Abstract: A shape measuring apparatus (1) measures a workpiece shape utilizing white light interference, and includes a stage (10) on which a workpiece (W) is placed, an interference optical system (100) that irradiates the workpiece (W) with white light (WL) to generate a white light interference moire, a drive unit (26) that moves one of the stage and the interference optical system in a direction of an optical axis, a length measuring device (50) that measures a relative distance (L) between the stage and the interference optical system changed by the drive unit, and an imaging unit (40) that images the white light interference moire to acquire contrast information of the white light interference moire that changes according to the relative distance.

Abstract: A digital camera provided with an image pickup device; a readout controller for the electrical signals accumulated; a section to acquire image information according to the electrical signals readout; a controller for displaying images based on the image information; and a processor to output electrical signals accumulated in a first output area within an image capturing area at a first speed and to output electrical signals accumulated in the second output area at a second speed higher than the first speed; wherein the information of a predetermined area within the first output area is acquired during the signal output processing, and a moving image based on the image information of the predetermined area is displayed in a display area corresponding to the predetermined area during the signal output processing, and a still image is displayed in the other display area.

Abstract: An image pick-up apparatus includes: an image pick-up device for picking up an object image by converting the object image to an electric image signal; an image pick-up optical system having a variable aperture capable of changing an aperture value when an incident light beam on the image pick-up device is stopped down; a range-finder for measuring a distance to an object; an electronic flash mechanism for illuminating the object; and controller for determining an aperture value from the distance to the object measured by the range-finder and from a light emission capability of the electronic flash mechanism, and then for setting the variable aperture to the determined aperture value, when the controller makes the electronic flash mechanism to emit light so that the image pick-up device picks up the object image.

Abstract: A camera for photographing by exposing a silver halide film, includes: a silver halide photographing device having a lens and a shutter wherein a photographing is conducted by exposing the silver halide film through the lens and the shutter; and an electronic viewfinder having a solid-state image sensor and a direct-vision type image displaying section, for displaying an image picked up by the image sensor on the direct-vision type image displaying section. The image displaying section of the electronic viewfinder is disposed on a rear side of a main body of the camera.

Abstract: A zoom camera being capable of changing a distance measuring direction to measure an object distance, and more particularly a camera which indicates the distance measuring direction overlapped on an object image in a view finder display. An object image is displayed in a finder display through an optical system, thereby the magnification of the object image in the view finder changes in accordance with a zooming of the camera. An indicator array is arranged on the view finder display, and the distance measuring direction is indicated by an activation of an indicator element of the indicator array located at a corresponding position to an object position in the distance measuring direction.
