- the imaging unit 111 images the light source 131 by the global shutter operation, and the imaging frame rate of the imaging unit 111 is higher than the frequency at which the visible light communication control unit 132 controls the light emission state of the light source 131. This is a method for acquiring identification information in a fast case.
- FIG. 6 is an explanatory diagram illustrating a global shutter operation in the imaging apparatus.
- the global shutter operation is one of shutter operations in the image pickup apparatus, and is a shutter operation in which all pixels of the image pickup apparatus perform image pickup at the same time. As shown in FIG. 6, in an imaging apparatus that performs a global shutter operation, when imaging one frame, for example, pixels in all lines start exposure at the same time and end exposure at the same time.
- the image captured by such a global shutter operation is captured as an image having a uniform light emission state in the entire image because the pixels in all the lines reflect the light emission state of the light source 131 in the same period.
- the imaging unit 111 that performs the global shutter operation acquires the change in the light emission state of the light source 131 by setting the imaging frame rate faster than the control frequency of the light emission state of the light source 131 by the visible light communication control unit 132. Can do.
- the imaging unit 111 that performs a global shutter operation can detect a change in the light emission state of the light source 131 by setting the sampling frequency for imaging higher than the control frequency of the light emission state of the light source 131. Therefore, the identification information acquisition unit 112 can acquire the identification information of the information processing device 13 from the change in the light emission state of the light source 131.

- a shutter operation in which the pixels of the imaging device sequentially perform imaging for each pixel group (for example, line).
- FIG. 7 in an imaging apparatus that performs a rolling shutter operation, when one frame is imaged, exposure is started sequentially from top to bottom for each pixel of each line. More specifically, the exposure of the pixels of each line is started in order at intervals of time t, and the exposure is sequentially terminated after a certain exposure time has elapsed.
- the image captured by such a rolling shutter operation reflects the light emission state of the light source 131 during the period in which the pixels of each line are different. Therefore, when the light emission state of the light source 131 changes in time series, an image in which the light emission state changes for each line in the entire image is obtained. That is, when the luminance of the light source 131 changes in time series, the image taken by the rolling shutter operation is taken as an image in which horizontal stripes having dark lines and bright lines are formed according to the time series change in luminance.
- the imaging unit 111 that performs the rolling shutter operation changes the light emission state of the light source 131 even if the imaging frame rate is slower than the control frequency of the light emission state of the light source 131 by the visible light communication control unit 132. It can be acquired as a horizontal stripe pattern.
- the imaging unit 111 that performs a rolling shutter operation can detect a change in the light emission state of the light source 131 even if the sampling frequency by imaging is lower than the control frequency of the light emission state of the light source 131. Therefore, the identification information acquisition unit 112 can acquire the identification information of the information processing device 13 from the change in the light emission state of the light source 131.
- the change in the light emission state of the light source 131 is obtained by making the imaging frame rate faster than the control frequency of the light emission state of the light source 131 by the visible light communication control unit 132. It goes without saying that you can do it.

Here, the identification information acquisition unit 112 may detect the background region 211A by storing the hue of the background region 211A in advance. Further, the identification information acquisition unit 112 may regard the widest region of the same hue region in the display image 211 as the background region 211A.

- the identification information acquisition unit 112 calculates the average value of the pixel values of all lines from the integrated value of the pixel values for each line, and the ratio of the integrated value of the pixel values of each line to the average value of the pixel values of all lines Is calculated. Further, the identification information acquisition unit 112 processes the ratio of the integrated values of the pixel values of each line by a shutter function based on the rolling shutter operation. Thereby, the identification information acquisition unit 112 can separate the encoded identification information from the display image 211. Furthermore, the identification information acquisition unit 112 can acquire the identification information of the information processing device 13 by decoding the encoded identification information.
- the integrated value i (y) obtained by integrating the pixels of the background area 211A for each line is s (t) for the shutter function, f (t) for the identification information, and i bg for the hue information for the background area 211A. Then, it can be expressed by the following formula 101.

- FIG. 10 is an explanatory diagram for explaining an operation when images are taken simultaneously at different exposure times in an imaging apparatus that performs a rolling shutter operation.
- the imaging apparatus when imaging one frame, the imaging apparatus performs a rolling shutter operation in which exposure is sequentially started for each line. However, each line is exposed with a different exposure time every other line. According to this configuration, although the resolution in the vertical direction is reduced, the imaging apparatus can simultaneously acquire images taken at different exposure times.
- the identification information acquisition unit 112 uses a plurality of images captured at different exposure times, so that even when the background area 210A cannot be detected from the display image 210 or when the display image 210 is a moving image, Identification information can be acquired.
- the method for controlling the exposure time of each pixel is not particularly limited as long as the imaging device can simultaneously image the light source 131 with different exposure times. That is, the imaging apparatus may control the exposure time for each line or the exposure time for each pixel in order to capture images with different exposure times.
- FIG. 11 is an explanatory diagram illustrating an example of an image displayed on the display device (that is, the light source 131) of the information processing device 13, and FIG. 12 illustrates the identification information acquisition unit 112 from the image illustrated in FIG. It is explanatory drawing which showed the method to acquire.

- the identification information acquisition unit 112 can acquire identification information by using a plurality of display images 221A and 221B having different exposure times. Specifically, the identification information acquisition unit 112 extracts the display images 221A and 221B of the light source 131 from the image captured by the imaging unit 111.
- the display images 221A and 221B are images captured at different exposure times, the integration times of changes in the light emission state (for example, luminance) of the light source 131 are different, and images having different bright and dark horizontal stripes are formed. It has become.
- the integrated value i 1 (y) obtained by integrating the pixels of the display image 221A for each line and the integrated value i 2 (y) obtained by integrating the pixels of the display image 221B for each line are the same as in the second acquisition method.
- the shutter functions as s 1 (t) and s 2 (t)
- the identification information as f (t)
- the hue information i bg (y) of the original images of the display images 221A and 221B 201 and Formula 202.
- y represents the position of the display images 221A and 221B in the vertical direction
- t is time.
- i 1 (y) and i 2 (y) can be calculated from the display images 221A and 221B. Further, s 1 (t) and s 1 (t) are known shutter functions. Therefore, by erasing i bg (y) in Equation 201 and Equation 202, the identification information acquisition unit 112 can calculate the identification information f (t).

- the change in the light emission state of the light source 131 is integrated over the entire captured image. It becomes uniform. That is, since the captured display image is an image in which bright and dark horizontal stripes are not formed, i 1 (y) can be expressed by a simpler expression like Expression 203 below. Therefore, in such a case, the formula 202 can be transformed as the following formula 204.

Therefore, the identification information acquisition unit 112 can more easily separate the encoded identification information from the display images 221A and 221B, as in the second acquisition method.
