Abstract

There is provided an apparatus for processing an on-screen display (OSD), the apparatus including: a buffer unit receiving first dynamic guideline image information, a color determining unit determining colors for previously divided sections included in the first dynamic guideline image information from the buffering unit, and an image synthesizing unit synthesizing second dynamic guideline image information having the colors for each of the sections, determined by the color determining unit with an image from a camera. With the apparatus for processing an OSD, a user freely sets colors of a warning message, a static guideline, and a dynamic guideline, whereby the warning message, the static guideline, and the dynamic guideline can be displayed on a screen without obscuring a rearview image. In addition, a dynamic guideline can be set as different colors according to sections divided into distances from the rear of a vehicle and an image can be continuously displayed. Further, the camera module can be reprogrammed.

Claims

1. An apparatus for processing an on-screen display (OSD), the apparatus comprising:

a buffer unit receiving first static guideline image information, first dynamic guideline image information, and first message image information;

a color determining unit including a first color determination unit determining colors for each of sections with respect to the first static guideline image information from the buffering unit, a second color determination unit determining colors for previously divided sections included in the first dynamic guideline image information, and a third color determination unit determining a color of the first message image information; and

an image synthesizing unit synthesizing second static guideline image information having the colors for each of the sections determined by the first color determination unit, second dynamic guideline image information having the colors for each of the sections determined by the second color determination unit, and second message image information having the color determined by the third color determination unit with an image from a camera.

2. The apparatus of claim 1, wherein the first color determination unit determines the colors for each of the sections by using horizontal synchronous signals of the first static guideline image information, and the second color determination unit determines the colors by using section identifying information stored according to the sections included in the first dynamic guideline image information.

3. The apparatus of claim 1, wherein the image synthesizing unit includes an active pixel determining unit determining active pixels among the second static guideline image information having the colors for each of the sections determined by the first color determination unit, the second dynamic guideline image information having the colors for each of the sections determined by the second color determination unit, and the second message image information having the color determined by the third color determination unit, the active pixels being synthesized with the image from the camera.

4. The apparatus of claim 3, wherein the active pixel determining unit determines the active pixels and inactive pixels among the second static guideline image information having the colors for each of the sections determined by the first color determination unit, the second dynamic guideline image information having the colors for each of the sections determined by the second color determination unit, and the second message image information having the color determined by the third color determination unit, in a lattice form, the inactive pixels not being synthesized with the image from the camera.

5. The apparatus of claim 1, wherein the buffer unit includes:

a first buffer receiving the first static guideline image information;

a second buffer receiving the first dynamic guideline image information corresponding to a steering wheel steering angle;

a third buffer receiving third dynamic guideline image information corresponding to the next steering wheel steering angle estimated from the steering wheel steering angle; and

a fourth buffer receiving the first message image information.

6. The apparatus of claim 5, wherein further comprising:

a first decoder run-length decoding the first static guideline image information from the first buffer to thereby output the decoded first static guideline image information to the color determining unit;

a second decoder run-length decoding the first dynamic guideline image information from the second buffer to thereby output the decoded first dynamic guideline image information to the color determining unit; and

a third decoder run-length decoding the first message image information from the fourth buffer to thereby output the decoded first message image information to the color determining unit.

7. The apparatus of claim 2, further comprising a color register unit including a first color register providing color information corresponding to the section identifying information to the first color determination unit, a second color register providing color information according to the horizontal synchronous signal to the second color determination unit, and a third color register providing determined color information of the first message image information to the third color determination unit.

8. The apparatus of claim 1, wherein the image synthesizing unit includes a synthesizing region filtering unit low pass filtering the second static guideline image information having the colors for each of the sections determined by the first color determination unit, the second dynamic guideline image information having the colors for each of the sections determined by the second color determination unit, and the second message image information having the color determined by the third color determination unit.

9. The apparatus of claim 1, further comprising a position determining unit including a first position determining unit determining a position in which the second static guideline image information having the colors for each of the sections is to be displayed, in the image from the camera and a second position determining unit determining a position in which the second message image information having the determined color is to be displayed, in the image from the camera.

10. The apparatus of claim 9, wherein the first position determining unit determines the position in which the second static guideline image information having the colors for each of the section is to be displayed in the image from the camera by counting horizontal synchronous signals of the first static guideline image information and pixel values of the horizontal synchronous signals, and

the second position determining unit determines the position in which the second message image information having the determined color is to be displayed, in the image from the camera by counting horizontal synchronous signals of the first message image information.

11. The apparatus of claim 3, wherein the image synthesizing unit further includes a flicker setting unit set to block synthesizing of the active pixels of the second message image information having the determined color with the image from the camera at a preset time interval.
