Provided are a digital image signal processing method including determining a saturation condition by comparing a delta between a plurality of pieces of image data of an input image exhibiting different color components with a standard for white scene recognition, determining a bright condition by using a distribution of grey levels of the input image, and determining that the input image is a white scene when the input image satisfies the saturation condition and the bright condition, and a digital image signal apparatus for executing the method, and a medium having recorded thereon the method. Thus, a white scene is quickly and accurately determined. And settings of the digital image signal processing apparatus can be properly set for capturing the white scene.
