ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an image processing apparatus and an electronic equipment when an image signal is transmitted from the electronic equipment and the image signal is printed by predetermined printing means through the image processing apparatus and also relates to a control method of them.
2. Related Background Art
In recent years, an image processing apparatus having a complex function in which a function as a copying apparatus and a function as a printer are simultaneously provided is known. Such an image processing apparatus has an image processing function such as a multivalue/binary conversion or the like in the image processing apparatus. However, when it operates as a printer function, a binary image signal before an image signal is received, namely, after a multivalue/binary conversion by a software process was performed on the host computer side is received and printed.
However, if the image signal is printed as mentioned above, there is a problem such that it takes a very long time until completion of the print in dependence on a performance of the host computer.
As a method of solving the above problem, as shown in
FIG. 13
, there is a method whereby a multivalue image signal (eight bits for each of RGB) which is transmitted from a host computer (PC) is once inputted to another hardware processing unit (IPU) and, after, the IPU performed the multivalue/binary conversion at a high speed, the signal is transmitted as a binary image signal (one bit for each of CMYKY to an image processing apparatus having a printer function.
However, according to the solving method as mentioned above, costs and a spade to install another unit (IPU) are further necessary.
SUMMARY OF THE INVENTION
The invention is made in consideration of the above prior art and it is an object of the invention that when both of an electronic equipment such as a host computer or the like and an image processing apparatus such as a printer or the like have a multivalue/binary conversion, a multivalue image signal which the electronic equipment has is efficiently converted to a binary image signal and printed.
To accomplish the above object, according to a preferred embodiment of the invention, there is provided an image processing apparatus for receiving an image signal from an external apparatus having binarizing means for binarizing a multivalue image signal by a software process, comprising: receiving means for selectively receiving the multivalue image signal or binary image signal from the external apparatus; binarizing means for binarizing the multivalue image signal received by the receiving means and outputting the binary image signal; and output means for outputting the binary image signal received by the receiving means or the binary image signal outputted by the binarizing means to predetermined printing means.
To accomplish the above object, according to another embodiment of the invention, there is also provided an electronic equipment for transmitting an image signal to a predetermined printing device having binarizing means for binarizing by a hardware process, comprising: generating means for generating a multivalue image signal; selecting means for selecting either one of a mode to transmit a binary image signal obtained by binarizing the multivalue image signal to the predetermined printing device and a mode to transmit the multivalue image signal to the predetermined printing device; binarizing means for binarizing the multivalue image signal by a software process and outputting a binary image signal; and transmitting means for transmitting the multivalue image signal or the binary image signal outputted by the binarizing means to the predetermined printing device in accordance with the result selected by the selecting means.
The above and other objects and features of the present invention will become apparent from the following detailed description and the appended claims with reference to the accompanying drawings.
