Stereoscopic display device and display method of stereoscopic display device
View Patent ↗A stereoscopic display device includes: a parallax adjustment section performing a parallax adjustment on each of a left-eye image and a right-eye image which are inputted; and a display section displaying the left-eye image and the right-eye image which are resultant of the parallax adjustment by the parallax adjustment section. The parallax adjustment section performs the parallax adjustment only on a region other than an OSD image region with an OSD image superposed therein in each of the left-eye image and the right-eye image.
1. A stereoscopic display device, comprising:
parallax adjustment circuitry configured to receive a left-eye image and a right-eye image and perform a parallax adjustment on the left-eye image and the right-eye image, each one of the left-eye image and the right-eye image including a first region and a second region, the first region being an On-Screen Display (OSD) image region; and
display circuitry configured to display an adjusted left-eye image and an adjusted right-eye image which are resultant of the parallax adjustment by the parallax adjustment circuitry,
wherein the parallax adjustment circuitry is configured to:
perform the parallax adjustment by, in each one of the left-eye image and the right-eye image,
shifting only the second region of a respective one of the left-eye image and the right-eye image, and
extending the first region of the respective one of the left-eye image and the right-eye image when a section of the second region of the respective one of the left-eye image and the right-eye image adjacent to the first region is lost after performing the shifting.
2. The stereoscopic display device according to claim 1 , further comprising
superimposing circuitry configured to superimpose an OSD image on each of a left-eye image and a right-eye image and generate OSD region information that indicates the OSD image region, and then to supply the parallax adjustment circuitry with the OSD region information as well as the left-eye image and the right-eye image each including the superimposed OSD image,
wherein the parallax adjustment circuitry is configured to determine the second region of the respective one of the left-eye image based on the OSD region information.
3. The stereoscopic display device according to claim 1 , further comprising
input circuitry configured to receive both the left-eye image and the right-eye image as well as OSD region information, the OSD region information indicating the OSD image region,
wherein the parallax adjustment circuitry is configured to determine the second region of the respective one of the left-eye image and the right-eye image based on the OSD region information.
4. The stereoscopic display device according to claim 1 , wherein the parallax adjustment circuitry is configured to extend the first region of the respective one of the left-eye image and the right-eye image by interpolating part of an OSD image that adjoins the lost section of the second region into an area of the lost section.
5. A display method of a stereoscopic display device, the display method comprising:
receiving a left-eye image and a right-eye image each including a first region and a second region, the first region being an On-Screen Display (OSD) image region;
performing a parallax adjustment by, in each of the left-eye image and the right-eye image,
shifting only the second region of a respective one of the left-eye image and the right-eye image, and
extending the first region when a section of the second region of the respective one of the left-eye image and the right-eye image adjacent to the first region is lost after performing the shifting; and
displaying an adjusted left-eye image and an adjusted right-eye image which are resultant of the parallax adjustment.
6. The stereoscopic display device according to claim 1 , wherein the parallax adjustment includes changing a parallax between the left-eye image and the right-eye image.
7. The stereoscopic display device according to claim 1 , wherein the parallax adjustment includes increasing a parallax between the left-eye image and the right-eye image.
8. The stereoscopic display device according to claim 1 , wherein the parallax adjustment includes increasing a parallax between the left-eye image and the right-eye image from a first value greater than zero to a second value.
9. The stereoscopic display device according to claim 1 , wherein the parallax adjustment circuitry is configured to perform the parallax adjustment linearly in an extended section of the first region.
10. The stereoscopic display device according to claim 1 , wherein an extended section of the first region has a width corresponding to a magnitude of a parallax between the left-eye image and the right-eye image.
