An imaging device comprising: a body; an imaging portion configured to image a subject; a positional information acquisition portion configured to acquire positional information of an existence position of the body; a control portion configured to acquire information on the subject based on the positional information, and to display image data of the subject and the information on the subject on a display portion, the control portion having an augmented reality display mode; a memory portion and characterized in that the imaging device further comprising an AR information memory portion; and a hold control portion configured to output a hold control signal, which is used for holding the image data of the subject and the information on the subject in the AR display mode, to the control portion based on a user action while the control portion is in the AR display mode, wherein the control portion is configured to, when the hold control signal is received from the hold control portion, write and store the image data of the subject on the memory portion and the information on the subject on the AR information memory portion, which have been cached immediately before receiving the hold control signal or before a preset time from receiving the hold control signal, and wherein the hold control portion is configured to detect a motion with respect to the body or a signal output by the motion of the body as the user action and output the hold control signal to the control portion (a) when acceleration data of more than a predetermined threshold value is supplied from an acceleration sensor of the imaging device, or (b) when an elevation change, which is equal to or greater than the preset threshold value, is supplied from an elevation sensor of the imaging device, or (c) when an image pattern change, which is equal to or greater than a predetermined threshold value, is detected such that, in a state where the body is directed in a direction different from the acquisition direction of the information on the subject, the image data of the held subject and the information on the subject are displayed on the display portion. a body; an imaging portion configured to image a subject; a positional information acquisition portion configured to acquire positional information of an existence position of the body; a control portion configured to acquire information on the subject based on the positional information, and to display image data of the subject and the information on the subject on a display portion, the control portion having an augmented reality display mode; a memory portion and characterized in that the imaging device further comprising an AR information memory portion; and a hold control portion configured to output a hold control signal, which is used for holding the image data of the subject and the information on the subject in the AR display mode, to the control portion based on a user action while the control portion is in the AR display mode, wherein the control portion is configured to, when the hold control signal is received from the hold control portion, write and store the image data of the subject on the memory portion and the information on the subject on the AR information memory portion, which have been cached immediately before receiving the hold control signal or before a preset time from receiving the hold control signal, and wherein the hold control portion is configured to detect a motion with respect to the body or a signal output by the motion of the body as the user action and output the hold control signal to the control portion (a) when acceleration data of more than a predetermined threshold value is supplied from an acceleration sensor of the imaging device, or (b) when an elevation change, which is equal to or greater than the preset threshold value, is supplied from an elevation sensor of the imaging device, or (c) when an image pattern change, which is equal to or greater than a predetermined threshold value, is detected such that, in a state where the body is directed in a direction different from the acquisition direction of the information on the subject, the image data of the held subject and the information on the subject are displayed on the display portion.
