Abstract: The present invention provides an effective flicker detection method performing a motion compensation. The present invention includes the steps of: calculating a luminance difference between neighboring pixels; summing up the luminance difference in a specific direction if the difference is greater than a threshold value; performing a motion estimation by using a sum calculated through step (b) to thereby calculate a motion displacement; performing a motion compensation to a current frame data by using the motion displacement; calculating a difference between a previous frame data and the compensated current frame data; and detecting the flicker by using the difference calculated in step (e).

Abstract: A digital image processing apparatus and method for supporting a RAW format (a sensor data format before image processing is performed) selectively supports a user-desired region of a captured image in a RAW format. A method of supporting a RAW format in a digital image processing apparatus includes setting at least one portion of an image displayed in a live-view mode as a region of interest (ROI), storing the ROI in a RAW format, storing a non-ROI of the displayed image, which is a portion of the image other than the ROI, in a compression format, and compositing the stored ROI with the stored non-ROI.

Abstract: A digital photographing apparatus is provided that includes: a lens unit through which image light is transmitted; an image capturing unit for converting the image light transmitted through the lens unit into an image signal; a subject detection unit for detecting a subject from the image signal of the image capturing unit to designate a subject area; a distortion correction unit for converting the image signal into a correction image signal for correcting distortion of the image light caused due to the lens unit, after the subject detection unit has detected the subject; and a subject area converting unit for designating a corrected subject area corresponding to the subject area from the correction image signal.

Abstract: A digital image processing apparatus that supports multi-display to reproduce images on an external display apparatus connectable to the digital image processing apparatus, a method of operating the digital image processing apparatus, and a computer readable recording medium recorded thereon a program for executing the method. The digital image processing apparatus includes: a digital signal processor which, when a signal of a first display command is input to the digital image processing apparatus, displays a screen obtained by performing the first display command on the digital image processing apparatus, and when a signal of a second display command corresponding to the signal of the first display command is input to the digital image processing apparatus, displays a screen obtained by performing the second display command on the external display apparatus.

Abstract: An exemplary image processing method and apparatus, and an exemplary digital photographing apparatus, may develop and display a screen nail image and a face screen nail image rather than a full resolution image. The screen nail image may be generated using RAW data output from an image sensor, a predetermined face region of the screen nail image may be detected, and the face screen nail image may be generated from the screen nail image using coordinates of the detected face region. Thus, power consumption and processing time delay caused by processing all parts of a full resolution image may be minimized, and a quality of the full resolution image may be conveniently checked. As a result, a user may conveniently select and store an image in high-speed still picture photographing.

Abstract: Provided are an apparatus for and method of processing a digital image, specifically, a bracketing apparatus and method for use in a digital image processor, which can reduce a photographing time by calculating focuses for all detected faces by moving a focus motor only once after face detection, and then performing bracketing by compensating the focuses by an interval of the focus motor applied while calculating the focuses of each face. The bracketing apparatus includes a digital signal processor, which detects one or more faces from a live-view image, detects focus values for all detected faces by moving a focus motor only once, and then performs bracketing by compensating a focus by an interval of the focus motor applied while detecting the focus values of each face.

Abstract: A digital photographing apparatus, a method of controlling the digital photographing apparatus, and a recording medium storing a program for implementing the method are provided in a manner by which a user can enjoy maximized convenience in manipulating the digital photographing apparatus. The method includes (a) determining a motion direction of the digital photographing apparatus by analyzing image data obtained from light that is incident on an imaging device; and (b) switching from a current mode of the digital photographing apparatus to another mode corresponding to the motion direction determined in (a).

Abstract: A digital image processing apparatus for significantly reducing an image file size in order to store a large number of image files, a method of controlling the same, a recording medium storing a program for executing the method, and a digital image compressing method. The digital image processing apparatus comprises a sub-image generator for generating a plurality of sub-images from a still image, and a moving image compressor for considering the still image as a moving image by using each of the sub-images as a frame image and compressing the moving image having the frame images.
