Patent
Encoding apparatus and method and storage medium
TL;DR: In this article, an encoding method comprises the steps of receiving image data for each predetermined unit, separately employing K types of k parameters to perform Golomb-Rice coding for the image data, and generating k types of GCR coded data, holding the K types obtained at the generation step, and selecting one of the k parameters for each specified unit, and employing the selected k parameter to select and output the coded data that are being held.
Patent
Special effect apparatus with power control
TL;DR: In this paper, a special effect device consisting of a first signal source, a second signal source and a subtracting circuit, coefficient multiplying circuit, adding circuit, switch circuit and control circuit is presented.
Patent
Decoding apparatus and method
TL;DR: In this article, the authors proposed a decoding scheme for employing peripheral pixels to perform fast decoding, and in particular to perform decoding while taking into account the timing of the values of peripheral pixels are obtained.
Patent

Tadayoshi Nakayama,Naoki Ito +1 more
TL;DR: In this article, an encoder and a re-encoder are used to encode an image while continuously inputting the image with a relatively simple configuration, where the encoder discards the data in the first memory and instructs the encoded data to increase the quantization step and continue encoding.
Patent
Image signal reproducing apparatus
TL;DR: An image signal reproducing apparatus for reproducing image signals from a record bearing medium on which image signals consisting of a plurality of groups of image planes are recorded is arranged to reproduce the image signals recorded on the recordbearing medium; to extract, from among the reproduced image signals, representing image signals corresponding to representing image planes; and to produce the representing image signal together with the position information signals which respectively correspond to the corresponding image signals as mentioned in this paper.
