(Embodiment 1)
[1-1. Configuration of image projection system]
First, the configuration of the video projection system according to this embodiment will be explained with reference to FIGS. 1 to 7.

FIG. 1 is a diagram showing an example of use of the video projection system 1 according to the first embodiment. FIG. 2 is a schematic diagram showing the image projection system 1. As shown in FIG. Note that in addition to the video projection system 1, an operating device 10 is also shown in FIGS. 1 and 2.

As shown in FIG. 1, a video projection system 1 is a system that projects video (images) for performing on a stage, a studio, or the like. The operating device 10 is a device for operating the image projection system 1. For example, the video projection system 1 is installed on the ceiling of a stage, and the operating device 10 is placed in a light control room or a projection room in a location different from the stage.

As shown in FIG. 2, the video projection system 1 includes a video generation section 20 and a projection section 30. The video generation section 20 is connected to the operating device 10 via Ethernet (registered trademark) N. Further, the video generation section 20 and the projection section 30 are connected to each other by a communication cable 40 such as an HDMI (registered trademark: High Definition Multimedia Interface) cable. The projection section 30 is provided in a first casing 51 , and the video generation section 20 is provided in a second casing 52 that is different from the first casing 51 .

The operating device 10 is a device that operates the aspect of an image projected by the video projection system 1. The operating device 10 is, for example, a light control console configured with a personal computer, and has a display input section 11 such as a touch panel. The display input unit 11 displays an operation bar (slider) for adjusting the position, color, brightness, etc. of the image, which is an example of the aspect of the image. The operating device 10 timely transmits an illumination control signal s1, which is a signal for adjusting the image, to the image projection system 1 in response to a user's operation input using the operating bar.

The lighting control signal s1 is, for example, a standardized DMX (registered trademark: Digital Multiple X) signal. The illumination control signal s1 includes control parameters for changing the image, such as the projection position, brightness, and color of the image.

The video generation section 20 edits the image data based on the illumination control signal s1 transmitted from the operating device 10, and outputs a video signal s2 including the edited image data to the projection section 30. The video generation unit 20 will be described later.

The projection unit 30 is a projection device that projects a video (image) onto a projection target. The projection unit 30 is, for example, a projector, and includes a light source such as a semiconductor laser or a lamp, an optical system such as a lens or mirror, a display element such as a liquid crystal panel, and a projection lens. When the video signal s2 is input to the projection unit 30, an image corresponding to the video signal s2 is projected onto the projection target. In FIG. 2, the image is projected onto the floor of the building, but the projection target is not limited to the floor, but may be a wall or screen, a structure such as furniture, or an animal or plant.

As shown in FIG. 2, the projection unit 30 has a rectangular projectable area Z1. Note that the projectable area Z1 is not limited to a rectangular shape, but may be circular or polygonal, or may be omnidirectional at 360°.

The projection unit 30 projects the image M1 within a projectable region Z1, which is a projectable range, based on the video signal s2 output from the video generation unit 20. The image M1 is located within the projectable area Z1 without going outside the projectable area Z1. The image M1 moves within the projectable area Z1 and changes its color, brightness, etc. based on the video signal s2. By projecting the image M1 using the video projection system 1 in this manner, it is possible to create a state as if illumination light is being radiated from a lighting fixture such as a moving light.

FIG. 3 is a block diagram showing the video projection system 1 and the video generation unit 20 included in the video projection system 1.

As shown in FIG. 3, the video generation section 20 includes a reception section 21, a storage section 22, an editing section 23, and an output section 24. The video generation unit 20 is a processing device that performs various calculation processes, and is configured by a microprocessor and memory.

FIG. 4 is a diagram showing image data processed by the video generation section 20 and an image M1 projected from the projection section 30.

(a) of FIG. 4 shows image data d0 and d1 before editing, (b) shows image M1 before editing, and (c) shows image data d0 and d1 after editing. , (d) shows the edited image M1. Although the image data d0 and d1 are digital data, they are shown in figures for easy understanding.

