1. A method of digital image transmission, comprising:
receiving a plurality of first pixel values associated with a first image in a sequence of images;
determining a first change importance factor (CIF) based on a degree of variation among the plurality of first pixel values, a degree of change between the plurality of first pixel values and a plurality of second pixel values associated with a second image that precedes the first image in the sequence of images, and a degree of variation among the plurality of second pixel values;
selectively updating a count value based at least in part on whether the plurality of second pixel values is transmitted to a receiving device;
adjusting the first CIF based on the count value; and
selectively transmitting the plurality of first pixel values to the receiving device based at least in part on the adjusted first CIF.
