Abstract

An imaging device includes an imaging portion that images a subject; a positional information acquisition portion that acquires positional information of an imaging position; a control portion which acquires information on the subject based on the positional information, and displays image data of the subject and the information on the subject on a display portion; and a hold control portion that outputs a hold control signal, which holds the image data of the subject and the information on the subject, to the control portion.

First claim

What is claimed is:

1. An imaging device comprising:
a body;
an imager;
a display; and
a computer configured to
display, on the display, (i) a real-time image acquired via the imager capturing a subject and (ii) subject information acquired based on a result of an image recognition for the real-time image,
hold, on the display, the real-time image and the subject information displayed on the display based on an action detection of at least one of (i) a movement of a detected characteristic point of the real-time image in a preset distance in a time of a preset range, (ii) a change of a detected contrast of the real-time image, (iii) a change in an image pattern of the real-time image, which is equal to or greater than a predetermined threshold value, (iv) a user action in which a button is pressed down, and (v) a user action in which a touch panel is touched, and
continue displaying the held real-time image and the held subject information on the display after the action detection.

2. The imaging device according to claim 1 , wherein the computer is configured to transmit the held real-time image and the held subject information to another terminal.

3. The imaging device according to claim 1 , wherein the display has a touch panel that is configured to be operative for a touch operation while the held real-time image and the held subject information are displayed on the display.

4. The imaging device according to claim 1 , wherein the computer is configured to switch between a display mode and a non-display mode of the subject information on the display.

5. The imaging device according to claim 1 , wherein the computer is configured to display a past image relating the subject on the display.

6. The imaging device according to claim 1 , wherein the subject information is augmented reality information.

7. The imaging device according to claim 1 , wherein the subject information is an icon of navigation.

8. An information acquisition system comprising:
the imaging device of claim 1 ; and
an information retrieval system.

9. The information acquisition system according to claim 8 , wherein the information retrieval system has a memory to store the held real-time image and the held subject information.

10. A non-transitory computer-readable storage medium that stores a program that allows a computer to execute functions of an imaging device so that the computer executes the steps comprising:
acquiring subject information based on a result of an image recognition for a real-time image, which is acquired via an imager of the imaging device capturing a subject;
displaying the real-time image and the subject information on a display;
holding, on the display, the real-time image and the subject information displayed on the display based on an action detection of at least one of (i) a movement of a detected characteristic point of the real-time image in a preset distance in a time of a preset range, (ii) a change of a detected contrast of the real-time image, (iii) a change in an image pattern of the real-time image, which is equal to or greater than a predetermined threshold value, (iv) a user action in which a button is pressed down, and (v) a user action in which a touch panel is touched; and
continuing displaying the held real-time image and the held subject information on the display after the action detection.

11. In combination, a server and the imaging device of claim 10 , wherein the server is configured to communicate with the imaging device to acquire subject information from a database and to transmit the subject information to the imaging device.

12. An imaging device comprising:
a body;
an imager;
a display;
a computer configured to
display, on the display, (i) a subject image acquired via the imager and (ii) subject information acquired based on a result of an image recognition for the subject image,
hold, on the display, the subject image and the subject information displayed on the display when a change in an image pattern, which is equal to or greater than a predetermined threshold value, is detected, and
continue displaying the held subject image and the held subject information on the display after the detection.

13. The imaging device according to claim 12 , wherein the subject information is augmented reality information.

14. An information acquisition system comprising:
the imaging device of claim 12 ; and
an information retrieval system.

15. In combination, a server and the imaging device of claim 12 , wherein the server is configured to communicate with the imaging device to acquire subject information from a database and to transmit the subject information to the imaging device.

16. A non-transitory computer-readable storage medium that stores a program that allows a computer to execute functions of an imaging device so that the computer executes the steps comprising:
acquiring subject information based on a result of an image recognition for a subject image, which is imaged via an imager of the imaging device;
displaying the subject image and the subject information on a display;
holding, on the display, the subject image and the subject information displayed on the display when a change in an image pattern, which is equal to or greater than a predetermined threshold value, is detected, and
continuing displaying the held subject image and the held subject information on the display after the detection.

17. An information acquisition system comprising:
an imaging device which includes an imager, a body, a display and a computer; and
a database;
wherein the computer is configured to
display a subject image acquired via the imager and subject information acquired based on a result of an image recognition for the subject image;
store the subject image and the subject information in the database, while the subject image and the subject information is displayed on the display, based on an action detection of at least one of (i) a change of a detected contrast of the subject image, (ii) a change in an image pattern of the subject image, (iii) a user action in which a button is pressed down, and (iv) a user action in which the display is touched.

18. The information acquisition system according to claim 17 , wherein the subject information is augmented reality information.

19. The information acquisition system according to claim 17 , wherein the computer is configured to also store a parameter or an imaging date and time, which is related to the subject information, in the database in addition to the subject image and the subject information while the subject image and the subject information is displayed on the display.

20. An imaging device comprising:
a body;
an imager;
a display; and
a computer configured to
display, on the display, (i) a real-time image acquired via the imager capturing a subject and (ii) subject information acquired based on a result of an image recognition for the real-time image,
hold, on the display, the real-time image and the subject information displayed on the display based on an action detection of at least one of (i) a movement of a detected characteristic point of the real-time image in a preset distance in a time of a preset range, (ii) a change of a detected contrast of the real-time image, (iii) a change in an image pattern of the real-time image, which is equal to or greater than a predetermined threshold value, and (iv) a user action in which a button is pressed down, and
switch between a first mode and a second mode ba
