Patent number: 6853401Abstract: On a screen G1 of a liquid crystal display, a digital camera displays an AF cursor for use as a focusing point. Thus, a shooter shifts the AF cursor to the portion of a subject to be focused, so as to carry out the setting. Here, when the subject is zoomed up to an enlarged screen G2 through an optical zooming operation, the AF cursor is displayed on the enlarged screen G2, following the subject. Moreover, in the case when the subject is electronically zoomed up to an enlarged screen G3, the AF cursor is also displayed on the enlarged screen G3, following the subject. Thus, even when a zooming process is carried out, it is not necessary to adjust the position of the AF cursor; thus, it becomes possible to improve the operability of the digital camera.Type: GrantFiled: January 7, 2002Date of Patent: February 8, 2005Assignee: Minolta Co., Ltd.Inventors: Shinichi Fujii, Toshiyuki Tanaka, Masahito Niikawa

Patent number: 6851645Abstract: A method and apparatus for finding a relative direction of received radiation is described. The received radiation is incident upon a window system at an angle and is transmitted therethrough. The magnitude of the transmitted radiation decreases as a continuous function of increasing angle of incidence, known as Fresnel transmittance. Opposing radiation detectors then detect this transmitted radiation, thereby creating a pair of detection signals, By dividing the difference of the detection signals by the sum of the detection signals, a processor generates a beta angle error curve and finds the relative direction of the radiation. Based upon this beta angle error curve, the processor generates an appropriate error correction signal for guiding an object based upon the relative direction of the received radiation. The method and apparatus are readily applicable to guiding munitions using a laser monopulse to designate a target.Type: GrantFiled: December 5, 2003Date of Patent: February 8, 2005Assignee: Lockheed Martin CorporationInventors: Brett A. Williams, Brian C. Baker, Mark A. Turner
