The specific embodiments of the present invention will be described in more detail below with reference to the schematic drawings. The advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings all adopt a very simplified form and all use non-precision ratios, and are only used to facilitate and clearly explain the purpose of the novel embodiments.

The first figure is a block diagram of a first embodiment of the light bar controller of the present invention. As shown in the figure, the light bar controller 100 is coupled to an electronic device 200 having a screen to display an image. For example, the electronic device 200 can be an electronic device with image processing capabilities such as a notebook computer, a tablet computer, a computer host (with a screen), a smart TV, a smart phone, and the like.

The light bar controller 100 has a connector 120, four light bar connectors 130, a processing unit 110, a light source module 140 and a power supply module 150. The connector 120 is configured to connect to the electronic device 200 and receive a partition gradation data S1 of the image displayed on the screen of the electronic device 200. The connector 120 can be a universal serial port (USB) or a data transfer port commonly used by other electronic devices. The partition level data S1 will be described in more detail in subsequent paragraphs.

The light bar connector 130 is used to connect the light bar and provide the electrical energy required for the light bar to emit light. In one embodiment, the user may select an addressable LED light strip or It is a color light-emitting diode strip to provide more luminous effects.

Moreover, referring to the second figure, in one embodiment, the light bar controller 100 of the present embodiment has four light bar connectors 130 for connecting and supporting up to four light bars 300a, 300b, 300c, 300d, They are respectively mounted and fixed (for example, by pasting or magnetically) around the back surface of the screen of the electronic device 200 to present a light and shadow effect corresponding to the screen image. However, the present invention is not limited to this. The light strips can be mounted at other locations of the electronic device 200, such as the edge of the screen, or other items than the electronic device 200, such as a wall or other device, depending on actual usage requirements.

Further, although the light bar controller 100 of the present invention has four light bar connectors 130 to support up to four light bars, the present invention is not limited thereto. According to the actual use requirements, the computing power of the light bar controller 100 itself, and the power supply limit of the power supply module 150 (for example, the upper limit of the driving current that can be provided, etc.), the light bar controller 100 of the present invention can also be matched with one or There are other different numbers of light bar connectors 130.

The processing unit 110 is electrically connected to the connector 120 and the light bar connector 130, and generates a light bar control signal S2 to be output to each of the light bar connectors 130 according to the partition color gradation data S1 received from the connector 120 to control the connected. The lighting mode of the light bar. Specifically, the processing unit 110 confirms the positions of the respective light-emitting elements on the connected light strips 300a, 300b, 300c, and 300d, and controls the light-emitting modes of the corresponding light-emitting elements according to the partition color scale data S1, such as brightness, color temperature, and color. Wait. For example, the processing unit 110 may sequentially number the light-emitting elements on the light bar, and according to the partition color data S1, corresponding to each number (ie, The gradation data of the position of the optical element controls the illumination mode of the corresponding illuminating element. For example, the light-emitting element on the light bar is used to extend the light and shadow effect of the screen image, or the light-emitting element on the light bar is used to adjust the white balance of the screen image.

The light source module 140 is configured to generate a light source to prompt the user whether the light bar controller 100 is connected to the electronic device 200 or has received the partition color data. Further, the processing unit 110 is electrically connected to the light source module 140 to generate a light source control signal S3 to control the light source module 140. When the processing unit 110 does not receive the partition color gradation data S1, or the processing unit 110 detects that the connector 120 is not connected to the electronic device 200, the processing unit is then according to a preset lighting mode (eg, blinking, long lighting, etc.) The light source module 140 is activated.

It should be noted that although the light bar controller 100 of the present embodiment has the light source module 140 to generate bright light as a state for prompting the user of the light bar controller 100. However, the present invention is not limited to this. In another embodiment, the light source module 140 may also be omitted to reduce the manufacturing cost.

The power supply module 150 is used to supply the electric energy required for the light bar to emit light. For example, the power supply module can be connected to the mains and converted to the DC power required to drive the light strip. Moreover, in a preferred embodiment, the power supply module can supply other electronic components in the light bar controller 100, such as the processing unit 110 and the light source module 140, in addition to the power required for the light bar. , the required electrical energy.

The third figure illustrates a first embodiment of the partitioned color gradation data of the present invention by a screen. As shown in the figure, the screen image 500 is presented on the screen, and the extension covers the entire screen. before The partition gradation data S1 corresponds to the surrounding area 520 of the screen image 500 of the electronic device. Moreover, the number of partitions of the partition level data S1 depends on the number of light-emitting elements of the light bar or the distance between the light-emitting elements. This surrounding area 520 surrounds the perimeter of the screen image 500 and has a predetermined width w. In a preferred embodiment, in order to avoid the operation time delay caused by the excessive surrounding area 520, and even affect the normal operation of the electronic device 200, the preset width w may be 15-25 image pixels.

It should be noted that the partition level data S1 is generated by the electronic device 200 instead of the processing unit 110 in the light bar controller 100. Therefore, the partition gradation data S1 is not limited by the computing power and the operation speed of the light bar controller 100, and can generate more immediate and more accurate partition gradation data S1.

