The color calibration system 1 includes a self-propelled colorimeter 11, a display 12 having a display screen 121 on which an image is displayed, and an information processing device 13, and an image displayed on the display screen 121 of the display 12. This system performs color calibration for color and brightness.

  First, the self-propelled colorimeter 11 will be described. FIG. 2 is a perspective view of the self-propelled colorimeter 11. FIG. 3 is a top view, a side view, and a bottom view of the self-propelled colorimeter 11. FIG. 4 is a block diagram showing the configuration of the self-propelled colorimeter 11. The self-propelled colorimeter 11 is a colorimeter for measuring the color and brightness of an image displayed on the display screen 121 of the display 12, and includes a measuring unit 111, a suction mechanism 112, a moving mechanism 113, and the like. The communication unit 114 is included.

  The suction mechanism 112 is a mechanism for sucking and holding the self-propelled colorimeter 11 on the display screen 121 of the display 12. The adsorption mechanism 112 is adsorbed by, for example, vacuum adsorption. Specifically, the suction mechanism 112 includes a cylindrical portion 112a, a fan 112b provided in the cylindrical portion 112a, and a first motor (not shown) that rotates the fan 112b, and is self-propelled by the rotation of the fan 112b. By discharging the air on the bottom surface side of the color measuring device 11 to the upper surface side, a difference in atmospheric pressure is generated and adsorbed thereby.

  The measuring unit 111 includes a light receiving unit 111 a provided in front of the moving mechanism 113 and the suction mechanism 112. In a state where the self-propelled colorimeter 11 is attracted to the display screen 121, the light receiving unit 111a faces a predetermined area of the display screen 121 and receives light from pixels in the area. The measuring unit 111 converts the amount of light received by the light receiving unit 111a into an electrical signal, and measures the color and brightness of the area facing the light receiving unit 111a. For example, the color measured by the measurement unit 111 is represented by RGB gradation values of 256 gradations. A measurement result by the measurement unit 111 is input to the communication unit 114.

  The communication unit 114 is a communication circuit for performing communication with other devices such as the information processing apparatus 13. The self-propelled colorimeter 11 is connected to the information processing apparatus 13 via a communication unit 114 so as to be communicable with a wired or wireless network. As a standard for the network connection, USB (Universal Serial Bus), Bluetooth ( Registered trademark). The self-propelled colorimeter 11 sequentially transmits the measurement result by the measurement unit 111 to the information processing device 13 or receives a command from the information processing device 13 through the communication unit 114.

  The moving mechanism 113 is a mechanism for moving on the display screen 121 in a state where the self-propelled colorimeter 11 is adsorbed to the display screen 121 by the adsorption mechanism 112. The moving mechanism 113 raises and lowers a portion other than the endless track 113a, a second motor (not shown) for driving the endless track 113a, and the cylindrical portion 112a of the self-propelled colorimeter 11 in the axial direction of the cylindrical portion 112a. And a fourth motor (not shown) for turning a portion other than the cylindrical portion 112a of the self-propelled colorimeter 11 around the axis of the cylindrical portion 112a. In the suction state, the self-propelled colorimeter 11 can move on the display screen 121 while being sucked by driving the endless track 113a by the second motor. Further, in the suction state, the self-propelled colorimeter 11 uses the third motor to raise the parts other than the cylindrical portion 112a of the self-propelled colorimeter 11 so as to be separated from the display screen 121, and the fourth motor. Thus, after rotating the portion other than the cylindrical portion 112a of the self-propelled colorimeter 11 to the right or left around the axis of the cylindrical portion 112a, the cylindrical portion of the self-propelled colorimeter 11 so as to approach the display screen 121 By lowering the part other than 112a, it is possible to turn on the spot while adsorbing. In the present embodiment, each of the motors operates according to a command from the information processing device 13.

  Next, the display 12 will be described. FIG. 5 shows the configuration of the display 12. The display 12 includes a display screen 121, a display screen control unit 122 that controls the display screen 121, and a communication unit 123 that communicates with other devices.

