Description of the invention: [Technical field to which the invention pertains] The device, system and method for translating an on-screen display (On Screen Display, (10)) . < / [Prior Art] The On Screen Display (OSD) technology is widely used in image processing systems such as televisions, personal computers (PersQnal, PC), and mobile terminals. The role of SD is to display various additional messages on the screen display. For example, when we adjust the TV image, press “Dish” to change and adjust the performance indicators of the display. However, the conventional GSD technology usually displays the original video image when the SD is displayed on the screen of the TV, Pc, and mobile terminal. Referring to the fourth figure, part (e) of the fourth figure is the original video image, and part (f) is the 〇SD image. If the part (g) is not, the background color of the OSD image is first removed, even if the background color becomes Transparent, and then the 0SD image is mixed with the video image, and the image as shown in part (h) appears. The 0SD image partially masks the subsequent video image, affecting the viewing effect of the video image. If the effect of semi-transparency of the image can be achieved when the 0SD image is superimposed on the video image, the above problem will be solved. The viewer can see the additional message of the SD image and see the video image behind it at the same time. Conventional systems and methods for implementing 0SD translucency on a screen display are typically implemented using RGB (Red, Green and Blue, three primary colors) format algorithms. The translucent of the OSD image is achieved by mixing (Aipha Blending) the RGB values of the 0SD apostrophe and the value of the background video signal. The value of Alpha is within the range of 〇 to ^. Different values of Alpha are used to achieve different degrees of translucency. You can refer to the following methods: (The RGB values of the 0SD signal are recorded as ForegroundRed, ForegromdGreen, and Foregr〇undBlue respectively; the RGB values of the video signal 1262028 are BackgroundRed, BackgroundGreen, and BackgroundBlue; the value of Alpha is α) ^ BlendedRed=ForegroundRed* a +BackgroundRed* (1-α) <BlendedGreen — ForegroundGreen*a+BackgroundGreen* (la)

However, since the format is used to process signals, a multiplier is required in the operation process, and the operation is complicated. In view of the above shortcomings, there is a need for a simple, efficient device, system, and method for achieving translucency of the 0SD on the video display.

By using the apparatus, system and method for realizing 0SD translucent according to the present invention, the video signal and the 0SD signal can be translucent in the video display by simple operation in the YUV format. [Embodiment] The image signal is usually in the YJJV format during transmission and processing. Υυν (also known as YCrCb) is a color coding method adopted by the European TV system (belonging to ρΑ[system]' Υ indicates the clearness, that is, the grayscale value, and “U” and “V” indicate the chromaticity, describing the image. Color and saturation, the age of the specified pixel. Because human vision is more sensitive to the sensibility of Ming 8 1262028, it feels weaker to chromaticity. Therefore, in the case of no image display effect, compressing the γυν format signal can discard part of the chrominance signal. It is known that the RGB format hybrid (Alpha Blending) algorithm is implemented in the On Screen Display (0SD) semi-transparent method, which is not only computationally complex: it needs to convert the original YUV format signal into RGB format. The yijv format is used to realize the 0SD translucency, which is not only simple in operation, but also saves the complexity of converting the original γυν grid signal into the RGB format, and avoids the disadvantages caused by image distortion, etc. 0, ^See A figure is an architectural diagram of an implementation of an OSD translucent system of the present invention. The system includes: a video signal receiver 100, an oscilloscope receiver 2A, a ^SD^marker 300, an OSD translucent implementor 400, and a display 5. The 〇SI) translucent current device 400 further includes a buffer 41 〇, a register 420, a comparator 43 〇 , and an output control unit 440 . In the present embodiment, the buffer 41 further includes: a first buffer 412, a second buffer 414, and a third buffer 416. The video signal receiver 100 is configured to receive the video signal, and output the video signal in the γυν format, and the Yaa number in the video signal is transmitted to the first buffer 412. The capture signal is transmitted to the second buffer. 414. (10) The domain receiver 200 is configured to receive the 〇sd signal and output the yuSD signal yu 格式 in the yuV format. In the middle, the semaphore in the 0SD signal is transmitted to the third buffer, 416. In this implementation In the video, the signal received by the video signal receiver 100 is in the format of γυν. (10) The received signal is also in the format of the signal. In other embodiments of the present invention, the SD signal received by the right 0SD signal receiver 200 is not γυν The format, for example, a tiger can use a converter (not shown) to convert the leg format signal to the yuv format. For example, the following method is used to convert the RGB format to the γυν format: (0.439*R) - (0.368 * 0 - (〇.〇71*B) +128 (〇, H8*R) ~ (〇-291*G) + (0.493*B) +128 Will, ^^_1^^&300 for receiving and The current (10) signal recalls the matching data M3v3 of the U color that will be transmitted through the moon.
