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.

摘要： Disclosed is an olefin polymer of having a number average molecular weight of 500 to 50,000 and having an acid anhydride group only at a terminal thereof, and a resin composition containing the olefin polymer. When the olefin polymer having an acid anhydride group only at a terminal thereof is blended with a polyamide, a resin composition having extremely improved toughness, particularly in tensile elongation as compared to the polyamide alone can be obtained. Further, when a ternary composition is prepared by blending the olefin polymer of the present invention as component (A), a polyamide as component (B) and an olefin-containing polymer other than the olefin polymer [component (A)] as component (C), component (A) acts as a compatibility agent between component (B) and a component (C), so that the efficiency of dispersion of component (C) in component (B), or of component (B) in component (C), is improved, and a resin composition having markedly improved toughness (tensile elongation and impact resistance), LLC resistance and low water absorption properties can be obtained.
