发明名称 ENCODING UNIT AND DECODING UNIT
摘要 PROBLEM TO BE SOLVED: To provide an encoding unit and a decoding unit which are capable of compressing (encoding) and expanding (decoding) image signals outputted from a television camera of an IP type. SOLUTION: An inter-frame encoding unit 11 carries out an encoding operation as to input integral photography signals P1, using a correlation between image signals by the use of the image signals of a current display frame and the image signals of a preceding display frame prior to the current display frame. An intra-frame encoding unit 12 carries out an encoding operation by the use of image signals within the closed region in the current display frame. An inter-element image encoding unit 13 carries out an encoding operation, using a plurality of image signals corresponding to a plurality of element images by the use of a correlation between the image signals. An encoding selection unit 14 selects the most encoding efficient encoding output out of those of the inter-frame encoding unit 11, the intra-frame encoding unit 12, and the inter- element image encoding unit 13; and outputs it as an encoding output C1.
