摘要:
A partially coherent light beam from a light source is split between a probe light beam toward an observation object and a reference light beam toward a fixed reflective surface. The frequency of the probe light beam is shifted by optical-modulation means. The probe light beam whose frequency has been shifted is swept in a direction of an optical axis and in a direction orthogonal thereto to scan the object two-dimensionally. Reflected light beam from the object is combined with the reference light beam to generate interference light. A detector receives a time-based interference signal from the interference light obtained from the movement of the probe light beam in the direction of the optical axis and the sweeping in the direction orthogonal to the optical axis to derive therefrom reflection intensity data of the object. In such a configuration, the mechanically moving portion is disposed in the probe optical path. Therefore, changes in the interference characteristics of the light that accompany the mechanical scanning are less likely to occur and optical adjustments are also made easy.

When execution of copying of video and audio from a DVD from a videotape is instructed, a video copying apparatus 1 detects the remaining amount of the videotape set in a apparatus and reproduction time of video and audio copied to the videotape and based on these, it is determined whether the video and audio are recorded on the videotape in a standard mode or a longer-recording mode. Also, when execution of copying of video and audio from a videotape from a DVD is instructed, free space of the DVD and reproduction time of video and audio copied to the DVD are detected and based on these, a compression ratio of the video and audio recorded on the DVD is determined.

For forming an annular magnetostrictive coat on an outer peripheral surface of a rotational shaft associated with a magnetostrictive torque sensor, a magnetostrictive-coat forming method comprises a step of fitting a cylindrical masking jig over the outer peripheral surface of the rotational shaft and securing the masking jig to the outer peripheral surface, a step of placing the rotational shaft in a plating tank to thereby form the magnetostrictive coat by plating on the outer peripheral surface, and a step of detaching the masking jig from the rotational shaft.

A photography device has an AF mechanism including: a CCD; an analog signal processing section; an image input controller; an AF processing section; a CPU; and a focusing lens driving section. The AF mechanism operates to focus an imaging lens on a subject. If an image represented by output from the CCD does not include a specific low contrast subject, image data representing the image is passed through a first high frequency filter that transmits components having frequencies greater than or equal to a first cutoff frequency, and a focus evaluation value is determined based on the transmitted components. If the image includes the specific subject, the image data is passed through a second high frequency filter that transmits components having frequencies greater than or equal to a second cutoff frequency, lower than the first cutoff frequency, and a focus evaluation value is determined based on the transmitted components.

An image processing device is disclosed that classifies images in an image database and displays the classified images for searching, and is able to easily narrow a range of candidate images and improve operability. The image processing device includes a first classification unit, a display image controller that generates a display image for displaying a status of the classification performed by the first classification unit; a second classification unit that enables a user to select one or more categories included in the display image, and classifies image documents included in a selected category; a detection unit that detects a searching status; and a classification key selection unit that selects a classification key for the second classification unit in response to detection results of the detection unit.
摘要:
A similarity calculation processing unit calculates a similarity between a query image and each of a plurality of retrieval target images by using a layout feature amount and an image-property feature amount relating to the query image and the retrieval target image, and ranks the retrieval target images in descending order of similarity. When calculating the similarity, the layout feature amount is assigned with a heavier weight than the image-property feature amount.
摘要:
To realize sound output so that a listener does not feel unnaturalness, an audio signal for a center speaker is multiplied by a transfer function for a left speaker and a transfer function for a right speaker, respectively, and an audio component for a left center speaker and an audio component for a right center speaker that correspond to a listening point are generated. An audio signal for the left speaker and an audio signal for the right speaker are synthesized with the audio component for the left center speaker and the audio component for the right center speaker, respectively. Thereby, a sound image can be oriented as if a sound based on the audio signal for the center speaker is emitted from a position at which a center speaker would be set if the system had a center speaker.

The present invention relates to an image-taking apparatus such as a digital camera which is equipped with a release button and shoots a still image when the release button is pressed. It can perform proper metering for still images and reduce a time lag between a half press and the time when it is ready to shoot a still image. The image-taking apparatus has a through image display section which displays a through image which is moving images for display before a half press, a metering section which performs both metering for a through image and metering for a still image before the half press, a distance measuring section which measures distance in response to a half press, and a shooting section which shoots a still image in response to a full press.
