Claim:
1. A method of determining a bit rate corresponding to a first significance level by an imaging device which stores image information using a bit rate varied according to a significance level, the method comprising: allocating a memory space for storing obtained image information; determining a bit rate corresponding to the first significance level, the bit rate satisfying a distortion requirement according to the first significance level and making energy consumption minimized when image information having the first significance level is stored; determining whether to exceed the allocated memory space, when image information is processed according to the determined bit rate; and if the allocated memory space is determined as exceeding a size of the processed image information, calculating a bit rate of to a second significance level, which makes a change in energy consumption minimized when the bit rate is lowered, to lower the bit rate of the second significance level.
