ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an image processing device including a plurality of image processing means each having a particular function.
A color image recording apparatus including image processing means having a plurality of functions is disclosed in, e.g., Japanese Patent Laid-Open Publication No. 2-67076. The functions assigned to the image processing means include shading correction, positional deviation correction, MTF (Modulation Transfer Function) correction, magnification change, gamma correction, color correction, UCR (Under Color Removal), and tonality processing. While two or more of such functions can be executed in combination, they are executed only in a preselected order, i.e., signals are transferred in a preselected order. Let this kind of control be referred to as sequential control. The problem with the sequential control is that it needs a complicated input system and a complicated output system and cannot deal with simultaneous requests each requiring a particular function. This is particularly true with a digital copier often combined with a facsimile apparatus or a printer in order to meet a variety of needs. In addition, functional limitations are not avoidable when the functions are complicated, when a plurality of inputs and a plurality of outputs occur at the same time, or when a plurality of functions are required at the same time.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an image processing device capable of processing an image efficiently without any functional limitation even when the functions are complicated, when a plurality of inputs and a plurality of outputs occur at the same time, or when a plurality of functions are required at the same time.
In accordance with the present invention, an image processing device has at least two image inputting means each for inputting a digital image, at least two image outputting means each for outputting a digital image, a plurality of image processing means each having a particular image processing function, and control means for combining the image processing means in accordance with a requested mode.
Also, in accordance with the present invention, an image processing device has at least two image inputting means each for inputting a digital image, at least two image outputting means each for outputting a digital image, a plurality of image processing means each having a particular image processing function, managing means for managing the image processing means divided into groups, and control means for combining the groups in accordance with a requested mode.
Further, in accordance with the present invention, an image processing device has at least two image inputting means each for inputting a digital image, at least two image outputting means each for outputting a digital image, a plurality of image processing means each having a particular image processing function, managing means for managing the image processing means on an input and output basis, and control means for controlling the image processing means managed on an input and output basis in response to a requested mode.
