Abstract:
An object of the invention is to provide a drive recorder that can detect acceleration so that the acceleration exerted on a vehicle traveling around a curve will not be erroneously detected as excessive acceleration, as long as the steering wheel is operated in a usual manner. More particularly, the invention provides a drive recorder that includes an acceleration sensor for detecting a first acceleration along a traveling direction of a vehicle and a second acceleration along a transverse direction of the vehicle, and a control unit which obtains a combined acceleration based on the first acceleration and on a value obtained by subtracting a correction value from the absolute value of the second acceleration, and when the combined acceleration exceeds a threshold value, records video information received from an image capturing unit onto a recording device.
