Abstract

The present disclosure relates to a control apparatus, a control method, and a program, which make it possible to project an image in a wider range appropriately. On the basis of posture information indicative of a posture of a mirror capable of reflecting at least part of projection light outputted from a projection unit for projecting an image content, an image process for compensation to rotate or reverse the image content is performed to the image content. After that, the posture of the mirror in pitch and roll directions is controlled for outputting the image content thus subjected to the image process from the projection unit. The present technology is applicable to a projector with a mirror reflection mechanism, for example.

First claim

1 . A control apparatus comprising:
a compensation process unit configured to perform a compensation process to an image content projected by a projection unit, the compensation process unit performing the compensation process on a basis of posture information indicative of a posture of a mirror configured to be capable of reflecting at least part of projection light outputted from the projection unit; and a control unit configured to control output of the image content from the projection unit, the image content having been subjected to the compensation process by the compensation process unit.

2 . The control apparatus according to claim 1 ,
wherein the compensation process unit performs the compensation process to at least part of the image content in a case where the posture information indicates that the at least part of the projection light for projecting the image content is to be reflected by the mirror.

3 . The control apparatus according to claim 2 ,
wherein, in a case where the posture information indicates that part of the projection light for projecting the image content is to be projected as reflection light reflected from the mirror and remaining part of the projection light is projected as direct light without the reflection by the mirror, the compensation process unit performs the compensation process to an image of the part of the image content that is assigned to the reflection light but not to an image of the remaining part of the image content that is assigned to the direct light.

4 . The control apparatus according to claim 3 ,
wherein the compensation process unit generates a combined image by combining the part of the image content that is assigned to the reflection light and the image of the remaining part of the image content that is assigned to the direct light, and the control unit causes the projection unit to output the combined image.

5 . The control apparatus according to claim 4 ,
wherein the compensation process unit does not perform the compensation process to the image content, in a case where the posture information indicates that the projection light for projecting the image content is projected as the direct light without the reflection by the mirror.

6 . The control apparatus according to claim 4 ,
wherein the compensation process is an image process for rotating or reversing the image content.

7 . The control apparatus according to claim 1 ,
wherein the posture information is information regarding a projection position of the image content.

8 . The control apparatus according to claim 7 ,
wherein the posture information includes information indicative of an angle of the mirror in a pitch direction with respect to a light axis of the projection unit.

9 . The control apparatus according to claim 7 ,
wherein the posture information includes information indicative of an angle of the mirror in a roll direction with respect to a light axis of the projection unit.

10 . The control apparatus according to claim 1 ,
wherein the control unit performs control to change a posture of the mirror according to a projection position of the image content.

11 . The control apparatus according to claim 10 ,
wherein the control unit performs control to change the posture of the mirror in a pitch direction with respect to a light axis of the projection unit.

12 . The control apparatus according to claim 10 ,
wherein the control unit performs control to change the posture of the mirror in a roll direction with respect to a light axis of the projection unit.

13 . The control apparatus according to claim 1 , further comprising:
an environment recognition unit configured to recognize, as usage environment for the projection unit, a user who is to view the image content and a projection surface to which the image content is to be projected.

14 . A control method, wherein a control process apparatus configured to control projection of an image content comprises:
performing a compensation process to the image content on a basis of posture information indicative of a posture of a mirror configured to be capable of reflecting at least part of projection light outputted from a projection unit configured to project the image content; and controlling output of the image content from the projection unit, the image content having been subjected to the compensation process.

15 . A program for causing a computer of a control process apparatus to perform a process, the control process apparatus being configured to control projection of an image content, the process comprising:
performing a compensation process to the image content on a basis of posture information indicative of a posture of a mirror configured to be capable of reflecting at least part of projection light outputted from a projection unit configured to project the image content; and controlling output of the image content from the projection unit, the image content having been subjected to the compensation process.
