Latest Patents

Ishii's latest patents include an image processing method, image processing apparatus, and image pickup apparatus. This innovation features a correlation evaluation unit that assesses the correction between a specific region in a targeted picture and a corresponding region in a different picture over time. The quantization control unit adaptively manages the quantization processing for the targeted region based on the evaluation from the correlation unit. For instance, if the correlation is found to be weaker than a predetermined threshold, the quantization control unit increases the quantization step for that region.

Another notable patent is an image display method, image coding apparatus, and image decoding apparatus. This apparatus addresses various demands for image distribution from both providers and users. It includes a coding block that encodes predetermined image data. A separation unit divides the coded image data into basic data for visible image reproduction and complementary data for enhancing the basic data. Additionally, an adding unit incorporates independent copyright control information into either the basic or complementary data.
