The description and claims do not take the form of an element differentiated by name, but rather by functional differences. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to.

Referring to fig. 1 and 2, fig. 1 is a flowchart illustrating an operation of an image display method for processing a dynamic image signal including a plurality of consecutive image frames according to an embodiment of the present disclosure. Fig. 2 is a block diagram showing a structural configuration of an image display apparatus 100 for performing the image display method of fig. 1 according to an embodiment of the present disclosure.

The display device 100 includes a display 101 and a controller 102. The display 101 can display (play) the dynamic video signal 131 including the continuous image frames provided by the multimedia signal source 130. For example, in some embodiments of the present description, the display 101 may be various forms of projector or flat panel display. In this embodiment, the display 101 may be, but is not limited to, a projector.

The controller 102 may be used to execute the image display method shown in fig. 1. In some embodiments of the present description, the controller 102 may be (but is not limited to) built into the projector. The controller 102 may include, but is not limited to, a data receiving device 102a, a storage device 102b, and a determining device 102c. The data receiving device 102a may include a signal connection port for receiving the dynamic video signal 131 provided by the multimedia signal source 130. The determining device 102c may include a decoder 102d and a detection logic 102g for processing the motion video signal 131 and outputting the display parameters 102r to the display 101. The storage device 102b may be used to store the motion picture signal 131, the display parameter 102r, and other processing information of the determining device 102c.

The decoder 102d may be configured to analyze and identify the multimedia feature index value 102i of each of the plurality of consecutive image frames in the moving image signal 131, where the multimedia feature index value 102i of each image frame is obtained by the decoder 102d in some embodiments of the present disclosure, and may be, for example, but not limited to, color (color) feature index value, shape (shape) feature index value, brightness (brightness) feature index value, or any combination of the above index value materials.

The detection logic 102g may include an artificial intelligence (artificial intelligence, AI) algorithm for summarizing, identifying, and comparing the multimedia feature index values 102i for each image frame. After operation by the detection logic 102g, a display parameter 102r is output to the display 101. The display 101 displays the image content corresponding to the image frame on the screen 101a according to the received display parameter 102r. In some embodiments of the present disclosure, the display parameters 102r output to the display 101 may include, for example, but not limited to, color light energy distribution (RBG energy distribution) control data, contrast control data, color Gamma correction (Gamma correction) data, color coordinate control data, or any combination thereof of the above control data of the display 101.

In other embodiments of the present disclosure, the storage device 102b may be further connected to an external cloud database (not shown) through a network.

Referring to fig. 3, fig. 3 is a schematic diagram showing a series of image frame changes for performing the image display method of fig. 1 according to an embodiment of the present disclosure. First, referring to step S11, a first display parameter is output according to the first attribute data of the nth image frame. Wherein N is a positive integer greater than or equal to 1. When the controller 102 receives the moving image signals 131 related to the 1 st to the nth image frames provided by the multimedia signal source 130, it performs an operation through the determining device 102c of the controller 102 to obtain the multimedia feature index value 102i (i.e. the first attribute data), and generates the display parameters 102r (i.e. the first display parameters) of the 1 st to the nth image frames according to the operation logic, and outputs the display parameters to the display 101. The display 101 displays the image content of the corresponding image frames (e.g., the 1 st image frame to the nth image frame) on the screen 101a according to the received display parameters 102r.

For example, in this embodiment, N may be greater than 10. Among the moving image information 131 provided by the multimedia signal source 130, the 1 st image frame to the nth image frame are all the image information related to racing. The scenes of each image frame are identical and the hue changes little. Therefore, after the image information 131 of the 1 st image frame to the N th image frame passes through the determining device 102C of the controller 102, the obtained multimedia feature index values 102i, for example, include any one of the color feature index values, the shape feature index values, the brightness feature index values, or any combination thereof, may be quite close.

In other words, the 1 st image frame to the N th image frame have substantially the same first attribute data. In some embodiments, the substantially identical first attribute data refers to that the average deviation between the values in the multimedia feature index values 102i may be (but is not limited to) substantially 0% to 15%. Likewise, the display parameters 102r, including, for example, one or any combination of image color light energy distribution, contrast, color gamma, color coordinates, for displaying the images of the 1 st to nth image frames, may be quite similar, as outputted by the controller 102 to the display 101. That is, the 1 st image frame to the nth image frame have substantially the same first display parameters.

