Abstract: A GaN-based thin film (thick film) is grown using a metal buffer layer grown on a substrate. (a) A metal buffer layer (210) made of, for example, Cr or Cu is vapor-deposited on a sapphire substrate (120).

A freestanding substrate can be fabricated by selective chemical etching of the substrate fabricated by the above steps. It is also possible to use the substrate fabricated by the above steps as a GaN template substrate for fabricating a GaN-based light emitting diode or laser diode.

Abstract: It is simpler to manage an electronic signature on a It is simpler to manage an electronic signature on a server. On the contrary, authentication in a paper is more conveniently managed by a serverless system. However, data embedded in a document relies on an authentication system and security system. In view of this, a security data extraction unit separates electronic data into security data and non-security data. An image arrangement unit arranges the non-security data on a paper surface and converts it to readable image data. An encryption processing unit encrypts the security data. An authentication program generation unit generates an authentication program that executes authentication using authentication data. A package unit packages the encrypted data and the authentication program. A background embedding unit generates background image data where the package data is embedded in a background pattern.

Abstract: An evaluation value for a pixel in an eye region in an image is computed, which is increased with increase in the redness of the pixel and with decrease in the luminance of the pixel. Furthermore, a color saturation value for the pixel included in the eye region is corrected with the use of a luminance value for a surrounding region around an eye and the evaluation value. In this case, the color saturation value is corrected such that the amount of correction is smaller in a case in which the luminance value is smaller even with the same evaluation value, thereby achieving improvement in the correction factor of and prevention of false corrections of a redeye region with a low color saturation and a low luminance.

Abstract: In continuous shooting processing, the defocus amounts of respective focus detection areas and the reliabilities of the defocus amounts are detected from information of the focus detection areas. Weightings are determined based on the reliabilities and defocus amounts. If the detection of defocus amounts is not completed in one shooting operation during continuous shooting, weightings are determined using defocus amounts detected in a shooting operation preceding the current one during continuous shooting. If there is no defocus amount that has been detected in a shooting operation preceding the current one, weightings are determined to weight a photometry area at a predetermined position of the field. A correct exposure for shooting is determined by calculating the weighted average of photometric values obtained in a plurality of photometry areas using the determined weightings. Continuous shooting can be performed with a correct exposure without decreasing the continuous shooting speed.
