Image processing apparatus, control method thereof, image capturing apparatus, and storage medium

1 . An image processing apparatus configured to process a captured image, the image processing apparatus comprising:

at least one processor and memory storing instructions that, when executed, configure the at least one processor to function as:

a detection unit configured to detect a train from the captured image and to acquire first and second detection areas in the captured image, wherein the second detection area is within the first detected area and covers a front portion of the detected train included as part of the first detection area;

a relevant area setting unit configured to set the first detection area as a relevant area relevant to the second detection area;

a search area setting unit configured to set a search area related to the object in the image using a position of a fixed frame that is displayable on a display of an image capture apparatus that captured the image; and

a target setting unit configured to set a target area in the image for processing, the target area being set by:

determining whether either the search area and the second detection area overlap or the search area and the relevant area overlap; and

when it is determined that either the search area and the second detection area overlap or the search area and the relevant area overlap, setting the second detection area as the target area, and

when it is determined that the search area does not overlap the second detection area and the search area does not overlap the relevant area, setting the search area as the target area.

2 . The image processing apparatus according to claim 1 ,

wherein the relevant area setting unit sets an area not including the second detection area as the relevant area, and

wherein the target setting unit issues a notification of the set target area.

3 . The image processing apparatus according to claim 1 ,

wherein the first detection area is an area corresponding to a first part of an object, and

wherein the second detection area is an area corresponding to a second part of the object.

4 . The image processing apparatus according to claim 1 ,

wherein the detection unit detects first and second objects,

wherein the first detection area is an area corresponding to the first object, and

wherein the second detection area is an area corresponding to the second object.

5 . The image processing apparatus according to claim 2 , wherein, in a case where a notification of the set target area is issued, the target setting unit does not issue a notification of the relevant area.

6 . The image processing apparatus according to claim 1 , further comprising a display to display a first frame corresponding to the search area and a second frame corresponding to the target area.

7 . An image capturing apparatus comprising:

the image processing apparatus according to claim 1 ;

an image capturing unit configured to capture an image of an object via an imaging optical system; and

a display unit configured to display a captured image.

8 . The image capturing apparatus according to claim 7 , wherein the target setting unit issues a notification of the determined target area as a target area for focus adjustment control of the imaging optical system using the display unit.

9 . The image capturing apparatus according to claim 8 , further comprising a specifying unit configured to specify an object in an image,

wherein the target setting unit performs processing for determining whether a position in the image specified by the specifying unit is within the target area or the relevant area and determining the target area.

10 . A control method to be executed by an image processing apparatus configured to process a captured image, the control method comprising:

detecting a train from the captured image and acquiring first and second detection areas in the captured image, wherein the second detection area is within the first detected area and covers a front portion of the detected train including as part of the first detection area;

setting the first detection area as a relevant area relevant to the second detection area;

setting a search area related to the object in the image using a position of a fixed frame that is displayable on a display of an image capture apparatus that captured the image; and

setting a target area in the image for processing, the target area being set by:

determining whether either the search area and the second detection area overlap or the search area and the relevant area overlap; and

when it is determined that either the search area and the second detection area overlap or the search area and the relevant area overlap, setting the second detection area as the target area, and

when it is determined that the search area does not overlap the second detection area and the search area does not overlap the relevant area, setting the search area as the target area.

11 . A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor, configures an image processing apparatus to execute a control method, the control method comprising:

detecting a train from the captured image and acquiring first and second detection areas in the captured image, wherein the second detection area is within the first detected area and covers a front portion of the detected train including as part of the first detection area;

setting the first detection area as a relevant area relevant to the second detection area;

setting a search area related to the object in the image using a position of a fixed frame that is displayable on a display of an image capture apparatus that captured the image; and

setting a target area in the image for processing, the target area being set by:

determining whether either the search area and the second detection area overlap or the search area and the relevant area overlap; and

when it is determined that either the search area and the second detection area overlap or the search area and the relevant area overlap, setting the second detection area as the target area, and

when it is determined that the search area does not overlap the second detection area and the search area does not overlap the relevant area, setting the search area as the target area.
