Abstract

A drive recorder has: a camera; an image recording section that records an image captured by the camera; a sensor that is installed with its relative posture with respect to the camera being fixed, detects an acceleration, and outputs an acceleration signal; and an image correcting section that corrects a top-and-bottom direction or an inclination of an image that is recorded in the image recording section.

Claims

1. A recorded image correction method for a drive recorder, comprising:

generating an acceleration signal from a sensor that detects an acceleration; and

correcting a top-and-bottom direction or an inclination of a captured image that is output from a camera and recorded in a drive recorder based on the acceleration signal.

2. A drive recorder comprising:

a camera;

an image recording section that records an image captured by the camera;

a sensor that is installed with its relative posture with respect to the camera being fixed, detects an acceleration, and outputs an acceleration signal; and

an image correcting section that corrects a top-and-bottom direction or an inclination of an image that is recorded in the image recording section based on the acceleration signal.

3. The drive recorder according to claim 2, further comprising an image display section that displays the image output from the camera or the image recorded in the image recording section.

4. A drive recorder system comprising:

a camera;

an image recording section that is different from the camera, receives an image captured by the camera with or without a wire, and records the image;

a sensor that is installed with its relative posture with respect to the camera being fixed, detects an acceleration, and outputs an acceleration signal; and

an image correcting section that corrects a top-and-bottom direction or an inclination of an image that is recorded in the image recording section based on the acceleration signal.

5. The drive recorder system according to claim 4, further comprising an image display section that displays the image output from the camera or the image recorded in the image recording section.
