Abstract
A method for developing gray scale pixels on a computer display comprises the steps of examining image content data for display on at least a portion of a computer display to determine whether the image content comprises computer graphics or continuous tone images; and choosing from among spatial and temporal gray scaling for the image content data in response to whether the image content comprises computer graphics or continuous tone images.
Claims21
A method for developing gray scale pixels on a computer display, the method comprising:
- examining image content data using the number of colors used for display on a computer display to determine whether said image content is likely to be computer graphics or likely to be continuous tone images;
- and
- choosing from among spatial and temporal gray scaling for said image content data in response to whether said image content comprises computer graphics or continuous tone images.
A method for developing gray scale pixels on a computer display comprising:
- examining image content data for display on a computer display to determine whether said image content is most likely to a first image type or a second image type;
- and
- choosing from among at least two different image processing methods in response to whether said image content data likely comprises the first image type or the second image type;
- wherein said examining comprises counting the number of unique colors in a selected run of pixels in a display frame, deciding that the image is a first image type if the number of unique colors is less than a first threshold amount, and deciding that the image is a second image type if the number of unique colors is greater than a first threshold amount.
A method for developing gray scale pixels on a computer display comprising:
- examining image content data using the number of colors used for display on a computer display to determine whether said image content is most likely to comprise computer graphics, most likely to comprise continuous tone images, or most likely to comprise computer generated images;
- and
- choosing a method for processing said image content data in response to whether said image content comprises is most likely to comprise computer graphics, continuous tone, or computer generated images.
A machine-readable medium on which are stored instructions to perform a method for developing gray scale pixels on a computer display, the method comprising:
- examining image content data using the number of colors used for display on a computer display to determine whether said image content is most likely to comprise computer graphics or most likely to comprise continuous tone images;
- and
- choosing from among spatial and temporal gray scaling for said image content data in response to whether said image content comprises computer graphics or continuous tone images.
A machine-readable medium on which are stored instructions to perform a method for developing gray scale pixels on a computer display, the method comprising:
- examining image content data for display on a computer display to determine whether said image content is most likely to a first image type or a second image type;
- and
- choosing from among at least two different image processing methods in response to whether said image content more likely comprises the first image type or the second image type;
- and
- wherein said examining comprises counting the number of unique colors in a selected run of pixels in a display frame, deciding that the image is a first image type if the number of unique colors is less than a first threshold amount, and deciding that the image is a second image type if the number of unique colors is greater than a first threshold amount.
