Publication number: 20040061790Abstract: High frequency components of a video signal are attenuated for avoiding aliasing when the video signal is corrected by a non-linear gamma correction circuit. Such high frequency components arise from the video signal harmonics, and also are generated in image contour processing of the video signal. The high frequency components are band limited, thereby linearizing the gamma correction circuit and preventing aliasing. Up-converting the sampling frequency increases a desired band limitation area and defers the generation of high frequency components that cause aliasing. The non-linear gamma correction function is divided into a plurality of sections which are replaced by respective straight-line segments each represented by a linear expression, and gamma correction is effected with a straight-line segment corresponding to the amplitude of the digital video signal.Type: ApplicationFiled: September 30, 2003Publication date: April 1, 2004Applicant: SONY CORPORATIONInventors: Ichiro Tanji, Fumihiko Sudo, Taku Kihara

Publication number: 20040061792Abstract: A mobile telephone is connected to a camera, and their respective power supplies are turned on. A telephone number of the local station is read out and recorded in a flash ROM as registration number data. Moreover, the registration number data is input with image data. As the registration number data is the telephone number of the local station input from the mobile telephone, the image data may be secured without the complex encryption processing of conventional examples. That is, a sense of security may be obtained because forgetting the specific registration number is unlikely when the telephone number of the local station input from the mobile telephone is used as the specific registration number data. Accordingly, the collation procedure becomes easier when the image data is obtained or an order for photo prints is made, and access to the image data may be easily restricted since the image data can be secured without complex encryption processing.Type: ApplicationFiled: February 19, 2003Publication date: April 1, 2004Inventors: Motoari Ota, Tsuneo Sato

Publication number: 20040061793Abstract: A camera incorporates a working memory (124) for storing a working image corresponding to the last captured image. The working image is displayed on a display screen (36) in a quick review mode of operation in response to a quick review signal entered by the camera operator via a camera control interface (74) to control processing circuitry (68,72) of the camera. The processing circuitry controls the display screen to keep it in an inactive state until the quick review signal is entered, and returns it to an inactive state after a predetermined time period or when the quick review signal is discontinued to conserve energy. In addition, the working image is displayed in the quick review mode regardless of whether a non-volatile memory is available in the camera or, in the case of a hybrid camera, whether a film cartridge is contained in a film chamber (98) of the camera.Type: ApplicationFiled: September 30, 2003Publication date: April 1, 2004Inventors: Peter Fellegara, Richard W.

Publication number: 20040061830Abstract: A system (1) is used for contactless measurement of the optical imaging quality of an eye (2) with an interferometer (3) by which at least one light pulse with a short coherence length is coupled into the eye (2) from a light source (10). The optical path length of at least one arm (17) of the interferometer (3) is varied for measuring the length of the eye (2) until a typical interference pattern between a reflection of the cornea (4) and a reflection of the retina (6) of the eye occurs in a detector (4). This interference pattern together with a known path segment of the variation of the optical path length allows conclusions to be made about the length of the eye (2). The variation of the optical path length is carried out by introducing at least partially optically transparent elements (22) and by at least one element (19) of the interferometer (3) which is movable in a defined manner in at least one of the light paths (17) of the interferometer (3).Type: ApplicationFiled: October 1, 2003Publication date: April 1, 2004Inventors: Thomas Hellmuth, Lieng-Chuong Tan

Publication number: 20040061831Abstract: A system for tracking a gaze of an operator includes a head-mounted eye tracking assembly, a head-mounted head tracking assembly and a processing element. The head-mounted eye tracking assembly comprises a visor having an arcuate shape including a concave surface and an opposed convex surface. The visor is capable of being disposed such that at least a portion of the visor is located outside a field of view of the operator. The head-mounted head tracking sensor is capable of repeatedly determining a position of the head to thereby track movement of the head. In this regard, each position of the head is associated with a position of the at least one eye. Thus, the processing element can repeatedly determine the gaze of the operator, based upon each position of the head and the associated position of the eyes, thereby tracking the gaze of the operator.Type: ApplicationFiled: September 27, 2002Publication date: April 1, 2004Applicant: The Boeing CompanyInventors: John H.

Publication number: 20040061834Abstract: A scanning laser polarimetry (SLP) system that measures in vivo retinal nerve fiber layer (RNFL) retardance (&dgr;N, &thgr;N) in a single measurement without a variable corneal compensator (VCC). The diagnostic signal is biased so that the detected RNFL retardance orientation angles are sufficiently similar at adjacent pixels in the retinal polarimetric image to permit resolution of the orientation angle ambiguity in a single polarimetric image without repeating the measurement at another signal polarization state. With a simple bias retarder, the effects of anterior segment retardance (&dgr;C, &thgr;C) can be removed from a single polarimetric image of the retina without a VCC. Alternatively, from two single polarimetric images obtained at two different bias retarder positions, the anterior segment retardance magnitude &dgr;C and orientation &thgr;C and the RNFL retardance magnitude &dgr;N and orientation &thgr;N can all be determined from the peripapillary RNFL image region alone.Type: ApplicationFiled: September 30, 2002Publication date: April 1, 2004Inventors: Qienyuan Zhou, Xiangrun Huang

Publication number: 20040061836Abstract: A highly efficient projection system, including a light source, a scrolling unit, a color separation hologram, a light valve, and a projection lens unit. The scrolling unit includes spirally arranged cylinder lens cells to scroll/cycle incident beams while rotating. The color separation hologram separates a beam radiated from the light source into beams with different wavelengths. The light valve forms a color image by turning on or off pixels according to an input image signal. The projection lens unit magnifies the image formed by the light valve and projects the magnified image toward a screen. In this projection system three color beams from the light source are scrolled simultaneously to produce a picture, resulting in a highly light efficient projection system.Type: ApplicationFiled: August 21, 2003Publication date: April 1, 2004Applicant: Samsung Electronics Co., LTDInventors: Kun-Ho Cho, Dae-Sik Kim, Sung-Ha Kim, Hee-Joong Lee
