Abstract:
A method of compressing image data for transmission from a first device to a second device which is physically separate from but connected to the first device, the second device having a limited memory capacity, comprising the steps of:(a) querying said second device, thereby determining an available memory capacity of said second device;(b) encoding and storing said image data to obtain first encoded data;(c) comparing an amount of said first encoded data with said available memory capacity;(d) transmitting said first encoded data to said second device if the amount of said first encoded data does not exceed said available memory capacity;(e) compressing said image data with a certain compression ratio to obtain compressed data, if the amount of said first encoded data exceeds said available memory capacity;(f) encoding said compressed data to obtain second encoded data;(g) comparing the amount of said second encoded data with said available memory capacity;(h) transmitting said second encoded data to said second device if the amount of said second encoded data does not exceed said available memory capacity; and(i) repeating said steps (e), (f), (g), and (h), with successively increasing compression ratios in said step (e), if the amount of said second encoded data exceeds said available memory capacity, until the amount of second encoded data does not exceed said available memory capacity.
