Abstract
A method comprising: obtaining a disparity map for one of a left eye image and a right eye image, the disparity map indicating the horizontal displacement between corresponding pixels in the left eye image and the right eye image; generating a luminance representation of the disparity map, wherein a disparity unit which defines the resolution of the disparity map, is mapped to a corresponding luminance value; and companding the luminance value for transmission over a luminance channel is described.
Claims14
A method comprising:
- obtaining, by circuitry, a disparity map for one of a left eye image and a right eye image, the disparity map indicating the horizontal displacement between corresponding pixels in the left eye image and the right eye image;
- generating, by the circuitry, a luminance representation of the disparity map, wherein a disparity unit which defines the resolution of the disparity map, is mapped to a corresponding luminance value;
- companding, by the circuitry, the luminance value for transmission over a luminance channel;
- generating, by the circuitry, an error signal, the error signal being the difference between the companded luminance value and the luminance value;
- and
- converting, by the circuitry, the error signal for transmission over a chrominance channel.
