Abstract
A method and apparatus for providing a flicker filter for an interlaced video display. Content is analyzed to determine what type of filter or filter characteristics selected from a plurality of available filters or filter characteristics can provide the better display of the content. Based on this analysis, the filter characteristics are selected and used for flicker filtering the content for display.
Claims28
A flicker filter for an interlaced video display, comprising:
- means for receiving content for display on said interlaced video display;
- a flicker filter having a plurality of selectable filter characteristics;
- a content analyzer which analyzes the content to determine which of the plurality of filter characteristics to use for flicker filtering said content for display on said interlaced video display, wherein the analysis comprises making a determination as to whether the file contains graphics information or text information, and if the file contains text information the analysis further comprises an analysis of a language type or analysis of a font forming a part of the text information.
A flicker filter for an interlaced video display, comprising:
- means for receiving content for display on said interlaced video display;
- a plurality of flicker filters each having respective filter characteristics;
- a switch coupled to the filters for selecting one of the plurality of filters for filtering of images to be displayed on the interlaced video display;
- and
- a content analyzer which analyzes the content to determine which of the plurality of filters to use for flicker filtering said content for display on said interlaced video display. wherein the analysis comprises making a determination as to whether the file contains graphics information or text information, and if the file contains text information the analysis further comprises an analysis of a language type or analysis of a font forming a part of the text information.
A method of providing a flicker filter function to an interlaced video display, comprising:
- receiving content to be displayed on the interlaced video display;
- analyzing the content to be displayed;
- and
- selecting a filter characteristic for flicker filtering based upon the analysis of the content for display on said interlaced video display, wherein the analysis comprises making a determination as to whether the file contains graphics information or text information, and if the file contains text information the analysis further comprises an analysis of a language type or analysis of a font forming a part of the text information.
A method of providing a flicker filter function to an interlaced video display, comprising:
- receiving content to be displayed on the interlaced video display, the content comprising a graphics script file;
- analyzing the content to be displayed by determining a font type, a font size, and a language and by analyzing a graphic object;
- selecting a filter characteristic by selection of a filter algorithm and a plurality of filter coefficients from a lookup table for flicker filtering based on the analysis of the content;
- filtering said content using the selected filter characteristics;
- and
- displaying the content on the interlaced display.
An electronic storage medium storing instructions which, when executed on a programmed processor, carry out a method of providing a flicker filter function to an interlaced video display, comprising:
- receiving content to be displayed on the interlaced video display;
- analyzing the content to be displayed by determining a font type, a font size, and a language and by analyzing a graphic object;
- and
- selecting a filter characteristic for flicker filtering based upon the analysis of the content.
