Abstract
A light field camera includes a lens module generating a middle image, a light field sensor having a lens array and an image sensor device, and a position adjuster adjusting a position of the light field sensor. The light field camera is between an object side and an image side. The lens array between the lens module and the image side generates a light field image according to the middle image. The image sensor device is arranged at the image side and senses the light field image. When the light field sensor is at a first or second position, the light field image includes a first or second light field sub-image. A relation of a focal length fMLA of the lens array and an exit pupil distance PEXP of the lens module satisfies 0.7 ≤ f MLA P EXP ≤ 1.3 .

A light field camera comprising:
- a lens module is located between an object side and an image side, and configured to generate a middle image;
- a light field sensor comprising:
- a lens array arranged between the lens module and the image side, and generating a light field image according to the middle image;
- and
- an image sensor device arranged at the image side and configured to sense the light field image;
- and
- a position adjuster configured to adjust a position of the light field sensor, wherein when the light field sensor is at a first position, the light field image comprises a first light field sub-image, and when the light field sensor is at a second position, the light field image comprises a second light field sub-image, wherein a relation between a focal length fMLA of the lens array and an exit pupil distance PEXP of the lens module satisfies:
