Description of the Invention: [Technical Field] [0001] The present invention relates to a delay compensation system, and more particularly to a two-dimensional (2D) to three-dimensional (3D) delay compensation system and method. [Previous Technician ί] [0002] In the past, films played on flat-panel display devices, such as LCD TVs, were two-dimensional (2D) images, and with the development of 3D imaging technology, many applications that exhibit 3D visual effects are increasingly A variety of, for example, 3D movies, 3D games, merchandise production, etc., thus making 3D imaging systems more practical and universal [0003] to achieve 3D imaging effects, in addition to the use of 3D displays, but also for general function displays Connected to a two-dimensional to three-dimensional converter to achieve. Referring to the first figure, it is a block diagram of a conventional two-dimensional to three-dimensional imaging system. The one-dimensional to two-dimensional imaging system 1 includes a two-dimensional to three-dimensional converter (2D-to-3D Conversion Box); 13 and a shutter glasses. (shutter glasses) i5, and use a liquid crystal television with a display device u. The two-dimensional to three-dimensional converter 13 is connected to the display device for converting a 2D movie into a 3D format, and then transmitting it to the display device 11 for playing. Specifically, the two-dimensional to three-dimensional converter 13 generates a left image and a right (R) image by the original 2D film by the DEPTH IMAGE -BASED RENDERING (DIBR) technology and rotates to the display device 11 for playback. 0004] The shutter glasses 15 have a left lens 151 and a right lens 153, a wire. The one-dimensional to three-dimensional converter 13 sends a sync-synchronization number to control the left and right lenses 151 of the shutter glasses 15 while rotating the left and right images. 153 switch to control left 5 form number tear 01 帛 4 pages / total 21 stomach brother 201223242 piece 151, 旎 receive left image, and right lens 153 can only receive right image. Therefore, when the user wears shutter glasses 15 to view the display Device丨 When playing left and right images, 'three-dimensional effects will occur due to binocular disparity. [0005] Ο [0006] Ο [0007] However, the converted left and right images are transmitted to the display device. After being played, the image processing is processed differently by the image processor (Image 〇cessor) 111 built in the display device 11, so that the time when the shutter glasses 15 receives the image is delayed, and the lens switching time is caused. The receiving image time is not synchronized, which makes the complementary imaging effect not good. Therefore, it is urgent to propose a novel delay compensation system and method thereof, which can compensate the delay caused by image processing and improve the 3D imaging effect. One of the above objects of the present invention is to provide a two-dimensional to three-dimensional delay compensation system and a method thereof, which can compensate for the delay caused by image processing of the left and right images by the display device, thereby improving the 3D imaging effect. A two-dimensional (2D) to three-dimensional (3D) delay compensation system is disclosed for matching a display device. The system comprises a two-dimensional to three-dimensional converter and a shutter glasses. The two-dimensional to three-dimensional converter is coupled to the display device, and transmits at least one calibration pattern to the display device, and transmits each correction map. While the image is waiting for a delay, a shutter control signal is issued. The shutter glasses have a left lens and a right lens, which receive a shutter control signal to control the opening and closing of the right lens and the left lens. A detection unit is included for sensing the corrected image and then transmitting a 099140566 form number A0101 page 5 / 21 page 0992070656-0 201223242 to adjust the signal to the 2D to 3D converter. Wherein, if the detecting unit determines that the sensed corrected image is complete, then sends a synchronized signal to the two-dimensional to three-dimensional converter, and when the two-dimensional to three-dimensional converter receives the adjustment signal, the delay is appropriately adjusted. Time until the sync signal is received. [0008] The present invention further discloses a two-dimensional (2D) to three-dimensional (3D) delay compensation method for synchronizing a shutter glasses to a movie played by a display device, and the display device is externally connected to a two-dimensional rotation. 3D converter. The method includes the following steps: First, the two-dimensional to three-dimensional converter transmits at least one calibration pattern to the display device display: after waiting for a delay time, a shutter control signal is sent to control the shutter glasses. A right lens and a left lens are opened and closed; then, the corrected image is sensed; finally, whether the delay time is to be adjusted is determined according to the sensing result. Thereby, the shutter control signal is sent after waiting for the adjusted delay time to control the right lens and the left lens to open and close in time to receive the movie in synchronization. [Embodiment] [0009] Please refer to the second figure, which is a block diagram of a two-dimensional (2D) to three-dimensional (3D) delay compensation system according to an embodiment of the present invention. As shown in the second figure, the two-dimensional to three-dimensional delay compensation system 