DECODING DEVICE, ELECTRONIC DEVICE, AND DECODING METHOD

摘要

A decoding section 111 decodes inputted coded data to image data and outputs it to an image data writing section 112 whenever necessary. The decoding section 111 outputs a decode completion notice signal to an image data reading section 114 and control signal generating section 115 every time when outputting a predetermined amount of image data (for example, an amount corresponding to one frame). The image data writing section 112 writes image data to the storing section 113 whenever necessary. An image data reading section 114 operates intermittently with timing when the decode completion notice signal is input thereto, and reads a predetermined amount of image data from the storage section 113. The control signal generating section 115 generates a control signal 206 that instructs a new portion in image data decoded by decoding means. Then, the control signal generating section 115 outputs the control signal 206 from the image data output section 116 with timing when the image data reading section 114 inputs the decode completion notice signal 204. This makes it possible to intermittently transfer image data to a display device 121 from a decoding apparatus 101 without providing an auxiliary circuit to the outer section and to miniaturize a mobile terminal device for image communication, and to improve a reduction in power consumption, resulting in a reduction of a processing load required to monitor MPU.
