Display processing system and method
View Patent ↗A method includes storing a transparency value. A color level value is stored in a set of color bits. The color level value is multiplied by the transparency value, by bit-shifting the set of color bits by a number of bit positions indicated by the transparency value.
1. A method for adjusting pixel values for transparency comprising:
storing a transparency value of a pixel;
storing a color level value of the pixel in a set of color bits; and
adjusting the color level value by bit-shifting the set of color bits by a number of bit positions indicated by the transparency value without multiplying the color bits by the transparency value.
2. The method of claim 1 further comprising a flipping action so as to yield a transparency scale of 0%, 12.5%, 25%, 50%, 75%, 87.5% and 100%.
3. The method of claim 1 wherein the storing actions and the adjusting action are performed by a mobile communication device.
4. The method of claim 1 wherein the bit-shifting is performed in the same memory location in which the color level value is stored.
5. The method of claim 1 wherein the bit-shifting enables a transparency scale comprising a series of percentages that are obtained by successive divisions by two, and the method further comprises a flipping action to yield, for each of the percentages, another percentage equivalent to 100% minus the respective percentage.
6. The method of claim 1 further comprising bit masking.
7. An electronic device comprising:
a memory store configured to store a transparency value and also to store a color level value in a set of color bits; and
a processor configured to adjust the color level value by bit-shifting the set of color bits by a number of bit positions indicated by the transparency value without multiplying the color bits by the transparency value.
8. The electronic device of claim 7 wherein the processor is further configured to perform a flipping action so as to yield a transparency scale of 0%, 12.5%, 25%, 50%, 75%, 87.5% and 100%.
9. The electronic device of claim 7 wherein the memory store and the processor are parts of a mobile communication device.
10. The electronic device of claim 7 wherein the bit-shifting is performed in the same memory location in which the color level value is stored.
11. The electronic device of claim 7 wherein the bit-shifting enables a transparency scale comprising a series of percentages that are obtained by successive divisions by two, and the method further comprises a flipping action to yield, for each of the percentages, another percentage equivalent to 100% minus the respective percentage.
12. The electronic device of claim 7 further comprising bit masking.
13. A non-transitory computer-readable storage medium or mediums encoded with instructions that cause an electronic device to store a transparency value;
store a color level value in a set of color bits; and
adjust the color level value by bit-shifting the set of color bits by a number of bit positions indicated by the transparency value without multiplying the color bits by the transparency value.
14. The non-transitory computer-readable storage medium or mediums of claim 13 wherein the bit-shifting is performed in the same set of color bits in which the color level value is stored.
