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). (b) A substrate obtained by vapor-depositing the metal buffer layer (210) on the sapphire substrate (120) is nitrided in an ammonia gas ambient, thereby forming a metal nitride layer (212). (c) A GaN buffer layer (222) is grown on the nitrided metal buffer layers (210, 212). (d) Finally, a GaN single-crystal layer (220) is grown. This GaN single-crystal layer (220) can be grown to have various thicknesses depending on the objects. 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: An image-pickup apparatus is disclosed which can prevent focus control from being performed on the basis of incorrect information on an object distance externally measured. The image-pickup apparatus includes a first detector which produces first information corresponding to a contrast state of a picked-up image, a second detector which receives light from an object to detect second information corresponding to a distance to the object, and a controller which performs focus control by using the first information and the second information. The controller performs the focus control by using the first information without using the second information when a light-receiving luminance level in the second detector is lower than a first value.
Abstract: An object of this invention is to limit a correction amount for correcting the exposure error of a photographed image so as to prevent an excessively corrected image sensing result, and obtain a desired image sensing result by changing the correction width of the correction amount in accordance with the setting state and operation state of an image sensing apparatus and the object brightness in image sensing. To achieve this object, an exposure error value is calculated from the exposure level of an image signal and an exposure level obtained by photometry. The correction amount of the exposure error value is calculated on the basis of at least one of the setting state of the image sensing apparatus, the operation state of the image sensing apparatus, and the object brightness state in image sensing. The exposure error of the sensed image is corrected using the correction amount.
