An apparatus for evaluating a quality for image capture comprises a stored (101) for storing a model of a scene and a capture circuit (105) for generating virtual captured images for a camera configuration by rendering from the model. A depth generation circuit (107) generates model depth data from the model and a depth estimation circuit (111) generates estimated depth data from the virtual captured images. A first synthesis circuit (109) and a second synthesis circuit (113) generates first and second view images for test poses by processing the virtual captured images based on the model depth data or estimated depth data respectively. A reference circuit (103) generates reference images for the f test poses by rendering based on the model. A quality circuit (115) generates a quality metric based on a comparison of the first view images, the second view images, and the reference images.
