Abstract
There is provided an image processing apparatus for executing a process to an input image in accordance with the characteristics thereof, comprising: an input device to input image data; a detector to detect the characteristics of the input image; and a processor to execute first and second processes such as brightness correcting processes or color balance correcting processes for the input image data on the basis of weights corresponding to the characteristics of the input image. When the weight of the first process is large, the weight of the second process is set to a small value. As the characteristics of the input image are deviated from a predetermined condition, the processor sets the weight of the first process to a small value and sets the weight of the second process to a large value. With the apparatus, the brightness and the color balance of the input image are preferably corrected and a natural image can be output irrespective of the characteristics of the image reading apparatus.
