摘要:
An information processing system includes an information processing apparatus and a display apparatus including an imaging unit. The display apparatus superimposes an image of a first processing apparatus not having a predetermined function, captured by the imaging unit, and an image of a second processing apparatus having the predetermined function to display the superimposed image, and sends an image captured by the imaging unit to the information processing apparatus. The information processing apparatus performs processing for providing the predetermined function, when detecting, from the captured image received from the display apparatus, that a user of the first processing apparatus has performed an operation for using the predetermined function.

This invention provides a technique of preventing determination of image alteration when digital image data has undergone, e.g., rotation without any substantial change in contents. To do this, an area separation processing unit separates image data into areas. For each of the separated areas, an area feature value calculator calculates an area feature value independent of the coordinate information of the image. An area order sorter sorts the separated areas in accordance with the calculated area feature values. A validation data generation processing unit generates validation data based on the sort result.
摘要:
In verification of image data of a captured image as to whether it is original one, the verification is possible even for image data subjected to a peripheral illumination correction or an exposure correction. An order information calculation unit selects a pixel set including two or more pixels based on pixel values and information on an image space of image data of a captured image, and calculates an order of magnitude between pixels in the selected pixel set. A verification data producing unit generates verification data used in verification of whether the image data has not been tampered with, based on the calculated order of magnitude. An image output unit outputs the image data and the verification data.

The invention enables a verifier to easily confirm that the image data was captured in the multiple exposure mode, and also to easily confirm which area in the image captured in the multiple exposure mode was greatly affected by multiple exposure. An image generating unit generates exposure image data pieces by exposing an image sensor a plurality of times. An image composition unit combines exposure image data pieces to generate a single piece of composite image data. A reference image generating unit generates reference image data composed of data pieces for distinguishing pixel positions at which the exposure amount exceeds a threshold from the other pixel positions. A verification data generating unit generates verification data for determining whether alteration has been made from the composite image data and the reference image data to output a single file.

An information processing apparatus includes a scanning unit adapted to scan an image of a document, a detection unit adapted to detect a document type by analyzing image data of the document scanned by the scanning unit, a storage unit adapted to store a storage period for each document type, a calculation unit adapted to calculate an expiration date for storage of the image data based on the storage period corresponding to the document type detected by the detection unit, and a management control unit adapted to manage the image data based on the calculated expiration date for storage.
摘要:
Fuel injection is started through a first one of fuel injection valves, and a time counter counts a period of time elapsed from the start of fuel injection through the first one valve. Fuel injection is started through a second one of the fuel injection valves when a predetermined period of time elapses after the start of fuel injection through the first one valve. The fuel injection through the first one valve is terminated in response to completion of counting of the time counter, and the time counter is restarted to count a difference between a desired fuel injection period of time for the first one valve and a desired fuel injection period of time for the second one valve. The fuel injection through the second one valve is terminated in response to completion of counting of the restarted time counter.
