A method for removing haziness in a digital image is provided. The method includes receiving an input digital image having some haze content from an image capturing device. The input digital image is downscaled to obtain a low-resolution image. Further, a minimum intensity dark channel is determined for each local patch of the low-resolution image to obtain a dark channel image corresponding to the low-resolution image. Furthermore, a transmission map of the low-resolution image is determined based on the dark channel image. Moreover, an atmospheric light value associated with the low-resolution image is also determined. The method further includes applying the determined transmission map and the atmospheric light value associated with the low-resolution image to the input digital image to generate a de-hazed output image and displaying the generated de-hazed output image on a display unit.
