Please refer to FIGS. 1A, 1B, 2, and 3, and FIG. 1A is a schematic diagram of an electronic device 100 according to an embodiment of the present invention. FIG. 1B is a flowchart 150 of a method for displaying a dynamic tablecloth according to an embodiment of the present invention. FIG. 2 is a schematic diagram of layers L1 L L2 of a dynamic tablecloth of an electronic device 100 according to an embodiment of the present invention. FIG. 3 is a schematic diagram of layers L1 LLn of a dynamic tablecloth of an electronic device 100 according to an embodiment of the present invention.

In an embodiment, the electronic device 100 can be a mobile phone, a tablet, or other device having a display function.

In one embodiment, the electronic device 100 includes a sensor 10, a processor 20, a storage device 30, and a display 50.

In an embodiment, the sensor 10 is configured to sense an interactive information. The sensor 10 is, for example, a gyroscope, a gravity sensor, an acceleration sensor, an eye tracker, a touch sensor, and/or a timer.

In one embodiment, the storage device 30 can be used to store a plurality of images and/or layers L1 L Ln (as shown in FIG. 3). In an embodiment, as shown in FIG. 2, such static layers are, for example, layer L1 and layer L2. The storage device 30 can be implemented by a device such as a memory, a hard disk, a flash memory card, or the like.

In the following embodiments, for convenience of description, the layer L1 and the layer L2 are taken as an example for illustration. It should be noted that the static layer described in this case is not limited to only the layer L1 and the layer L2. As shown in FIG. 3, the static layer group described in the present invention may also include multiple layers L1~Ln to process the multi-layer layer. The manner of L1~Ln can be the same as the way of processing the first layer L1 and the second layer L2.

In one embodiment, the processor 20 can be a micro control unit, a microprocessor, a digital signal processor, an application specific integrated circuit (ASIC), or a logic. The circuit is implemented.

In an embodiment, please refer to FIG. 1B, and a flow chart 150 of the method for displaying the dynamic tablecloth of the present invention will be described in detail below. In some embodiments, the following process may be implemented by a non-transitory computer readable recording medium. The non-transitory computer readable recording medium records at least one program instruction, and the at least one program instruction is loaded. After an electronic device, perform the following steps.

In step 151, the storage device 30 is configured to provide a plurality of images.

In step 153, the processor 20 applies a layer blending mode to each of the images to generate a corresponding layer.

In an embodiment, the layer blending mode may be a normal mode, a dissolve mode, a darkening mode, a color value-adding mode, a deepening color mode, a linear deepening mode, a color darkening mode, a brightening mode, a color filter mode, Highlight color mode, linear highlighting - increasing mode, color brightening mode, overlay mode, soft light mode, hue mode, solid light mode, intense light source mode, linear light source mode, small light source mode, solid color overprint mixing mode, difference Mode, Exclusion Mode, Subtract Mode, Split Mode, Saturation Mode, Color Mode, Lightness Mode, etc. These layer blend modes each have different characteristics. For example, the filter mode preserves the white portion of the layer. The black part of the layer is converted to be fully transparent, and the gray part of the layer is converted to semi-transparent. The degree of translucency varies depending on whether the gray is black or white.

Please refer to FIG. 1B~2. In an embodiment, the second image is applied with the overlay mode to generate the layer L2, and the first image is applied by the normal mode to generate the layer L1, but is not limited thereto.

Moreover, in some embodiments, the layers comprise a background layer, and other of the layers are layered on the background layer, and the layer blending mode of the background layer is designated as the normal mode.

In step 155, the processor 20 superimposes the layers to produce a superimposed image.

In an embodiment, as shown in FIG. 2, the layer L1 is located below the layer L2, and the processor 20 superimposes the layers L1 and L2 to generate a superimposed image.

In one embodiment, as shown in FIG. 2, the area of the layer L2 is larger than the display screen area of the display 50, and the visible range Ra in the layer L2 corresponds to the overall display screen of the display 50.

In an embodiment, please refer to FIG. 4A to FIG. 4C. FIG. 4A to FIG. 4C are schematic diagrams showing a method for generating a dynamic tablecloth according to an embodiment of the present invention. In FIG. 4A, the layer L2 is assigned a layer blending mode as an overlay mode. The overlay mode is characterized by retaining or enhancing the bright and dark sides of the image, and the proportion of each color in the layer L2 is not The same, so the coverage mode can be used to adjust the brightness of each block in layer L2.

