## Abstract

An image processing apparatus implements appropriate image processing on image data stored in a storage unit of the image processing apparatus easily and efficiently, and distributes the image data to an external apparatus. An image format conversion unit implements image processing such as resolution conversion processing, filter processing, γ correction processing, and halftone processing on image data stored in an HDD serving as an image data storage unit so that the image data conform to conditions, such as image quality and format, specified by an external client apparatus. The image-processed image data are then distributed to the external client apparatus.

## Claims

### Claim 1

An image processing apparatus configured to connect to a client apparatus via a network, comprising:
image reading means for reading an original image and generating an image signal;
image processing means for implementing predetermined image processing on said image signal generated by said image reading means;
storage means for storing a plurality of image data compressed in various compression formats associated with functions of the image processing apparatus, the plurality of image data including image data subjected to said image processing by said image processing means;
image format converting means for converting said plurality of image data compressed in said various compression formats stored in said storage means into a format which conforms to attributes of image data handled by said client apparatus, said image format converting means converting said image data stored in said storage means into said format which conforms to said attributes of said image data handled by said client apparatus in response to a request for said image data stored in said storage means from said client apparatus; and
transmitting means for transmitting said image data subjected to format conversion by said image format converting means to said client apparatus over the network.
