DIGITAL IMAGE PROCESSING APPARATUS AND METHOD OF CONTROLLING THE SAME

摘要

Provided are a digital image processing apparatus capable of photographing an image of which an ISO sensitivity-to-noise ratio is improved by adjusting a size of the image to be photographed in low light conditions, and a method of controlling the digital image processing apparatus. The method includes the operations of receiving an input image; measuring input brightness of the input image; determining whether the input brightness is lower than an appropriate brightness; and generating an intermediate image by reducing a size of the input image by using an add mode for each pixel if the input brightness is lower than the appropriate brightness.