For example, if the second image has a gray block in the process of applying the overlay mode to generate the layer L2 (for example, each RGB value in the pixel is 128), the processor 20 will The gray block in the second image is transparently presented; when the block in the second image has RGB values higher than 128 in the pixel, the processor 20 applies the color filter effect in the overlay mode to the block. Brightening the image of the block; when the second image has a block in which the RGB values in the pixel are all lower than 128, the processor 20 applies the color increment effect in the overlay mode to the block. The image of this block is darkened; accordingly, the result of the second image undergoing such adjustment is layer L2. Among them, the color filter effect and the color value-adding effect in the overlay mode are twice the intensity of the color filter mode and the color value-add mode in the layer blend mode, and therefore, the characteristics of the overlay mode are suitable for the performance of light.

On the other hand, in FIG. 4B, the layer L1 is, for example, a radially concentric circular path, the layer L1 is set as the background image layer, and the layer blending mode designates the layer L1 as the normal mode (Normal) without any Adjustment.

As shown in FIG. 4C, when the layer L2 overlaps with the layer L1, a superimposed image DW is generated, and the superimposed image DW is very intense in contrast.

It should be noted that the present invention is not limited to the above, the layer blending mode of the layer L2 is specified as the overlay mode and the layer blending mode of the layer L1 is designated as the normal mode, and the layer L1 and the layer L2 may also be designated as other layers in the layer blending mode. mode. Therefore, when the layer L1 is superimposed with the layer L2 that is applied in a different layer blending mode, a superimposed image of different visual effects is generated.

In step 157, the processor 20 receives an interactive message. The interactive information can be transmitted to the processor 20 after being sensed by the sensor 10.

In an embodiment, the sensor 10 may be a gyroscope, and the interactive information may refer to a radian value sensed by the gyroscope when the user moves the electronic device 100. In some embodiments, the interactive information may refer to information sensed by the sensor 10 when the user interacts with the electronic device 100.

In addition, the processor 20 can set the movement rules of each layer to achieve the dynamic effect of the dynamic tablecloth.

In step 159, the processor 20 changes the color effect of the superimposed image according to the interactive information to generate a dynamic tablecloth.

For example, when the electronic device 100 is moved, the layer L2 is displaced in a rotating manner, and the layer L1 is fixed at a fixed point. Thereby, the layer L2 rotated as the electronic device 100 is moved and the fixed layer L1 are superimposed to generate different superimposed images, and different superimposed images are displayed through the display 50 to present the visual feeling of the dynamic tablecloth.

Hereinafter, in order to make the description more specific, the sensor 10 is taken as an example of the implementation of the gyroscope to illustrate the specific implementation of the interaction between the sensor 10 and the dynamic tablecloth.

In one embodiment, the gyroscope is configured to sense a radian value and transmit the radian value and the preset displacement coefficient to the processor 20. Among them, the interactive information contains the radians value.

In an embodiment, as shown in FIG. 2, when the electronic device 100 is moved (for example, rotated in the direction a of the YZ plane or rotated in the direction b of the XZ plane), the gyroscope senses the curvature of the electronic device 100 being moved. The value is passed to the processor 20 for the sensed radians value. Then, the processor 20 obtains a layer translation operation mode according to the radians value through a translation function, and changes the color effect of the superimposed image according to the layer translation operation mode, and the translation function is: T=G( Gyro ^x )* ,, 0.1≦α≦0.9 among them, Wherein, the symbol T represents a translational operation mode, the symbol Gyro ^x represents a radii value of the X-axis sensed by the gyroscope (for example, positive 60 degrees or minus 60 degrees), and the symbol α is a preset displacement coefficient of the X-axis (preset displacement) The coefficient can be a preset value given by the application development side). In an embodiment, the value of the symbol Gyro ^x can be obtained by measuring the gyroscope.

It can be seen from the above translation function that if the symbol Gyro ^x is 1, and the preset symbol α value is 0.2, the symbol T is 0.2, which means that the amplitude of the layer to be translated is relatively small, for example, the processor 20 will layer according to the layer translation operation mode. L moves corresponding to the translation direction (for example, the translation direction A or the translation direction B in FIG. 2), for example, shifts 20 pixels to the right in the translation direction A, thereby changing the color content presented by the visible range Ra of the layer L2, Further, the color effect of the superimposed image generated by superimposing the layer L1 and the layer L2 is changed to present different visual effects. On the other hand, layer L1 can be set to not be adjusted or can be set to adjust according to the layer panning mode of operation.

