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

Patent number: 7640134Abstract: A step detecting apparatus and method in a personal navigator where acceleration signals in at least two directions are acquired from an accelerometer sensor, as a pedestrian moves. Variances of the acceleration signals are calculated and summed. The variance sum is compared with a threshold. If the variance sum is greater than the threshold, it is determined that a detected step is a walking step. If the variance sum is less than the threshold, it is determined that the detected step is a mark-time step.Type: GrantFiled: September 18, 2006Date of Patent: December 29, 2009Assignees: Samsung Electronics Co., Ltd, Seoul National University Industry FoundationInventors: Kyong-Ha Park, Hyun-Su Hong, Jae-Myeon Lee, Chan-Gook Park, Jin-Won Kim

Publication number: 20080120062Abstract: An apparatus and method for estimating a step length of a user are provided. The apparatus and method use a step length estimation algorithm, e.g. a step length estimation parameter coefficient, according to a movement state of a user, i.e. whether the movement state is a walking state or a running state. The movement state of the user is determined on the basis of an acceleration variance value of an acceleration signal output from an accelerometer. Accordingly, the apparatus and method prevent errors in step length determinations.Type: ApplicationFiled: October 31, 2007Publication date: May 22, 2008Applicants: SAMSUNG ELECTRONICS CO., LTD., SEOUL NATIONAL UNIVERSITY INDUSTRY FOUNDATIONInventors: Jae-Myeon LEE, Hyun-Su HONG, Chan-Gook PARK, Jin-Won KIM, Kyong-Ha PARK, Ji-Heon OH

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
