1. Method for generating an intermediate image from stereo data for an intermediate view, using a mixing of a left intermediate image and a right intermediate image according to a mixing policy that defines relative contributions of the left and right intermediate image in the mixing as a function of the intermediate view, the stereo data comprising a left data and a right data, the left data comprising a left image and a left disparity data, the left data corresponding to a left view, the right data comprising a right image and a right disparity data, the right data corresponding to a right view, and the intermediate image corresponding to an intermediate view, the left intermediate image generated from the left data for the intermediate view, the right intermediate image generated from the right data for the intermediate view, the method comprising: predicting the image quality of the intermediate image for each of a plurality of mixing policies based on an image characteristic of the stereo data, a mixing policy defining relative contributions of the left and right intermediate images in the mixing and an image characteristic being one or more of the amount of detail of the stereo data, artifacts, blur, detail sharpness and ghosting; determining, the mixing policy by selecting a mixing policy from the plurality of mixing policies based on a predicted image quality of the intermediate image; and when the determined mixing policy so requires, generating the left intermediate image when the determined mixing policy so requires, generating the right intermediate image and generating the intermediate image by mixing the left intermediate image and the right intermediate image, using the relative contributions according to the determined mixing policy.
