Abstract

An information processing apparatus having a power-saving standby power mode, according to an embodiment of the present invention, first communicates with an image reading device configured to read an image from an original and receives image data obtained in the reading of the image. In a case where a reading operation does not normally terminate because the information processing apparatus changes to a power-saving state during the reading operation and it is confirmed that the image processing apparatus has returned from the power-saving state, the information processing apparatus instructs the image reading device to discard the received image data of an image that was being read from an original when the information processing apparatus shifted to the power-saving state, and re-read the image that was being read from the original.

First claim

What is claimed is:

1 . An information processing apparatus that has a power-saving standby power mode, comprising:
a communication unit configured to communicate with an image reading device configured to read an image from an original; and an instruction unit configured to instruct the image reading device via the communication unit, in a case where a reading operation does not normally terminate because the information processing apparatus changes to a power-saving state during the reading operation and it is confirmed that the information processing apparatus has returned from the power-saving state, to discard image data of an image which was being read from an original when the information processing apparatus shifted to the power-saving state and re-read the image which was being read from the original.

2 . The apparatus according to claim 1 , further comprising a display unit configured to display a message notifying a user of re-reading of the image.

3 . The apparatus according to claim 2 , wherein the display unit further displays a message prompting one of reading of another original and a termination instruction of the reading operation in a case where the reading operation in the image reading device has been normally terminated.

4 . The apparatus according to claim 2 , wherein the display unit further displays a message indicating that communication with the image reading device is disabled.

5 . The apparatus according to claim 1 , further comprising a confirmation unit configured to confirm the return from the power-saving state, based on a return event from an operating system operating in the information processing apparatus.

6 . The apparatus according to claim 1 , further comprising a setting unit configured to set a reading condition of the image in the image reading device,
wherein the instruction unit instructs the image reading device to perform image reading, based on the reading condition set by the setting unit.

7 . The apparatus according to claim 6 , wherein the instruction unit instructs the image reading device to perform re-reading of the image which was being read from the original, based on the reading condition set by the setting unit.

8 . The apparatus according to claim 5 , further comprising an initialization unit configured to initialize the image reading device after the return from the power-saving state is confirmed by the confirmation unit in a case where the image reading device is operated by power supply from the information processing apparatus,
wherein the instruction unit instructs, after the initialization by the initialization unit, re-reading of the image which was being read from the original.

9 . The apparatus according to claim 8 , further comprising a connection unit configured to connect the image reading device by a USB interface,
wherein the image reading device is a USB-powered device to which power is supplied via the USB interface.

10 . The apparatus according to claim 1 , further comprising a generation unit configured to generate a single multi-page image file by continuously reading a plurality of originals in the image reading from the originals.

11 . A non-transitory computer readable storage medium which stores a computer program to be executed in a processor of an information processing apparatus that has a power-saving standby power mode, the program comprising:
communicating with an image reading device configured to read an image from an original and receiving image data obtained in the reading of the image; and instructing the image reading device by communicating with the image reading device, in a case where a reading operation does not normally terminate because the information processing apparatus changes to a power-saving state during the reading operation and it is confirmed that the information processing apparatus has returned from the power-saving state, to discard the received image data of an image which was being read from an original when the information processing apparatus shifted to the power-saving state, and re-read the image which was being read from the original.

12 . An information processing method of an information processing apparatus that includes a power-saving standby power mode, comprising:
communicating with an image reading device configured to read an image from an original and receiving image data obtained in the reading of the image; and instructing the image reading device, in a case where a reading operation does not normally terminate because the information processing apparatus changes to a power-saving state during the reading operation and it is confirmed that the information processing apparatus has returned from the power-saving state, to discard the received image data of an image which was being read from an original when the information processing apparatus shifted to the power-saving state, and re-read the image which was being read from the original.

13 . The method according to claim 12 , further comprising displaying a message notifying a user of re-reading of the image on a display screen.

14 . The method according to claim 13 , further comprising displaying a message prompting one of reading of another original and a termination instruction of the reading operation on the display screen in a case where the reading operation in the image reading device has been normally terminated.

15 . The method according to claim 13 , further comprising displaying, on the display screen, a message indicating that communication with the image reading device is disabled.

16 . The method according to claim 12 , further comprising confirming the return from the power-saving state, based on a return event from an operating system operating in the information processing apparatus.

17 . The method according to claim 12 , further comprising setting a reading condition of the image in the image reading device,
wherein in the instructing, the image reading device is instructed to perform image reading, based on the reading condition set in the setting.

18 . The method according to claim 17 , wherein in the instructing, the image reading device is instructed to perform re-reading of the image which was being read from the original, based on the reading condition set by the setting unit.

19 . The method according to claim 16 , further comprising initializing the image reading device after the return from the power-saving state is confirmed in the confirming in a case where the image reading device is operated by power supply from the information processing apparatus,
wherein in the instructing, after the initialization, re-reading of the image which was being read from the original is instructed to the image reading device.
