User interface display apparatus using texture mapping method
View Patent ↗A low cost user interface display system, like on screen display (OSD), using texture mapping method is presented. The present invention only uses a little texture memory and can generate very fancy user interface display. With the method of texture mapping, even the low cost system can have a colorful, fancy user interface display. A user interface display apparatus using texture-mapping method, comprising a image module, texture patterns, display code-buffer, texture mixer and outline shape index generator to texture-maps the predefined image module in the mixing area with the texture patterns. For some existing OSD devices, the texture-mapping method also can provide a low cost approach to fancy the original OSD display output in the display device. Moreover, changing the texture pattern is very easy to system manufacture, and it can make the user interface looks good and different.
1. A user interface display apparatus, comprising:
an image module unit for providing image patterns;
a texture pattern unit for providing texture patterns;
a display code-buffer unit for arranging pattern codes which are associated with the image patterns and texture patterns to be displayed on a user interface display window; and
a mixer unit for mixing the image patterns and the texture patterns, and output a mixed signal;
wherein the mixer unit uses an alpha blending method, where output=(pattern from said image module unit)×alpha+(pattern from said texture pattern unit)×(1−alpha), and wherein the parameter alpha is a real number between 0 and 1.
2. The user interface display apparatus of claim 1 , further comprising an outline shape index generator for providing the mixing index information to define the outline shape.
3. The user interface display apparatus of claim 2 , wherein the outline shape index generator further comprising sub-window define function.
4. The user interface display apparatus of claim 2 , wherein the outline shape index generator further using alpha index for image pattern.
5. The user interface display apparatus of claim 2 , wherein the outline shape index generator further using color key method for image pattern.
6. The user interface display apparatus of claim 1 , wherein the predefined image pattern could be any combination of dot pixel.
7. The user interface display apparatus of claim 1 , wherein the texture patterns can be defined by end-user.
8. A user interface display apparatus, combined with an traditional on screen display and overlap the output signal, comprising:
an image module unit for providing image patterns;
a texture pattern unit for providing texture patterns;
a display code-buffer unit for arranging pattern codes which are associated with the image patterns and texture patterns to be displayed on a user interface display window; and
a mixer unit for mixing the image patterns and the texture patterns, and output a mixed signal;
wherein the mixer unit uses an alpha blending method, where output=(pattern from said image module unit)×alpha+(pattern from said texture pattern unit)×(1−alpha), and wherein the parameter alpha is a real number between 0 and 1.
9. The user interface display apparatus of claim 8 , further comprising an outline shape index generator for providing the mixing index information to define the outline shape.
