[edit] File Information

QV Series cameras would capture images in a proprietary .CAM format. The CAM format appears to have different encodings, one being a JPEG format.

[edit] File Identification

CAM files have the header hex values "07204D4D"[5][6]. Some files have JFIF encoding while others have something else. More research needed.

JPEG encoded images can simply be extracted by deleting the first 54 bytes of the file and saving with .JPG extension.
