Abstract: There is presented a transparent optical device element (700) comprising an optical lens (744), comprising one or more piezoelectric actuators (206, 208, 210), wherein said optical lens (744) comprises an optical aperture (632), and wherein the optical device element furthermore comprises a passivation layer (312, 314, 742, 628) placed on said optical lens, said passivation layer comprising a barrier layer (312)forming a humidity barrier, and being located on at least a portion of said cover member, where said portion of said cover member is intersected by the optical axis, and on said piezoelectric actuators, and wherein the passivation layer furthermore comprises one or more further layers (628) located on at least said portion of said cover member being intersected by the optical axis, wherein said passivation layer forms an anti-reflection coating for said optical lens (744) at least along the optical axis (634).

Abstract: The invention relates to post-processing of a digital photo to correct perspective distortion in the photo. The correction applies a digital photo of a scene and a depth map associated with the photo and comprising, for each pixel in the photo, a depth being a distance between a part of the scene in that pixel and a position of the camera at the time of acquisition. The correction is performed locally, so that the correction of any pixel in the photo depends on the depth of that pixel. The correction can be implemented as a transformation of each pixel in the original photo into a new position in a corrected photo. Afterwards, pixel values has to be calculated for the pixels in the corrected photo using the original pixel values and their new positions. The invention is particularly relevant for photos where objects or scenes involves a large magnification variation, such as selfies, close up photos, and photos when the extension of a large, object is not orthogonal to the optical axis of the camera (low/high angle shots).
