DECODING APPARATUS, DECODING METHOD, AND NON-TRANSITORY RECORDING MEDIUM

摘要

When necessary process times in a reception apparatus for a determination on a change area, a determination on the color of the change area, and a decoding of bit data stream exceed a predetermined time from a frame acquiring timing, and a process delay would occur, an image generator acquires a frame. In addition, a decoder temporarily stores the frame in a memory, and thereafter at a predetermined timing performs the determination on the change area, the determination on the color of the change area, and the decoding of the bit data stream.

1. A decoding apparatus comprising:
an acquiring unit configured to continuously acquire images that contain visible lights changing in time-series; a first decoding unit configured to sequentially decode information from the visible lights contained in the images continuously acquired by the acquiring unit; a record controlling unit configured to continuously record, in a memory, the images acquired by the acquiring unit based on an acquiring speed of the acquiring unit or a process speed by the first decoding unit; and a second decoding unit configured to sequentially decode the information from the visible lights contained in the images recorded in the memory.
