Abstract: An information processing apparatus capable of changing packet patterns for determining, based on a condition of proxy ARP compatibility of a connected wireless LAN access point, communication requests to which the apparatus can respond in a power saving state, and thereby maintaining the power saving state for a longer time period. A RAM of an MFP operable in the normal state and the power saving state stores packet patterns which enable the MFP to respond to packets received in the power saving state while maintaining the power saving state. The MFP acquires proxy ARP support information from a wireless LAN access point that relays communication between the MFP and an external apparatus. The MFP determines whether or not the AP can respond to a received communication request on its behalf, and changes the packet patterns based on the determination result.

Abstract: An image forming apparatus that determines whether an image having coincidence with a registered image is included in an input image and controls execution of a job that uses the input image based on a result of the determination. The image forming apparatus includes an input unit that inputs a first image as a candidate of the registered image, an evaluation unit that evaluates whether the first image is suitable for use in the determination, and a control unit registers the first image as the registered image if the evaluation unit evaluates that the first image is suitable for use in the determination, and prevents the first image from being registered as the registered image if the evaluation unit evaluates that the first image is unsuitable for use in the determination.

Abstract: An image processing apparatus comprises: an obtaining unit configured to obtain image data of an original read by a reading unit; a detection unit configured to detect an object from the image data; a color determination unit configured to determine whether an object detected by the detection unit is a color image or a monochrome image; a conversion unit configured to convert each object determined to be a monochrome image by the color determination unit into a color image; and a display unit configured to perform a display, for each object converted by the conversion unit, in which editing by a user is possible.

Abstract: An image processing method includes determining whether image data acquired by reading a document with a reading unit is color or monochrome, saving color image data determined to be color and monochrome image data generated by monochrome conversion of the color image data, in association with each other as a learning sample, deciding a color conversion parameter to be used when image data read by the reading unit and determined to be monochrome image data is converted into a color image, using the saved learning sample, and converting the image data read by the reading unit and determined to be the monochrome image data into color image data, using the decided color conversion parameter.

Abstract: An information processing apparatus that can avoid an IEEE802.1X re-authentication process due to a communication speed setting change made at the time of transitioning to the power-saving state and realize both of security and power-saving. Fixed link speed with which both a MFP 100 and a communication apparatuses are compatible is set on the basis of acquired pieces of link speed setting information about the MFP 100 and the communication apparatus. Then, 100 Mbps lower than 1000 Mbps is fixedly set on the basis of acquired power-saving setting information about the MFP 100 when the power-saving setting is effective, and EEE is enabled.

Abstract: In an image processing apparatus which generates an input signal when a mobile information terminal contacts a display surface and makes a wireless communication with the contacting mobile information terminal, it is difficult to make an appropriate display by discriminating whether a contact object is a mobile information terminal or a user's finger. To accomplish this, when a mobile information terminal (200) is placed on a touch panel (104), this placement is recognized based on a wireless communication response (701), and a processing menu for the terminal is displayed. On the other hand, if the user's finger (300) is placed, since no wireless communication response (701) is detected, it is recognized that the contact object is not the mobile information terminal (200), and a general manipulation menu is displayed.
