Title: IMAGING DEVICE AND IMAGING METHOD
Abstract:
An imaging device (100), comprising a main lens (110), an image sensor (120), and a first micro-lens array (130) and a second micro-lens array (140) both arranged between the main lens and the image sensor. The first micro-lens array is arranged between the second micro-lens array and the main lens; the first micro-lens array and the second micro-lens array are arranged in parallel; the first micro-lens array comprises M*N first micro-lenses; the second micro-lens array comprises M*N second micro-lenses; the M*N first micro-lenses are respectively arranged opposite to the M*N second micro-lenses in a concave-convex manner and correspond to same on a one-to-one basis; if the first micro-lenses are plano-concave lenses, the second micro-lenses are plano-convex lenses; if the first micro-lenses are plano-convex lenses, the second micro-lenses are plano-concave lenses; and a drive device (150) is connected to the main lens, the image sensor, the first micro-lens array and the second micro-lens array for adjusting a distance between the first micro-lens array and the second micro-lens array. Such an imaging device can achieve fast switching between different imaging modes of a camera. Also disclosed is an imaging method.
