Image processing system, image processing apparatus and image processing method

A data management server that can prevent data stored in a user's folder on the server from being used by others when the user is not working, even in a client-server network environment. The data management server that manages data that can be used by multiple terminal devices, and constitutes a storage device in which separate storage areas are allocated for each user. A determination unit determines which of the terminal devices is in a state in which it is able to access the data management server. When a terminal device issues a request to access a separate storage area of the storage device, if it is determined by the determination unit that the terminal device of a user associated with the separate storage area is in a state in which it can access the data management server, an access management unit permits the requesting terminal device to access the data stored in the separate storage area. If the associated user's terminal device is not in such a state, the access management unit denies access to the data stored in the separate storage area. In an alternative embodiment, limited access for certain types of processes may be permitted when the associated user's terminal device is not in the access-enabled state.

In an image processing apparatus, an image reading unit reads a document put on a platen glass to generate image data, and a detector in the image reading unit detects offset, tilt angle and document area of the document put on the platen glass. A rotation angle is set based on the image data of a document. The entire document area is determined based on a portion of the document which exists within the image reading area when the document extends beyond the image reading area. The document area can be detected even if a document is not rectangular. For example, a slope of the document is determined based on the detected longest segment. In order to solve the unequal reading pitch, the longest segment is selected in the segments having a slope smaller than a predetermined angle relative to the subscan direction. Then, the image data are corrected according to the above result.
