Embodiment Construction
[0028] Please refer to figure 1 , figure 1 It is a schematic block diagram of an embodiment of an apparatus 100 for adjusting the three-dimensional depth of an object according to the present invention. The device 100 is used for dynamically adjusting the 3D depth of an additional object of a stereoscopic image signal V_3D. The device 100 includes a calculation circuit 105 and an adjustment circuit 110. The calculation circuit 105 is used to detect the three-dimensional depth of a specific object in multiple frames of the stereoscopic image signal V_3D, and the adjustment circuit 110 is coupled to the calculation circuit 105 and used for detecting Adjusts the 3D depth of additional objects to the 3D depth of a specific object. In detail, the additional object can be a subtitle, an On Screen Display (OSD) menu, a program menu, or other additional image or text objects. Although the later description of this embodiment uses subtitles as an example to explain The operation o...

The invention provides a method and device for regulating a three-dimensional depth of an object as well as a method and device for detecting the three-dimensional depth of the object. The method for regulating the three-dimensional depth of the object comprises the steps of: carrying out block matching on a left / right eye picture in a three-dimensional image signal to figure out a movement vector of a specific object and obtaining the three-dimensional depth of the specific object; and regulating a three-dimensional depth of an additional object by using the obtained three-dimensional depth of the specific object, wherein the additional object can be a subtitle, a on-screen display menu or a program menu.
Description
technical field [0001] The present invention refers to a mechanism capable of detecting the three-dimensional depth of a main object in a stereoscopic image signal and dynamically adjusting the three-dimensional depth of an additional object, especially a block comparison of left / right frames in a stereoscopic image signal to calculate movement A method and apparatus for detecting the 3D depth of a main object using a vector and adjusting the 3D depth of an additional object using the detected 3D depth of the main object. Background technique [0002] Please refer to Figure 5 , Figure 5 It is a schematic structural diagram of an image frame 500 in a 3D stereo image signal in the prior art. In the video frame 500, P1 is the video object closest to the human eye, that is, the stereoscopic video object with the shallowest 3D depth, and P2 is the video object farthest from the human eye, that is, the stereoscopic video object with the deepest 3D depth. image object, and P3 is...
