Title: Camera system
Inventor: MIYAGAWA MASAE
IPC: G02B7/08
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To prevent motor power swing and to perform excellent image observation without generating large image blurs by increasing the drive force of a lens drive means more than the time when moving speed or moving acceleration is lower than a prescribed value, when the moving speed or moving acceleration of a camera is larger than a prescribed value. SOLUTION: When a zoom operation is performed, whether a panning/tilting SW is ON or OFF is confirmed. When the panning/tilting SW is ON, in the case that the speed (or acceleration) of panning/tilting is more than a prescribed value, the system goes into a high torque mode for temporarily increasing an application voltage to a zoom motor 13 and a focus motor 14. Thus, the output torque of the motors 13 and 14 is increased, and if sudden panning or tilting is performed and large acceleration is added to a zoom lens, the power swing of the motors 13 and 14 can be avoided. Therefore, accurate zooming and focusing control are performed.
