Problems solved by technology

[0004] However, it takes time for the user to draw the diagram by hand, and it doesn't look pretty
In addition, a method in which the user creates a graph image in advance on a PC, etc., and displays the graph image using a projector, etc. is also conceivable, but it takes time to prepare in advance, and in order to correct the graph during a presentation, it is necessary to leave the display area of ​​the image on a whiteboard, etc. to operate a PC, etc., the effect of the demonstration will be reduced
Moreover, this method cannot cope with the situation where a chart is drawn by handwriting on a whiteboard or the like using an ink pen, etc., and lacks flexibility

[0028] figure 1 It is a figure which shows the projection situation of 1st Example. The projector 100 is of a short-throw type, and projects an image 20 onto the whiteboard 10 in a state where it is mounted on a wall with an attachment 30 . A student 40 draws characters, lines, and the like on the whiteboard 10 with an ink pen 50 filled with paint or the like.

[0029] figure 2 is a diagram showing the input object 400 of the first embodiment. For example, the student 40 draws an L-shaped frame line as the input object 400 in a state where the image 300 is projected, and draws a numerical value under the frame line. Projector 100 recognizes the frame-line area as graph area 410 and the numerical value area as data area 420 , and generates and projects a graph image based on the contents of these areas.

[0030] image 3 is a diagram showing a graph image 500 in the first embodiment. For example, if figure 2 As shown, in the case where "10 30 40" is drawn as the numeri...

[0045] Next, an example will be described in which a user draws a type of graph with an electronic pen, and a projector projects a graph image corresponding to the type. Figure 7 It is a figure which shows the projection situation of 2nd Example. The student 40 draws an input object on the screen 11 using the electronic pen 60 .

[0046] Figure 8 is a functional block diagram of the projector 101 of the second embodiment. The projector 101 has the same configuration as the projector 100, but differs from the projector 100 in that the detection unit 131 included in the image generation device 103 detects a type object representing a type of graph from the input object data 122, and represents the type of the graph. The storage unit 121 stores the category object data 125 of the category.

[0047] Figure 9 is a diagram showing an input object 401 of the second embodiment. The contents of the graph area 411 and the data area 421 in the input object 401 are the same as tho...

Abstract

A projector includes: a detecting unit that detects, from input object data indicating contents of an input object input by handwriting, graph object data indicating an drawing area for a graph and data object data indicating data for forming a graph; and an image generating unit that generates, on the basis of the graph object data and the data object data, an image including the graph in the drawing area.

Description

technical field [0001] The present invention relates to an image generating device, a projector, a program, and an image generating method. Background technique [0002] For example, in a classroom, a student or a teacher writes characters on a whiteboard with an electronic pen while an image is displayed on the whiteboard. For example, Japanese Patent Application Laid-Open No. 2011-2650 describes the use of a PC (Personal Computer) and a projector to generate and project a synthetic trajectory including a trajectory corresponding to the position of infrared light emitted from the front end of a pointing device and captured by a camera. image. A chart may be drawn by hand on a whiteboard or the like using such a pointing device such as an electronic pen, an ink pen, or the like. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2011-2650 [0004] However, it takes time for the user to draw the diagram by hand, and it does not look pretty. In addition, a method in...
