Definitions

  • the present invention generally relates to a method for overlapping between graphic and video images, and more particularly to a method and system for overlapping and adjusting blending factors of various video/graphic images.
  • the single frame buffer architecture and the dual frame buffer architecture are usually used to merge and display graphic and video images.
  • the method of deciding to alternatively display video images or graphic images in the dual frame buffer architecture is to find chroma keying by looking up a particular color entry of the color lookup table.
  • another method of that is black detection; in this regard, using the principle that black is mostly easy to be detected and therefore takes black as one kind of chroma keying.
  • Both of the two methods described above take the pixels of graphic images as transparency and then video images will be displayed when a particular color (for instance, chroma keying or black) in the pixel streams is detected.
  • FIG. 1 depicts a conventional method for overlapping between graphic and video images.
  • a display frame 150 is composed of a video image 100 and a graphic image 110 , wherein the video image 100 and the graphic image 110 respectively send the corresponding pixels relative to the display frame 150 at the same time.
  • the overlapped area 120 of the graphic image 110 can be filled with chroma keying, and using a detector 140 to detect whether it has chroma keying or not when the pixel streams of graphic images are sent to multiplexer 130 .
  • the detecting result shows that it has chroma keying, and then multiplexer 130 chooses pixels of the video image 100 for output; otherwise, choosing pixels of the graphic image 110 for output.
  • the prior art is usually restricted by overlapping of a graphic image and a video image or overlapping of a graphic image and a frame; moreover, when the source of the frame has various graphic images or video images, the flexibility of the above-mentioned method is restricted and not enough to the applications of dynamic images.
  • the present invention provides an adaptive pixel-based blending method which includes the steps, respectively acquiring a corresponding pixel and an adjustable blending factor in accordance with a plurality of input signals; and generating an output pixel in accordance with a blending method.
  • the present invention also provides an adaptive pixel-based blending system which includes the means, a pixel and blending factor generating unit which is configured to respectively generate a corresponding pixel and a blending factor in accordance with a plurality of input signals; and a mixer which is configured to generate an output pixel in accordance with a blending method, the plurality of pixels and the plurality of blending factors.
  • the present invention provides a video-processing chip which includes the means, a blending factor generating module which is configured to respectively generate a plurality of corresponding blending factors in accordance with a plurality of input signals; and a mixer which is configured to generate an output pixel in accordance with a plurality of source pixels and the plurality of blending factors.
  • the method and system according to the embodiments of the present invention can dynamically change the blending factor of pixels by a programmable procedure in the pixels-extracting process; and it is therefore increase the flexibility and the applications of overlap between multi-input video images and graphic images.
  • FIG. 1 schematically shows the diagram of conventional method for overlapping between graphic and video images
  • FIG. 2 schematically shows the flow chart of the adaptive pixel-based blending method according to one preferred embodiment of the present invention
  • FIG. 3A schematically shows the diagram of the adaptive pixel-based blending system according to one preferred embodiment of the present invention
  • FIG. 3B schematically shows the diagram of the adaptive pixel-based blending system according to another preferred embodiment of the present invention.
  • FIG. 4 schematically shows the diagram of the video-processing chip according to one preferred embodiment of the present invention.
  • step 200 is respectively acquiring a corresponding pixel and an adjustable blending factor in accordance with each of a plurality of input signals.
  • each of the input signals is a pixel index value of indirect colors, thus the way that looking up a color lookup table can generate each pixel of them.
  • the adjustable blending factor can be formed by partial bits of the pixel value.
  • step 220 is generating an output pixel in accordance with a blending method, wherein the output pixel is generated by the blending method in accordance with the pixels of each signal and the blending factor.
  • each of signal A, B and C respectively generates pixel 1 , 2 and 3 , and each pixel of them is composed of a red value (R), a green value (G) and a blue value (B). Otherwise, each pixel of them is composed of a luminance value (L) and a chrominance value (C).
  • each of the blending values is respectively (50, 50, 50), (100, 100, 100) and (200, 200, 200), and each of the blending factors is respectively 200%, 100% and 25%, thus multiplying each of the pixel values by the blending factors. It is therefore that we can get each of the blending values, which is respectively (100, 100, 100), (100, 100, 100) and (50, 50, 50); moreover, adding them for obtaining an output pixel, (250, 250, 250). It should be appreciated that, each of the blending values is limited to a range, for instance, each of the blending values is restricted that not greater than a maximum color value and the output pixel is limited to being not greater than the maximum color value; otherwise, an overflow condition will occur.
  • the maximum color value represents the maximum of the pixels; for instance, the maximum color value is 255 when using in a 256-colors environment, which the color range is from 0 to 255.
  • all of the blending values and the output pixel value is restricted within the maximum color value of the output pixel value. For instance, when each of the maximum color values of the output red, green and blue value of the output pixel, is respectively 63, 31 and 63; and then each of RGB values of each blending value (generated by the pixels of all signals and the blending factors) is respectively limited to 63, 31 and 63. Furthermore, each of RGB values of the output pixel (generated by the way that adding each blending value) is also respectively limited to 63, 31 and 63.
  • the contents of various signals can generate the pixels with the same color values and different blending factors by dynamically changing the contents of the color entries; moreover, when the contents of various signals are invariable, it can achieve a special display effect by dynamically changing the blending factor. For instance, when the contents of a signal are A, B, C, D and E, generating the pixels (that are all color 1) by verifying the color lookup table, while the blending factors are 100%, 75%, 50%, 25% and 0% respectively; thus the pixels generated by the signal will be gradually changed from color 1 to diluted color at different timing. And finally, it generates a fade-out effect.
  • each of the signal sources simply sends the signal contents related with the pixels, and the same pixels with different blending factors are sent in different contents of signals; thus there is no need to send the information of both pixels and blending factors. Further, it will save the storage space and the communication cost of source signals. For instance, when each blending factor related with each pixel requires 8 bits to represent a frame with 1024 ⁇ 768 resolution and then each frame requires 6,291,456 bits, results in large cost of displaying 30 frames per second.
  • FIG. 3A schematically shows the diagram of the adaptive pixel-based blending system according to one preferred embodiment of the present invention.
  • the system includes a pixel and blending factor generator 300 , configured to respectively generate a corresponding pixel and a blending factor in accordance with a plurality of input signals; and a mixer 340 , configured to generate an output pixel in accordance with a blending method, the plurality of pixels and the plurality of blending factors.
  • FIG. 3B schematically shows the diagram of the adaptive pixel-based blending system according to another preferred embodiment of the present invention.
  • the system includes a pixel and blending factor generator 300 , wherein the generator 300 further includes various programmable lookup tables 3101 ⁇ 310 N, configured to output corresponding pixels in accordance with a corresponding color entry of a color lookup table (which is in response to each input signal).
  • the system further includes various blending factor generators 3201 ⁇ 320 N, each blending factor generator is configured to receive an input signal for generating corresponding blending factors.
  • the blending method and other related details of the embodiment is the same as the former embodiment, and thus there is no need to give unnecessary details.
  • FIG. 4 schematically shows the diagram of the video-processing chip according to one preferred embodiment of the present invention.
  • the video-processing chip includes a blending factor generating module 420 , configured to respectively generate a plurality of corresponding blending factors in accordance with a plurality of input signals; and a mixer 440 , configured to generate an output pixel in accordance with a plurality of source pixels and the plurality of blending factors.
