Abstract: PURPOSE: An apparatus and a method for adjusting a focus using a modulation transfer function of a lens in a digital image processing device are provided to adjust a focus by shifting a focus peak value as much as a compensation value, thereby obtaining a high quality image in which a focus is adjused. CONSTITUTION: A digital signal processor(39) comprises the following units. A focus value calculator(39-1) calculates focus values according to focus lens movement. A focus compensator(39-2) calculates a defocus compensation value from MTF data. The focus compensator calculates an actual focus peak value. A focus motor controller(39-3) corrects a focus location.

Abstract: An auto focus system and an auto focus method using the same are provided to obtain a reliable auto focus signal by using an IR signal even under a low brightness condition. A lens unit(202) includes a plurality of lenses. An IR cut filter(203) is arranged on an optical axis. An iris(204) is arranged on the optical axis. A photographing device(205) photographs an image of a subject passed through the lens unit and the iris. An IR cut filter driving unit(206) is connected to the IR cut filter. The IR cut filter is selectively located on the optical axis according to the brightness around the subject by the IR cut filter driving unit.

Abstract: A digital image processing apparatus having an automatic backlight detection function is provided to calculate the range of an incident angle of the sun and a backlight area based on location information, time information, and direction information received to a GPS receiver and an electron compass and determine backlight, thereby reducing conspicuously failure and an error caused by the manual determination of backlight. A unit(192) for deriving the incident angle of the sun derives the incident angle of the sun from the location information and time information of a digital image processing apparatus. A backlight area calculation unit(193) calculates the range of a backlight area from the direction information of the digital image processing apparatus. A backlight determination unit(194) determines whether the photographic direction of the digital image processing apparatus is backlight or not from the incident angle of the sun and the range of the backlight area.
Abstract translation: 提供一种具有自动背光检测功能的数字图像处理装置，用于基于接收到GPS接收机和电子罗盘的位置信息，时间信息和方向信息来计算太阳和背光区域的入射角的范围，并确定 背光，从而减少明显的故障和由背光手动确定引起的错误。 用于导出太阳入射角的单元（192）根据数字图像处理装置的位置信息和时间信息导出太阳的入射角。 背光区域计算单元（193）根据数字图像处理设备的方向信息计算背光区域的范围。 背光判定单元（194）根据太阳的入射角度和背光区域的范围，判定数字图像处理装置的拍摄方向是背光还是背光。
