Problems solved by technology

[0006] However, even in the configuration of Patent Document 1, since the captured image displayed on the tablet terminal is indirectly drawn, there is a problem of lack of intuition compared to the case of directly drawing the subject.
Especially when the subject is a three-dimensional object, it may be difficult to draw to the desired position due to the difference in the shape of the subject and the imaging direction.

[0046] figure 1 It is a system configuration diagram of the projection system SY according to one embodiment of the present invention. The projection system SY is composed of a camera 1 and a projector 2 , which are connected via a cable 4 .

[0047] The document camera 1 includes a box-shaped housing 11 , a support arm 12 extending upward from an end of the housing 11 , and a camera 13 fixed to the upper end of the support arm 12 . On the upper surface of the casing 11 are provided a rectangular table 11 a viewed from above (the camera 13 side), and an operation panel 14 on which a plurality of operation keys are arranged. In addition, a planar or three-dimensional subject 50 is placed on the table 11 a (the figure shows a case where the planar subject 50 is placed).

[0048] In addition, the document camera 1 is provided with a luminescent pen 3 (operating body). The pen tip 32 at the tip of the luminescent pen 3 is provided with an LED (illuminator), and when the user br...

[0083] Next, refer to Figure 6 ~ Figure 8 , the second embodiment of the present invention will be described. In the above-mentioned first embodiment, when a drawing operation is performed, a composite image of the captured image 50m of the subject 50 and the drawing trajectory L is generated as the output image G. The output image G is output in case of operation. Hereinafter, only points different from the first embodiment will be described. However, in this embodiment, the same components as those in the first embodiment are assigned the same symbols, and detailed descriptions thereof are omitted. In addition, modifications applied to the same components as those of the first embodiment are also similarly applied to this embodiment.

[0084] Image 6 It is a block diagram of the document camera 1 of the second embodiment. The book camera 1 of the present embodiment is the same as the first embodiment (refer to figure 2 ) is different in that the output image selecti...

Abstract

The invention provides an overhead camera capable of realizing visually carrying out portraying operation on a shot object while carrying out simulation writing-in to a photographing image. The overhead camera includes an imaging section that captures an image of a subject, a position recognition section that recognizes a position specified with an operation member operated toward the subject, and a projection section that projects a predetermined image in the position specified with the operation member.

Description

technical field [0001] The invention relates to a painting and calligraphy camera and a control method for the painting and calligraphy camera. Background technique [0002] Conventionally, as such a technology, there is known an imaging solution composed of a drawing camera, a tablet terminal, and a display. For example, Non-Patent Document 1 discloses a configuration in which an image captured by a drawing camera and a drawn image based on a drawing operation performed by a tablet terminal are synthesized and displayed on a display. With this configuration, dummy writing can be performed on the captured image displayed on the display. [0003] However, in the case of Non-Patent Document 1, it is necessary to perform a drawing operation on the tablet terminal in hand while looking at the display, so there is a problem that it is difficult to draw at a desired position of a captured image displayed on the display. In view of this, in order to solve this problem, Patent Doc...
