In a control method for a processing apparatus connected to an image reading apparatus, in a case where the processing apparatus receives a cancellation instruction while the image reading apparatus performs a reading step, the processing apparatus causes the image reading apparatus to terminate the reading step and deletes image data of a page being read, and in a case where the processing apparatus receives a cancellation instruction after the image reading apparatus has performed the reading step, the processing apparatus performs controlling processing for deleting image data that has been acquired in the last reading step and has yet to be stored.

Image processing method and computer-readable storage medium

According to an embodiment of this invention, in a system including an image reading apparatus and a server, the image reading apparatus and the server can efficiently cooperatively perform image processing with a simple arrangement. More specifically, the image reading apparatus reads an image of an original, upon receiving an image reading instruction from a user terminal via the server, according to the instruction. The apparatus analyzes whether image processing included in the instruction is executable. If executable image processing exists, the apparatus executes the image processing for image data obtained by reading the image of the original. The image data of the original or image data that has undergone the image processing is transmitted to a transmission destination together with information representing whether the image processing included in the instruction has been executed.

To read a plurality of pages, it is necessary to notify a server of completion of transfer from an image reading apparatus and transmit a next page reading input instruction from an operation terminal to the image reading apparatus again via the server. In the above reading operation, time from completion of original reading to the start of reading of the next original is prolonged, and user operability lowers. According to an embodiment of this invention, when reading images of a plurality of pages, the first image reading instruction is input from a user terminal. After that, original placement, reading start instruction, and the like for the next page are performed from an input unit provided in the image reading apparatus. This can reduce the network communication amount and improve the throughput and user operability.

Status information representing the status of a device which performs predetermined processing is acquired from the device. The acquired status information is stored in a memory. The status information is output in response to input of a request to output the status information of the device. When the request is input after the lapse of the first time from the time corresponding to acquisition of the status information stored in the memory, status information is newly acquired from the device in accordance with the request, and the status information already stored in the memory before the input of the request is output.

System that outputs status information representing a status of a device

When a notification, indicating that a read-start instruction is inputted in a reading apparatus that supports event push scanning, is received through a network, read-setting of read operation corresponding to the read-start instruction is acquired from the reading apparatus through a network, in response to the received notification. An instruction is given to the reading apparatus through the network to read an image in accordance with the acquired read-setting and transmit read image data generated by the reading, using a predetermined scanner driver.

An image processing apparatus which detects a plurality of image areas included in an original plate image to extract a minimum rectangular area including the plurality of image areas, specifies maximum eight line segments acquired by extending four sides of the rectangular area toward corresponding four sides of the original plate image, respectively, extracts pixels existing in a neighborhood area including each of the specified line segments, and determines that the rectangular area and the minimum rectangular area including the extracted pixels are the areas of the original image. With the configuration, the image processing apparatus can accurately decide only an original area even if edge information of an original extracted from a read image is unclear.

Image processing apparatus, method, program and storage medium for determining an image area read by a reading device corresponding to an original image area

There is provided an image processing method which determines the area of a document from an image read on a transparent platen, the image processing method also determines a single object area or a plurality of object areas from the image on the transparent platen, and when the luminance of the area in which the object area is removed from the image on the transparent platen is detected to determine the document area, the image processing method detects whether or not an image of a shadow exists around the periphery of the object area on the image of the transparent platen, and the threshold value used for determining the document area is different depending on whether a shadow is detected.

An image processing apparatus has a multi-cropping function that automatically crops the scanned images of a plurality of original sheets placed on a platen of an image reading apparatus all at one pass. The desired number of cropped images is input by the user, and the number of cropped images detected when cropping the image of the original sheets placed on the platen, are compared.

Image processing apparatus and its program and control method

In a control method for an image reading system comprising an image scanning apparatus selectively reading an original as a reflective or transmissive original, an image processing apparatus receiving image data read by the image scanning apparatus and executing image processing of the image data, an operating unit, and a display unit. The control method includes determining whether the original is the reflective or transmissive original, executing reading of the reflective or transmissive original based on the determination result, processing the read image data, displaying details of processing executed and the image processing, and inputting an instruction to change the details of displayed processing. When the change instruction input instructs change of a process under execution or having been already executed, the image processing is executed again from the changed process.

Control method for image reading system

In a method for reading a document set on a document positioning plate to output image data, an edge area of an image of an entire reading area is extracted to form a first rectangle area including the extracted edge area. If a position of an apex of the first rectangle area farthest from a reading reference position and a size of the first rectangle area satisfy predetermined conditions, image data corresponding to a second rectangle area including the first rectangle area and the reading reference position are output.

This invention provides a method of connecting a network-connected image input device, to which a plug-and-play function cannot be applied to a computer installed with an OS (operating system) and using the image input device. To this end, when a control program of the image input device is activated, the program notifies the OS of information indicating that the peripheral device is connected, irrespective of connection/non-connection between the peripheral device and the computer. Upon reception of a command for activating the peripheral device, the control program confirms the connection/non-connection between the peripheral device and the computer. When the connection is confirmed, the control program controls the peripheral device to activate.
