Abstract
An analyzer of a display control apparatus analyzes image characteristics of an image that has been pixel-converted by a pixel converter. A number-of-pixels determining unit compares the analysis result obtained by the analyzer with predetermined deterioration determination thresholds and determines the number of display pixels that is optimal for content. A pixel converter converts the number of pixels of the content into the determined optimal number of display pixels.
Claims16
A display control apparatus for displaying on a display unit an enlarged image that represents an enlargement of an image of content, the display unit having a number of pixels greater than a number of pixels of the content, the display control apparatus comprising:
- an analyzer configured to analyze an image characteristic of the enlarged image;
- a number-of-pixels determining unit configured to determine a number of display pixels of the enlarged image so that the image characteristic analyzed by the analyzer satisfies a predetermined determination criterion;
- and
- a pixel converter configured to perform pixel conversion of the image of the content to generate the enlarged image, the enlarged image having the number of display pixels determined by the number-of-pixels determining unit, and to output the enlarged image to the display unit.
A display control apparatus for displaying on a display unit an enlarged image that represents an enlargement of an image of content, the display unit having a number of pixels greater than a number of pixels of the content, the display control apparatus comprising:
- an analyzer configured to analyze an image characteristic of the content;
- a number-of-pixels determining unit configured to determine a number of display pixels of the enlarged image so that an image characteristic of the enlarged image satisfies a predetermined determination criterion using the image characteristic of the content analyzed by the analyzer, a predicted deterioration rate obtained by predicting a rate of deterioration of the image characteristic of the enlarged image that will occur when the image of the content is enlarged, and the predetermined determination criterion;
- and
- a pixel converter configured to perform pixel conversion of the image of the content to generate the enlarged image, the enlarged image having the number of display pixels determined by the number-of-pixels determining unit, and to output the enlarged image to the display unit.
A display control method of displaying on a display unit an enlarged image that represents enlargement of an image of content, the display unit having a number of pixels greater than a number of pixels of the content, the display control method comprising:
- analyzing an image characteristic of the enlarged image;
- determining a number of display pixels of the enlarged image so that the image characteristic satisfies a predetermined determination criterion;
- and
- performing pixel conversion of the image of the content to generate the enlarged image, the enlarged image having the number of display pixels, and outputting the enlarged image to the display unit.
