Provided are a noise reduction apparatus having an edge enhancement function and a method thereof, in which edges in an input image can be prevented from being blurred when reducing noise in the input image and a clear output image can be obtained by reducing edge discontinuities. The noise reduction apparatus includes a window setting module which sets a portion of an input image as a window, an edge-information detection module which detects edge information regarding the window, an image processing module which performs an image processing operation on the window, and an output-image generation module which generates an output image by reflecting the edge information into one or more windows obtained by the image processing operation.

An image sensing apparatus, particularly, an apparatus for optically combining visible images with far-infrared images is provided in which performing a separate signal processing may not be needed. The image combining apparatus emits light that is sensed by an image sensor, and reflects the light toward the image sensor in response to far-infrared rays being sensed from an object, thereby converting far-infrared information into information that can be sensed by the image sensor.

A method of and apparatus for converting a color space. The method includes: separating a color signal of a given pixel into a brightness component and a saturation component; obtaining a boundary value of the saturation component of a color gamut, to which the color signal belongs, in a first color space using the separated brightness component and saturation components; and converting the first color space into a second color space in which saturation components and hue components are independently controlled using the obtained boundary value.
