Abstract: An embodiment of the disclosure may provide an electronic device. The electronic device may comprise a lens assembly. The lens assembly may comprise a lens group comprising a first lens, a second lens, a third lens, and a fourth lens sequentially arranged along an optical axis O-I in a direction from an object side to an image side, an aperture, and an image sensor comprising an imaging surface (img) on which an image (I) is formed. The first lens may have positive refractive power, the second lens may have negative refractive power, the third lens may have a convex shape toward the image side, and the fourth lens may have negative refractive power. Various other embodiments are possible.

Abstract: An infrared (IR) cut filter includes an absorption type filter, a first coating layer, and a second coating layer. The absorption type filter absorbs IR light of a first wavelength band. The first coating layer is formed on a first side of the absorption type filter and passes visible light and reflects a part of the IR light. The second coating layer is formed on a second side of the absorption type filter and reflects a remaining part of the IR light that passes through the first coating layer and enters the absorption type filter. The absorption type filter further absorbs the IR light of a second wavelength band within the absorption type filter. In addition, a camera module having the IR cut filter is provided and an electronic device having the camera module also is provided.
