Image data storage method
View Patent ↗If a user wants to store an image acquired from a site and it is determined that the data size of the image acquired from the site is larger than a designated storage frame in a memory region, then it is determined whether or not the number of colors in the pallet of the acquired image data can be reduced. Next, if the number of pallet colors can be reduced, the number of pallet colors is reduced to thereby compress the pallet and the image data is updated based on the compressed pallet. On the other hand, if it is determined that the number of pallet colors cannot be reduced, a control section determines that the image data cannot be registered or stored and abandons the data and a display section displays storage error.
1. An image data storage method using a portable terminal including display means for displaying an image and a memory storing image data, said memory including a plurality of image data storage frames each having an equal storage capacity, which comprises the steps of:
determining whether the image data acquired by said portable terminal is larger than each of said storage frames;
determining whether the number of pallet colors of said image data is larger than a predetermined threshold value if said image data is larger than said storage frame;
reducing the number of pallet colors of said image data if the number of pallet colors of said image data is larger than the predetermined threshold value; and
updating said image data based on said color-reduced pallets,
wherein if a size of said updated image data is equal to or smaller than said storage capacity, the updated image data is registered or stored in said storage frames.
2. The image data storage method according to claim 1 using a portable terminal including display means for displaying an image and a memory storing image data, said memory including a plurality of image data storage frames each having an equal storage capacity, which comprises the steps of:
determining whether the number of vertical and horizontal dots of said image data is larger than a predetermined image size threshold value if the number of pallet colors of the image data acquired by said portable terminal is equal to or smaller than a predetermined threshold value; and
changing the number of the vertical and horizontal dots of said image data and updating said image data if the number of the vertical and horizontal dots of said image data is larger than the predetermined image size threshold value,
wherein if said image data updated by changing the number of the vertical and horizontal dots of said image data is equal to or smaller than said storage capacity, the updated image data is stored in said storage frames.
3. An image data storage method using a portable terminal including display means for displaying an image and a memory including a storage region storing image data and a temporary region temporarily storing the image data, which comprises the steps of:
determining whether the image data acquired by said portable terminal is larger than a capacity of a vacant region of said storage region;
determining whether the number of pallet colors of said image data is larger than a predetermined threshold value if the image data acquired by said portable terminal is larger than a capacity of a vacant region of said storage region;
storing the image data acquired by said portable terminal in said temporary region if the number of pallet colors of said image data is equal to or smaller than the predetermined threshold value; and
reducing the number of pallet colors of other image data stored in said storage region, and increasing the storage capacity of said vacant region,
wherein if the image data stored in said temporary region becomes equal to or smaller than the capacity of said vacant region, the image data is registered or stored in said vacant region of said storage region.
4. The image data storage method according to claim 3 , wherein if the image data stored in said temporary region is larger than an entire storage capacity of said storage region, the image data is abandoned.
5. The image data storage method according to claim 2 , wherein said predetermined image size threshold value is equal to the number of vertical and horizontal dots of said display means.
6. The image data storage method according to 1 , characterized in that said predetermined color number threshold value is equal to the number of pallet colors of said display means.
7. The image data storage method according to 3 , characterized in that said predetermined color number threshold value is equal to the number of pallet colors of said display means.
