The image pickup unit 23 is attached to the upper outer side of the display unit 4 and can take an image of an object facing the display unit 4.

When the light emitting unit 24 illuminates the user U, the light emitting control device 20 functions as an illuminated mirror. Further, the light emitting unit 24 adjusts the light emitting intensity in the light emitting control process described later. The light emitting portions 24 are arranged on both sides of the mirror portion 22 in the standing direction along the sides of the mirror portion 22. The arrangement of the light emitting unit 24 is not limited to this, and may be arranged so as to surround all sides of the mirror unit 22, for example.

[Operation overview]
Next, prior to the description of the functional block included in the light emission control device 20 and the communication terminal 10, the operation outline of the present embodiment will be described.
First, with reference to FIG. 3, the premise problems will be described. FIG. 3 is a graph showing the reflectance of the mirror unit 22 of the light emission control device 20. The horizontal axis of FIG. 3 indicates the wavelength of the light incident on the mirror unit 22, and the vertical axis indicates the reflectance of the mirror unit 22 according to the wavelength. Since the mirror unit 22 is a half mirror as described above, the reflectance may be biased as compared with a general mirror. For example, the reflectance of light depends on the coating material of the reflective film.
In this example, the reflectance when light having a wavelength of 380 [nm] to 750 [nm], which is generally regarded as a visible light region, is incident on the mirror unit 22 is shown. As shown, the reflectance of purple light with wavelengths from 380 [nm] to 450 [nm] is significantly lower, and the reflectance of red light with wavelengths from 620 [nm] to 750 [nm] is also relative. Low to.

Further, even when the mirror unit 22 is realized by a half mirror having characteristics different from those of this example, there may be a problem that the reproducibility of other specific colors is lowered depending on the characteristics. Therefore, in the present embodiment, color correction is performed in order to eliminate such a decrease in color reproducibility. Specifically, in the light emission control process described later, color correction is performed by increasing the light emission intensity of the light emitting unit 24 with respect to purple and red having low color reproducibility.

In the used state, the display unit 11 of the communication terminal 10 is arranged so as to face the mirror unit 22. The light of each color of the color palette image of the display unit 11 is reflected by the mirror unit 22 and incident on the camera 12. The incident light of each color is imaged by an image sensor (not shown) of the camera 12, and then photoelectrically converted and stored as image data. The image data is transmitted to the light emission control device 20 by the transmission process described later, and the light emission control device 20 performs color correction based on the transmitted image data.

[Operation of communication terminal]
Next, the operation of the communication terminal 10 will be described. The communication terminal 10 mainly performs transmission processing.
In the transmission process, the image captured by the communication terminal 10 is repeatedly transmitted from the communication terminal 10 to the light emission control device 20.

The transmission process may be automatically executed by a predetermined application or may be manually performed by the user U. When the transmission process is performed by a predetermined application, the user U acquires, for example, application software for performing the transmission process from an application distribution server included in a server group (not shown), and operates the application software.

FIG. 9 is a flowchart illustrating a flow of transmission processing executed by the communication terminal 10.

In step S11, the color palette image is displayed on the display unit 11 of the communication terminal 10. When the color palette image is displayed, the camera 12 is activated in step S12. In step S13, a voice such as "Please turn the screen toward the light emission control device 20" is output from the output unit 37.

When the user U faces the display unit 11 on which the color palette image is displayed to the mirror unit 22 of the light emission control device 20, the color palette image is projected on the mirror unit 22 of the light emission control device 20. In step S14, the captured image analysis unit 311 performs a color palette image detection operation. The detection operation is repeated until a color palette image is detected.

The notification unit 312 may display a message or the like indicating that the transfer is completed to the display unit 11 instead of the voice.

As described above, the transmission process is completed by the series of processes of steps S11 to S18.

[Operation of light emission control device]
FIG. 10 is a flowchart illustrating a flow of light emission control processing executed by the light emission control device 20.