In the present embodiment, the display 12 has functions of a measurement position storage unit 1221, a color calibration image display control unit 1222, and a guide route display control unit 1223 in addition to the functions of a conventionally known liquid crystal display, plasma display, and the like. This is a self-propelled colorimeter-compatible display.

  The measurement position storage unit 1221 stores one or more measurement positions that are positions on the display screen 121 that the self-propelled colorimeter 11 should measure for color calibration. FIG. 6 shows an example of the measurement position. In FIG. 6, the measurement position is indicated by a reference sign “P”. The measurement position P may be two places spaced on the display screen 121 as shown in FIG. 6 (a), or may be spaced on the display screen 121 as shown in FIG. 6 (b). There may be four places, or nine places at intervals on the display screen 121 as shown in FIG. 6 (c).

  The color calibration image display control unit 1222 performs control to display an image for color calibration at the measurement position on the display screen 121. The image for color calibration is a conventionally known image, for example, a white (R: 255, G: 255, B: 255) image or a black (R: 0, G: 0, B: 0). ) Image.

  The guide route display control unit 1223 performs control to display a guide route for guiding the self-propelled colorimeter 11 to the measurement position around the measurement position on the display screen 121. FIG. 7 shows an example of the guidance route. FIG. 7 corresponds to FIG. 6B, and of the two measurement positions P below the display screen 121 shown in FIG. 6B, from the left measurement position P to the right measurement position P. A guide route R is shown. In this example, the measurement position P on the left is the start point of the self-propelled colorimeter 11, and a red image R1 is displayed. The measurement position P on the right side is the goal point of the self-propelled colorimeter 11, and a white image R2 is displayed. A blue image R3 is displayed between the start point and the goal point. In addition, a green image R4 is displayed in a portion on the left side of the blue image R3 when viewed in the direction from the start point to the goal point. Further, a purple image R5 is displayed in a portion on the right side of the blue image R3 when viewed in the direction from the start point to the goal point. A yellow image R6 is displayed on the left side of the start point and on the right side of the goal point. A guide route R is a combination of these images R1 to R6. The sizes of the images R1 and R2 are about the same as or slightly larger than the size of the light receiving unit 111a of the self-propelled colorimeter 11.

  In this example, the color of the guide route R is red, white, blue, green, purple, and yellow, but is not limited to this, and the color of the image used for color calibration and the frame of the display 12 Any color scheme may be used as long as it is different from the color and the gradation value of each color is sufficiently different (for example, if any gradation value of RGB is different by 20 or more in 256 gradations). .

Next, the information processing apparatus 13 will be described. FIG. 8 shows the configuration of the information processing apparatus 13. The information processing apparatus 13 includes a display unit 131 for displaying an image, an input unit 132 for a user to input, a communication unit 133 for communicating with other devices, a color calibration unit 1341, and a moving mechanism control. And a control unit 134 functioning as the unit 1342, and a PC (
Personal Computer).

The information processing apparatus 13 is connected to the self-propelled colorimeter 11 via a communication unit 133 so as to be communicable with a wired or wireless network.
Universal Serial Bus), Bluetooth (registered trademark), and the like. The information processing device 13 is connected to the display 12 via a communication unit 133 so that it can communicate with the display 12 via a wired or wireless network. The standards for the network connection include RS-232C, USB (Universal Serial Bus), Ethernet. (Registered trademark), HDMI (
High-definition Multimedia Interface (CEC), Consumer Electronics Control (CEC), and the like.

  The color calibration unit 1341 receives the measurement result transmitted by the communication unit 114 of the self-propelled colorimeter 11, and performs color calibration of the display 12 from the measurement result. The color calibration method may be a conventionally known method, and the image quality adjustment parameter is appropriately changed by color calibration. Examples of the image quality adjustment parameter include color temperature, contrast value, white balance, brightness value, and gamma value.

  The movement mechanism control unit 1342 controls the movement mechanism 113 so that the self-propelled colorimeter 11 moves on the guide route based on the measurement results sequentially transmitted from the self-propelled colorimeter 11. More specifically, the moving mechanism 113 is controlled so that the light receiving unit 111a of the self-propelled colorimeter 11 moves from a position facing the start point to a position facing the goal point.

