A drive recorder and a drive recorder system that can check the content of the image captured by an image capturing unit that outputs a video signal at a frequency not affected by LED traffic light flashing. The drive recorder includes an image converting unit for converting a received video signal into image information, and for outputting the image information in the form of a video signal, a storage unit for storing the converted image information, and a control unit for performing control so that the video signal is converted into the image information by using a first frequency not affected by LED traffic light flashing, and so that the image information stored in the storage unit is output in the form of a video signal by using a second frequency corresponding to a standard video signal.

A drive recorder for recording video information received from an image capturing unit on a recording medium includes an acceleration sensor which outputs acceleration information representing an acceleration applied to a vehicle, and a control unit which, determines that a recording condition holds and records video information captured for a first predetermined period of time before the occurrence of the recording condition and video information captured for a second predetermined period of time after the occurrence of the recording condition on the recording medium when the acceleration information equals or exceeds a threshold, wherein after the recording condition holds, the control unit does not record newly captured video information on the recording medium when the acceleration information again becomes equal to or exceeds the threshold in less than a third predetermined period of time which is shorter than the second predetermined period of time.

Drive recorder

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.
