Abstract

A document camera includes: n (n≧2) imagers; a temporal storage that temporarily stores m sets of image data captured by m (1≦m≦n) imagers among the n imagers; an image processor that performs predetermined image processing according to the number of image data sets m on the m sets of image data stored in the temporal storage; and an output image data output unit that outputs output image data to a display apparatus, the output image data being a single output image data set produced in the predetermined image processing.

Claims

1. A document camera comprising:

n (n≧

2) imagers;

a temporal storage that temporarily stores m sets of image data captured by m (1≦

m≦

n) imagers among the n imagers;

an image processor that performs predetermined image processing according to the number of image data sets m on the m sets of image data stored in the temporal storage; and

an output image data output unit that outputs output image data to a display apparatus, the output image data being a single output image data set produced in the predetermined image processing.

2. The document camera according to claim 1,

further comprising an image processing mode selector for selecting an image processing mode when m≧

2,

wherein the predetermined image processing is a process selected by using the image processing mode selector.

3. The document camera according to claim 2,

wherein the image processing mode includes, as the predetermined image processing, a comparison mode in which (m−

1) sets of image data among the m sets of image data are processed into transparent image data sets and the m sets of image data are combined into a single output image data set so that the image data sets having undergone the transparency process are superimposed on the remaining image data set not having undergone the transparency process.

4. The document camera according to claim 2,

wherein the image processing mode includes, as the predetermined image processing, a simultaneous display mode in which the m sets of image data are combined into a single output image data set so that the m sets of image data are displayed side by side.

5. The document camera according to claim 2,

wherein the image processing mode includes, as the predetermined image processing, an individual switching mode in which m sets of output image data that allow the m sets of image data to be individually displayed are produced, and

the output image data output unit outputs any one of the m sets of output image data sets when the individual switching mode is selected.

6. The document camera according to claim 2,

wherein the image processing mode includes, as the predetermined image processing, a composite switching mode in which a first output image data set obtained by combining the m sets of image data so that the m sets of image data are displayed side by side and m sets of second output image data that allow the m sets of image data to be separately displayed are produced, and

the output image data output unit outputs any one of the first output image data set and the m sets of second output image data when the composite switching mode is selected.

7. A method for controlling a document camera including n (n≧

2) imagers and a temporal storage, the method comprising;

an image capture of capturing m sets of image data by using m (1≦

m≦

n) imagers among the n imagers;

a storage of temporarily storing the m sets of captured image data in the temporal storage;

an image processing of performing predetermined image processing according to the number of image data sets m on the m sets of image data stored in the temporal storage; and

an output image data output of outputting output image data to a display apparatus, the output image data being a single output image data set produced in the predetermined image processing.

8. The method for controlling a document camera according to claim 7,

wherein the document camera further includes an image processing mode selector for selecting an image processing mode,

the method further comprising a selection result acquisition of acquiring a result of selection made by using the image processing mode selector when m≧

2, and

in the image processing, the predetermined image processing selected by using the image processing mode selector is performed.

9. A program that instructs a computer to carry out in the method for controlling a document camera according to claim 7.

10. A program that instructs a computer to carry out in the method for controlling a document camera according to claim 8.
