Abstract: Moving images of a space, which includes objects 34 and 35 of a display target, as viewed from reference points are created in advance as reference images, and they are combined in response to actual positions of the points of view to draw a moving image. When the object 35 is displaced as indicated by an arrow mark in the space, reference points of view 30a to 30e are fixed as depicted in (a). Alternatively, the reference points of view are displaced in response to the displacement like reference points of view 36a to 36e in (b). Then, the moving images from the reference points of view are generated as the reference images.

Abstract: A differential amplifier circuit includes a basic differential amplifier circuit including an operational amplifier configured to amplify a potential difference between output ends of a first input resistor and a second input resistor, a feedback resistor connected to the output end of the first input resistor, and a first resistance element connected to the output end of the second input resistor.

Abstract: A current sensor for detecting a magnitude of a current flowing through a measuring object has a magnetic core having a first magnetic core and a second magnetic core that is arranged magnetically in parallel to the first magnetic core, wherein the first magnetic core has a magnetic permeability that is higher than that of the second magnetic core in a first frequency band, and the first magnetic core has a magnetic permeability that is lower than that of the second magnetic core in a second frequency band, the second frequency band being higher than the first frequency band, and the current sensor detects the magnitude of the current in a frequency band that is constituted by combining the first frequency band and the second frequency band.

Abstract: A current sensor includes an excitation detection winding configured such that an excitation signal for exciting a second magnetic core is input, the excitation detection winding detects magnetic flux flowing through the second magnetic core and outputs a detection signal indicating a measurement-target current. The current sensor includes an auxiliary winding that detects the magnetic flux and outputs an auxiliary signal indicating the measurement-target current. The current sensor includes a feedback winding wound around first and second magnetic cores, the feedback winding being configured such that a signal generated from the detection signal is input, and the feedback winding being wound to cancel out magnetic flux of the first and second magnetic cores. The current sensor includes a circuit to output an output signal indicating a level of the measurement-target current by modifying a signal output from the feedback winding based on a correction signal generated from the auxiliary signal.

Abstract: With respect to a space including an object 40 of a display target, images of the space viewed from reference points 42a to 42c of view are created as reference images 46a, 46b, and 46c in advance and they are synthesized according to a position of an actual point of view to render a display image. In the certain reference image 46b, data other than a part 48 represented only in it is deleted. At the time of rendering of the deleted part, the other reference images 46a and 46c are used.

Abstract: Moving images of a space, which includes objects 34 and 35 of a display target, as viewed from reference points are created in advance as reference images, and they are combined in response to actual positions of the points of view to draw a moving image. When the object 35 is displaced as indicated by an arrow mark in the space, reference points of view 30a to 30e are fixed as depicted in (a). Alternatively, the reference points of view are displaced in response to the displacement like reference points of view 36a to 36e in (b). Then, the moving images from the reference points of view are generated as the reference images.

Abstract: For a space including an object to be displayed, images of the space viewed from reference points of view are created in advance as reference images, and the reference images are combined according to a position of an actual point of view to draw a display image. In this case, a reference image not displaying reflection is used to determine the color of the object (S50). In a case of expressing reflection of another object (Y in S52), a position of the reflected object is estimated in a three-dimensional space (S54), a position on the reference image corresponding to the position is acquired (S56), and a color of the position is combined with the color of the object (S60).

Abstract: To achieve a balance between responsiveness of image display with respect to movement of a viewing point, and image quality. Reference viewing points are set in respect of a space containing an object to be displayed, and images of the space as viewed from these respective reference viewing points are created as reference images. Meanwhile, when pixel values of display images from a virtual camera are determined, reference images are selected wherein a point on the object represented by the pixel in question is represented as an image, and the values of these pixels are combined using a rule based on the positional relationship etc. of the reference viewing points with the virtual camera.
