IN-VEHICLE RECORDER, PROGRAM, AND DATA RECORDING METHOD OF THE IN-VEHICLE RECORDER

摘要

An in-vehicle recorder or the like capable of keeping a reliable record as to whether alcohol is taken to effectively inhibit drive under the influence of the alcohol. The in-vehicle recorder (1) is characterized by that it includes a front camera (11) for imaging a visual image forward of a vehicle, an impact determination part (22) for detecting an accident from an impact level detected by an acceleration sensor (12), an alcohol sensor (14) for measuring an alcohol concentration in a vehicle interior, an image data creation part (24) for creating image data including the measurement data of the alcohol sensor (14) embedded in the imaged data of the front camera (11), a tamper-proof processing part (25) for tamper-proof processing on the image data, and a recording part (26) for recording the tamper-proof-processed image data in a storage memory (M).
