Abstract

A document camera includes a stand and a digital camera attached thereto to be freely detachable, and ensures an electrical connection therebetween at an attaching time. The digital camera is structured to be usable as a single unit. Moreover, a charging circuit is provided in the stand to make it possible to charge the attached digital camera by an external power source. An image obtained by the digital camera or data of the recorded image is transferred to a PC via the stand, and the obtained (recorded) image is projected on a screen by a projector. Moreover, a mode change key, a shutter key, and the like are provided in the stand, making it possible to perform an operation for changing an operation mode, a still image shooting operation and the like in the digital camera and allow an operation from the PC via the stand.

Claims

1. A document camera that images an image to be projected by a projecting apparatus by an imaging section, comprising:

a digital camera having an image recording section that records the image imaged by the imaging section; and

a camera stand where the digital camera is attached to be freely detachable and an electrical connection with the attached digital camera is ensured and an operating section that electrically operates the digital camera is included.

2. The document camera according to claim 1, wherein the operation of the digital camera using the operating section is an operation mode change operation.

3. The document camera according to claim 1, wherein the operation of the digital camera using the operating section is an operation for changing the display contents of the image to be projected by the projecting apparatus.

4. The document camera according to claim 1, wherein the operation of the digital camera using the operating section is a still image shooting operation.

5. The document camera according to claim 1, wherein contents of the operation of the digital camera using the operating section can be arbitrarily set by a user, and the document camera has an operation recording section that records contents set by the user.

6. The document camera according to claim 1, wherein ensuring of the electrical connection by the camera stand with the digital camera is via a radio signal.

7. The document camera according to claim 1, wherein the camera stand has a lighting section that emits light to an imaging object to obtain a good shooting condition.

8. The document camera according to claim 7, wherein the lighting section uses an emission light of an LED.

9. The document camera according to claim 1, wherein the camera stand has a charging section that charges the digital camera.

10. A document camera that images an image to be projected by a projecting apparatus by an imaging section, comprising:

a digital camera having an image recording section that records the image imaged by the imaging section; and

a camera stand where the digital camera is attached to be freely detachable and an electrical connection with the attached digital camera is ensured and a connecting section that performs an electrical connection with an external device is included.

11. The document camera according to claim 10, wherein ensuring of the electrical connection by the camera stand with the digital camera is via a radio signal.

12. The document camera according to claim 10, wherein the camera stand has a lighting section that emits light to an imaging object to obtain a good shooting condition.

13. The document camera according to claim 12, wherein the lighting section uses an emission light of an LED.

14. The document camera according to claim 10, wherein the camera stand has a charging section that charges the digital camera.

15. A document camera system having a document camera that images an image to be projected by a projecting apparatus by an imaging section, comprising:

a digital camera having the imaging section and an image recording section that records the image imaged by the imaging section;

a camera stand where the digital camera is attached to be freely detachable and an electrical connection with the attached digital camera is ensured; and

an external operating device being electrically connected to the camera stand and having an operating section that electrically operates the digital camera via the camera stand.

16. The document camera system according to claim 15, wherein the external operating device comprises:

an image inputting section that inputs the image imaged by the digital camera via the camera stand; and

an image outputting section that outputs a display image, which is based on the image input to the image inputting section, to the projecting apparatus.
