## Abstract

A display device includes: a first video signal input unit that receives a first video signal; a second video signal input unit that receives a second video signal; a video signal rotating unit that converts the first video signal so that an image based on the first video signal rotates, to obtain a converted video signal; a video combining unit that combines the second video signal with the first converted image signal to obtain a combined video image signal; and a display unit that displays a combined video image based on the combined image signal.

## Claims

### Claim 1

A display device comprising:
a first video signal input unit that receives a first video signal;
a second video signal input unit that receives a second video signal;
a video signal rotating unit that converts the first video signal so that an image based on the first video signal rotates, to obtain a converted video signal;
a video combining unit that combines the second video signal with the first converted image signal to obtain a combined video image signal; and
a display unit that displays a combined video image based on the combined image signal.

### Claim 2 (depends on 1)

The display device according to claim 1, further comprising:
a posture detecting unit that detects a posture of the display unit,
wherein the video signal rotating unit detects an orientation of the image based on the first video signal, and converts the first video signal based on the detected posture and the detected orientation.

### Claim 3 (depends on 1)

The display device according to claim 1, wherein the video signal rotating unit converts a coordinate of the image based on the first video signal so that a display position of an image based on the converted image signal is substantially the same as a display position of the image based on the first image signal when seen from a user.
