Abstract: Convergence angle information and image information of video cameras is transmitted from a multi-eye image-taking apparatus having two video cameras through a recording medium to a displaying apparatus. A convergence angle of display units in the displaying apparatus is controlled in accordance with the convergence angle information of the video cameras, permitting an observer to observe natural images. Since the convergence angle information is made ahead of the image information, the convergence angle of the display units can be changed with a natural feeling.

Abstract: This invention provides a stereoscopic display apparatus which can discriminate image signals for the right and left eyes and can normally display an image without adding any special signals for discriminating the image signals for the right and left eyes. The basic principle of a stereoscopic display apparatus according to an embodiment of this invention will be described below with reference to FIGS. 2B and 2C. When the optical axes 210 and 211 of the photographing lenses are set to be parallel to each other, the position of the object image 201l in the field frame 212 is near the left end, and the position of the object image 201 in the field frame 213 is near the right end. In order to detect a relative positional relationship, in the right-and-left direction, of the object on the basis of the signal waveforms shown in FIG.

Abstract: There is provided an image pickup apparatus capable of operating only at the time of occurrence of moire and reducing the moire without the need to use an optical low-pass filter and without degrading image quality. The image pickup apparatus is provided with a circuit for detecting, from an output signal of an image sensor, the amount of aliasing distortion (moire) which occurs when sampling is performed at the pitch of pixels of the image sensor, and determining whether moire has occurred. On the basis of the detected amount of moire, the distance between a photographic lens and the image sensor is made to vary or electrical processing is applied to the output signal from the image sensor, thereby reducing the moire.

Abstract: A stereoscopic display apparatus discriminates image signals for the left and right eyes by comparing the received image signals, and displays an image without adding special signals for discriminating the left and right eyes. A mechanical connection between an image pickup and an image display is not needed to properly distinguish left and right eye images.

Abstract: A head-position controlling device includes a head moving mechanism for causing a head to move with respect to a recording track on a recording medium; a detecting circuit for detecting an amplitude of a reproduced signal which is reproduced from the recording track on the recording medium by the head; and a controlling circuit for controlling the head moving mechanism on the basis of an output of the detecting circuit. If so that if the amplitude of the reproduced signal is greater than a predetermined level, the head is made to move in units of a first moving amount to detect a position where the amplitude of the reproduced signal is a maximum, and if the amplitude of the reproduced signal is less than the predetermined level, the head is made to move in units of a second moving amount greater than the first moving amount. If the amplitude of the reproduced signal becomes greater than the predetermined level, the moving amount of the head is switched to the first moving amount.
