A remote instruction system includes a control portion. The control portion transmits a first image to a remote terminal and controls a projection portion to project a first annotation image onto a subject according to an instruction issued from the remote terminal on the basis of the first image, and the control portion transmits a second image to the remote terminal and controls the projection portion to project a second annotation image onto the subject according to the instruction issued from the remote terminal on the basis of the second image, the first image being captured by a first image capturing portion provided for capturing the first image of the subject, the second image being captured by a second image capturing portion provided for zooming a given area of the subject to capture the second image, when the given area in the first image is selected from the remote terminal.

1. Technical Field
This invention generally relates to a remote instruction system and a remote instruction method.
2. Related Art
Embodiments of the present invention will be described in detail based on the following figures, wherein:
FIG. 1 is a configuration diagram illustrating an exemplary embodiment of a remote instruction system;
FIG. 2 is a flowchart showing an example process on a server with the use of the camcorder of a subject side apparatus;
A description will now be given, with reference to the accompanying drawings, of embodiments of the present invention. FIG. 1 is a configuration diagram illustrating an exemplary embodiment of a remote instruction system 1. The remote instruction system 1 includes a subject side apparatus 10 and a remote terminal 100. The subject side apparatus 10 and the remote terminal 100 are connected to each other to enable mutual communication by a network 300. In FIG. 1, only one remote terminal 100 is shown, however, multiple remote terminals 100 can be connected to a server 50, as will be discussed later, of the subject side apparatus 10 through the network 300.
The subject side apparatus 10 is composed of a camcorder 20 serving as a first image capturing portion, a PTZ camcorder 30 serving as a second image capturing portion, a projector 40 serving as a projection portion, the server 50 serving as a control portion, a half mirror 60, and a rotation stage 70 serving as a relative position changing portion. The camcorder 20 is composed of a CCD camera, for example, to capture a subject (target object) 200 placed on the rotation stage 70, while information of such captured image is being taken into the server 50. The PTZ camcorder 30 is a camera that can pan, tilt, and zoom the subject 200, and magnifies a selected given area in the subject 200 when the given area in the captured image is selected by the remote terminal 100 to capture the image thereof. The positional relationship between the camcorder 20 and the PTZ camcorder 30 are calibrated in advance. The camcorder 20 captures images transmitted through the half mirror 60.
The projector 40 is composed of a liquid crystal projector or the like, and projects an annotation image 201 on to the subject 200, according to an instruction given from the remote terminal 100 on the basis of a captured image. In addition, the projector 40 is arranged in such a manner that an optical system thereof is substantially aligned with an optical principal point of the camcorder 20 by the half mirror 60. The projector 40 projects the annotation image transmitted from the server 50 onto the subject 200 through an optical system thereof and the half mirror 60. The annotation image projected from the projector 40 is reflected by the half mirror 60 and projected onto the subject 200. The annotation image includes any type of image such as line, character, drawing, and the like.
