Abstract: An image correcting method of the present invention includes: a step of performing a preprocessing process on an original image to generate a mask image including only an erased area of the original image; a step of predicting, by using generative adversarial networks, an image which is to be synthesized with the erased area in the mask image; and a step of synthesizing the predicted image with the erased area of the original image to generate a new image.

Abstract: A lens module includes a first lens barrel in which at least one lens is disposed and including a first threaded portion and a first stepped portion on an outer circumferential surface of the first lens barrel; and a second lens barrel in which at least one lens is disposed and including a second threaded portion and a second stepped portion on an inner circumferential surface of the second lens barrel, wherein the first lens barrel and the second lens barrel are coupled to each other by fitting the first stepped portion and the second stepped portion to each other and screwing the first threaded portion and the second threaded portion to each other.

Abstract: The present invention relates to an auto-focusing optical system, and more particularly, to an auto-focusing optical system for a camera module, capable of obtaining a high resolution in a small size using a liquid lens whose curvature is varied depending on an applied voltage. In the auto-focusing optical system, a first lens group has a liquid lens whose curvature is varied and having a plus optical power, a second lens group has a plus optical power, and a third lens group has a minus optical power. Thanks to an auto-focusing optical system including a liquid lens according to the present invention, not only a manufacturing in a small size is possibly realized but also a high resolution can be obtained, and power consumption is small.
