Abstract: Provided is an information processing apparatus that, whichever of a web application and a native application is being executed when a specific hard key is operated, make uniform a function executed by operating the hard key. When processing is executed by communicating with the web application on a web server, and the operation is performed by the hard key included in the information processing apparatus, the web server is notified of identification information for identifying the hard key, and an operation screen is displayed based on screen information received from the web server that has been notified of the identification information.

Abstract: An image forming apparatus capable of performing control so as to prevent a line registration error from occurring, even if a timing to start counting a positional deviation becomes different between color plane images. A BD identification unit of the image forming apparatus identifies whether a main scanning sync signal is a sync signal for odd-numbered line or for even-numbered line, and outputs a first or second timing edge signal. According to the timing edge signal, a sub-scan timing controller controls an output timing of an image signal to a printer controller. When the top of a page is detected based on the timing edge signal first input from the BD identification unit, the sub-scan timing controller is made enabled. If the first timing edge signal is subsequently input, the image signal output timing is controlled according to the second timing edge signal which is next input.

Abstract: A program that is to be preferentially loaded into a memory is stored in a specific memory and the program stored in the specific memory is changeable to another program. Thus, the program that is to be preferentially loaded into the memory is thereby made changeable.

Abstract: An image processing apparatus is configured to extract paper-fingerprint information from a printing sheet and to identify unique information unique to the printing sheet and attached to the printing sheet. The image processing apparatus is further configured to compare the identified unique information associated with the printing sheet with previously registered unique information and to store the unique information and the extracted paper-fingerprint information in association with each other when it is determined that the identified unique information matches the previously registered unique information.

Abstract: An image processing controller suspends an operation of hardware when receiving instructions of an interrupt of an event that should be executed with higher priority than rendering, such as a copy job, during execution of rendering by the hardware. Then, an information processing controller executes the rendering, which was being executed by the hardware, by software. Accordingly, even if an interrupt to suspend the operation of the hardware occurs during rendering by the hardware, the rendering can be completed as quickly as possible without waiting for restart of the operation of the hardware.

Abstract: The present invention provides a mechanism for re-registering a paper fingerprint that may change. A configuration for this includes: a extracting means that extracts a paper fingerprint of a sheet surface and coded information on the paper fingerprint; a means that decodes the coded information extracted by the extracting means; a matching means that matches paper fingerprint data decoded by the decoding means with data of the extracted paper fingerprint; and a re-registration prompting means that performs a display to prompt a re-registration based on a result of matching by the matching means.

Abstract: An image processing apparatus has a plurality of functions and is adapted to make one or more functions operable by activating programs corresponding to functions. The image processing apparatus includes a selection unit adapted to select a function to be enabled in advance to the other functions when power of the image processing apparatus is turned on or when operation of the image processing apparatus is resumed from a low-power standby state, and a control unit adapted to perform control such that a program corresponding to the function selected by the selection unit is made executable in advance to the other programs.