In the present embodiment, the display parameters 102r outputted from the controller 102 to the display 101 for displaying the 1 st to nth image frames V1 to Vn may specifically include a voltage-to-brightness conversion relationship Curve of the screen, which is also referred to as Gamma Curve (Gamma Curve) D1. Each gamma curve D1 includes a plurality of curves representing different colors of light, and the horizontal axis represents voltage (V) and the vertical axis represents brightness (%). Based on the gamma curve D1 and other display parameters 102r (including information such as image color light energy distribution, contrast, color light gamma value, color coordinates, etc.) output from the controller 102 to the display 101, the display 101 can convert the image information 131 from the 1 st image frame to the N-th image frame into the 1 st image frame image V1 to the N-th image frame image Vn as shown in fig. 3 for display on the screen.

Next, referring to step S12, at least one n+kth image frame is detected, and when the at least one n+kth image frame has the second attribute data, a first display parameter is output to display the n+kth image frame. Wherein K is a positive integer greater than 1. For example, in the present embodiment, K is equal to 2 (k=1), and the moving image information 131 provided by the multimedia signal source 130 is changed from the racing scene to the scene related to the forest or animal from the n+1st image frame; after the n+3 image frame, the image frame scene of the moving image information 131 may still maintain a forest or animal related scene or be converted into other scenes.

The judgment device 102C of the controller 102 performs an operation, and the obtained n+1st image frame and n+2nd image frame multimedia feature index value 102i (i.e. the second attribute data) is the first attribute data different from the 1 st image frame to the N-th image frame. At this time, if the determining device 102c of the controller 102 directly outputs the second display parameter (e.g. the gamma curve with different brightness conversion relationships) different from the first display parameter of the 1 st image frame to the N-th image frame to the display 101 according to the obtained multimedia feature index value 102i (i.e. the second attribute data), the color tone of the frame is easily changed excessively due to the sudden scene switching, resulting in a transient mosaic phenomenon and a flashing effect of the image frame, and further generating an afterimage in the eyes of the user.

Therefore, in the present embodiment, the detection logic 102g in the determining device 102 of the controller 102 forces the display 101 to output the first display parameters (e.g. the gamma curve D1) for displaying the 1 st to the N-th image frames for the n+1st and the n+2nd image frames. Then, the display 101 converts the image information 131 of the n+1st image frame and the n+2nd image frame into the n+1st image frame image vn+1 and the n+2nd image frame image vn+2, and displays the n+1st image frame and the n+2nd image frame image vn+2 on the screen 101a (as shown in fig. 3). The discomfort of the user caused by the display of the images during the scene change is alleviated by controlling the color (tone) of the first (n+1) -th (n+2) -th (n+1) -th (n+2) -th (V1) -th (n+n) -th (V1-N) th) image frame image.

It should be noted that the controller 102 may determine the value of K according to the difference between two different attribute data (i.e., the first attribute data and the second attribute data) after the scene transition (after the nth image frame). For example, in one embodiment of the present disclosure, the detection logic 102g may determine whether two adjacent image frames have the same attribute data according to the color number of each image frame (e.g., the average value of the color levels of a specific region or the whole of the image frames) as the multimedia feature index value 102i by using an artificial intelligence algorithm. And determines the number of image frames (i.e., the value of K) that will be forced to output the first display parameter before outputting the display parameter 102r and other corresponding data to the display 101. When the difference between the color numbers (average value of the color levels) of the first attribute data and the second attribute data is larger, the value of K can be larger, and the uncomfortable feeling of the display picture to the user when the picture scene is switched is further alleviated by increasing the number of the image frames which forcedly output the first display parameter.

Subsequently referring to step S13, an n+k+1-th image frame is detected, and when the n+k+1-th image frame has second attribute data, a second display parameter is output according to the second attribute data to display the n+k+1-th image frame. For example, in the present embodiment, the video information 131 provided by the multimedia signal source 130 is analyzed and compared by the determining device 102c of the controller 102, and the obtained multimedia feature index value 102i of the found n+k+1th image frame (i.e. n+3rd image frame, k=2) is substantially the same as or similar to the second attribute data of the n+1th image frame to the n+2th image frame. The determining device 102c of the controller 102 may determine that the n+3-th image frame and the n+1-th image frame have the same scene, and further output a second display parameter (e.g., a gamma curve D2 having a different brightness conversion relationship) different from the first display parameter of the 1-th image frame to the N-th image frame to the display 101 according to the second attribute data of the n+k+1-th image frame, so that the display 101 converts the image information 131 of the n+3-th image frame into the n+3-th image frame image vn+3, and displays the n+3-th image frame image vn+3 on the screen 101a so that the n+3-th image frame image vn+3 has a tone color corresponding to the forest or animal-related scene (as shown in fig. 3).

