PROJECTION APPARATUS, PROJECTION SYSTEM, AND PROJECTION METHOD
First Claim
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; and
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.

Abstract
A projection apparatus includes: a receiving unit that receives, from a drawing device, drawing position information indicating a drawing designated position on a projection surface and drawing request information; a first generating unit that generates image data to be projected onto the projection surface using the drawing position information 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 of the pattern images that is similar to the image data; and a projecting unit that projects the image data interpolated with the interpolation image data.

20. A projection method that performs projection onto a projection surface, the projection method comprising:
-
receiving, by a receiving unit, 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; generating, by a first generating unit, 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; calculating, by a judgement-value calculating unit, a drawing failure period, over which the drawing position information is not received in the receiving period; storing, by a pattern storage unit, multiple types of pattern images; generating, by a second generating unit, 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; and projecting, by a projecting unit, the image data generated by the first generating unit interpolated with the interpolation image data generated by the second generating unit.
