IMAGE CAPTURING DEVICE, IMAGE CAPTURING CONTROLLER USED FOR THIS DEVICE, IMAGE CAPTURING CONTROL METHOD, AND IMAGE CAPTURING CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To improve operability of an image capturing device that captures and projects the image of a subject, such as a document placed on a placing table, for example, a book/painting stand.;SOLUTION: When a presenter places a document on the placing table (phase P), a comparison of the total of the pixel values of each frame of an image signal v is made frame by frame by a personal computer 60, so that a change indicating that the image signal v exceeding the predetermined reference value is detected, and thus the placement of the document on the placing table is sensed. Then, when a display program is not in an active mode, the display program is switched to the active mode (phase N). In addition, an image projected on a screen by the projector is automatically switched and the image of a subject on the placing table is displayed. This makes it unnecessary for the presenter to go back and forth between an image reader (stand type scanner) and the personal computer 60 and such cases that explanations during the presentation or the like are interrupted and waste of time occurs are not caused.;COPYRIGHT: (C)2008,JPO&INPIT
