Image display apparatus and image display method

摘要

An image display apparatus is provided that can obtain a stable and easy to view detection frame and cut-out image in a captured image in which there is a possibility that a congested region and a non-congested region are mixed, such as an omnidirectional image. Congested region detecting section detects a congested region in a captured image by detecting a movement region of the captured image. Object detecting section detects images of targets in the captured image by performing pattern matching. Detection frame forming section forms a congested region frame that surrounds a congested region detected by congested region detecting section, and object detection frame that surround image of target detected by object detecting section.

主权项

1. An image display apparatus, comprising:
a processor; a memory; a congested region detector that detects a congested region in a captured image by detecting a movement region of the captured image, wherein the movement region of the captured image is detected by determining when a difference value indicating an inter-frame difference with respect to the captured image is equal to or greater than a threshold value; an object detector that detects an image of a target in the captured image by performing pattern matching; and a detection frame former that forms a congested region frame that surrounds the congested region and indicates an area occupied with the congested region in the captured image, and an object detection frame that surrounds the image of the target and indicates an area occupied with the target in the captured image, a display that displays the captured image, by overlapping the congested region frame and the target detection frame over the captured image, wherein, when the detected congested frame and the detected image of the target overlap, the detection frame former forms the congested region frame without forming the object detection frame for the detected image of the target overlapping the congested region, and wherein, when the target is moving in the direction of the congested region, the congested region frame is gradually enlarged in size to include the target.
