    摘要: A beam diameter varying portion varies a first beam diameter of a measuring beam incident on an optical portion to a second beam diameter larger than the first beam diameter. An adjustment portion adjusts a condensing position of the measuring beam on the optical portion based on intensity information of a return beam from a position of an inspection object with the first beam diameter. The beam diameter is varied from the first to the second beam diameter by the beam diameter varying portion at the position adjusted by the adjustment portion to cause the measuring beam having the second beam diameter to be incident. A condensing position can be adjusted in a relatively short time because the measuring beam small in beam diameter is used, and a combined beam can be acquired with high transverse resolution because the measuring beam large in beam diameter is used.

    摘要: Provided is an image acquisition apparatus for acquiring a 3D retinal image with high resolution, which is capable of reducing a time period required for data transmission. In the image acquisition apparatus: a blink of a subject is detected; acquisition of image taking data is suspended thereafter until a line of sight becomes stable; and the data transmission to a computer is started at a timing at which a blink has been detected, thereby avoiding acquiring unnecessary data, allowing a capacity of a data buffer to be smaller, and making the data transmission efficient.

    摘要: An image forming apparatus for adjusting image density includes an input device for inputting a plurality of image type information and a discriminating device for discriminating the image type information in accordance with a signal other than a signal to be recorded. An image forming circuit, such as a printer, forms an image on the basis of image type information. A density adjusting circuit adjusts the image forming density of the image forming circuit in accordance with the input image type information. The discriminating device inputs a signal indicative of whether the input image type information indicates a text image or a graphics image, or whether it denotes Japanese or a European language (e.g., English). The discriminating device also inputs a signal indicative of the kind of font included in the input image type information or a signal indicative of a resolution for an output image to be formed by the printer.
