A photographing method and apparatus are provided. In the method, an image signal of an object region is detected from an input image signal, a shadow region is detected from the object region image signal, and an image signal obtained by superimposing the shadow region on the object region image signal is displayed. When removal of a shadow is requested after the input image signal is captured, the photographing method corrects a brightness level of the shadow region. The photographing apparatus includes an object region detecting unit configured to detect an image signal of an object region from an image signal; a shadow region detecting unit configured to detect a shadow region from the object region image signal, and an image signal superimposing unit configured to output an image signal detected by superimposing the shadow region detected by the shadow region detecting unit onto the object region image signal detected by the object region detecting unit.

A color signal processing apparatus calculates a target color gamut including color signal values of each pixel of an input video, and calculates target primary colors corresponding to the calculated target color gamut. The color signal processing apparatus produces the calculated target primary colors by mixing primary colors in an input color gamut of the input video, and converts and outputs the color signal values of each pixel of the input video to match the calculated target color gamut defined by the calculated target primary colors. Since it is possible to adaptively transform the input color gamut of the input video, the input video that is reproduced has an increased light quantity and an enhanced contrast.

Color signal display apparatus and method

A method of controlling an imaging apparatus and an imaging apparatus using the same are provided, wherein the method controls the imaging apparatus including an image sensor that performs an electronic shutter function by calculating a moving characteristic of a mechanical shutter based on an amount of electric charge accumulated in a first area and an amount of electric charge accumulated in a second area, and controlling the electronic shutter function of the image sensor based on the calculated moving characteristic of the mechanical shutter. Accordingly, the performance of the imaging apparatus using a focal plane shutter can be improved.

Method of controlling imaging apparatus and imaging apparatus using the same

Provided are an apparatus and a method for compensating signal distortion caused by noise. The apparatus comprises a noise reduction unit which reduces noise of an input signal including non-zero mean random noise, and a signal compensator which compensates the output signal of the noise reduction unit so that a signal distortion due to the non-zero mean random noise is removed from the output signal of the noise reduction unit.
