View synthesis is performed based on obtained texture data and a depth map. The resolution of the depth map is lower than that of the texture data by a ratio dw in the x direction and by a ratio dh in the y direction. Texture pixel positions x, y are transformed into non-integer depth map pixel positions by performing divisions x/dw and y/dh and these non-integer depth map pixel positions are rounded to integer depth map pixel positions, and a view is synthesized based at least on the obtained texture data and depth map values at the integer depth map pixel positions and/or adjacent positions.

View synthesis using low resolution depth maps

Sparseness is reduced in an input digital signal which includes a first sequence of sample values. An output digital signal is produced in response to the input digital signal. The output digital signal includes a second sequence of sample values, which second sequence of sample values has a greater density of non-zero sample values than the first sequence of sample values.
