Abstract

This recording mode changing device is provided with: a means for determining, according to the lighting status of the lamps of a prescribed traffic signal, whether or not it is necessary to change the data recording mode of a prescribed camera; and a means for changing the data recording mode of the prescribed camera in accordance with the determination result.

First claim

What is claimed is:

1 . A recording mode changing device comprising:
a memory storing instruction; and one or more processors configured to execute the instructions to: determine whether it is necessary to change a data recording mode of a predetermined camera according to a lighting state of a lamp of a predetermined traffic signal; and change a data recording mode of the predetermined camera according to the determination.

2 . The recording mode changing device according to claim 1 , wherein
the one or more processors are further configured to execute the instructions to: change the data recording mode by using stage information indicating a lighting state of a lamp of the traffic signal.

3 . The recording mode changing device according to claim 1 , wherein
the one or more processors are further configured to execute the instructions to: change the data recording mode at a predetermined timing, the predetermined timing based on a change in a lighting state of a lamp of the traffic signal.

4 . The recording mode changing device according to claim 1 , wherein
the camera is positioned to be able to capture a lamp of the traffic signal, and wherein the one or more processors are further configured to execute the instructions to identify a lighting state of a lamp of the traffic signal from an image captured by the camera.

5 . The recording mode changing device according to claim 1 , wherein the change in the data recording mode includes a change in at least one of resolution and a frame rate.

6 . The recording mode changing device according to claim 1 , wherein the change in the data recording mode includes switching between recording by a moving image and recording by a still image.

7 . The recording mode changing device according to claim 1 , wherein
the predetermined camera is a camera installed to capture an intersection, and wherein the one or more processors are further configured to execute the instructions to: change a data recording mode of the camera according to a lighting state of a lamp of a traffic signal at the intersection.

8 . (canceled)

9 . A recording mode changing method that causes a computer to execute:
determining whether it is necessary to change a data recording mode of a predetermined camera according to a lighting state of a lamp of a predetermined traffic signal; and changing a data recording mode of the predetermined camera according to the determination.

10 . A program recording medium storing a program for causing a computer to execute:
determining whether it is necessary to change a data recording mode of a predetermined camera according to a lighting state of a lamp of a predetermined traffic signal; and changing a data recording mode of the predetermined camera according to the determination.
