In-vehicle device for recording moving image data

摘要

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.

主权项

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 constantly generated from images of surroundings of the vehicle captured by a camera unit mounted in the vehicle with a normal image quality to constantly 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 constantly 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 constantly recording therein the high-quality compressed moving image data outputted by the high image quality coding unit and storing the high-quality moving image data based on a trigger detection timing by the trigger detecting unit, wherein the normal-quality compressed moving image data is recorded when the high-quality compressed moving image data is recorded.
