20080304816 | Camera shaking correcting device, and image pickup device - Output of a gyro sensor is read at intervals of control time ts, time integration is carried out, an integrated value is computed, and an amount of change in an integrated value is determined from a difference between the calculated integrated value and an integrated value of a previous time. Thereafter, on the basis of the amount of change and a delay time determined by a shaking correcting module and the control time, an addition value (an acceleration value of an integrated value of the current time) is computed in order to obtain an amount of movement of a shift lens which can compensate tilting of an optical axis of a lens. After the computed addition value is added to the integrated value of the current time, a control value for moving the shift lens is computed by using the integrated value after addition. | 12-11-2008 |

20090028536 | APPARATUS AND METHOD FOR MEASURING AN ACCELERATION TO DETERMINE A CAMERA DOME'S REQUIRED MOTOR HOLDING CURRENT - A system and method for reducing vibration in a dome camera security system is provided in which the heat produced by the motors is reduced as well. The dome camera system is equipped with an acceleration detecting circuit disposed in close proximity to the camera. The acceleration detecting circuit has an accelerometer for detecting accelerations in any of three directions (i.e., X-axis, Y-axis and Z-axis). As a vibration is induced on the camera by external forces, such as wind or traffic, the acceleration detection circuit detects accelerations indicative of the vibrations and in proportion to the magnitude of the vibration on the camera. A controlling circuit adjusts the holding current of the motors in response to the detected accelerations, thereby increasing the ability of the motors to maintain a particular camera position. When vibrations are detected to be minimal or not present, the holding current can be reduced thus reducing heat production by the motors. | 01-29-2009 |
