    摘要： An apparatus and method to control the focusing of a photographing device, in which a light source portion is removed from an image, is provided. The focusing of the photographing device is controlled according to whether the image is in a high- or low-illuminance state. The apparatus includes a luminance detection unit detecting respective luminance values of pixels included in an image; a filter unit outputting values corresponding to the detected luminance values; a threshold calculation unit counting a number of pixels having luminance values greater than a predetermined value among the luminance values of the pixels included in the image and calculating a threshold value using a ratio of the counted number of pixels to a total number of pixels included in the image; and a control unit controlling a position of a lens using output values greater than the calculated threshold value among the output values.

    摘要： Provided are an apparatus and method of obtaining a high-quality image by efficiently processing an image obtained at low-light levels. The image obtaining apparatus comprises a sensor which detects a pixel array value by using a color filter including color pixels for obtaining a color image and a reference pixel for obtaining a reference image used for hand-trembling function estimation; an exposure controller which controls exposure times of the color pixels and the reference pixel; and an image generator which generates a long-exposure color image signal and a short-exposure reference image signal from the detected pixel array value, the long-exposure color image signal and the short-exposure reference image signal being aligned with each other. Accordingly, accurate estimation of the hand-trembling function is possible, thereby enabling the high-quality color image restoration.
