Disclosed are a system and method counting photons. Photons are counted through a plurality of counters. Each of the counters generates a flag signal indicating the availability of each counter for an output of a photon detector. The generated flag signal is input into a control unit which controls a switching unit. The control unit allows a signal to be input into a counter, which is not in dead time, based on the received flag signal.

A method of processing an image is provided. The method includes generating a calibration model by learning an intensity-target data set obtained from a parameter of a test subject; and estimating a target. The estimating includes applying the calibration model to a parameter of an input subject and calibrating the parameter of the input subject.

A method and apparatus for detecting an object are provided. The method calculates a feature value based on features extracted from an input image by using a classifier of an ith stage, compares the calculated feature value with a first threshold value of the ith stage, compares the feature value with a second threshold value of the ith stage according to a result of the comparison between the feature value and the first threshold value of the ith stage, and jumps to a classifier of an i+2th stage according to a result of the comparison between the feature value and the second threshold value of the ith stage. By doing so, the method can avoid repeated calculations and can rapidly detect the object in the input image.

Provided are a method and apparatus for determining whether backlight exists. The method according to an embodiment of the present invention includes calculating scattering degrees of luminance values of pixels included in each of images which represent the same photographic subject and have different brightness levels from each other; and determining whether backlight exists on the photographic subject in consideration of the calculated scattering degrees.

An object-oriented photographing control method, medium, and apparatus. The object-oriented photographing control method includes detecting an interesting object registered in advance from an input image, estimating photographic information on the detected interesting object, and generating control information for capturing the input image by using the estimated photographing information, and capturing the input image according to the control information. Accordingly, states of a position and illuminance of the object are perceived in real-time, a high-quality image can be captured, and the user does not need to control the focus and the exposure of the input image.

Provided are a method and apparatus for recognizing a plurality of faces. In the method, a plurality of faces are detected from received video frames, the detected faces are sequentially recognized in predetermined frames that fall within a predetermined recognition period from among the detected frames, and then, the recognized faces are sequentially displayed. Accordingly, the amount of calculation is less than when simultaneously performing face detection and recognition on each frame.
