Abstract

According to one embodiment, an electronic apparatus is connectable to a projector that projects projection information onto a projection surface to create a projection image and a camera that captures the projection image. The electronic apparatus includes an object detector and a processor. The object detector is configured to detect an object between the projector and the projection surface based on the projection information and captured information from the camera. The processor is configured to perform an object emphasis processing for at least one of the projection information and the captured information.

Claims

1. An electronic apparatus connectable to a projector that projects projection information onto a projection surface to create a projection image and a camera that captures the projection image, comprising:

an object detector configured to detect an object between the projector and the projection surface based on the projection information and captured information from the camera; and

a processor configured to perform an object emphasis processing for at least one of the projection information and the captured information.

2. The electronic apparatus of claim 1, wherein the object emphasis processing comprises an exposure adjustment or a white balance adjustment of the camera such that a difference between an object portion included in the captured information and other portions is emphasized.

3. The electronic apparatus of claim 1, wherein the object emphasis processing comprises a processing of matching a color of the projection information and a color of the captured information.

4. The electronic apparatus of claim 1, wherein the object emphasis processing comprises a processing of increasing a luminance of the projection information.

5. An information processing method of an electronic apparatus connectable to a projector that projects projection information onto a projection surface to create a projection image and a camera that captures the projection image, the method comprising:

detecting an object between the projector and the projection surface based on the projection information and captured information from the camera; and

performing an object emphasis processing for at least one of the projection information and the captured information.

6. A non-transitory computer readable medium having stored thereon a computer program which is executable by a computer, the computer program controlling the computer to execute functions of:

detecting an object between the projector and the projection surface based on the projection information and captured information from the camera; and

performing an object emphasis processing for at least one of the projection information and the captured information.
