DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a picture drawing recording apparatus for recording a picture being drawn and a picture drawing display system for displaying a picture being drawn.

[0002]

2. Description of the Related Art As a teaching material for calligraphy and sumi-e, there is a case where a video image of a teacher who is actually drawing is used. In order to record the depiction of characters and ink painting using a brush, the depiction is usually taken with a video camera. It is preferable that the photographing is performed from the front of Japanese paper such as semi-paper on which characters and ink painting are drawn. However, since the brush and the hand holding the brush are positioned above the half-paper, a part of the drawn characters and ink painting is hidden by the brush and the hand.

For this reason, in many cases, photographing is performed from an oblique direction of a half-sheet so that characters and ink are not hidden by a brush or a hand. However, when photographing from an oblique direction, characters and ink paintings are also photographed obliquely, so the impression is different from that when photographing from the front side of a semi-paper. Especially the impression of the shade of ink differs. Moreover, since the brush and hand are located above the half-paper, it is still difficult to see the characters and the ink painting being drawn.

[0004] A learner practices drawing of characters and ink painting with reference to the above-mentioned video image. Such a learning method using a video image as a teaching material is often a one-way instruction from a teacher to a learner. In distance learning, when a student mails an assignment, the teacher may correct the assignment and return it to the learner. However, it is difficult for the correction via mail to provide guidance on operations such as writing pressure and speed of moving the writing brush.

[0005] Other examples of writing characters with a brush include, for example, waka and haiku. In many cases, presentations of waka or haiku are simply reading aloud waka or haiku, or simply displaying a display board on which waka or haiku is written. However, just reading aloud and exhibiting the presentation effect is low.

The inventor of the present invention has conducted intensive studies to solve such problems, and as a result, has arrived at the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a schematic drawing recording apparatus according to an embodiment of the present invention.

FIG. 1 shows a picture drawing recording apparatus 10 according to the present invention.
The outline of is shown. The depiction drawing recording device 10 is shown in FIG.
As shown in (b), a transparent plate 12 through which a graphic image drawn on the front side 12a is transmitted to the back side 12b,
Recording means (22, 16) for recording the figure image transmitted to 2b
And Here, the graphic image has graphic characteristics such as shape, pattern, and color. The recording means is the transmission plate 12
Reversing means for reversing the figure image transmitted to the back side 12b
(22) and a photographing means (16) for photographing the inverted picture.

The transmissive plate 12 only needs to have transparency so that the drawing drawn on the front side 12a can be seen from the back side 12b, but is preferably colorless and transparent so that it can be clearly seen. Further, since the drawing is drawn on the transmission plate 12, it is preferable that the plate is a flat plate having sufficient strength to draw the drawing without any problem. In this description, a colorless and transparent glass flat plate is used.

The reversing means (22) is provided on the back side 1 of the transmission plate 12.
2b includes a mirror surface 14 from which a figure image transmitted to the mirror 2b is reflected. In this description, a mirror is used. As shown in FIG. 2A, the mirror surface 14 is positioned at a distance of 4 from the surface of the transmission plate 12 on which a picture is drawn.
It is tilted 5 degrees. On the mirror surface 14, the rear side 1 of the transmission plate 12 is provided.
A picture in the same state as when viewed from the front side 12a is obtained by inverting the picture viewed from 2b.

The photographing means (16) is a device for photographing the state of drawing of a picture displayed on the mirror surface 14, and for example, a video camera can be used. The shooting direction (X direction in the figure) of the video camera 16 is set to a direction that is 45 degrees oblique to the mirror surface 14 and parallel to the surface of the transmission plate 12. Transmission plate 1
By setting the angle 2 and the mirror surface 14 and the mirror surface 14 and the photographing direction to 45 degrees, distortion of a photographed image can be minimized.

Next, a description will be given of the operation of the imaging of the depiction state by the depiction / drawing recording apparatus 10.

