Abstract

An imaging control apparatus includes a detection unit configured to detect, from a captured image, subjects belonging to a plurality of types including a first type and a second type a switching unit configured to switch a type, a selection unit configured to select any subject from among a plurality of subjects belonging to the second type, and a control unit configured to perform control so as to display a first subject belonging to the first type in a first display manner and display a second subject belonging to the second type in a second display manner in a case where the type for which the predetermined processing is the first type, and display the second subject in the first display manner in response to switching to the second type by the switching unit.

First claim

What is claimed is:

1 . An imaging control apparatus comprising:
a detection unit configured to detect, from a captured image, subjects belonging to a plurality of types including a first type and a second type; a switching unit configured to switch a type for which predetermined processing is to be performed from any of the first type and the second type; a selection unit configured to select any subject from among a plurality of subjects belonging to the second type in the captured image and among the detected subjects; and a control unit configured to perform control so as to display a first subject belonging to the first type in a first display manner and display a second subject belonging to the second type in a second display manner in a case where the type for which the predetermined processing is to be performed is switched to the first type by the switching unit, and display the second subject in the first display manner in response to switching of the type for which the predetermined processing is to be performed from the first type to the second type by the switching unit.

2 . The imaging control apparatus according to claim 1 , wherein the control unit sets the second subject selected by the selection unit as a target for the predetermined processing in response to the switching of the type for which the predetermined processing is to be performed from the first type to the second type by the switching unit.

3 . The imaging control apparatus according to claim 1 , further comprising a storage unit configured to store master data with which feature data for each of the types is registered, wherein the detection unit detects the subjects belonging to the first type and the second type using the master data corresponding to the first type and the master data corresponding to the second type.

4 . The imaging control apparatus according to claim 1 , wherein, in a case where the type for which the predetermined processing is to be performed is switched to the first type by the switching unit, in response to a first operation for selecting any subject from a plurality of subjects belonging to the first type in the captured image among the detected subjects, the control unit displays the selected subject in the first display manner and also sets the first subject displayed in the first display manner as a target for the predetermined processing.

5 . The imaging control apparatus according to claim 1 , wherein, in a case where the type for which the predetermined processing is to be performed is switched to the first type by the switching unit, in response to a second operation for selecting any subject from the plurality of subjects belonging to the second type in the captured image among the detected subjects, the control unit displays the selected subject in the second display manner, and the control unit sets the second subject displayed in the second display manner as a target for the predetermined processing in response to the switching of the type for which the predetermined processing is to be performed from the first type to the second type by the switching unit.

6 . The imaging control apparatus according to claim 1 , wherein the first operation for selecting any subject from among the plurality of subjects belonging to the first type in the captured image among the detected subjects and the second operation for selecting any subject from among the plurality of subjects belonging to the second type in the captured image among the detected subjects are set, and the first operation and the second operation are performed by operations on different predetermined operation members.

7 . The imaging control apparatus according to claim 1 , wherein the types include at least any one of a human, an animal, a human pupil, an animal pupil, and a vehicle.

8 . The imaging control apparatus according to claim 1 , further comprising a type selection unit configured to select, as the types, types of subjects to be set as the first type and the second type.

9 . The imaging control apparatus according to claim 8 , wherein, in a case where the type for which the predetermined processing is to be performed is switched to the first type by the switching unit, in response to the selection of the type to be set as the first type by the type selection unit, the control unit displays the subject belonging to the selected type in the first display manner.

10 . The imaging control apparatus according to claim 8 , wherein, in a case where the type for which the predetermined processing is to be performed is switched to the second type by the switching unit, in response to the selection of the type to be set as the second type by the type selection unit, the control unit displays the subject belonging to the selected type in the second display manner.

11 . The imaging control apparatus according to claim 8 , wherein the type selection unit selects, from among predetermined combinations of the first type and the second type, one of the combinations.

12 . The imaging control apparatus according to claim 1 , wherein the predetermined processing includes at least any one of automatic focus processing, automatic exposure processing, and tracking processing.

13 . A method for controlling an imaging control apparatus, the method comprising:
detecting, from a captured image, subjects belonging to a plurality of types including a first type and a second type; switching a type for which predetermined processing is to be performed from any of the first type and the second type; selecting any subject from a plurality of subjects belonging to the second type in the captured image and among the detected subjects; and performing control so as to display a first subject belonging to the first type in a first display manner and display a second subject belonging to the second type in a second display manner in a case where the type for which the predetermined processing is to be performed is switched to the first type by the switching, and display the second subject in the first display manner in response to switching of the type for which the predetermined processing is to be performed from the first type to the second type by the switching.

14 . A non-transitory computer-readable storage medium storing a program for causing a computer to execute the control method, the method comprising:
detecting from a captured image, subjects belonging to a plurality of types including a first type and a second type from a captured image; switching a type for which predetermined processing is to be performed from any of the first type and the second type; selecting any subject from a plurality of subjects belonging to the second type in the captured image and among the detected subjects; and performing control so as to display a first subject belonging to the first type in a first display manner and display a second subject belonging to the second type in a second display manner in a case where the type for which the predetermined processing is to be performed is switched to the first type by the switching, and display the second subject in the first display manner in response to switching of the type for which the predetermined processing is to be performed from the first type to the second type by the switching.
