GREYSCALE ANIMATION
Greyscale animation. In accordance with a first method embodiment, an animation region of an electronic display is determined. The animation region is set to display a flash-mitigating background color pattern. An animation sequence is displayed in the animation region. The flash-mitigating background color pattern may include a checkerboard pattern of alternating grey colored picture elements.
1 . A method comprising:
determining an animation region of an electronic display;
setting said animation region to display a flash-mitigating background color pattern; and
displaying an animation sequence in said animation region.
2 . The method of claim 1 wherein said flash-mitigating background color pattern comprises a checkerboard pattern comprising alternating grey colored picture elements.
3 . The method of claim 2 wherein said checkerboard pattern further comprises white colored picture elements that alternate with said grey colored picture elements.
4 . The method of claim 2 wherein said checkerboard pattern further comprises black colored picture elements that alternate with said grey colored picture elements.
5 . The method of claim 1 wherein said electronic display comprises an electronic ink type display.
6 . The method of claim 5 wherein said electronic display is characterized in that an animation transition to or from a grey colored picture element from or to a black or white colored picture element is constrained by said electronic display to require an intermediate transition to an undesired color.
7 . The method of claim 1 wherein said displaying comprises changing only black or white colored picture elements to the other of white or black colored picture elements.
8 . A computer system comprising:
a processor;
a display device, coupled to said processor, capable of displaying white, black and at least one intermediate level of grey;
logic configured to control and display greyscale animation by displaying a black and white animation against a flash-mitigating background color pattern.
9 . The system of claim 8 wherein said flash-mitigating background color pattern comprises a checkerboard pattern comprising grey colored picture elements alternating with white colored picture elements.
10 . The system of claim 8 wherein said flash-mitigating background color pattern comprises a checkerboard pattern comprising grey colored picture elements alternating with white colored picture elements.
11 . The system of claim 8 wherein said electronic display comprises an electronic paper type display.
12 . The system of claim 11 wherein said electronic display is characterized and requiring display of a white colored picture element in order to change a black colored picture element to a grey colored picture element.
13 . The system of claim 8 wherein said logic is further configured to display said greyscale animation without changing a grey colored picture element of said flash-mitigating background color pattern.
14 . An article of manufacture comprising a computer readable media having instructions stored thereon that, responsive to execution by a computing device, cause said computing device to perform operations comprising:
determining an animation region of an electronic display;
setting said animation region to display a flash-mitigating background color pattern; and
displaying an animation sequence in said animation region.
15 . The article of manufacture of claim 1 wherein said flash-mitigating background color pattern comprises a checkerboard pattern comprising alternating grey colored picture elements.
16 . The article of manufacture of claim 2 wherein said checkerboard pattern further comprises white colored picture elements that alternate with said grey colored picture elements.
17 . The article of manufacture of claim 2 wherein said checkerboard pattern further comprises black colored picture elements that alternate with said grey colored picture elements.
18 . The article of manufacture of claim 1 wherein said electronic display comprises an electronic ink display.
19 . The article of manufacture of claim 5 wherein said electronic display is characterized in that an animation transition to or from a grey colored picture element from or to a black or white colored picture element is constrained by said electronic display to require an intermediate transition to an undesired color.
20 . The article of manufacture of claim 1 wherein said displaying comprises changing only black or white colored picture elements to the other of white or black colored picture elements.
