Latest Patents
Ozeki's latest patents include a "Video encoder using global motion estimation and polygonal patch motion." This invention is designed to ensure high coding efficiency even at low bit rates. It features a moving object analyzer that extracts moving parts from input picture signals, analyzes their motion, and outputs a residual signal relative to a reconstruction image along with motion parameters. Additionally, the apparatus includes a residual coding device for coding the residual signal, a reconstruction device for reconstructing images using the motion parameters, and a variable length coding device for the motion parameters and residual coded information.
Another notable patent is the "Image transmission apparatus." This invention divides an input image signal into blocks of 8 x 8 pixels, applies a cosine transform, and converts it to a signal in the spatial frequency region. The data undergoes subtraction with respect to four types of data, allowing for the selection of the minimum difference data for quantization and transmission. This method ensures high transmission efficiency regardless of the degree of image change.
