動画処理装置
Document Type and Number:
Japanese Patent JP4610523
Kind Code:
B2
Abstract:
A motion picture processing device has: an input circuit having a buffer memory, an image data taking-in section and a bus interface; a motion estimation circuit; an encoding circuit; and a failure control circuit having a counter and an enabling signal outputting section. When an enabling signal is supplied, the image data taking-in section takes-in image data, and when image data of one screen is stored in the buffer memory, the image data taking-in section outputs a valid signal. The encoding circuit compresses and encodes image data, and, when the encoding circuit finishes external output of an output signal, the encoding circuit outputs an end signal. The counter increments a count value due to the valid signal, and decrements the count value due to the end signal. When the count value reaches a number of regions of the memory circuit, the failure control circuit stops output of the enabling signal.
