Abstract

An image processing apparatus includes an input unit that inputs an image, a detection unit that detects an object from the image input by the input unit, and an image determination unit that determines, based on a result of detection of the object performed by the detection unit on the image input by the input unit a reference image that is to be displayed on a display screen allowing a user to specify an image processing region.

First claim

What is claimed is:

1 . An image processing apparatus comprising:
an input unit configured to input an image; a detection unit configured to detect an object from the image input by the input unit; and an image determination unit configured to determine, based on a result of detection of the object performed by the detection unit on the image input by the input unit, a reference image that is to be displayed on a display screen allowing a user to specify an image processing region.

2 . The image processing apparatus according to claim 1 , wherein the image determination unit determines, as the reference image, an image in which a number of objects detected by the detection unit from among a plurality of images input by the input unit satisfies a predetermined condition.

3 . The image processing apparatus according to claim 1 , further comprising a generation unit configured to generate a superimposed image by superimposing an object image corresponding to an object detected from one or more images including a first image from among a plurality of images input by the input unit on a second image different from the one or more images,
wherein the image determination unit determines the superimposed image as the reference image.

4 . The image processing apparatus according to claim 3 , wherein the generation unit generates the superimposed image by setting an object detected from the one or more images including the first image as the object image and superimposing the object image on the second image.

5 . The image processing apparatus according to claim 3 , wherein the generation unit generates the superimposed image by superimposing, on a position in the second image corresponding to a position of an object detected from the one or more images including the first image, an object image that represents the detected object.

6 . The image processing apparatus according to claim 3 , wherein the generation unit generates the superimposed image by superimposing, on the second image, an object image corresponding to an object that falls within a predetermined size range among objects detected from the one or more images.

7 . The image processing apparatus according to claim 1 , further comprising an imaging unit,
wherein the input unit inputs an image obtained by image capturing performed by the imaging unit.

8 . The image processing apparatus according to claim 1 , further comprising an editing unit configured to perform editing processing on the object detected by the detection unit from the image,
wherein the image processed by the editing unit is displayed as the reference image on the display screen.

9 . The image processing apparatus according to claim 1 , further comprising:
a reception unit configured to receive a user input specifying coordinates in the reference image displayed on the display screen; and a region determination unit configured to determine the image processing region according to the user input received by the reception unit.

10 . The image processing apparatus according to claim 1 , further comprising:
a reception unit configured to receive a user input specifying an object that is to be targeted for image processing to be performed in the image processing region from among objects in the reference image displayed on the display screen; and a region determination unit configured to determine the image processing region according to the user input received by the reception unit.

11 . The image processing apparatus according to claim 1 , further comprising:
a reception unit configured to receive a user input specifying an object that is to be targeted for image processing to be performed in the image processing region and an object that is not to be targeted for the image processing from among objects in the reference image displayed on the display screen; and a region determination unit configured to determine the image processing region according to the user input received by the reception unit.

12 . The image processing apparatus according to claim 1 , further comprising a change unit configured to change a position of the object in the reference image according to an input condition of a user input specifying the image processing region after the reference image is displayed on the display screen.

13 . The image processing apparatus according to claim 1 , further comprising a control unit configured to perform, in a case where a nondetection region in which a number of times the detection unit has detected objects in a predetermined number of images is less than a threshold value is included in an image processing region specified by a user operation, at least one of canceling the specified image processing region and outputting a notification indicating the nondetection region.

14 . The image processing apparatus according to claim 1 , wherein image processing to be performed in the image processing region includes at least one of congestion detection for detecting that objects a number of which is greater than or equal to a threshold value corresponding to an area of the image processing region are present, congestion degree detection for detecting a congestion degree corresponding to a ratio of a number of objects to an area of the image processing region, dwell detection for detecting that a same object continues being present within the image processing region for a time greater than or equal to a predetermined time threshold, dwell degree detection for detection a dwell degree corresponding to a time for which the same object continues being present within the image processing region, passage detection for detecting that an object has passed over a detection line, removed object detection for detecting that an object has carried away a predetermined object, and abandoned object detection for detecting that an object has deserted a predetermined object.

15 . An image processing method comprising:
inputting an image; detecting an object from the input image; and determining, based on a result of detection of the object performed on the input image, a reference image that is to be displayed on a display screen allowing a user to specify an image processing region.

16 . The image processing method according to claim 15 , further comprising determining, as the reference image, an image in which a number of objects detected from among a plurality of input images satisfies a predetermined condition.

17 . The image processing method according to claim 15 , further comprising:
generating a superimposed image by superimposing an object image corresponding to an object detected from one or more images including a first image from among a plurality of input images on a second image input later than the one or more images; and determining the superimposed image as the reference image.

18 . A non-transitory computer-readable storage medium storing computer executable instructions that, when executed by a computer, cause the computer to perform a method comprising:
inputting an image; detecting an object from the input image; and determining, based on a result of detection of the object performed on the input image, a reference image that is to be displayed on a display screen to allow a user to specify an image processing region.

19 . The non-transitory computer-readable storage medium according to claim 18 , wherein the method further comprises determining, as the reference image, an image in which a number of objects detected from among a plurality of input images
