Central server and dramatic performance system including same
A central server according to an embodiment of the present invention may comprise a database which stores library data corresponding to a library to be executed in a lighting device, a communication unit which transmits the library data to a mobile terminal of a user, and a processor which acquires a seat layout map of a performance hall and provides directing data including information on a color pattern that each of a plurality of pixels constituting the seat layout map has to express to each pixel.
1. A central server comprising:
a database configured to store library data corresponding to a library to be executed by a lighting device;
a communication unit configured to transmit the library data to a user's mobile terminal; and
a processor configured to acquire a seat map of a performance hall and to give each of a plurality of pixels, constituting the seat map, direction data including information on a color pattern to be expressed by each of the plurality of pixels,
wherein the processor is configured to generate a dot animation that is a combination of frame images extracted from an image and to extract colors of the pixels from the generated dot animation,
wherein the processor is configured to convert the extracted colors into colors most similar to the extracted colors among 256 colors,
wherein the processor is configured to determine continuity of the converted colors and to determine whether transition of the continued colors is performed after determining the continuity of the colors,
wherein the processor is configured to determine whether transition of RGB values of the previous color and RGB values of the next color is performed using a cosine similarity technique, and
wherein the processor is configured to acquire a period in which the transition of the colors is repeatedly output and a color ratio in the period, and the color ratio indicates a ratio of a frequency of a specific color against a total frequency of the detected colors in the period.
2. The central server of claim 1 wherein the processor is configured to extract the color pattern based on the period in which the transition of the colors is repeatedly output and the color ratio.
3. The central server of claim 2 , wherein the color pattern is any one of a blink pattern, a strobe pattern, and a breath pattern.
4. The central server of claim 1 , wherein the plurality of pixels correspond to a plurality of lighting devices, respectively, each outputting a light pattern corresponding to the color pattern.
5. The central server of claim 1 , wherein the library data comprises library identification information for identifying the library, information indicating colors or brightness of light output by a light source unit, and information on a light pattern output by the light source unit.
6. The central server of claim 1 wherein the dot animation is an animation indicating light patterns to be output by a plurality of lighting devices as dots in accordance with the passage of time.
7. The central server of claim 1 , wherein the direction data includes information on a color to be expressed by a corresponding pixel, a color pattern and an output period of the color pattern.
