Device, Method and Computer Program for Generating a Synthesized Image

A method of generating a synthesized image representing a view of a scene from a first input image representing the view and a second input image representing the view, the synthesized image comprising synthesized image positions, by assigning a synthesized image data value to a synthesized image position, comprising:

• determining whether the first input image has a first image data value assigned to a first input image position of the first input image corresponding to the synthesized image position;
• determining whether the second input image has a second image data value assigned to a second input image position of the second input image corresponding to the synthesized image position;
• assigning the first image data value to the synthesized image position if the first image position has the first image data value assigned to it and the second image position has no image data value assigned to it;
• assigning the second image data value to the synthesized image position if the second image position has the second image data value assigned to it and the first image position has no image data value assigned to it;
• assigning a synthesized image data value to the synthesized image position if the first input image position has a first image data value assigned to it and the second input image position has a second image data value assigned to it, determining of the synthesized image data value comprising:
• determining a distance between the synthesized image position and a further image position where a corresponding further first input image position or a corresponding further second input image position does not have an image data value assigned to it;
• and
• calculating the synthesized image data value by calculating a weighted average of the first image data value and the second image data value, the weighting being a weighting function of the determined distance.
