Patent Images

1. An image capture device comprising:

  • an optical system;

    an image sensor on a substrate for capturing imagery provided by the optical system, in which captured imagery includes encoded information, and in which the captured imagery comprises first color information, second color information and third color information;

    a compression module for compressing the captured imagery captured by said image sensor, in which the compression module transforms the captured imagery into compressed captured imagery;

    one or more processors configured for;

    detecting the encoded information from the compressed captured imagery, in which said detecting utilizes different color information weightings so that at least the first color information and the third color information are weighted differently than one another for detection of the encoded information; and

    once detected, providing the encoded information for output or display.