Secondly, in order to make the partition gradation data S1 accurately reflect the gradation or color of the screen image 500. In a preferred embodiment, the partition gradation data S1 may be the average gradation value of the image pixels in each sub-region 522, or the area occupied by each sub-region 522 is the largest (the maximum number of image pixels) Level value. However, the present invention is not limited to this, and other calculation methods for image processing that can represent representative color gradations or colors from a certain range of screen images can also be applied to the present invention.

In addition, the processing unit 110 can directly generate the light bar control signal S2 by using the partition color gradation data S1 such that the light emitting luminance of the light emitting elements on the light bar corresponds to the color gradation of each corresponding sub-region 522. However, the present invention is not limited to this. The processing unit 110 can also generate the light bar control signal S2 by using the partition level data S1 according to a preset mode, for example, adjusting the color temperature of the light-emitting elements on the light bar by using the light bar control signal S2.

Since the light-emitting elements on the light strips 300a, 300b, 300c, and 300d are mostly equidistantly disposed, each side of the surrounding area 520 is divided into a plurality of light-emitting elements or the light-emitting element spacing on the corresponding light strips. Sub-region 522. That is to say, the peripheral areas corresponding to the upper side, the lower side, the left side, and the right side of the screen image 500 are divided into a plurality of sub-areas. In the figure, 10 sub-regions 522 are divided by taking the upper side of the screen image 500 as an example.

For example, if the number of light-emitting elements on the light bar is 10 according to the number of light-emitting elements, the width direction (ie, the direction of 1920 image pixels) is divided into 10 for a 1920×1080 screen image 500. Each sub-region 522 has a length of 192 image pixels. According to the spacing of the illuminating elements, it is assumed that the spacing of the illuminating elements on the light bar is 50 mm, and the width of the screen image 500 is 500 mm, in the case of a 1920×1080 screen image 500, the broad side direction (ie, the direction of 1920 image pixels). It will be divided into 10 sub-regions 522, and each sub-region 522 has a length of 192 image pixels.

The foregoing example illustrates the technical content of the present invention by partitioning the wide-side direction of the screen image 500. The narrow side direction of the screen image 500 can also be applied to the corresponding partition color gradation data S1, and therefore will not be described again.

The fourth figure illustrates a second embodiment of the novel partition gradation data in a screen. The screen image 600 is presented on the screen. In the embodiment of the third embodiment, the screen image 500 extends to cover the entire screen. The upper and lower sides of the screen image 600 of the embodiment have a black bar 610 (only the upper part is indicated in the figure). black side). The black border 610 usually appears when the aspect ratio of the screen is different from the aspect ratio of the image. For example, if the aspect ratio of the screen is 16:10 and the aspect ratio of the image is 16:9, a black border 610 will be generated on the upper and lower sides of the screen image 600; if the aspect ratio of the screen is 16:10 The aspect ratio of the image is 4:3, and black edges are produced on the left and right sides of the screen.

In the embodiment, when the partition color data S1 is generated, the image content of the entire screen is not directly processed, but the screen image 600 is displayed on the screen (it can also be understood as being for the image or video material presented on the screen). ) for processing. That is to say, in this embodiment, the black border 612 is excluded, and only the screen image 600 is processed. The partition level data S1 corresponds to the surrounding area 620 of the screen image 600 instead of the surrounding area of the entire screen image. This surrounding area 620 is wrapped around the screen image 600 and has a predetermined width w.

Further, each side of the surrounding area 620 is divided into a plurality of sub-areas 622 according to the number of light-emitting elements or the spacing of the light-emitting elements on the corresponding light bar. The technical features of this part are similar to the embodiment of the foregoing third figure, and are not described herein.

It should be noted that in the foregoing embodiments of the third and fourth figures, the partition level data S1 will cover all the surrounding areas 520, 620, that is, the surrounding areas 520, 620 around the screen image 500, 600 are partitioned to The partition gradation values corresponding to the respective sub-regions 522, 622 are obtained. However, the present invention is not limited to this. The partition level data S1 may also be only for a part of the surrounding area 520, 620, for example, only for the upper side of the screen image 500, 600, or only for the screen image 500, depending on the actual demand and the number or length of the light bars to be matched. The left half of 600.

The fifth figure is a block diagram of a second embodiment of the light bar controller of the present invention. The light bar controller 100' of the present embodiment is similar to the light bar controller 100 of the first figure. The main difference is that the light bar controller 100' of the embodiment further has a light detector 160 for detecting Measure the ambient brightness. The processing unit 110 is electrically connected to the photodetector 160, and adjusts the light bar control signal S2 according to the detected ambient brightness data S4.

For example, if the ambient brightness data S4 received by the processing unit 110 indicates that the light bar controller 100' is in a high-brightness environment, the processing unit 110 then moderately adjusts the brightness of the light-emitting elements on the light bar according to the ambient brightness data S4; On the other hand, if the ambient brightness data S4 received by the processing unit 110 indicates that the light bar controller 100' is in a low-brightness environment, the processing unit 110 then moderately adjusts the brightness of the light-emitting elements on the light bar according to the ambient brightness data S4.
