The present invention relates to an apparatus and a method to store images when a valid impact event sound is inputted in addition to an acceleration sensor in a black box for vehicles. The apparatus comprises: a sensor part which outputs acceleration sensor values in accordance with an impact event; a mike part which receives an impact sound in accordance with the impact event; a camera part which photographs external images; and a processing part which stores images photographed through the camera part in a storage part for a certain time before and after the time point when the impact event started. According to the present invention, images of a certain time before and after the occurrence of impact event will be stored when impact sound in accordance with an impact event in addition to acceleration sensor values in a black box for vehicles and when the impact sound is matched to a valid sound by comparing the impact sound with a valid sound and an invalid sound and images will not be stored when matched with an invalid sound, thereby enabling the storage of a larger quantity of images in a memory with limited storage space.
