According to an embodiment of the present invention, an apparatus for controlling the noise level of a wide dynamic range (WDR) image includes a first WDR image generating block processing a long exposure image signal having a relatively long exposure time using a first weighted value, generating a first image signal according to a processing result, processing a short exposure image signal having a relatively short exposure time using a second weighted value, generating a second image signal according to a processing result, and synthesizing the first image signal with the second image signal to generate a first WDR image signal, a control signal generating unit calculating a difference between the second weighted value and a reference weighted value, and generating control signals according to a calculation result, and a second WDR image generating block adjusting the noise level of the first WDR image signal using the control signals, and generating a second WDR image signal. |