In another example, if the symbol Gyro ^x is 1, and the preset symbol α is 0.8, the symbol T is 0.8, which means that the amplitude of the layer to be translated is relatively large. For example, the processor 20 will layer L2 according to the layer translation operation mode. Moving corresponding to the translation direction, for example, shifting 150 pixels to the right in the translation direction A, thereby changing the color content presented by the visible range Ra of the layer L2, thereby superimposing the superimposed image generated by the layer L1 and the layer L2 The color effect changes. In one embodiment, the color effect is a hue, a color saturation, a chroma, a transparency, or a brightness, but is not limited thereto.

Therefore, when the electronic device 100 is moved, the color effect (ie, visual effect) of the superimposed image also changes with the degree of movement.

In an embodiment, as shown in FIG. 2, when the electronic device 100 is moved (for example, rotated in the direction a of the YZ plane or rotated in the direction b of the XZ plane), the gyroscope senses the curvature of the electronic device 100 being rotated. The value is passed to the processor 20 for the sensed radians value. Then, the processor 20 is further configured to apply a rotation function according to the radians value to obtain a layer rotation operation mode, and change the color effect of the superimposed image according to the layer rotation operation mode, and the rotation function is: R=G( Gyro ^x ) * α+G( Gyro ^y )* β,α>0,β>0

among them, Wherein, the symbol R represents a rotational operation mode, the symbol Gyro ^x represents the radians of the X-axis sensed by the gyroscope, the symbol Gyro ^y represents the radians of the Y-axis sensed by the gyroscope, and the symbol α is the preset displacement of the X-axis. The coefficient, β is the preset displacement coefficient of the Y-axis.

In an embodiment, please refer to FIGS. 5A-5C, and FIGS. 5A-5C are schematic diagrams showing the rotation direction of an electronic device 100 according to an embodiment of the present invention. In FIG. 5A, the user rotates the electronic device 100 along the direction R1. In FIG. 5B, the user rotates the electronic device 100. In FIG. 5C, the user places the electronic device 100 along the direction R2. Make a rotation.

For example, please refer to FIG. 4C and FIG. 6A to FIG. 6C. FIG. 6A to FIG. 6C are schematic diagrams of a dynamic tablecloth according to an embodiment of the present invention. Taking the superimposed image DW in FIG. 4C as an example, the superimposed image DW is a visual effect presented by superimposing the layer L1 and the layer L2.

As shown in FIG. 6B, FIG. 6B is a visual effect of the superimposed image DW being presented by the display 50 of the electronic device 100 in the case where the electronic device 100 is not rotated.

Referring to FIGS. 6A-6C, when the electronic device 100 rotates in the direction R1 or the direction R2, the processor 20 obtains the layer rotation operation mode according to the rotation function described above, and changes the superposition according to the layer rotation operation mode. The color effect of the image. In one embodiment, processor 20 adjusts the extent of rotation of the layer based on the magnitude of the value of the layer rotation mode of operation. Referring to FIG. 2, when the value of the layer rotation operation mode is large, the layer L2 is largely rotated in accordance with the rotation direction C. On the other hand, the layer L1 can be set so as not to be adjusted or can be set to be rotated substantially according to the value of the rotational operation mode. In this way, the color effect of the superimposed image generated by superimposing the layer L1 and the layer L2 is changed.

In step 160, display 50 displays a live wallpaper.

Thereby, when the electronic device 100 is rotated, the processor 20 can change the color effect of the superimposed image according to the rotation operation mode, so that the display 50 can display the dynamic tablecloth.

It can be seen from the above that the present invention utilizes the characteristics of the layer blending mode of each layer (as shown in layers L1 to L2), so that the superimposed image of the stacked image can be expanded into a multi-dimensional visual style, for example, presenting the superb appearance process of the electronic device 100. The design (for example, the hardware appearance of the electronic device 100 is a concentric circle), and the value of the layer rotation operation mode and/or the value of the layer translation operation mode is obtained by the mobile electronic device 100 to change the color effect of the superimposed image, thereby achieving dynamic The effect of the tablecloth.