2 (hereinafter referred to as "delay compensation system 2") includes a two-dimensional to three-dimensional converter (2D-t〇-3D Conversion Box) 23 and a shutter glasses ( The shutter glasses 25 are used in conjunction with a display device 21. The two-dimensional to three-dimensional converter 23 is externally connected to the display device 21 for converting a 2D movie into a 3D format and transmitting it to the display device 21 for playback. Specifically, the 2D film is composed of a continuous plurality of frames, and the two-dimensional to three-dimensional converter 23 is drawn by the depth image 099140566 Form No. A0101 Page 6 / 21 pages 0992070656-0 201223242 [0010] ❾ [ 0011] DEPTH IMAGE-BASED RENDERING (DIBR) technology calculates binocu-lar disparity for each facet in the original 2D movie and produces left (L) image and right (R) The image 'is outputted to the display device 21 in sequence. The shutter glasses 25 have a left lens 251 and a right lens 253. The two-dimensional to three-dimensional converter 23 sends a shutter control signal to automatically switch the imaging functions of the left and right lenses 251, 253 to control the left lens. The 251 can only receive the left image, while the right lens 253 can only receive the right image. For example, if the update frequency of the input 2D movie is 60 Hz, the two-dimensional to three-dimensional converter 23 converts it into a 3 & lattice of litflz, and sends a shutter control signal to control the left and right lenses 251, 253 to receive corresponding ones. Synchronous kneading means to receive left and right images of 60 Hz each. The display device 21 includes an image processor (Image Pr's cessor) 211 for receiving the converted left and right images of the 3D format for various processing, such as adjusting brightness, chroma, contrast, etc., and then placing the left and right shadows. :;;· "'·/ ;:, . Like playing to the left and right lenses 251, 2S3 is scattered. In one embodiment, the display device 21 is, but not limited to, a plasma display panel (PDP or Plasma TV), a liquid crystal television (Liquid Crystal Display TV, LCD TV), or a vacuum image tube television (Cathode). Ray Tube TV, CRT TV). [0012] The two-dimensional to three-dimensional converter 23 of the present invention stores at least one calibration pattern in advance. In a specific embodiment, the corrected image is, but not limited to, a completely black image (completely black pattern) ) or a completely white pattern. Before converting the 2D movie, the 2D to 3D converter 23 will first transmit 099140566 Form No. A0101 Page 7 / Total 21 Page 0992070656-0 201223242 Send the corrected image to the display device 21, and estimate that the shutter glasses 25 receive the image processing The time of the corrected image processed by the 211, and thus the left and right lenses 25 1, 253 of the shutter glasses 25 are controlled to open and close to synchronously receive the corrected image. [0013] The shutter glasses 25 further include a detecting unit 3 for sensing whether the corrected image is complete. Please refer to the third figure, which is a schematic circuit diagram of the detecting unit 3 according to the embodiment of the present invention. The detecting unit 3 is disposed on the right lens 253 or the left lens 251. As shown in the third figure, the detecting unit 3 includes a voltage dividing circuit 31 and a comparator 33. The voltage dividing circuit 31 has a photo-sensitive resistor %, which changes the resistance value according to the brightness of the corrected image. For example, when the corrected image is brighter, the resistance value of the photosensitive resistor % is smaller; When the corrected image is darker, the resistance value of the photosensitive resistor is larger. The comparator 33 is coupled to the voltage dividing circuit 31 for comparing the voltage dividing value Vd generated by the voltage dividing circuit 31 with a threshold value TH as a basis for determining whether to delay the delay time of the shutter control signal. Among them, the threshold value TH can be set depending on the actual application, for example, slightly smaller than the voltage value Vcc. [0014] When the full black image is taken as the corrected image, and the detecting unit 3 is disposed on the right lens 253 as an example, the two-dimensional to three-dimensional converter 23 transmits the corrected image of all black to the display device 21, A shutter control signal is issued after a delay time to turn off the development of the left lens 251. After the delay time, only the right lens 253 receives the all black corrected image processed by the image processor 211, and the photoresistor 1? 2 on the right lens 253 is based on the sensed corrected image. The brightness determines the magnitude of the partial pressure value Vd. When the right lens 253 receives a complete black-corrected image, the photoresistor 099140566 Form No. A0101 Page 8 of 21 0992070656-0 201223242 The resistance value of the ruler 2 becomes a maximum value, so that the voltage division value Vd Approaching the maximum value 'such as Vcc. The comparator 33 further compares the divided voltage value Vd with the threshold value TH. In this embodiment, if it is determined that the partial pressure value Vd is greater than the threshold value TH, it indicates that the right lens 2 5 3 receives a complete or nearly complete black. Correcting the image, outputting a synchronized signal to the two-dimensional to three-dimensional converter 23, indicating that the currently set delay time coincides with the time when the image