Projector system, and method for drawings

摘要

When a user or the like blocks a portion of a projected image, acquisition of position information about a drawing-designated position, which is designated using a pointing device, is inhibited, and a missing drawn portion is produced. However, a projection apparatus generates image data that is interpolated using a pattern image, thereby making it possible to draw a graphic object as drawn.

主权项

1. A projection apparatus that performs projection onto a projection surface, the projection apparatus comprising:
a receiving unit that receives drawing position information and drawing request information transmitted from a drawing device for projecting image data onto the projection surface, the drawing position information indicating a drawing designated position on the projection surface, the drawing request information requesting that drawing be performed; a first generating unit that generates the image data to be projected onto the projection surface using the drawing position information that is received in a receiving period, over which the drawing request information is being received; a judgement-value calculating unit that calculates a drawing failure period, over which the drawing position information is not received in the receiving period; a pattern storage unit that stores multiple types of pattern images; a second generating unit that generates interpolation image data of a portion corresponding to the drawing failure period using one pattern image of the pattern images, the one pattern image being similar to the image data generated by the first generating unit; a projecting unit that projects the image data generated by the first generating unit interpolated with the interpolation image data generated by the second generating unit; and an interpolation determining unit that determines whether or not to generate the interpolation image data by interpolating a missing drawn line portion corresponding to the drawing failure period, based on a value of the drawing failure period, wherein when the interpolation image data is determined to be generated by interpolating the portion, the second generating unit generates the interpolation image data of the portion using the one pattern image similar to the image data generated by the first generating unit.
