IN-VEHICLE DEVICE FOR RECORDING MOVING IMAGE DATA
First Claim
1. An in-vehicle moving image data recording apparatus mounted in a vehicle, comprising:
- a normal image quality coding unit for compressing moving image data generated from images of surroundings of the vehicle captured by a camera unit mounted in the vehicle with a normal image quality to generate a normal-quality compressed moving image data;
a high image quality coding unit for compressing the moving image data with an image quality higher than the normal image quality to generate a high-quality compressed moving image data;
a normal image quality data storage unit for recording therein the normal-quality compressed moving image data;
a trigger detecting unit for detecting an abnormal condition which possibly happens to the vehicle currently travelling; and
a high image quality data storage unit for recording therein the high-quality compressed moving image data based on a timing by which the abnormal condition is detected by the trigger detecting unit.

Abstract
A normal image quality coding unit generates normal-quality compressed moving image data by compressing moving image data generated by capturing an image around a vehicle with a normal image quality. A high image quality coding unit generates high-quality compressed moving image data by compressing the moving image data with an image quality higher than the normal image quality. The normal-quality compressed moving image data is recorded in a normal image quality data storage unit. A trigger detection unit detects an abnormal condition which possibly happens to the vehicle currently travelling. A high image quality data storage unit records therein the high-quality compressed moving image data based on a timing by which the abnormal condition is detected by the trigger detection unit.