Referring to fig. 4, fig. 4 is an operation flowchart of an image display method for processing a dynamic image signal including a plurality of consecutive image frames according to another embodiment of the present disclosure. The image display method shown in fig. 4 is substantially similar to the image display method shown in fig. 1, except that the image display method shown in fig. 4 further includes an over-parameter (segment) adjustment step during scene transition.

Referring to fig. 5, fig. 5 is a schematic diagram showing a series of image frame changes for performing the image display method of fig. 4 according to another embodiment of the present disclosure. First, referring to step S41, a first display parameter is outputted according to the first attribute data of the nth image frame. Wherein N is a positive integer greater than or equal to 1. When the controller 102 receives the moving image signals 131 related to the 1 st to the nth image frames provided by the multimedia signal source 130, it performs an operation through the determining device 102c of the controller 102 to obtain the multimedia feature index value 102i (i.e. the first attribute data), and generates the display parameters 102r (i.e. the first display parameters) of the 1 st to the nth image frames according to the operation logic, and outputs the display parameters to the display 101. Then, the display 101 displays the image content of the corresponding image frames (1 st to nth image frames) on the screen 101a according to the received display parameters 102r.

In this embodiment, N may be greater than 10. Among the moving image information 131 provided by the multimedia signal source 130, the 1 st image frame to the nth image frame are all the image information related to racing. The scenes of each image frame are identical and the hue changes little. The display 101 may convert the image information 131 of the 1 st to nth image frames into 1 st to nth image frame images V1 to Vn as shown in fig. 5, and display the same on the screen 101 a.

Next, referring to step S42, at least one n+kth image frame is detected, and when the at least one n+kth image frame has the second attribute data, a first display parameter is output to display the n+kth image frame. Wherein K is a positive integer greater than 1. For example, in the present embodiment, K is equal to 2 (k=2), and the moving image information 131 provided by the multimedia signal source 130 is changed from the racing scene to the scene related to the forest or animal from the n+1st image frame.

At this time, the detection logic 102g in the determining device 102c of the controller 102 forcibly outputs the first display parameters (e.g. the gamma curve D1) for displaying the 1 st to N-th image frames to the display 101 for the n+1st and n+2nd image frames, and the display 101 displays the converted n+1st and n+2nd image frame images vn+1 and vn+2 on the screen by the image information 131 of the n+1st and n+2nd image frames. At this time, although the picture scene on the screen of the display 101 has been switched, the hue color of the scene is still the same as that of the racing scene.

Then referring to step S43, at least one n+k+z image frame is detected, and when the at least one n+k+z image frame has the second attribute data, at least one third display parameter is output according to the second attribute data to display the n+k+1 image frame to the n+k+z-R image frame. Wherein Z and R are positive integers greater than or equal to 1; and Z-R is a positive integer greater than or equal to 1.

In this embodiment, Z may be 3, and r may be 1 (z=4, r=1). When the video information 131 provided by the multimedia signal source 130 is analyzed and compared by the determining device 102c, the obtained multimedia feature index value 102i of the n+k+z image frame (i.e. n+6th image frame, k=2, z=4) is found to be substantially the same as or similar to the second attribute data of the n+1 image frame and the n+2 image frame. The judging means 102c may judge that the n+k+1th image frame (n+3rd image frame) to the n+k+z image frame (n+6th image frame) have the same scene as the n+1th image frame and the n+k image frame (n+2th image frame). I.e. having a scene corresponding to a forest or animal related.

However, unlike the image display method shown in fig. 1, the controller 102 does not output the second display parameter to the display 101 according to the second attribute data of the n+k+z image frame. But outputs a third display parameter (e.g., gamma curve D3) to the display 101 that is different from the first display parameter (e.g., gamma curve D1) and the second display parameter (e.g., gamma curve D2). Wherein the third display parameter may be an over-display parameter intermediate the first display parameter and the second display parameter.

For example, in the present embodiment, such an excessive display parameter may be a gamma curve D3 (as shown in fig. 5) having a waveform between the gamma curve D1 (first display parameter) and the gamma curve D2 (second display parameter). Further, the display 101 converts the image information of the n+k+1th image frame (n+3th image frame) to the n+k+z-R image frame (n+4th image frame) into the n+3 th image frame image vn+3 and the n+4th image frame image vn+4 according to the third display parameter, and displays them on the screen 101 a. The hues of the n+3-th image frame image vn+3 and the n+4-th image frame image vn+4 may be hues between the racing scene and the forest or animal related scene (as shown in fig. 5), so as to further mitigate the visual effect during the scene transition.

