Description

Technical Field

[0001] The present invention relates to the field of external device synchronization, and in particular to an external device synchronization device based on video image frame frequency time difference and a use method thereof. Background Art

[0002] With the continuous development of stereoscopic image technology, the way of presenting stereoscopic images in various scenes such as major cinemas, televisions and online media is becoming more and more common. Under the existing technical level, stereoscopic images are mostly presented by various special stereoscopic display devices and projection devices, and ordinary display devices cannot view stereoscopic images. According to the products currently on the market, stereoscopic images are mainly viewed through polarized light glasses, flash glasses and red and blue glasses. Among them, the polarized light method is expensive and is only applicable to scenes such as cinemas; the red and blue method has an unsatisfactory viewing effect and the application scene penetration rate is not high; the flash method is more popular in personal and family scene applications, but it is limited by the fact that the display device must be a device with a stereoscopic image display function, and the user cost is much higher than that of ordinary display devices. For this reason, the present invention proposes an external device synchronization device based on the video image frame rate time difference and a method of use to synchronize the video source with the external device. Summary of the invention

[0003] The object of the present invention is to provide an external device synchronization device based on video image frame rate time difference and a method for using the same, so as to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: an external device synchronization device based on video image frame rate time difference and a method for using the same, comprising:

[0005] An image recognition module, used for recognizing 3D image data of an image source;

[0006] An image segmentation module segments the recognized image data according to the number of frames;

[0007] A calculation module calculates the corresponding start time of each frame of segmented image data;

[0008] The device synchronization module synchronizes the external device based on the start time of each frame of image data calculated by the calculation module.

[0009] Preferably, the image recognition module uses a photosensitive element sensor to recognize image data.

[0010] Preferably, the calculation module uses an average sampling method to calculate the start time corresponding to each frame of segmented image data, that is, uses the previous statistical result to perform the calculation.

[0011] Preferably, the device synchronization module synchronizes the external device with the video source based on the result of the calculation module, thereby performing video presentation.

[0012] Preferably, the device synchronization module performs synchronization of image data and external devices based on the difference between left and right frames of video images of existing display devices and the relatively fixed rule that the frame frequency time difference between left and right frames is relatively fixed.

[0013] According to the above-mentioned method for using the external device synchronization device based on the video image frame frequency time difference, the method comprises the following steps:

[0014] Step S1, using an image recognition module to collect and identify an external image data source;

[0015] Step S2, using an image segmentation module to segment the image data identified in step S1 according to the number of frames;

[0016] Step S3, using a calculation module to calculate the corresponding initial time for each frame of image data segmented in step S2 according to an average sampling method;

[0017] Step S4, based on the calculation result of the calculation module in step S3, the synchronization controller of the device synchronization module synchronously connects the external data source with the external device, and presents the previous and next frames of the image on the display device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention uses an image recognition module to collect and recognize an external image data source, then uses an image segmentation module to segment the recognized image data according to the number of frames, then uses a calculation module to respectively calculate the corresponding initial time for each frame of the segmented image data according to an average sampling method, and uses a synchronization controller of a device synchronization module to synchronously connect the external data source with an external device based on the calculation result of the calculation module, so as to present the front and back frames of the image on the display device, and based on the difference between the left and right frames of the video image of an ordinary display device and the relatively fixed rule of the frame frequency time difference of the left and right frames, calculates the start time of each frame of the image, which is used to synchronize the external device, and facilitates the synchronous connection of the image source and the external device, so as to present a three-dimensional image; this is achieved by crossing the display device and the image source, and has the characteristics of small size, low cost, and easy promotion.
