Patent Images
1. An apparatus for processing a digital image, the apparatus comprising:
- an image input unit for receiving a plurality of input images from the outside; and
a control unit for;
receiving a plurality of focus images when a first shutter-release button select signal is input from the outside as a focus lens moves along an optical axis, selecting a clearest image from among the focus images as a first best image, and determining a position of the focus lens for the clearest image of the focus images; and
receiving the plurality of input images when a second shutter-release button select signal is input from the outside with the focus lens at the determined position, selecting a clearest image from among the input images as a second best image, and capturing the second best image.

Abstract
An apparatus and appertaining method for controlling the apparatus are provided for processing a digital image, which can capture an image with reduced hand shake effect without using a hand shake sensor. The apparatus includes: an image input unit receiving a plurality of input images from the outside; and a control unit receiving the plurality of input images when a shutter-release button select signal is input from the outside, selecting a clearest image from among the input images as a best image, and capturing the best image.

9. An apparatus for processing a digital image, the apparatus comprising:
-
a focus lens that moves along an optical axis in response to a first shutter-release button select signal to receive a plurality of focus images, and is controlled to be located at a position where a clearest image is obtained from the plurality of focus images; an image input unit for receiving a plurality of input images from the outside when a second shutter-release button select signal is input from the outside while the focus lens remains at the located position; a detection region for detecting unit detecting specific regions of the input images as detection regions; a raw data generating unit for generating raw data of the detection regions from the input images; a luminance value calculating unit for calculating luminance values corresponding to respective pixels from the raw data; a focus value calculating unit for calculating focus values of the input images from the luminance values; and a best image selecting unit for selecting an input image with a highest focus value among the input images as a best image. - View Dependent Claims (10, 11, 12, 13)

14. A method of controlling an apparatus for processing a digital image, the method comprising:
-
receiving a plurality of focus images from the outside as a focus lens moves along an optical axis; determining a position of the focus lens for the clearest image of the focus images; receiving a plurality of input images from the outside while the focus lens remains at the determined position; detecting human regions of the input images as detection regions; receiving raw data of the detection regions; calculating luminance values corresponding to respective pixels from the raw data; calculating focus values of the input images from the luminance values; and selecting an input image with a highest focus value among the input images as a best image. - View Dependent Claims (15, 16)
