Damaged tires cause many fatal car accidents that claim lives worldwide. The use of a regular digital camera that can generate JPEG images, so as to become aware of damaged tires, is proposed. The digital camera repeatedly takes pictures of the car’s tires. When there is a drastic change in a particular block of JPEG, the value of many of its frequency coefficients will be high and it will be compressed into many more bits; therefore, if the image is overly large, an embedded computer system will turn on a noticeable light-emitting diode in the car. The driver will be aware of the damaged tire before a severe accident would possibly happen.
