  • Method and system for detecting digital camera failure
    Patent number: 6671389
    Abstract: A system for detecting a digital camera failure captures an image with the digital camera. The system compresses the image into a compressed image file and compares the size of the compressed image file with a predetermined file size. A digital camera failure is indicated if the size of the compressed image file is greater than a predetermined upper limit file size or less than a predetermined lower file size limit. The system may also compare the number of pixels of a predetermined color with the total number of pixels of the captured image. A digital camera failure is indicated if the number of pixels of the predetermined color is greater than a predetermined percentage of the total number of pixels of the captured image.
