Title: PHOTOGRAPHIC DEVICE AND IMAGE CAPTURE METHOD UTILIZING SAME
Abstract:
A photographic device and an image capture method utilizing the same. The photographic device comprises a liquid crystal lens array comprising a plurality of sub-liquid crystal lenses, an image sensor, and a driving module. A distance is preconfigured between the liquid crystal lens array and the image sensor, and the liquid crystal lens array is electrically connected to the driving module. In a capture duration, the driving module is configured to adjust, according to distances between objects to be photographed and corresponding sub-liquid crystal lenses, focuses of the sub-liquid crystal lenses, so as to focus, via the corresponding sub-liquid crystal lenses, light rays from the objects, on a plane of the image sensor. In the embodiment, the driving module can adjust the sub-liquid crystal lenses to have different focuses, to provide clear focuses of images of objects to be photographed and located at different distances, thereby acquiring a deep focus image. In comparison to the conventional deep focus photographic device, the photographic device has the advantages of being simple in structure, quick in response, requiring no post-processing, and being easy to operate.