  Based on the measurement result, the movement mechanism control unit 1342 causes the self-propelled colorimeter 11 to perform any one of the forward movement, the backward movement, the left turn, and the right turn. In the middle of any operation, when the measurement result changes greatly due to the movement of the self-propelled colorimeter 11, that is, when red, white, blue, green, purple, or yellow, which will be described later, changes to a different color ( For example, when any gradation value of RGB changes by 20 or more from the original color in 256 gradations), the movement mechanism control unit 1342 stops the operation, and based on the measurement result immediately after the cancellation, To do this. Below, an example of the control content of the movement mechanism control part 1342 corresponding to the guidance route shown in FIG. 7 is demonstrated for the cases (1) to (7).

(1) When the measurement result by the self-propelled colorimeter 11 is red or a color very close to it (for example, in 256 gradations, the difference between the gradation values of RGB with respect to red is less than 20). In this case, the movement mechanism control unit 1342 controls the movement mechanism 113 so that the self-propelled colorimeter 11 moves forward by a predetermined distance. However, in this case, when the operation immediately before being canceled is a backward operation, the moving mechanism control unit 1342 turns the self-propelled colorimeter 11 to a right angle or a predetermined angle (for example, 1 ° to 5 °). Turn left and then move forward a predetermined distance. The predetermined distance is set based on the size of the display 12 and is, for example, 1/10 to 1/2 of the length of the display screen 121 in the width direction.

(2) When the measurement result by the self-propelled colorimeter 11 is white or a color very close to it (for example, in 256 gradations, the difference between the gradation values of RGB with respect to white is less than 20) Since the self-propelled colorimeter 11 has arrived at the goal point where the white image R2 is displayed, the movement mechanism control unit 1342 prevents the self-propelled colorimeter 11 from performing all operations. In addition, the moving mechanism 113 is controlled. After controlling in this way, the information processing apparatus 13 transmits a command to display a color calibration image at the goal point to the color calibration image display control unit 1222 of the display 12. When the measurement result is transmitted from the self-propelled colorimeter 11 after the transmission of this command, the information processing apparatus 13 instructs the guide route display control unit 1223 of the display 12 to display the next guide route. Send.

(3) When the measurement result by the self-propelled colorimeter 11 is blue or a color very close to it (for example, in 256 gradations, the difference in RGB gradation values from blue is less than 20) The moving mechanism control unit 1342 controls the moving mechanism 113 so that the self-propelled colorimeter 11 moves forward by a predetermined distance. The predetermined distance is set based on the size of the display 12 and is, for example, 1/10 to 1/2 of the length of the display screen 121 in the width direction.

(4) When the measurement result by the self-propelled colorimeter 11 is green or a color very close to it (for example, in 256 gradations, the difference between the gradation values of RGB with respect to green is less than 20) The moving mechanism control unit 1342 controls the moving mechanism 113 so that the self-propelled colorimeter 11 turns to the right.

(5) When the measurement result by the self-propelled colorimeter 11 is purple or a color very close to it (for example, in 256 gradations, the difference between the gradation values of RGB and purple is less than 20) The moving mechanism control unit 1342 controls the moving mechanism 113 so that the self-propelled colorimeter 11 turns counterclockwise.

(6) When the measurement result by the self-propelled colorimeter 11 is yellow or a color very close to it (for example, in 256 gradations, the difference in RGB gradation values from yellow is less than 20) The moving mechanism control unit 1342 controls the moving mechanism 113 so that the self-propelled colorimeter 11 moves backward by a predetermined distance. The predetermined distance in this case is shorter than the predetermined distance when moving forward, and is, for example, 1/10 to 1/2 of the predetermined distance when moving forward.

