Abstract
An image-taking control apparatus lets the operations of a plurality of drivable parts, including a first drivable part whose driving speed can be switched only in steps, finish substantially simultaneously. A speed selector selects an operation speed for each of the drivable parts, based on its current position, its target position, and a target operation time. A controller performs lets the operation of the first drivable part start when a waiting time corresponding to a difference between the anticipated operation time for the selected operation speed and the target operation time has passed after a start command time.
Claims10
An image-taking control apparatus controlling a plurality of drivable parts of an image-taking device, the plurality of drivable parts including a first drivable part whose operation speed can be selected only in steps, such that operations of the respective drivable parts from their current positions to their target positions finish substantially simultaneously, the image-taking control apparatus comprising:
- a speed selector selecting an operation speed for each of the drivable parts, based on information on its current position, information on its target position, and information on a target operation time from a start command time at which an operation start of the plurality of drivable parts is commanded until the respective operations to the target positions finish;
- and
- a controller performing such control that each of the drivable parts operates at its operation speed selected by the speed selector;
- wherein the speed selector selects a specific operation speed for the first drivable part from selectable operation speeds of the first drivable part, the specific operation speed being an operation speed at which the operation to the target position can finish within the target operation time;
- and
- wherein the controller calculates an anticipated operation time needed until the operation of the first drivable part to its target position at the specific operation speed finishes, and lets the operation of the first drivable part start when a waiting time corresponding to a time difference between the anticipated operation time and the target operation time has passed after the start command time.
The image-taking control apparatus according to claim 7,
- wherein the plurality of drivable parts includes the first drivable part and a second drivable part whose operation speed can be selected in non-steps.
