Abstract

There is provided a reproducing apparatus that includes a separating unit operable to separate a three-dimensional image signal containing left-eye image data and right-eye image data into left-eye image data and right-eye image data, a decoder operable to decode the left-eye image data to output a left-eye image signal, and decode the right-eye image data to output a right-eye image signal, a first image quality adjustment unit operable to adjust image quality of an image indicated by the left-eye image signal, and a second image quality adjustment unit operable to adjust image quality of an image indicated by the right-eye image signal. Adjustment of the image quality of the image indicated by the left-eye image signal, which is performed by the first image quality adjustment unit, is performed independently from adjustment of the image quality of the image indicated by the right-eye image signal, which is performed by the second image quality adjustment unit.

Claims

1. A reproducing apparatus comprising:

a separating unit operable to separate a three-dimensional image signal containing left-eye image data and right-eye image data into left-eye image data and right-eye image data;

a decoder operable to decode the left-eye image data to output a left-eye image signal, and decode the right-eye image data to output a right-eye image signal;

a first image quality adjustment unit operable to adjust image quality of an image indicated by the left-eye image signal; and

a second image quality adjustment unit operable to adjust image quality of an image indicated by the right-eye image signal;

wherein adjustment of the image quality of the image indicated by the left-eye image signal, which is performed by the first image quality adjustment unit, is performed independently from adjustment of the image quality of the image indicated by the right-eye image signal, which is performed by the second image quality adjustment unit.

2. The reproducing apparatus according to claim 1, wherein the first and second image quality adjustment units adjust the image qualities so that the image quality of the image indicated by the left-eye image signal is identical to the image quality of the image indicated by the right-eye image signal are identical.

3. The reproducing apparatus according to claim 1, wherein one of the left-eye image data and the right-eye image data of the three-dimensional image signal is base image coded data which is obtained by coding a base image, and the other image data is extension image coded data which is obtained by coding information about difference between the left and right eye images.

4. The reproducing apparatus according to claim 3, wherein each of the first and second image quality adjustment units includes a section operable to remove noise from the image signals, and wherein noise removal intensity for the image signal decoded from the extension image data is higher than that for the image signal decoded from the base image data.

5. The reproducing apparatus according to claim 3, wherein the adjustment of the image quality of the image indicated by the image signal decoded from the base image coded data, made by the first or second image quality adjustment unit, is identical to adjustment of image quality of an image indicated by a two-dimensional image signal, made by the first or second image quality adjustment unit.

6. The reproducing apparatus according to claim 1, wherein when the three-dimensional image signal is an image signal of a side-by-side format or top-and-bottom format, either one of the first and second image quality adjustment units makes same image quality adjustment for both the image indicated by the left-eye image signal and the image indicated by the right-eye image signal.