Although it is possible to write characters directly on the transmission plate 12, in this description, the half paper 20 is placed on the transmission plate 12 and the half paper 2
Write a character at 0. The characters written on the front side of the half paper 20 can also be confirmed from the back side. There is no problem if a transparent paper on which the drawings written on the front side can be confirmed from the back side is placed on the transmission plate 12 and the drawings are drawn on the paper. Characters such as half-paper (ink)
When using paper that allows only light to pass through, the brush or hand for writing characters cannot be seen from the back side of the transmission plate 12.

When the characters are drawn on the half paper 20, the appearance of the characters viewed from the back side 12b of the transmission plate 12 is reflected on the mirror surface 14. In the present description, the characters viewed from the back side of the half paper 20 are projected on the mirror surface 14. The characters projected on the mirror surface 14 are the characters viewed from the back side of the half paper 20 reversed left and right or up and down, and are the same as the characters viewed from the front side of the half paper 20. The appearance of the characters projected on the mirror surface 14 shown in FIG. 3 is captured by the video camera 16.

Since the photographing is performed from the back side of the half paper 20, the characters are not hidden by the brush and the hand. Since the half paper 20 transmits almost only characters to the back side, the brush and the hand are not photographed. It is not difficult to see characters by hiding in a brush or hand as in the past. When viewed from the back side of the half paper 20, the pen pressure and the density of the ink become easier to understand than when viewed from the front side. Furthermore, since the photographing is not performed from the oblique direction of the semi-paper 20 as in the related art, but is performed substantially from the front side of the semi-paper 20, it is possible to accurately check the density of the ink, the shape of the characters, and the like.

The manner in which the characters photographed by the video camera 16 are described is recorded on a video tape after being edited by, for example, a video editing device or the like, and passed to the learner. The learner plays the character being drawn on the video playback device, and learns how to write the character while watching the teacher draw the character.

In the case where corrections are made by a teacher such as distance learning, the learner mails the assignment to the teacher side, for example, as in the conventional case. The teacher who receives the learner's assignment corrects the assignment in, for example, vermilion. The depiction of vermilion characters at the time of correction can be taken by the depiction drawing recording device 10. As in the above description, a state in which vermilion characters are drawn is photographed by a video camera.

The video tape on which the corrected task and the state of the correction are recorded is returned to the learner. Learners
You can learn more about correct writing by looking at the video of the corrected task and the state of the correction. By using an image of the state of the correction according to the present invention as well as the previously corrected problem, the learner can receive the correction including the operation such as the pen pressure and the speed of moving the brush. .

Although the embodiment of the present invention has been described above, the picture drawing recording apparatus according to the present invention can be implemented in other modes. For example, the transmission plate 12 and the mirror surface 14
And the angle between the mirror surface 14 and the photographing direction are not limited to 45 degrees, but may be any angles. However,
The angle is set so that the shape of the picture to be photographed is not deformed. Considering the installation place of the transmission plate 12 and the imaging device 16, 30
It is preferable to set the angle from 60 degrees to 60 degrees. By setting the angle between the transmission plate 12 and the imaging device 16 first, and then adjusting the angle of the mirror surface 14, the above-described angle adjustment can be performed. The angle of the transmission plate 12 can be adjusted to any angle that is easy to describe.

The reversing means is not limited to a mirror surface. For example, as shown in FIG. 4A, a digital video camera 26 may be used as a recording means, and reversal processing may be applied to photographed digital image data. Inversion of image data is
The reversing function provided in the video camera 26 may be used, or image data captured by the digital video camera 26 may be input to a computer, and the reversing process may be performed by image processing software. As shown in FIG. 4B, a grid-like grid (dotted line in the figure) can be added by image processing software.

When writing characters on the half paper 20 with black ink, the black ink may bleed to the back surface of the half paper 20 and stain the transmission plate 12 in some cases.
As shown in FIG. 4C, by using the half paper 20 having one surface laminated (50) with vinyl or the like, the transmission plate 1
2 can be prevented from being stained with ink. Of course, an underlay having transparency and water resistance, such as vinyl, can be laid under the semi-paper 20.