Subsequently, referring to step S44, a second display parameter is outputted according to the second attribute data to display the n+k+z-r+1 image frame (i.e. the n+5 image frame) to the n+k+z image frame (i.e. the n+6 image frame). The display 101 converts the image information 131 of the n+5 th image frame and the n+6 th image frame into the n+5 th image frame image vn+5 and the n+6 th image frame image vn+6 to be displayed on the screen according to the second display parameters of the n+k+z-r+1 th image frame (n+5 th image frame) to the n+k+z image frame (n+6 th image frame) so as to have the scene tone color corresponding to the forest or animal (as shown in fig. 5).

Referring to fig. 6, fig. 6 is a schematic diagram showing a series of image frame changes for performing the image display method of fig. 4 according to another embodiment of the present disclosure. FIG. 6 depicts a frame image variation substantially similar to that of FIG. 5; the difference is that the third display parameter for displaying the n+k+1th image frame (n+3rd image frame) to the n+k+z-R image frame (n+4th image frame) of fig. 6 includes a plurality of gradually changing sub-parameters interposed between the first display parameter (e.g., gamma curve D1) and the second display parameter (e.g., gamma curve D2).

In the present embodiment, the controller 102 forcibly outputs the first sub-display parameter (e.g., the gamma curve D61) and the second sub-display parameter (e.g., the gamma curves D61 and D62) to the display 101 for displaying the n+k+1th image frame (n+3th image frame) to the n+k+z-R image frame (n+4th image frame), respectively. Wherein the first sub-display parameter (gamma curve D61) is closer to the first display parameter (gamma curve D1); the second sub-display parameter (gamma curve D62) is closer to the second display parameter gamma curve D2).

By outputting the first sub-display parameters (e.g., the gamma curve D61) and the second sub-display parameters (e.g., the gamma curves D61 and D62) that gradually change to the display 101, the n+2th image frame image vn+2 (using the gamma curve D1), the n+3rd image frame image vn+3 (using the gamma curve D61), the n+4th image frame image vn+4 and (using the gamma curve D62) and the n+5th image frame image vn+5 (using the gamma curve D2) displayed on the screen 101a of the display 101 are subjected to gradual change adjustment during scene switching, so that the mosaic phenomenon and the flash effect generated during scene switching are more effectively alleviated, and the visual effect of a user is improved.

The display device 100 can be integrated with other devices to form an image display system 70 for displaying a dynamic image signal 131 including a plurality of consecutive image frames. Referring to fig. 7, fig. 7 is a block diagram illustrating a functional configuration of an image display system 70 for performing the above-mentioned image display method according to another embodiment of the present disclosure.

In this embodiment, the image display system 70 includes a cloud database 710 and another display 701 in addition to the display 100. The controller 702 may be built into the display 100 or may be provided separately. The cloud database 710 is electrically connected to the display 100 and the controller 702, and stores the dynamic image signal 131 for displaying a plurality of consecutive image frames in the display 100 and all relevant corresponding data, such as the multimedia feature index value 102i and the display parameter 102r (including the first display parameter, the second display parameter and the third display parameter) of each image frame. The display 701 is also electrically connected to the cloud database 710, and can display successive image frames of the dynamic image signal 131 on the screen 701a in synchronization with the display 100 (but not limited to the above-mentioned corresponding data).

According to the above embodiments, the present disclosure provides an image display apparatus and system and an image display method thereof, which determine a scene change in a dynamic image signal by detecting a data attribute of each image frame of the dynamic image signal, and control a display parameter outputted to a display through a controller. When scene switching occurs, corresponding display parameters of the new scene image frames are delayed to be replaced, and display parameters adopted by the old scene are still output to the image display device so as to display at least one new scene image frame at the beginning of the scene switching. And then correspondingly outputting new display parameters for the subsequent new scene image frames. By delaying the switching of the new and old display parameters, the mosaic phenomenon and the flash effect generated during the image frame scene transition of the dynamic image signal are alleviated, and the visual effect of a user is improved.

In some embodiments, in addition to delaying the switching of the new display parameter and the old display parameter, the discomfort caused by the image picture to the user when the image frame scene of the dynamic image signal is frequently switched can be further alleviated by outputting the display parameter which gradually changes in the switching process of the new display parameter and the old display parameter.

It should be noted that the disclosed embodiments do not limit the scope of the invention. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