In another embodiment, please refer to FIGS. 7A-7C, 8A-8C, and FIGS. 7A-7C are schematic diagrams of a method for generating a dynamic tablecloth according to an embodiment of the present invention. 8A-8C are schematic views of a dynamic tablecloth according to an embodiment of the present invention. As shown in FIG. 7A, the layer L2 is a mixed layer, and the layer blending mode of the layer L2 is designated as a Hard Mix mode. As shown in Fig. 7B, the layer L1 is designated as the normal mode. As shown in FIG. 7C, the color effect of the superimposed image DW generated after the layer L1 and the layer L2 are superimposed. The following is further illustrated by the color effect of the superimposed image DW shown in FIG. 7C, since the layer blending mode of the layer L2 is a solid color overprinting blending mode, and the solid color overprinting blending mode is characterized in that it will overlap each other. The R value, G value, and B value of each corresponding pixel of the layer are added separately. If the total result is greater than or equal to 255, the value is directly changed to 255. If the total value is less than 255, the value is directly changed to 0. That is, the R value (red color version value) in the pixel of the layer L2 is added to the R value in the pixel of the corresponding layer L1, the G value (green color version value) in the pixel of the layer L2 and the corresponding The G values in the pixels of the layer L1 are added, and the B value (blue color plate value) in the pixel of the layer L2 is added to the B value in the pixel of the corresponding layer L1, and the total value of R and the total value of G are obtained. And B total value of three total results, the total result is greater than or equal to 255 will be directly set to 255, the total result is less than 255 will be directly set to 0, so the layer L1 is the stack generated after the layer L2 overlap The RGB values in each pixel of the image DW will only be 0 or 255, and the combination of RGB values of 0 or 225 will produce colors of red, green, blue, yellow, cyan, magenta, white, and black. Eight colors, so the superimposed image DW will contain at least one of the eight colors.

As shown in FIG. 8B, FIG. 8B is a visual effect of the superimposed image DW being presented by the display 50 of the electronic device 100 in the case where the electronic device 100 is not rotated.

As shown in FIGS. 8A and 8C, when the electronic device 100 rotates in the direction R1 or the direction R2, the processor 20 obtains the layer translation operation mode according to the above-mentioned translation function, and changes the superimposed image DW according to the layer translation operation mode. Color effect.

In other embodiments, the processor 20 changes the color effect of the superimposed image DW according to the layer rotation operation mode, so that the objects in the dynamic tablecloth are presented in a three-dimensional perspective. For example, when the electronic device 100 rotates in the direction R1 or the direction R2, the object in the dynamic tablecloth also adjusts the degree of deformation along with the value of the layer rotation operation mode, thereby realizing the visual effect of the three-dimensional image.

In one embodiment, when the sensor 10 is an eye tracker, the position of the user's eyeball to watch the dynamic tablecloth is a kind of interactive information, so that the processor 20 can watch the dynamic tablecloth according to the user's eyeball. Position to change the color effect of the superimposed image to present a dynamic effect that interacts with the user. For example, an object or light effect is produced at a position where the user's eyeball views the dynamic tablecloth.

In one embodiment, when the sensor 10 is a touch sensor, the sensor senses that the position touched by the user on the display 50 is one of interactive information, and the processor 20 can be based on the display. The color effect of the superimposed image is changed by the position touched by the user on the 50. For example, the dynamic tablecloth generates objects or light effects at the touched position, or produces different visual effects according to different touch gestures.

In one embodiment, when the sensor 10 is a timer, the time information obtained by the timer is a kind of interactive information, and the processor 20 can change the color effect of the superimposed image according to the time information. In this way, the dynamic wallpaper will show the visual effect of daytime gradual to nighttime as time goes by.

It can be seen from the above that each layer described in the present invention can select a layer blending mode to be used, and the number of layers and the size of the layer are not limited, thereby causing the layers to be superimposed to produce different color effects. In addition, the layer and the layer interact with each other, so the result of superimposing the double layer (for example, shown in Figures 4A to 4C) and the composite layer (for example, as shown in Fig. 3) will be different.

In summary, the case is based on the interactive information and the layer blending mode of each layer. By shifting the color of the layer or the transition layer, the superimposed image produced by the lamination of the layers has various changes, thereby achieving dynamic effects and imaginary physical reactions. In addition, the layer used in this case can be a static picture, which has the advantages of not occupying memory, saving efficiency, and not consuming power.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present case. Anyone skilled in the art can make various changes and refinements without departing from the spirit and scope of the present case. The scope defined in the patent application is subject to change.