processor 2 processes the corrected image, so that the corrected image can be synchronously right The lens 253 receives; conversely, if it is determined that the partial pressure value is less than the threshold TH, it means that the image processor 211 processes the corrected image for less or more than the set delay time, so that the complete black cannot be accurately received. Correcting the image outputs an adjustment signal to the two-dimensional to three-dimensional converter 23, and when the two-dimensional to three-way converter 23 receives the adjustment signal, 'the length of the delay time is appropriately adjusted' until the synchronized signal is received. . [0015] Similarly, the corrected image may also be an all-white image, the detecting unit 3 may also be disposed on the left lens 251, and the photoresistor R may also be disposed at the position of the resistor 1{5], and the comparator The judgment rule of 33 can also be appropriately adjusted according to the circuit design. For example, if it is judged that the life pressure 谆Vd is smaller than the threshold value TH, the synchronized signal is output, otherwise the adjustment signal is output. In a specific embodiment, the two-dimensional to three-dimensional converter 23 continuously transmits the full black image and the all white image, and simultaneously transmits a shutter control signal after waiting for the delay time while transmitting each of the corrected images. The left and right lenses 251, 253 are opened and closed until the synchronized signal is received, which means that the left and right lenses can simultaneously receive the full black and all white images. The design of the same concept as the above-mentioned invention is intended to be within the scope of the invention and is not limited by the disclosure. In order to further understand the operation of the present invention, please refer to the fourth figure, which is 099140566 Form No. A0101 Page 9 / Total 21 0992070656-0 201223242 A flow chart of the two-dimensional to three-dimensional delay compensation method of the embodiment of the present invention. Please refer to the second and third figures together for the relevant system architecture. The corrected image of the embodiment is a full black image, and the detecting unit 3 is disposed in the right lens 253. The steps of the two-dimensional three-dimensional delay compensation method are as follows: Before playing the 2D movie The delay compensation system 2 is initialized first, and thus enters a correction stage. First, the two-dimensional to three-dimensional converter 23 transmits a predetermined corrected image to the display device 21 (step S401), and waits for a preset delay time to issue a shutter control. The signal is used to control the opening and closing time of the left and right lenses 251, 253 (step S403). After receiving the corrected image, the display device 21 performs image processing on the image (step S405). [0017] Next, the detecting unit 3 on the right lens 253 starts sensing the corrected image displayed by the display device 21 (step S407), generates a partial pressure value Vd according to the brightness degree of the corrected image, and determines whether the partial pressure value is It is greater than the preset threshold value (step S409). If yes, it means that the time for the image processing by the display device 21 is equal to or far from the current preset delay time, so that the right lens 253 receives a complete black corrected image, thereby achieving the synchronization effect, and then A synchronized signal is sent to the two-dimensional to three-dimensional converter 23 (step S411). [0018] If the determination in step S409 is negative, it indicates that the shutter control signal controls the right lens 253 to open too early or too late, and cannot receive the processed corrected image synchronously, so an adjustment signal is sent to the second The three-dimensional converter 23 is continuously rotated to adjust the delay time (step S413). After receiving the adjustment signal, the two-dimensional to three-dimensional converter 23 appropriately adjusts the length of the delay time, and repeats steps S401-S409 until the synchronized signal is received. [0019] In a specific embodiment of the present invention, the corrected image of step S401 is 099140566, form number A0101, page 10, total 21 page 0992070656-0 201223242 is issued periodically and intermittently, for example: a full black correction The image is followed by an all-white corrected image, and the like, and the continuous output is controlled, and the right lens and the left lens are respectively controlled to receive the all-black corrected image and the all-white corrected image in synchronization, but are not limited. . [0020] After the initialization process is completed, the user can wear the shutter glasses 25, and input the 2D movie to be viewed into the two-dimensional to three-dimensional converter 23 to further convert it into a continuous right image and a left image (steps). S415). Then, the right image and the left image are outputted to the display device 21 at intervals (step S417), _ and the adjusted delay time is used to issue a shutter control signal (step S419), that is, each image is transmitted (right image or At the same time as the left image, the shutter control signal is issued after waiting for the time (delay time) for compensating for the image processing to control the left and right lenses 251, 253 to receive the left and right images in a time-division manner (step S421), and the synchronization effect is achieved.
