摘要： A camera comprising the following components is disclosed: a vibrating motor which drives a focus lens of an image-taking optical system, and a control circuit which controls the vibrating type motor to repeatedly drive and stop the focus lens, extracting higher frequency components from an image signal obtained from an image pickup device in each stopped state of the focus lens, and performing focus adjusting operation of moving the focus lens to an in-focus position in accordance with a focus adjustment state of the image-taking optical system determined on the basis of the higher frequency components. The control circuit causes traveling wave vibration to be generated on the vibrating member of the vibrating type motor when the focus lens is driven and causes standing wave vibration to be generated on the vibrating member while the focus lens is stopped during the focus adjusting operation.

摘要： A camera which drives a focusing lens to a target position in a short period of time while maintaining required stop accuracy in accordance with the status of an image-taking optical system, is disclosed. The camera comprises the image-taking optical system and a pulse generator that outputs pulse signals in accordance with movement of the focusing lens. A stop judging unit selectively carries out, in accordance with the status of the image-taking optical system, a first stop judgement of the focusing lens by detecting that the count value of pulse signals has reached a target count value, and a second stop judgement of the focusing lens by detecting that the output signal from the pulse generator does not change.

摘要： A motor control apparatus capable of accelerating the motor speed to a target speed and stabilizing the motor speed in a short time is disclosed. The motor control apparatus includes a speed detection unit which outputs a signal according to the speed of the motor (or movable unit which uses the motor as a drive source). It also includes a control unit which applies, during the acceleration control of the motor to a target speed, an electric brake to the motor when the speed detected based on the signal from the speed detection unit exceeds the target speed.