In step S21, the communication unit 71 waits for reception of image data from the communication terminal 10. In step S22, it is determined whether or not the image data has been received, and if the image data is not received, the process of step S21 is repeated until the image data is received. If it is determined in step S22 that the image data has been received, the process proceeds to step S23.

The received image analysis unit 612 analyzes whether or not the image data includes a color palette image by using a technique such as pattern matching or edge detection. When the analysis is completed, it is determined in step S24 whether or not the color palette image is detected. When the color palette image is not detected, an error is displayed on the display unit 219 in step S25.

When the color palette image is detected in step S24, the process proceeds to step S26. In step S26, the image comparison unit 613 performs a color comparison between the color palette image detected from the image data received from the communication terminal 10 and the color palette image of the reference color pre-recorded in the light emission control device 20. .. The color comparison is performed for each of the R, G, and B colors, as will be described in detail later.

When the process of step S25 or step S26 is completed, it is determined in step S27 whether or not the end condition is satisfied. The end condition may be the number of repetitions, and when the color comparison is performed a predetermined number of times, it is determined that the end condition is satisfied.

The method for determining the emission level of each color of the LED will be described in detail below.

[Color comparison]
FIG. 11 is a diagram showing a color palette image displayed on the display unit 11 of the communication terminal 10 in step S11. The color palette image 13 includes a red region C1, a green region C2, a blue region C3, a white region C4, and a code region 15. The color regions C1 to C4 are, for example, rectangles having a long side in the longitudinal direction of the display unit 11 and are displayed adjacent to each other. The code region 15 is arranged above a region different from the color regions C1 to C4 of the color palette image 13, for example, the color regions C1 to C4. In the code area 15, for example, a QR code (registered trademark) (Quick Response Code) is displayed.

In step S23, the color palette image 13 received from the communication terminal 10 is analyzed. At this time, the received image analysis unit 612 may read the code in the code area 15. The code region 15 plays an auxiliary role for the received image analysis unit 612 to detect the color regions C1 to C4 of the color palette. For example, when the QR code (registered trademark) of the code region 15 is detected, the range of each color region of the color regions C1 to C4 is immediately specified, and the detection of the color regions C1 to C4 can be ensured. ..

FIG. 12 is a diagram showing the emission intensity of the color palette image 13 displayed on the communication terminal 10 for each color. The emission intensities of the red region C1, the green region C2, the blue region C3, and the white region C4 are all 255. In the present embodiment, as an example, the emission intensity is represented by 256 steps from 0 to 255.

FIG. 13 is a diagram showing the emission intensity of the color palette image taken by the camera 12 of the communication terminal 10, that is, the color palette image 13 reflected by the mirror unit 22 in step S15 for each color. It can be seen that the color regions C1 to C4 change to the color regions C1'to C4'as the reflected light in the mirror unit 22. It should be noted that the reference numeral C1 corresponds to C1', and similarly, the reference numerals C2 to C4 also have a corresponding relationship with each other.

Referring to FIG. 13, the reflected light in the mirror portion 22 of the red region C1 is the red region C1'. The red region C1 of the color palette image 13 facing the mirror unit 22 is composed of only the red component, but the red region C1'composed of the reflected light in the mirror unit 22 is not only the red component but also green and green. It can be seen that it contains a blue color component. This means that if the user U directly recognizes the red color, the red color is visually recognized as a bluish red color when the user U visually recognizes the red color through the mirror unit 22. It is considered that the mixing of green and blue color components is due to the influence of external light or the like or the reflection characteristics of the mirror of the mirror unit 22.

Similarly, the reflected light in the mirror portion 22 of the green region C2 is the green region C2'. The green region C2 of the color palette image 13 facing the mirror unit 22 is composed of only the green component, but the green region C2'composed of the reflected light in the mirror unit 22 is not only the green component but also red and red. It can be seen that it contains a blue color component. Similarly, with respect to the blue region C3, it can be seen that the blue region C3 is changed to the blue region C3'in which the red component and the green component are mixed due to the reflection in the mirror unit 22. Further, also in the white region C4, the balance of each color component is changed by the reflection in the mirror unit 22, and the white region C4'shows white with a relatively strong redness.

