<p>PROBLEM TO BE SOLVED: To provide an image-capturing device for realizing a high magnification zoom function.SOLUTION: An image-capturing device 1 comprises a first lens group 10 including a first liquid crystal lens 11, a second lens group 20 including a second liquid crystal lens 21, a third lens group 30 including a fixed lens, and an image-capturing element for receiving light having passed through the third lens group 30 and converting the received light into an electric signal. The first lens group 10, the second lens group 20, and the third lens group 30 are positioned relative to each other, and are arranged so that light passes through the first lens group 10, the second lens group 20, and the third lens group 30 in the order stated. A first group principal pint M1 which is the principal point of the first lens group 10, a second group principal pint M2 which is the principal point of the second lens group 20, and a third group principal pint M3 which is the principal point of the third lens group 30 are located on the same optical axis, a distance between the first group principal pint M1 and the second group principal pint M2 being longer than a distance between the second group principal pint M2 and the third group principal pint M3.</p> |
