Title:
IMAGE PROCESSING APPARATUS, MONITORING SYSTEM, AND IMAGE PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2021097416
Kind Code:
A
Abstract:
To visually present to a user that, in what kind of place in an imaging area of a camera device, an unmanned flying body is detected and what kind of sound source exists in what other places in the same imaging area, without deteriorating visibility of the captured image of the camera device.SOLUTION: A sound source direction detection unit 34, on the basis of sound collected by a microphone array MAk, derives sound pressure that specifies magnitude of sound in an imaging area for each predetermined unit of pixels constituting a captured image in the imaging area. An output control section 35, in accordance with comparison between the sound pressure and a plurality of threshold values relating to the magnitude of sound, superimposes sound source visual information obtained by gradually converting the sound pressure into different visual images for each predetermined unit of the pixels constituting the captured image in the imaging area and displays them in a first monitor MN1. The sound source direction detection section 34, when any one of the sound source positions in the captured image in the imaging area is specified, derives the sound pressure for each value obtained by dividing a predetermined unit of pixels constituting a rectangular range including the sound source position by size ratio between the rectangular range and the captured image in the imaging area.SELECTED DRAWING: Figure 16
