The first power-voltage detector is actuated at the beginning of sequential shooting before a first image capturing operation starts. The high load image capturing operation starts when the voltage detected by the first power-voltage detector is higher than a first threshold. The low load image capturing operation starts when the voltage detected by the first power-voltage detector is lower than the first threshold. The second power-voltage detector is driven during a high load image capturing operation. The second power-voltage detector is disabled during a low load image capturing operation. | 03-25-2010 |
20100329658 | DIAPHRAGM CONTROL APPARATUS OF INTERCHANGEABLE LENS CAMERA - A diaphragm control apparatus in a camera body includes a stepping motor, a lead screw thereof, wherein a slider is driven by the lead screw, a position detector, and a controller. When the stepping motor is in a free state, the slider allows a diaphragm operatively-associated rod to move to an initial position. The controller detects the slider origin position when the stepping motor is in the free state and drives the stepping motor stepwise to move the slider away from the origin position against a biasing force of a resilient biaser, and drives the stepping motor stepwise to move the slider toward the origin position while detecting the slider position; and sets an initial excitation pattern of the stepping motor upon a distance from the detected slider position to the origin position becoming less than a slider moving distance for one step of the stepping motor. | 12-30-2010 |
20100329659 | DIAPHRAGM CONTROL APPARATUS OF INTERCHANGEABLE LENS CAMERA - A diaphragm control apparatus is provided in a camera body, in which a controller drives a stepping motor to move the slider away from an origin position, thereafter drives the stepping motor in the opposite direction toward the origin position, and thereafter detects the slider position after holding the stepping motor for a first waiting time upon a distance from the slider to the origin position becoming less than slider-moving distance for one step of the stepping motor. The controller causes the stepping motor to enter a free state upon a lapse of the first waiting time and detects the slider position upon a lapse of a second waiting time to set an initial excitation pattern from a difference between the slider position detected during the first waiting time and the slider position detected in the free state thereof and from the moving distance of the slider. | 12-30-2010 |
20100329665 | DIAPHRAGM CONTROL APPARATUS OF INTERCHANGEABLE LENS CAMERA - A diaphragm control apparatus in a camera body includes a stepping motor; a lead screw thereof, wherein a slider is driven by the lead screw; a position detector; and a controller. When driving the stepping motor by a predetermined number of steps in a direction to move the slider away from an origin position, the controller detects the slider position before driving the stepping motor stepwise as the origin position via the position detector, and thereafter detects a stepping position of the slider to compare the stepping position with the origin position each time the stepping motor is driven by one step, and counts the number of steps based from the moment at which the stepping position of the slider exceeds a predetermined position in the direction to move the slider away from the origin position against the biasing force of the resilient biaser. | 12-30-2010 |
20130195436 | DIAPHRAGM CONTROL APPARATUS OF INTERCHANGEABLE LENS CAMERA - A diaphragm control apparatus is provided with a controller.
