    摘要： A fuel injection amount control system for an internal combustion engine includes an ECU which calculates a desired amount of fuel to be supplied to each combustion chamber in response to operating conditions of the engine, and calculates values of parameters indicative of fuel adherence characteristics of the interior of the intake passage in response to operating conditions of the engine. The ECU further calculates a first fuel amount which is directly drawn into the combustion chamber from a fuel amount injected by the fuel injection valve, and a second amount of fuel which is carried off the wall surface of the intake passage due to evaporation and drawn into the combustion chamber, based upon the values of the parameters. The ECU calculates an injection amount of fuel to be injected, by correcting the desired fuel amount, based upon the first and second fuel amounts. When the engine is in a predetermined operating condition in which convergence of the fuel injection amount calculated by the ECU to the desired fuel amount can be unstable, the value of at least one of the parameters such that the fuel injection amount stably converges to the desired fuel amount.

    摘要： When creating a marker, an encryption apparatus extracts each pixel value in a region and allows a storing unit to save, as restoration information, the high-order bits of each extracted pixel value. Then, the encryption apparatus creates a marker by changing the high-order bits of the pixel value in a region in which the marker is created and embeds encrypted information in an encrypted region specified by the marker. When decoding the encrypted information, a decoding apparatus detects the marker from a digital image, decodes the encrypted information in the encrypted region specified by the marker, and overwrites bits contained in the restoration information with the high-order bits of the pixel value of the marker.

    摘要： An image processing apparatus includes: an interface unit for acquiring a readout image produced by capturing an image formed on a medium; a storage unit for storing a plurality of templates generated by superimposing different amounts of blurring on a prescribed pattern contained in the image, and for storing the amounts of blurring superimposed on the respective templates; and a processing unit adapted to detect a pattern region where the prescribed pattern is located on the readout image, calculate the degree of matching between the pattern region and each of the plurality of templates and, based on the degree of matching, identify a template that most closely matches the prescribed pattern located on the readout image, and estimate that the amount of blurring corresponding to the most closely matching template represents the amount of blurring superimposed on the readout image.
