ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an image processing apparatus and method.
An image processing system which reads an image using a scanner, performs a predetermined image processing on the read image using an image processing apparatus, such as a personal computer, and outputs the processed image to a monitor or a printer has been commonly known. In such the system, the resolution of the scanner is generally fixed, and an image to be processed is read in this fixed resolution.
Accordingly, in an ordinary image processing system which outputs an image in different resolutions when printing the image and when displaying the image, a scanner capable of reading the image in either the resolution used for printing or the resolution used for displaying is used in order to reduce processes of resolution conversion.
When outputting an image in a resolution which is different from that used when reading the image, the resolution of the image is converted by performing thinning or interpolation processing.
The resolution conversion is performed while outputting the image in most cases, therefore, the image processing apparatus has to perform the resolution conversion in synchronization with output timing, which is a considerable load on the image processing apparatus.
SUMMARY OF THE INVENTION
The present invention has been made in consideration of the above situation, and has as its object to provide a high-quality image processing apparatus and method capable of effectively designating image processes when outputting an image in a plurality of resolutions after performing the image processes designated for the image by an operator, as well as outputting the processed image at high speed.
Further, it is another object of the present invention to provide an image processing system, comprising a server and a terminal, capable of minimizing the amount of data transmitted between the server and the terminal as well as performing desired image processes on an image stored in the server in response to an operation by an operator performed in the terminal, further outputting a resultant image from the server.
Other features and advantages of the present invention will be apparent from the following description taken in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the figures thereof.
