Image analysis of display content for dynamic adjustment of a continuous scan display

A computing system, comprising:

• a display screen;
• a processor;
• and
• a storage device storing instructions that, when executed by the processor, perform a method of:
• accessing a histogram of one or more characteristics a reference image represented in a first image format having a first bit depth;
• using information represented by the histogram to determine whether to convert the reference image to a second format having a second bit depth that is smaller than the first bit depth, wherein determining whether to convert comprises computing an image conversion score based on the histogram;
• responsive to a positive determination of said determining, converting the reference image to a modified image represented in the second image format having the second bit depth;
• rendering the modified image that is in the second image format having the second bit depth for display on the display screen;
• and
• responsive to a negative determination of said determining, rendering the reference image that is in the first format having the first bit depth for display on the display screen;
• wherein the determining whether to convert comprises applying a scoring criterion in response to a static image period of the display screen;
• wherein the determining whether to convert further comprises comparing the image conversion score with one or more threshold values.

A method for generating images for display on a display screen of a computing device, the method comprising:

• generating a histogram of one or more characteristics of a reference image represented in a first image format having a first bit depth;
• detecting an image conversion condition;
• responsive to detection of the image conversion condition, using information represented by the histogram to determine whether to convert the reference image to a second format having a second bit depth that is smaller than the first bit depth, wherein determining whether to convert comprises computing an image conversion score based on the histogram according to a scoring criterion in response to a static image period of the display screen;
• comparing the image conversion score to one or more threshold values;
• selecting the second mage format from a plurality of image formats based on the comparing and the detecting,
• wherein each image format of said plurality of image formats has a bit depth smaller than the first bit depth;
• responsive to a determination that the comparing produces a first result:
• converting the reference image to a modified image of the second image format having the second bit depth than the first image format;
• and rendering the modified image that is in the second image format for display on the display screen;
• and
• responsive to a determination that the comparing produces a second result:
• rendering the reference image that is in the first image format for display on the display screen.