(7) When the measurement result by the self-propelled colorimeter 11 is a color (other color) other than red, white, blue, green, purple, and yellow, ie, other than (1) to (6) In this case, the movement mechanism control unit 1342 controls the movement mechanism 113 so that the self-propelled colorimeter 11 performs the same operation as that performed immediately before the movement is stopped. For example, if the measurement result at a certain time is green and the self-propelled colorimeter 11 turns right based on the measurement result, and the measurement result changes to another color due to the right turn, the measurement is stopped. Since the immediately preceding operation is a right turn, the movement mechanism control unit 1342 controls the movement mechanism 113 so that the self-propelled colorimeter 11 turns right.

  Note that the movement mechanism control unit 1342 moves so that the self-propelled colorimeter 11 does not perform all operations in the cases (2) to (6) and when there is no operation immediately before being canceled. The mechanism 113 is controlled. In this case, since the self-propelled colorimeter 11 has not been installed at the start point where the red image R1 is displayed, the information processing apparatus 13 has an error in the installation location of the self-propelled colorimeter 11. The display unit 131 notifies the person who performs color calibration that the self-propelled colorimeter 11 should be installed at the correct installation location.

  The movement mechanism control unit 1342 calculates the elapsed time from the start of color calibration and the movement distance of the self-propelled colorimeter 11, and the self-propelled colorimeter 11 reaches the goal point within a predetermined target time. The moving mechanism 113 prevents the self-propelled colorimeter 11 from performing all operations when it has not reached or when the self-propelled colorimeter 11 has moved a distance greater than a predetermined target distance. To control. After controlling in this way, the information processing apparatus 13 informs the person who performs color calibration by the display unit 131 that the self-propelled colorimeter 11 should be installed again at the correct installation location. . Note that the target time is set based on the size of the display 12 input via the input unit 132 and the moving speed of the self-propelled colorimeter 11. The target distance is set based on the size of the display 12 input via the input unit 132.

  In the present embodiment, the measurement position, the image for color calibration, and the guide route are stored in the display 12, but in another embodiment of the present invention, these are stored in the information processing device 13 instead of the display 12. And the information processing device 13 may have the functions of the measurement position storage unit 1221, the color calibration image display control unit 1222, and the guidance route display control unit 1223. In this case, as the display 12, a display known in the art that is not compatible with the self-propelled colorimeter 11 can be used instead of the self-propelled colorimeter-compatible display.

  Further, as another embodiment of the present invention, the display 12 and the information processing apparatus 13 may be integrated. In this case, the display 12 can perform its own color calibration.

  Further, as another embodiment of the present invention, the self-propelled colorimeter 11 and the information processing apparatus 13 may be integrated. In this case, the self-propelled colorimeter 11 can move by controlling the moving mechanism 113 by itself.

  In step A1, an image Q1 for color calibration is displayed at the measurement position on the lower left of the display screen 121 according to a command from the information processing apparatus 13. After displaying the image Q1, the person who performs color calibration installs the self-propelled colorimeter 11 so that the light receiving unit 111a faces the image Q1. At this time, the self-propelled colorimeter 11 is attracted to the display screen 121 by the adsorption mechanism 112.

  In step A <b> 2, the measurement result at the lower left measurement position on the display screen 121 is transmitted from the self-propelled colorimeter 11 to the information processing device 13. In step A3, according to the instruction of the information processing device 13 that has received the measurement result, a guide route T1 is displayed with the measurement position at the lower left of the display screen 121 as the start point and the measurement position at the lower right of the display screen 121 as the goal point. The In step A4, the self-propelled colorimeter 11 moves from the lower left start point of the display screen 121 to the lower right goal point of the display screen 121 in accordance with an instruction of the information processing device 13 based on the measurement result.

In step A <b> 14, the measurement result at the measurement position at the upper left of the display screen 121 is transmitted from the self-propelled colorimeter 11 to the information processing apparatus 13. In step A15, the information processing apparatus 13 performs color calibration by changing the image quality adjustment parameters of the display 12 based on the measurement results at the four measurement positions.

  In this way, the person who performs color calibration simply installs the self-propelled colorimeter 11 at the measurement position at the lower left of the display screen 121. Thereafter, the person who performs color calibration does not perform any operation. The color calibration system 1 automatically measures the color and brightness at the measurement position and performs color calibration. Therefore, according to the color calibration system 1, color calibration can be easily performed.
