1. A display method for a display apparatus to display an image, the display method comprising:
- (a) obtaining a captured display image by using an image sensor with a first exposure time;
(b) obtaining light identification information by visible light communication with a subject, wherein the subject transmits the light identification information by change in luminance by causing at least one light emitting element to blink;
(c) transmitting the light identification information to a server;
(d) obtaining, from the server, an augmented reality image and recognition information which are associated with the light identification information, wherein the recognition information indicates a location of a target region within the captured display image;
(e) recognizing the target region within the captured display image using the recognition information; and
(f) displaying the captured display image in which the augmented reality image is superimposed on the target region,whereinthe obtaining of the light identification information includes;
obtaining a decode target image by using the image sensor with a second exposure time which is shorter than the first exposure time; and
obtaining the light identification information by decoding the decode target image.

Abstract
A display method is for a display apparatus to display an image, and includes: obtaining a captured display image and a decode target image by an image sensor capturing an image of a subject; obtaining a light ID by decoding the decode target image; transmitting the light ID to a server; obtaining, from the server, an AR image and recognition information which are associated with the light ID; recognizing a region according to the recognition information as a target region from the captured display image; and displaying the captured display image in which the AR image is superimposed on the target region.

13. The display method according to claim 1, wherein
(f) further includes: -
determining whether a face of a user is approaching the display apparatus, based on image capturing by a face camera included in the display apparatus; and displaying a first augmented reality image which is the augmented reality image while preventing display of a second augmented reality image different from the first augmented reality image, when the face is determined to be approaching.

14. The display method according to claim 1, wherein
(f) further includes: -
determining whether a face of a user is approaching the display apparatus, based on an acceleration of the display apparatus measured by an acceleration sensor; and displaying a first augmented reality image which is the augmented reality image while preventing display of a second augmented reality image different from the first augmented reality image, when the face is determined to be approaching.

15. The display method according to claim 1, wherein
the captured display image and the decode target image are obtained by the image sensor capturing an image which includes a plurality of displays each showing an image, in (e), a region in which, among the plurality of displays, a transmission display that is transmitting the light identification information is shown is recognized as the target region from the captured display image, and in (f), first subtitles for an image displayed on the transmission display are superimposed on the target region, as the augmented reality image, and second subtitles obtained by enlarging the first subtitles are further superimposed on a region larger than the target region of the captured display image. -
16. The display method according to claim 15, wherein
(f) further includes: -
determining whether information obtained from the server includes sound information; and preferentially outputting sound indicated by the sound information over the first subtitles and the second subtitles, when the sound information is determined to be included.

17. A display apparatus which displays an image, the display apparatus comprising:
-
a processor; and a memory in which a computer program is stored, wherein the computer program causes the processor to perform the display method according to claim 1 when the computer program is executed by the processor.
-
-
18. A non-transitory recording medium in which a computer program is stored, the computer program causing a processor to perform the display method according to claim 1 when the computer program is executed by the processor.
-
19. The display method according to claim 1, wherein
the displaying superimposes the augmented reality image only on the captured display image among the captured display image and the decode target image. -
20. The display method according to claim 1, wherein
the obtaining of the light identification information includes: -
setting the second exposure time of the image sensor which has a plurality of exposure lines, so that, in an image obtained by capturing the subject by the image sensor, a bright line corresponding to each of the plurality of exposure lines included in the image sensor appears according to the change in luminance of the subject; obtaining the decode target image including a plurality of bright lines, by capturing the subject that changes in luminance by the image sensor with the set second exposure time; obtaining the light identification information by demodulating data specified by a pattern of the plurality of bright lines included in the obtained decode target image.

21. A display method, comprising:
-
(a) obtaining a captured image by an image sensor, at a first exposure time, capturing an image of, as a subject, a still image illuminated by a transmitter which transmits a signal by changing luminance by causing at least one light emitting element to blink; (b) obtaining the signal by visible light communication with the still image which is illuminated by the transmitter which transmits the signal by changing luminance by causing the at least one light emitting element to blink; and (c) reading a video corresponding to the obtained signal from a memory, superimposing the video on a target region corresponding to the still image in the captured image, and displaying, on a display, the captured image in which the video is superimposed on the target region, the video including a plurality of images, a leading image of the plurality of images being the same as the still image, wherein in (c), the video is displayed, starting with the leading image same as the still image, by superimposing the leading image on the target region corresponding to the still image at the start of displaying the video, the obtaining of the signal includes; obtaining a decode target image by using the image sensor with a second exposure time which is shorter than the first exposure time; and obtaining the signal by decoding the decode target image. - View Dependent Claims (22, 23)
