Latest Patents
One of his latest patents is a picture signal processing apparatus. This innovative device features a matrix switcher that selectively seizes multiple compressed pictures and converts P-frames in a Group of Pictures (GOP) into I-frames while modifying the prediction data of B-frames in the GOP. The apparatus includes a decoder that expands the compressed pictures back into their original form. An input buffer memory converts the picture signals into component signals while adjusting the transfer rate. The picture processing unit performs various operations on the picture signals, and an encoder compresses the processed signals for transmission. The output buffer memory adjusts the transfer rate of the sent-out data, ensuring smooth switching of compressed pictures processed by inter-frame compression. This technology allows for extensive picture processing capabilities, accommodating a wide range of formats from still images to moving pictures.
