Abstract: An object detection system includes: a false detection storer to store one or more items of false detection information; an object detector to detect an object from an input image, compare object detection information corresponding to the object with the false detection information, and output a notification corresponding to the object detection information when false detection information corresponding to the object detection information does not exist; and a feedback receiver to receive a user response to the notification and, when a detection error response to the notification is received, store the object detection information corresponding to the notification as false detection information in the false detection storing unit, wherein the object detector does not output the notification when the object corresponding to the false detection information stored in the false detection storer is detected.

Abstract: A method of adjusting an output bitrate of an image by contrast adjustment includes: determining a maximum subtraction rate of a contrast of the image in response to a brightness of the image; comparing a current output bitrate of the image with a target bitrate while reducing the contrast of the image up to the determined maximum subtraction rate of the contrast of the image; and determining the contrast of the image to be the reduced contrast in response to determining that the reduced contrast of the image corresponds to the target bitrate.

Abstract: A zoom lens system includes: a first lens group having a positive refractive power; a second lens group having a negative refractive power; a third lens group having a positive refractive power; a fourth lens group having a positive refractive power; a fifth lens group having a positive refractive power; and a sixth lens group having a positive refractive power, wherein the first to sixth lens groups are sequentially arranged along an optical axis from an object side to an image plane side, and zooming is performed by moving at least one of the second lens group, the fourth lens group and the fifth lens group along the optical axis. A distance between a focal point of light having a first wavelength and a focal point of light having a second wavelength is about 50 μm or less at a wide-angle position and a telephoto position. The first wavelength corresponds to green light, the second wavelength corresponds to near infrared (NIR) light.

Abstract: Provided is an image processing apparatus which generates a wide dynamic range (WDR) image using an image sensor. The image processing apparatus includes: an image sensor which outputs image data having a plurality of image channels; a mode setting unit which changes a photographing mode from a first mode in which a first number of sub-images are synthesized to a second mode in which a second number of sub-images are synthesized, based on luminance of the output image data; a register setting unit which changes a register value of the image sensor according to the second mode; and an image signal processor (ISP) which generates a result image by synthesizing the second number of sub-images from the image data according to the changed register value, wherein the second number of sub-images have different exposure times.
