DISTANCE MEASUREMENT CAMERA SYSTEM
Document Type and Number:
Japanese Patent JP2021092420
Kind Code:
A
Abstract:
To provide a distance measurement camera system in which images to be displayed on a monitor and the like can be considered for privacy, but the image is an image easy to determine an attitude of a person.SOLUTION: A distance measurement camera system comprises: an image sensor 5 that has sensitivity in a wavelength region of a near infrared in addition to visible light; a camera that is provided with an ISP 6 processing image information captured by the image sensor; a camera device that is provided with a near infrared laser 12 irradiating an imaging region of the camera with near infrared light; and a monitor that displays an output image of the camera. The image sensor is configured to acquire time lag information on light until the irradiation light of the near infrared laser gets to the image sensor from the light thereof is reflected upon an object, and the ISP is configured to, on the basis of the time lag information until the image sensor acquires the time lag information since the near infrared of the near infrared laser is irradiated, calculate a distance for each pixel, and output color or brightness information in accordance with the distance. On a monitor, the image is displayed that varies the brightness according to the distance.SELECTED DRAWING: Figure 3
