Thumbnail Size Adjustment for Content Identifiability

The patent applies local quality by allowing each thumbnail to have a different size based on its specific content characteristics. The determining unit evaluates each thumbnail individually and sets appropriate sizes, so that thumbnails containing important or detailed information are displayed larger while less critical thumbnails can be smaller. This resolves the contradiction by making the display quality non-uniform across thumbnails while maintaining overall screen efficiency.

The patent changes the size parameter of thumbnails dynamically based on content analysis. The determining unit adjusts the display size parameter for each thumbnail according to its information density and importance, rather than applying a uniform size reduction. This allows the system to maintain information identifiability for critical thumbnails while fitting more thumbnails on the screen overall.

By applying local quality, the patent ensures that thumbnails requiring higher selection accuracy (those with important information) are displayed with larger sizes, making them easier to identify and select. Less critical thumbnails can be displayed smaller, increasing overall display density. This differential approach maintains ease of operation for important selections while improving overall browsing productivity.

The determining unit performs preliminary analysis of each thumbnail's content characteristics before display, pre-determining the appropriate size for each thumbnail based on its information importance. This preliminary action ensures that when users browse thumbnails, the sizing optimization is already in place, facilitating easier identification and selection without requiring additional user effort during the selection process.
