Abstract
An image processing apparatus includes an area setter configured to set a target area in a first image among a plurality of captured images acquired by imaging at different time from each other, an area detector configured to detect a corresponding area relevant to the target area in a plurality of second images among the plurality of captured images, a focus state acquirer configured to acquire focus states of the target area and the corresponding area, and a classification processor configured to perform classification processing that classifies the plurality of captured images into a plurality of groups according to the focus states.
Claims11
An image processing apparatus comprising:
- at least one processor;
- and
- at least one memory coupled to the at least one processor storing instructions that, when executed by the at least one processor, causes the at least one processor to function as:
- (1) an area setter configured to set a target area to confirm a focus state in a first image of a plurality of images captured by imaging at mutually different times, wherein the target area is a user-specified target area specified by a user via a user interface;
- (2) an acquirer configured to acquire, from each of the plurality of images, information on a first scale and a second scale, wherein the first scale represents imaging time and the second scale represents a focus state;
- (3) an evaluation updater configured to update an evaluation regarding at least one of the first scale and the second scale, wherein the evaluation updater modifies a threshold used to classify the focus state of the images and dynamically applies the modified threshold to reclassify the images;
- (4) an image group setter configured to (a) detect, from second images of the plurality of images, an image including a corresponding area having relevance to the target area and (b) set the detected image and the first image as an image group on the first scale;
- (5) a classification processor configured to perform classification processing that classifies the image group into a plurality of groups using the second scale;
- and
- (6) a display processor configured to control a display unit to display information on the image,
- wherein the classification processor updates the plurality of groups as the evaluation updater updates the evaluation.
An image processing method comprising the steps of:
- setting a target area to confirm a focus state in a first image of a plurality of images captured by imaging at mutually different times, wherein the target area is a user-specified target area specified by a user via a user interface;
- acquiring, from each of the plurality of images, information on a first scale and a second scale, wherein the first scale represents imaging time and the second scale represents a focus state;
- updating an evaluation regarding at least one of the first scale and the second scale, wherein the updating modifies a threshold used to classify the focus state of the images and dynamically applies the modified threshold to reclassify the images;
- detecting, from second images of the plurality of images, an image including a corresponding area having relevance to the target area;
- setting the detected image and the first image as an image group on the first scale;
- performing classification processing that classifies the image group into a plurality of groups using the second scale;
- and
- controlling a display unit to display information on the image,
- wherein the plurality of groups is updated as the evaluation is updated.
