Reproducing apparatus

Abstract

A reproducing apparatus includes: a reproducing portion for reproducing, from a recording medium, moving image data including plural frames whose information amount has been compressed by intraframe encoding; a memory for storing the moving image data reproduced by the reproducing portion; a decoding portion for reading out the frames of the moving image data stored in the memory and decoding the read-out data, the decoding portion reading out the moving image data in succession starting from an upper end of a screen for each frame to decode the read-out moving image data; an instruction portion for instructing enlargement of the moving image data; an enlarging area setting portion for setting, for each frame of the moving image data, a partial area on which enlarging processing is to be performed; a control portion for controlling the decoding portion in accordance with the enlarging instruction, the control portion stopping reading out the one frame of moving image data from the memory, which is performed by the decoding portion, in case that moving image data of the partial area in the one frame of the moving image data is decoded; and an output portion for modifying, in accordance with the number of pixels of the display device, the moving image data of the partial area decoded, and outputting the modified image data to the display device.

What is claimed is: 
     
         1 . A reproducing apparatus comprising:
 reproducing means for reproducing, from a recording medium, moving image data including plural frames whose information amount has been compressed by intraframe encoding;   a memory for storing the moving image data reproduced by the reproducing means;   decoding means for reading out the frames of the moving image data from the memory and decoding the read data, the decoding means reading out the moving image data in succession starting from an upper end of a screen for each frame to decode the read-out moving image data;   instruction means for instructing enlargement of the moving image data;   enlarging area setting means for setting, for each frame of the moving image data, a partial area on which enlarging processing is to be performed;   control means for controlling the decoding means in accordance with the enlarging instruction given by the instruction means, the control means stopping reading out the one frame of moving image data from the memory, which is performed by the decoding means, in case that moving image data of the partial area in the one frame of the moving image data is decoded; and   output means for modifying, in accordance with the number of pixels of the display device, the moving image data of the partial area decoded by the decoding means, and outputting the modified image data to the display device.
