Control apparatus, image pickup system, and storage medium for changing in-focus range
In an image pickup apparatus that can change an in-focus range by driving an aperture stop and changing a tilt angle, the in-focus range can be easily changed. A control apparatus of an image pickup apparatus includes a tilt changing unit that changes a tilt angle that is a relative angle between a lens and an image pickup element and an aperture driving unit that drives an aperture stop. The control apparatus comprises a request unit configured to request the image pickup apparatus to provide any one of at least the tilt angle, an aperture value, and a focus position; and a display controller configured to display an in-focus range of the image pickup apparatus on a display unit, wherein the display controller changes a content to be displayed on the display unit based on the information acquired by the request unit.
1. A control apparatus of an image pickup apparatus including a tilt changing unit that changes a tilt angle that is a relative angle between a lens and an image pickup element and an aperture driving unit that drives an aperture stop, the control apparatus comprising:
a hardware processor; and
a memory for storing instructions to be executed by the hardware processor, wherein, when the instructions stored in the memory are executed by the hardware processor, the control apparatus functions as:
a request unit configured to request the image pickup apparatus to provide any one of at least the tilt angle, an aperture value, and a focus position; and
a display controlling unit configured to cause a display unit to display a graphic showing an in-focus range of the image pickup apparatus based on the tilt angle, the aperture value, and the focus position,
wherein the in-focus range is changed by performing any one of at least rotating, enlarging and/or reducing, and moving the graphic.
2. The control apparatus according to claim 1 ,
wherein the display controlling unit causes the display unit to display an imaging direction or an imaging range of the image pickup apparatus.
3. The control apparatus according to claim 1 ,
wherein, when the instructions stored in the memory are executed by the hardware processor, the control apparatus further functions as a setting unit configured to set any one of at least the tilt angle, the aperture value, and the focus position in the image pickup apparatus, and
wherein the display controlling unit changes the graphic displayed on the display unit based on any one of at least the tilt angle, the aperture value, and the focus position set by the setting unit.
4. The control apparatus according to claim 1 ,
wherein the display controlling unit causes the display unit to display a range in which noise of an image shot by the image pickup apparatus exceeds a predetermined amount together with the graphic, and provides a warning if the in-focus range is changed to a range in which noise exceeds the predetermined amount.
5. The control apparatus according to claim 1 ,
wherein, in acquiring a settable range for each of the tilt angle, the aperture value, and the focus position and performing any one of rotating, enlarging/reducing, and moving the graphic, the display controlling unit causes the display unit to display a possible range for the rotation, the enlargement/reduction, and the moving of the graphic in accordance with the settable range.
6. The control apparatus according to claim 1 ,
wherein the display controlling unit includes a storage unit configured to store settings related to a plurality of in-focus ranges in accordance with a predetermined condition, and sets the in-focus range stored in the storage unit in accordance with the predetermined condition.
7. The control apparatus according to claim 1 ,
wherein the image pickup apparatus includes a distance measurer measuring a distance from the image pickup apparatus to an object, and
wherein the display controlling unit superimposes the in-focus range on an image output from the image pickup apparatus and displays the image having the in-focus range on the display unit.
8. The control apparatus according to claim 1 , further comprising the display unit.
9. A control method of an image pickup apparatus that includes a tilt changing unit that changes a tilt angle that is a relative angle between a lens and an image pickup element and an aperture driving unit that drives an aperture stop, the method comprising:
requesting the image pickup apparatus to provide any one of at least a tilt angle, an aperture value, and a focus position; and
performing display-control by causing a display unit to display a graphic showing an in-focus range of the image pickup apparatus based on the tilt angle, the aperture value, and the focus position,
wherein the in-focus range is changed by performing any one of at least rotating, enlarging and/or reducing, and moving the graphic.
10. A non-transitory storage medium on which is stored a computer program for making a computer execute a method for controlling an image pickup apparatus that includes a tilt changing unit that changes a tilt angle that is a relative angle between a lens and the image pickup apparatus and an aperture driving unit that drives an aperture stop, the method combining:
requesting the image pickup apparatus to provide any one of at least a tilt angle, an aperture value, and a focus position; and
performing display-control by causing a display unit to display a graphic showing an in-focus range of the image pickup apparatus based on the tilt angle, the aperture value, and the focus position,
wherein the in-focus range is changed by performing any one of at least rotating, enlarging and/or reducing, and moving the graphic.