The learner can also use a drawing and picture recording device. The learner, like the teacher, records the character drawing of the task on the video camera, and sends a video tape on which the character writing is recorded to the teacher together with the task. The teacher
Correct the assignment and play the videotape to check the learner's writing style. In addition to the conventional correction, it is possible to give advice on how to write (operation) of the learner.

The transmission of the photographed video from the teacher to the learner is not limited to a video tape, and any recording medium can be used. For example, LD (Laser Disk), DVD (Dig
Ital Video Disk) can also be used. After the captured video is converted into a moving image file playable on a personal computer or the like, it can be recorded on a data recording medium such as a CD-ROM and mailed. A moving image file and dedicated moving image reproducing software can be recorded on a data recording medium and mailed.
Any video recording / reproducing method and video recording medium can be used depending on the video reproducing means owned by the learner.

In addition to the mailing, for example, as shown in FIGS. 5A and 5B, photographed moving image data can be transmitted to the learner via a communication line such as the Internet. In FIG. 5A, the depiction and drawing recording device 10 includes a video recording unit 36.
In addition, a voice recording unit 38 is also included. Picture drawing recording device 10
If there is no voice input function, a voice input device such as a microphone is used separately. The input video and audio are transmitted from the communication device 44 after being edited by the video / audio editing device 42. The learner receives the data transmitted from the teacher side by the communication device 46 and reproduces the data by the video / audio reproduction device 48. The reproduced data is output to the display device 30. As the moving image data, not only the moving image data that has been shot, but also the moving image data that is being shot can be transmitted.

The mailing of the assignment from the learner to the teacher is not limited to paper. For example, an assignment can be read by an image input device such as an image scanner, and the read image data can be stored in an arbitrary data recording medium and mailed to the teacher. Alternatively, the read image data can be transmitted to the teacher using a communication line. As shown in FIG. 5B, two-way communication between the teacher and the learner can be performed using a communication line.

As mentioned above, various embodiments of the picture drawing recording apparatus according to the present invention have been described based on the drawings, but the present invention is not limited to the picture drawing recording apparatus shown in the drawings. For example, a drawing / drawing display system including the drawing / drawing recording device and the display device of the present invention can be used for presenting a waka or a haiku. The display device displays a state in which a drawing being recorded or a recorded drawing is drawn by the drawing drawing recording device. As shown in FIG. 6A, the display device 30 includes a sound output device 34 that outputs a sound for reading out the drawn characters.

The depiction / drawing display system reads a waka or a haiku, and displays the read characters. For example,
The video / audio reproduction device 48 reproduces the voice for reading the text and the state of the depiction of the recorded text in advance. Since the display of the character is a reproduction of the operation of writing a character, a presentation in which the voice and the character display are integrated can be performed. As shown in FIG. 6B, the drawing and picture recording device 10 and the display device 30 may be connected by a connection cable or may be connected by a communication line.

Drawings recorded by the picture drawing recording apparatus include figures, pictures and characters. It is not limited to characters, and it is possible to record and further display a state where a picture such as an ink painting is drawn. Drawings are not limited to drawings drawn with a brush, but include drawings drawn with any writing implement. Further, the color of the picture or the character to be drawn is not limited to black, and any color can be used. Multiple colors can be used.

The present invention can be embodied in variously modified, modified, and modified forms based on the knowledge of those skilled in the art without departing from the spirit of the present invention. Further, within the range in which the same operation or effect is produced, any of the invention specific items can be replaced with another technology.

[0038]

According to the picture drawing recording apparatus of the present invention, the picture drawing can be recorded in a moving picture format. Since the photograph is taken from the back side of the surface on which the characters are drawn, the drawing is not hidden by the brush or the hand holding the brush. In addition to confirming the outline of a character or the like as viewed from the front side, the pen pressure, the degree of adhesion of the brush, the state of the brush hair, and the like appearing on the back surface can be similarly confirmed.

According to the pictorial drawing display system of the present invention,
As the character is read out, it is possible to display how the character is drawn. The display of characters does not mean that the entire characters are displayed at once, but rather that the characters are written one by one in the same manner as when a person writes characters. Since the process of drawing the characters is displayed, the effect of the effect is higher than when displaying the entire characters at once.
