Abstract: Apparatus and method for processing wide dynamic range (WDR) image are disclosed. The WDR image processing apparatus could be integrated within an image sensor or an image backend apparatus. Whether the m-th bit of the sensing image signal is equal to 1 is determined. If the m-th bit is equal to 1, then the values corresponding to the m-th to the (m?r)-th bits are added by first offset to output a WDR image signal. If the m-th bit is not equal to 1, then whether the (m?1)-th bit is equal to 1 is determined. If the (m?1)-th bit is equal to 1, then the values corresponding to the (m?1)-th to the (m?s)-th bits are added by a second offset to output the WDR image signal. The same processing is applied up to the (m?t)-th bit, m, n, r, s and t are positive integers, and m is greater than n.