The storage unit 22 stores image data d0 and d1 shown in FIG. 4(a). The image data d0 is base data corresponding to the projectable area Z1. Although the image data d0 does not have feature data such as color, brightness, and pattern, it may have the same color, brightness, and pattern as the base material of the projection target depending on the case. The image data d1 is pattern image data having a pattern corresponding to the image M1 (see (b) of FIG. 4) projected from the projection unit 30. The image data d1 exists within the image data d0, that is, within the projectable area Z1, and is superimposed on the image data d0. The image data d1 is set to predetermined data when the video projection system 1 is started.

The receiving unit 21 receives the lighting control signal s1 transmitted from the operating device 10. This illumination control signal s1 includes information regarding the control parameters of the image data d1.

The editing unit 23 edits the image data d1 by changing the control parameters of the image data d1 based on the illumination control signal s1, thereby generating edited image data d1 (see (c) in FIG. 4). Furthermore, the editing unit 23 causes the storage unit 22 to store the edited image data d1. The edited image data d1 stored in the storage unit 22 is used as original image data (unedited image data d1) when generating the next edited image data d1.

The output unit 24 outputs the video signal s2 including the edited image data d1 to the projection unit 30. The video signal s2 is, for example, a standardized HDMI (registered trademark: High Definition Multimedia Interface) signal. Based on this video signal s2, the projection unit 30 projects the edited image M1 (see (d) in FIG. 4) into the projectable area Z1. In this video projection system 1, by sequentially projecting the unedited image M1 and the edited image M1 in this way, it is possible to easily create a state in which the illumination light changes.

Here, as another example of the video projection system 1, an example in which a plurality of images M1, M2, M3, and M4 are projected using the video projection system 1 will be described.

FIG. 5 is a diagram showing an example of images M1 to M4 projected from the projection unit 30 of the video projection system 1. FIG. 6 is a diagram schematically showing how the image data d1, d2, d3, and d4 are edited in the video generation section 20. FIG. 7 is a diagram showing control parameters for image data d1 to d4 processed by the video generation section 20.

FIG. 5 shows an image M1 consisting of a small circle, an image M2 consisting of a semicircle, an image M3 consisting of a spiral shape, and an image M4 consisting of a plurality of circles.

FIG. 6(a) shows image data d0 to d4 stored in the storage unit 22. The image data d0 is base data corresponding to the projectable area Z1, and the image data d1 to d4 are pattern data corresponding to the images M1 to M4 on a one-to-one basis. Note that the storage unit 22 stores the current control parameters of each of the image data d0 to d4 and the identification address of each of the image data d0 to d4 in association with each other.

The control parameters of each image data d0 to d4 are changed by each control parameter p0, p1, p2, p3, p4 included in the illumination control signal s1. The illumination control signal s1 includes the address of each image data d0 to d4 and information regarding the changed control parameters p0 to p4. This allows the editing unit 23 to edit each image data d0 to d4 and each control parameter p0 to p4 in a one-to-one correspondence.

Each control parameter p0 to p4 is defined by the DMX (registered trademark) standard. Specifically, the control parameters p0 to p4 are Dimmer (brightness), Position, Gobo (pattern), Colour, Beam (flashing), Focus (sharpness), and Control (shown in FIG. 7). Control), Shaper, etc. are defined. Note that since the image data d0 is base data, control parameters such as color, brightness, pattern, etc. do not need to be changed.

As shown in FIG. 6(b), the editing unit 23 changes the control parameters of each of the image data d0 to d4 based on the control parameters p0 to p4 included in the illumination control signal s1. Thereby, the editing unit 23 edits each of the image data d0 to d4, and generates each of the edited image data d0 to d4. Thereafter, the editing unit 23 synthesizes the edited image data d0 to d4 to create one piece of composite image data c1, as shown in FIG. 6(c). Thereafter, every time the lighting control signal s1 is received, the editing section 23 sequentially creates composite image data c2 and c3.

The output unit 24 outputs a video signal s2 including these composite image data c1 to c3 in order to the projection unit 30. Thereby, the image projection system 1 can easily generate and project images.
