Abstract
A process and apparatus for displaying and recording image data can be smoothly performed in characteristic methods by computing a quantization parameter for use in compression of image data, obtaining a difference in the amount of processes between the display of image data and the recording of image data, and managing memory of temporarily stored image data for regeneration of recorded image data.
Claims9
An image regeneration apparatus, which regenerates image data of at least one image data group of image data including representative image data and plural pieces of image data associated with the representative image data or a single piece of image data, provided by a record medium built in the apparatus or a record medium mounted on the apparatus, comprising:
- a temporary storage unit temporarily storing at least one piece of representative image data in the representative image data and the image data group, or the single piece of image data;
- an image selection unit selecting from said temporary storage unit a piece of image data as an image to be displayed from representative image data or a single piece of image data;
- a reproduction designation unit designating for regeneration of an image data group associated with selected representative image data when the representative image data is selected by the image selection unit;
- and
- a storage control unit controlling the image data of the image data group to be temporarily stored in the temporary storage unit before regeneration of the image data group by the regeneration designation.
An image regeneration apparatus which displays at least representative image data or any of a single piece of image data, in an image data group including the representative image data and plural pieces of image data related to the representative image data, or in a single piece of image data, comprising:
- a temporary storage unit temporarily storing at least the representative image data or any of a single piece of image data in the representative image data, the image data group, or the single piece of image data;
- an image selection unit selecting a piece of image data as an image to be displayed from the temporarily stored representative image data or a piece of image data;
- and
- a storage control unit for controlling storage using an image data group related to the selected image data or related image data by making a predetermined determination with the selected image data for a specified storage area by specifying a storage area having a predetermined priority from a storage area of the temporary storage unit depending on whether the selected image data is representative image data or a piece of image data.
