the image coder, utilizing the MPEG-2 method for coding the motion image signal. The result is a data output that conforms to the MPEG-2 standards while including essential overhead information.

The second patent, "Picture coding apparatus and picture coding method," innovates further by employing a picture analyzer to detect coding difficulty information from the source picture data. A picture converter is then utilized to alter the format of this data through spatial and/or temporal conversion. Furthermore, a coding unit codes the converted picture data, with a preprocess controller managing the picture converter based on the detected coding difficulty. This advanced process culminates in encoded pictures that boast exceptional image quality, minimizing block distortion and optimizing quantization steps, even at low bit rates.