The color palette image obtained by the reflection in the mirror unit 22 shown in FIG. 13 is taken by the camera 12 of the communication terminal 10 in step S15, and transmitted to the light emission control device 20 by the communication unit 41 in step S16.

FIG. 14 is a diagram showing color comparison and LED light emission control accordingly. The color comparison is a process performed in step S26. Here, as an example, a color comparison is performed with respect to the white region C4 of the color regions C1 to C4. Of the reference color data of the color palette stored in advance in the light emission control device 20, the light emission intensity of the white region C4 is 255 for all the colors. On the other hand, the white region C4'of the received color palette image is configured as, for example, 180 for the red component, 150 for the green component, and 130 for the blue component.

In the color comparison, the difference in emission intensity between the white region C4 of the reference color data and the white region C4'of the received color palette image is calculated for each color. In this case, the difference between the reference color data and the received image data is 45 for the red component, 75 for the green component, and 95 for the blue component.

The light emission control process is performed in step S28 based on the result of the color comparison. Specifically, the calculation unit 614 calculates a correction value such that the difference value of the color component having the maximum difference among the color components is 255, and the light emitting unit 67 has a power based on this correction value. Supply is made. According to this example, among the differences of each color component, the difference of the blue component is the maximum at 95, and it is necessary to multiply this by 2.7 in order to make it 255. In other words, the light emission control unit 611 calculates 2.7 as a coefficient by dividing 255 by 95. When 2.7 is set as the coefficient, 2.7 is multiplied by the difference of each color. The red component has an emission intensity of about 121 obtained by multiplying 45 by 2.7, and the green component has an emission intensity of about 202 obtained by multiplying 75 by 2.7. The light emitting control unit 611 supplies power to the LEDs of each color so that the light emitting unit 67 has a light emitting intensity of 121 for the red component, 202 for the green component, and 255 for the blue component.

[Modification example]
The present invention is not limited to the above-described embodiment, and modifications, improvements, and the like to the extent that the object of the present invention can be achieved are included in the present invention.

For example, in the transmission process of the communication terminal 10 in the above-described embodiment, the end condition of step S17 may be modified. In the above-described embodiment, the end condition is the number of repetitions, but the end condition may be "when the result of the color comparison in step S26 falls within a predetermined range". That is, if the difference between the received color palette image and the reference color data does not significantly differ for each received color palette image, the color comparison may be completed.

As another modification, the code area 15 of the color palette image 13 used for color comparison may be configured not to be displayed. In this case, the received image analysis unit 612 performs image processing on the color regions C1 to C4 and detects a rectangular region of each color.

As another modification, for example, the CPU 61 of the light emission control device 20 may further include a calculation means and a display control means. The display control means calculates the color correction value based on the difference obtained in the above-mentioned color comparison. The display control means controls the display of the display 26 based on the color correction value. For example, the display control means may adjust the voltage applied to the liquid crystal molecules based on the difference of each color, and adjust the amount of light of the backlight transmitted through the color filter for each color. This makes it possible to adjust the emission intensity of the color component according to the difference, and it is possible to realize a display device having high color reproducibility.

As another modification, for example, the communication terminal 10 may include a color comparison unit for performing color comparison by the following method. The communication terminal 10 may calculate a value for controlling light emission of the display unit 21 of the light emission control device 20 by the following method in the color comparison unit. The same color palette image is recorded in advance on the communication terminal 10 and the light emission control device 20, and the color palette image is displayed on the display unit 21 of the light emission control device 20. The camera 12 of the communication terminal 10 captures a color palette image displayed on the display unit 21 of the light emission control device 20. The communication terminal 10 performs a color comparison between the color palette image saved in advance and the captured image. The communication terminal 10 transmits the difference in emission intensity of each color, which is the result of color comparison, to the emission control device 20. The light emission control device 20 performs light emission control processing of the display unit 21 based on the difference received from the communication terminal 10. The light emission control of the display unit 21 may be controlled by the power supply of the LED, or may be performed by controlling the backlight of the display 26. The power supply of the LED and the control of the backlight of the display 26 are as described above. With the configuration of this modification, in the light emission control device 20, the image displayed on the display 26 transmitted through the mirror unit 22 is displayed in a more appropriate color.

