Claims

An imaging device comprising: an operation means for inputting an operation instruction; a control means for controlling zoom drive during exposure in response to the operation instruction from the operation means; and a storage means for storing time data.
The control means drives the focus adjustment lens to the first focus position, starts driving the lens related to zoom control after the drive, and based on the time data stored in the storage means By driving the focus adjustment lens to the second focus position and then starting the exposure operation, the focus adjustment lens is driven while avoiding the duration of the inrush current that occurs during zoom drive. An imaging device that is characterized.

The control means is
Zoom control means for controlling the focal length;
Exposure control means for controlling the exposure time;
In-focus control means for controlling the in-focus position,
Performing drive control to the first in-focus position by the in-focus control means in the first operation by the operation means;
After the operation of the zoom control unit is started by the second operation by the operation unit and the duration time has elapsed, the focus control unit performs drive control to the second focus position, The imaging apparatus according to claim 1, wherein the operation of the exposure control unit is started.

In the drive control to the second focus position by the focus control means, the zoom control is performed for a period corresponding to the sum of the duration and the time required for drive control to the second focus position. The imaging apparatus according to claim 1, wherein the movement amount of the focal length due to the operation of the means is corrected.

2. The image pickup apparatus according to claim 1, wherein zoom driving is continued until an exposure operation ends after an exposure time elapses after the exposure operation is started.

The control means controls the focus adjustment lens to follow the focus position according to the amount of movement of the focal length by the zoom drive after starting the exposure operation. The imaging device according to claim 1.

The imaging apparatus according to claim 5 , wherein the control unit ends the tracking operation of the focus adjustment lens to the in-focus position before the exposure operation ends.

An imaging apparatus comprising: an operation unit for inputting an operation instruction; and a control unit that receives the operation instruction from the operation unit and controls to provide an exposure time during zoom driving,
The control means includes
Driving the focus adjustment lens to the first focus position by the first operation by the operation means;
During the second operation by the operating means after the first operation,
If the exposure time is shorter than the duration of the inrush current that occurs during zoom drive, the focus adjustment lens is moved to the second position after the duration of time has elapsed since the start of driving of the lens related to zoom control. After driving to the in-focus position of 2, start the exposure operation,
An image pickup apparatus, wherein when the exposure time is longer than a duration time of an inrush current generated during zoom driving, driving of a lens related to zoom control is started and an exposure operation is started immediately thereafter.

An imaging apparatus comprising: an operation unit for inputting an operation instruction; and a control unit that receives the operation instruction from the operation unit and controls to provide an exposure time during zoom driving,
The control means includes
Controlling the focus adjustment lens to the first focus position by a first operation by the operation means;
During the second operation by the operating means after the first operation,
When the exposure time is shorter than the reference time for determining the length of the exposure time, only the exposure operation is started,
When the exposure time is longer than a reference time for determining the length of the exposure time, driving of the lens related to zoom control is started, and immediately after that, an exposure operation is started. apparatus.

A control means for controlling the zoom drive during exposure in response to an operation instruction, and a control method for an imaging apparatus comprising a storage means for storing time data,
Driving the focusing lens to the first focusing position, and starting driving the lens related to zoom control after the driving;
Based on the time data stored in the storage means, the exposure adjustment is started after the focus adjustment lens is driven to the second focus position. A method for controlling an image pickup apparatus, comprising: a step of driving the focus adjustment lens while avoiding the focus adjustment lens.

An image pickup apparatus control method comprising control means for receiving an operation instruction from an operation means and controlling to provide an exposure time during zoom driving,
Driving the focus adjustment lens to the first focus position by a first operation by the operation means;
During a second operation performed by the operation means after the first operation,
If the exposure time is shorter than the duration of the inrush current that occurs during zoom drive, the focus adjustment lens is moved to the second position after the duration of time has elapsed since the start of driving of the lens related to zoom control. Driving to the in-focus position of 2, and then starting an exposure operation;
In the case where the exposure time is longer than the duration of the inrush current generated during zoom driving, the driving of the lens related to zoom control is started, and the exposure operation is started immediately thereafter. Control method of imaging apparatus.

An image pickup apparatus control method comprising control means for receiving an operation instruction from an operation means and controlling to provide an exposure time during zoom driving,
