Abstract
An image capture apparatus determines a maximum power to be supplied from the image capture apparatus to an auxiliary device detachably attached to the image capture apparatus, based on information regarding a distance between a noise source included in the auxiliary device and an image sensor included in the image capture apparatus. The image capture apparatus then supplies power to the auxiliary device, without exceeding the determined maximum power and thereby effectively reduces the influence of noise caused by the auxiliary device, on the image sensor and a captured image.
Claims18
An image capture apparatus, comprising:
- one or more processors that, when executing a computer program stored in a memory, function as:
- a determination unit configured to determine a maximum power to be supplied from the image capture apparatus to an auxiliary device detachably attached to the image capture apparatus, based on information regarding a distance between a noise source included in the auxiliary device and an image sensor included in the image capture apparatus;
- and
- a control unit for controlling power supplied to the auxiliary device, without exceeding the maximum power determined by the determination unit,
- wherein the determination unit determines the maximum power so that the maximum power to be smaller in a case where a distance based on the information is a second distance than in a case where the distance is a first distance, and
- wherein the second distance is shorter than the first distance.
An auxiliary device of an image capture apparatus, the auxiliary device comprising:
- a memory that stores location information regarding a noise source included in the auxiliary device;
- and
- one or more processors that, when executing a program stored in a memory, function as:
- an output unit configured to output the location information to the image capture apparatus to which the auxiliary device is attached to the image capture apparatus.
An auxiliary device of an image capture apparatus, the auxiliary device comprising:
- a memory that stores information regarding a length of the auxiliary device;
- and
- one or more processors that, when executing a program stored in a memory, function as:
- an output unit configured to output the information regarding the length to the image capture apparatus to which the auxiliary device is attached to the image capture apparatus.
A control method of an image capture apparatus, comprising:
- determining a maximum power to be supplied from the image capture apparatus to an auxiliary device detachably attached to the image capture apparatus, based on information regarding a distance between a noise source included in the auxiliary device and an image sensor included in the image capture apparatus;
- and
- supplying power to the auxiliary device, without exceeding the maximum power determined in the determining,
- wherein the determining determines the maximum power so that the maximum power to be smaller in a case where a distance based on the information is a second distance than in a case where the distance is a first distance, and
- wherein the second distance is shorter than the first distance.
A control method of an auxiliary device of an image capture apparatus, wherein the auxiliary device includes a memory that stores location information regarding a noise source included in the auxiliary device, the control method comprising,
- outputting the location information to the image capture apparatus to which the auxiliary device is attached to the image capture apparatus.
A non-transitory computer-readable medium storing a program causing, when executed, a computer to function as an image capture apparatus, comprising:
- a determination unit configured to determine a maximum power to be supplied from the image capture apparatus to an auxiliary device detachably attached to the image capture apparatus, based on information regarding a distance between a noise source included in the auxiliary device and an image sensor included in the image capture apparatus;
- and
- a control unit for controlling power supplied to the auxiliary device, without exceeding the maximum power determined by the determination unit,
- wherein the determination unit determines the maximum power so that the maximum power to be smaller in a case where a distance based on the information is a second distance than in a case where the distance is a first distance, and
- wherein the second distance is shorter than the first distance.