As another modification, the light emission control device 20 may perform color correction of the image displayed on the screen 11 of the communication terminal 10. For example, in FIG. 4, the image pickup unit 23 photographs the display unit 11 on which the color palette image is displayed. The captured color palette image is recorded in the storage unit 70. The image comparison unit 613 performs color comparison between the captured color palette image and the reference color data previously recorded in the storage unit 70. The same method as described above may be used for color comparison. The image comparison unit calculates the correction parameter based on the difference for each color obtained by the color comparison. The correction parameter is transmitted from the communication unit 71 to the communication terminal 10. The CPU 31 of the communication terminal 10 performs color correction by adjusting the emission intensity of each color according to the received correction parameter. According to this modification, the accuracy of color development of the image displayed on the communication terminal 10 is improved. Further, when performing color comparison, the accuracy of color development of the color palette image displayed on the communication terminal 10 is improved, so that the light emission control device 20 performs more accurate light emission control.

As another modification, the color comparison may be performed not only on the white region C4 but also on all of the color regions C1 to C3. For example, a color comparison is performed for each color, and a light emission control process is performed by averaging the differences obtained as a result. According to this modification, by performing color comparison for each color, it is possible to detect components such as external light or reflection characteristics for each color. As a result, components such as external light can be accurately detected for each color, so that higher color reproducibility is realized.

As another modification, the color comparison may be performed by decomposing not only the three primary colors of RGB but also any other color component. Typical examples are, but not limited to, the three primary colors consisting of C (cyan), M (magenta), and Y (yellow).

As another modification, it has a color calibration function for correcting the difference in color due to the image sensor or the like between the image pickup unit 23 of the light emission control device 20 and the camera 12 of the communication terminal 10. You may. As a result, it is possible to reduce an error due to the performance of the image sensor or the like when the display units of each other are photographed.

As another modification, the arrangement of the light emitting unit 24 and the imaging unit 23 is not limited to the arrangement shown in the figure. For example, the light emitting unit 24 may be arranged in one place, or may be arranged in two or more places. Similarly, the number of image pickup units 23 is not limited to one, and a plurality of image pickup units 23 may be provided.

As another modification, the image comparison unit 613 may be configured to hold a table corresponding to the color reference chart in advance. That is, in the above-described embodiment, the image comparison unit 613 transfers the color palette image data transmitted from the communication terminal 10 and the reference color palette image data previously recorded in the storage unit 70 or the like for each color. And the correction value is calculated based on the result of the comparison. On the other hand, in this modification, the color correction value based on the comparison result is calculated in advance and is stored as a table in the storage unit 70.
As a result, the time for calculating the correction value and the processing load are reduced, so that the performance of the light emission control device 20 is improved.

As another modification, the reference color palette image may be configured to be displayed on another medium that cannot be communicated. For example, the color palette image displayed on the display screen 11 of the communication terminal 10 does not necessarily have to be displayed on an electronic medium, and may be paper or the like. In this case, the image comparison unit 613 needs to acquire the color palette image reflected on the mirror unit 22 by a method other than communication. As an example, it is assumed that the image pickup unit 23 is attached to the upper part of the display unit 21 via a bendable bellows or the like. The image pickup unit 23 faces the mirror unit 22 due to the curvature of the bellows, and acquires a color palette image reflected on the mirror unit 22. As a result, the color palette image displayed on the paper medium is captured by the light emission control unit 20. The captured color palette image is obtained by the image comparison unit 613 in the same manner as in the above-described embodiment. The color correction value is calculated by comparing with the color standard chart.

Further, in the above-described embodiment, the light emission control device 20 to which the present invention is applied has been described as an example of an electronic device incorporated in a portable self-supporting mirror, but the present invention is not particularly limited thereto.
