Drive recorder and control method therefor
First Claim
1. A drive recorder comprising:
- a first memory;
a second memory;
an image collection unit that stores in real-time into said first memory image data representing images captured while a vehicle is in motion;
an acceleration collection unit that collects acceleration while the vehicle is in motion;
a sound collection unit that stores in real-time sound data representing sound while the vehicle is in motion;
an acceleration comparison unit that determines in real-time whether;
the acceleration collected by said acceleration collection unit exceeds a threshold value;
a sound recognition unit that determines if said sound data includes an accident sound which is a distinctive sound that is generated at an accident by performing sound recognition on said sound data when the acceleration exceeds said threshold value; and
a data transcribe unit that transcribes image data stored in said first memory into said second memory when said sound recognition unit determines that said accident sound is included in said sound data.

Abstract
A drive recorder 1 comprises a volatile memory 15, a nonvolatile memory 16, an image collection unit 111 that stores in real-time image data into the volatile memory 15, an acceleration collection unit 112, a sound collection unit 113 that stores in real-time sound data into the volatile memory 15, an acceleration comparison unit 114 that determines in real-time whether the acceleration exceeds a threshold value, a sound recognition unit 115 that determines if the sound data includes an accident sound which is a distinctive sound that is generated at an accident, by performing sound recognition on sound data when the acceleration exceeds the threshold value, and a data transcribe unit 116 that transcribes image data stored in the volatile memory 15 into the nonvolatile memory 16 when it is determined that the accident sound is included in the sound data.

16. A control method for a drive recorder having a first memory, a second memory, an image collection unit that stores in real-time into said first memory image data representing images captured while a vehicle is in motion, an acceleration collection unit that, collects acceleration while the vehicle is in motion, a sound collection unit that stores in real-time sound data representing sound while the vehicle is in motion, comprising the steps of:
-
determining in real-time whether the acceleration collected by said acceleration collection unit exceeds a threshold value;
determining if said sound data includes an accident sound which is a distinctive sound that is generated at an accident by performing sound recognition on said sound data collected by said sound collection unit when the acceleration exceeds the threshold value; and
transcribing said image data stored in said first memory into said second memory when said accident sound is determined to be included in said sound data.
