Control apparatus for outputting registration information for object authentication to an external device, image pickup apparatus, and control method

1 . A control apparatus comprising:

a memory storing instructions, and first feature information about a feature of a first object acquired from a first object area image of a first captured image and the first object area image as registration information for object authentication; and

a processor configured to execute the instructions to:

detect an object from a captured image,

acquire feature information about a feature of the object from an object area image that includes the object in the captured image, and

output the first object area image without the first feature information from the registration information to an external device,

wherein the processor is configured to authenticate that a second object is the first object using the first feature information and second feature information about a feature of the second object acquired from a second object area image in a second captured image.

2 . The control apparatus according to claim 1 , wherein the processor is configured to perform at least one of focus control and exposure control for the second object that has been authenticated as the first object.

3 . The control apparatus according to claim 1 , wherein in a case where the memory stores the registration information for each of a plurality of first objects, the processor is configured to output a single file to the external device by including the first object area image of each of the plurality of first objects in the single file.

4 . A control apparatus comprising:

a memory storing instructions, and first feature information about a feature of a first object acquired from a first object area image of a first captured image and the first object area image as registration information for object authentication; and

a processor configured to execute the instructions to:

detect an object from a captured image,

acquire feature information about a feature of the object from an object area image that includes the object in the captured image, and

output the first object area image without the first feature information from the registration information to an external device,

wherein in a case where the memory stores the registration information for each of a plurality of first objects and the registration information includes information about an order of priority among the plurality of first objects, the processor is configured to output information about the first object area image of each of the plurality of first object and the order of priority to the external device.

5 . The control apparatus according to claim 4 , wherein in a case where a plurality of second objects are detected from the second captured image, the processor is configured to preferentially perform at least one of focus control and exposure control for one of the plurality of second objects that has been authenticated as the first object and has a higher order of priority.

6 . An image pickup apparatus comprising:

the control apparatus of claim 1 ; and

an image sensor.

7 . A control method comprising the steps of:

detecting an object from a captured image;

acquiring feature information about a feature of the object from an object area image that includes the object in the captured image;

storing first feature information about a feature of a first object acquired from a first object area image of a first captured image and the first object area image as registration information for object authentication;

authenticating that a second object is the first object using the first feature information and second feature information about a feature of the second object acquired from a second object area image in a second captured image; and

outputting the first object area image without the first feature information from the registration information to an external apparatus.

8 . A non-transitory computer-readable storage medium storing a program that causes a computer to execute the control method according to claim 7 .

9 . The control apparatus according to claim 4 , wherein the processor is configured to authenticate that a second object is the first object using the first feature information and second feature information about a feature of the second object acquired from a second object area image in a second captured image.

10 . The control apparatus according to claim 9 , wherein the processor is configured to perform at least one of focus control and exposure control for the second object that has been authenticated as the first object.

11 . A control method comprising the steps of:

detecting an object from a captured image;

acquiring feature information about a feature of the object from an object area image that includes the object in the captured image;

storing first feature information about a feature of a first object acquired from a first object area image of a first captured image and the first object area image as registration information for object authentication, the registration information further including information indicating an order of priority among the plurality of first objects; and

outputting the first object area image without the first feature information from the registration information to an external apparatus.

12 . A non-transitory computer-readable storage medium storing a program that causes a computer to execute the control method according to claim 11 .
