Abstract

There is provided an information processing apparatus including an image obtaining unit for obtaining a captured image onto which an emission graphic image including a marker serving as a reference is emitted and a correction information generation unit for generating correction information, for making an emission range and an image capturing range be the same, from a difference between the emission range onto which the emission graphic image is emitted and the image capturing range of the captured image, based on the marker in the captured image and the marker in the emission graphic image.

First claim

What is claimed is:

1. An information processing apparatus, comprising:
an operation information obtaining unit configured to obtain operation information of an operation corresponding to an input by an operator;
an emission control unit configured to:
generate an emission graphic image based on the operation information; and
control emission of the emission graphic image on a first image of a subject;

an image obtaining unit configured to obtain, based on control of an image capturing device, the first image of the subject, wherein the emission graphic image includes a first marker generated based on the operation information that serves as a reference;
a correction information generation unit configured to generate correction information and to correct an emission range and an image capturing range based on the correction information such that the emission range and the image capturing range are same,
wherein the correction information is generated from a first difference between the emission range onto which the emission graphic image is emitted and the image capturing range of the first image, based on a second marker in the first image and the first marker in the emission graphic image; and
a correction unit configured to change a digital zoom ratio based on the correction information and capture a second image of the subject based on the changed digital zoom ratio.

2. The information processing apparatus according to claim 1 ,
wherein the correction unit is further configured to correct the second image based on the correction information such that a range onto which the emission graphic image is emitted and a display range are same; and
a display control unit configured to display the corrected second image on a display device.

3. The information processing apparatus according to claim 2 ,
wherein the correction information generation unit is further configured to generate the correction information from a second difference between a position of the first marker and a predicted position of the second marker and a third difference between a shape of the first marker and a predicted shape of the second marker, based on determination that the emission range and the image capturing range are same.

4. The information processing apparatus according to claim 1 , wherein the correction information generation unit is further configured to detect the second marker from a second difference between a first captured image before the emission of the emission graphic image and a second captured image after the emission of the emission graphic image.

5. An information processing method, comprising:
obtaining, by an operation information obtaining unit, operation information of an operation corresponding to an input by an operator;
generating, by an emission control unit, an emission graphic image based on the operation information;
controlling, by the emission control unit, emission of the emission graphic image on a first image of a subject;
obtaining, by an image obtaining unit, the first image of the subject, wherein the emission graphic image includes a first marker generated based on the operation information serving as a reference;
generating, by a correction information generation unit, correction information and correcting an emission range and an image capturing range based on the correction information such that the emission range and the image capturing range are same,
wherein the correction information is generated from a first difference between the emission range onto which the emission graphic image is emitted and the image capturing range of the first image, based on a second marker in the first image and the first marker in the emission graphic image; and
changing, by a correction unit, a digital zoom ratio based on the correction information and capturing a second image of the subject based on the changed digital zoom ratio.

6. A non-transitory computer-readable medium having stored thereon, computer-executable instructions for causing a computer to execute operations, the operations comprising:
obtaining operation information of an operation corresponding to an input by an operator;
generating an emission graphic image based on the operation information;
controlling emission of the emission graphic image on a first image of a subject;
obtaining the first image of the subject, wherein the emission graphic image includes a first marker generated based on the operation information serving as a reference;
generating correction information and correcting an emission range and an image capturing range based on the correction information such that the emission range and the image capturing range are same, wherein the correction information is generated from a first difference between the emission range onto which the emission graphic image is emitted and the image capturing range of the first image, based on a second marker in the first image and the first marker in the emission graphic image; and
changing a digital zoom ratio based on the correction information and capturing a second image of the subject based on the changed digital zoom ratio.
