An image dividing means 2 analyzes the texture of input image, and on the basis of result of analysis it fully automatically divides the input image into a plurality of division areas. A density conversion curve generating means 3 determines a clip value for each division area on the basis of the broadness of dynamic range for determining a density histogram smoothing degree and generates a cumulative density histogram by using the determined clip valve for clipping. A density converting means 4 executes a density conversion process specific to each pixel in each division area, and outputs the result to an image output side apparatus. Thus, it is possible to permits automatically reducing loss of data outputted from an electronic imaging device to a monitor, a printer, etc. |
