Abstract
An image processing apparatus capable of reducing noise contained in input image data. By determining whether or not, among the absolute values of the AC components of luminance Y, there is at least one value greater than a threshold value A, it is determined whether the components are effective edge components of the image or noise components. When it is determined that the components are effective edge components of the image, a suppress_flag is set to '0' so that a suppression process is not performed. When it is determined that the components are noise components, the suppress_flag is set to '1' so that a suppression process is performed. The present invention can be applied to a video camera for capturing an image of a subject.
