Patent number: 7796871Abstract: An apparatus and a method for taking a panoramic photograph are provided. While a lens of the apparatus is rotated, an angular velocity sensor such as a gyroscope outputs an angular velocity and calculates therefrom a rotation angle of the lens. Accordingly, a user can capture sequential image segments for the panoramic photograph at suitable rotation angles. Since unintended rotations due to a user's hand trembling as well as user's intended rotations can be detected, it may be easy to align overlapped portions of adjacent images and thereby to obtain suitable images for panoramic photograph combination. Also, a user can be informed of a capturable section and a rotating direction by using the calculated angular velocity, so the apparatus may promote a user's convenience and without the need for a burdensome tripod.Type: GrantFiled: February 9, 2007Date of Patent: September 14, 2010Assignee: Samsung Electronics Co., LtdInventors: Kyong Ha Park, Hyun Su Hong, Jae Myeon Lee

Publication number: 20070067105Abstract: An apparatus and a method for step detection in a personal navigation system is disclosed. In the apparatus acceleration signals are obtained from an acceleration sensor in a movement direction and a gravity direction relative to a user. Sliding window summing data for the acceleration signals output from the acceleration sensor in the movement direction and the gravity direction are calculated so as to obtain a sum of the sliding window summing data. Then, a zero crossing point is detected based on differential sliding window summing data. A difference of a detection time between a present zero crossing point and a previous zero crossing point is compared with a threshold value, thereby detecting steps of the user based on the distinct signal pattern for walk. The step detection apparatus distinguishes zero crossing detection caused by chattering (e.g.Type: ApplicationFiled: September 18, 2006Publication date: March 22, 2007Applicants: Samsung Electronics Co., Ltd., Seoul National University Industry FoundationInventors: Jae-Myeon Lee, Hyun-Su Hong, Kyong-Ha Park, Chan-Gook Park, Jin-Won Kim
