摘要： A guide device for an A.G.V. in which a magnetic field generated around a guide cable is detected by a pair of detection coils at both sides of the guide cable, and wheels are steered and driven in accordance with the detected output from the detection coils. A pair of detection coils are arranged to follow the movement of the wheels to be steered in such a manner that the detection coils are disposed away from each other at a predetermined distance from the guide cable when the A.G.V. runs a straight portion of a course, while the detection coils are positioned closer to the guide cable when the A.G.V. runs a curved portion. As a result, when the A.G.V. runs the straight portion, the sensitivity with respect to the deviation between the detection coils is kept low so that the carrier can run smoothly, when the A.G.V. runs a curved portion, the sensitivity with respect to the deviation between the detection coils is increased. Consequently, operating performance such as high speed operating performance and the minimum turning diameter can be improved.

摘要： A stable charge coupled device (CCD) imaging apparatus operable in multiple frame rates for displaying a signal having a low frame rate in a viewfinder (VF), and also a recorder built-in type imaging apparatus using the CCD imaging apparatus are presented. The imaging apparatus includes a drive pulse switching circuit for multiplying a CCD drive pulse other than a CCD read pulse by (n/2) (where n is an arbitrary integer) when the multi-frame rate is low, a frame memory for storing an output signal of the CCD of one frame right after pulse output. The signal is read at every (n/2) frames. The frame memory repeats to read out the stored signal in one frame (n/2) times. The imaging apparatus further includes a camera signal processing circuit for performing a camera process to an output signal of the frame memory, and a recorder unit for recording an output signal of the camera signal processing circuit at the frame rate of the set mode. As a result, even at a low frame rate, the apparatus displays a signal in the VF. And with a properly-selected value of n, the apparatus conducts a signal having various frame rate between a camera and the recorder at a common frame rate.

摘要： The present invention uses a single television camera (40), an optical system, and a plurality of optical paths comprising a plurality of mirrors (22), (23), and (26), and shutters (24) and (27) for blocking light. Object images from the optical paths are alternately selected in synchronization with the field scanning operation of the television camera (40) to be projected into the television camera (40) so that a final image is picked up in three dimensions. The imaging device (FIG. 2) used in the television camera (40) has two-dimensionally arranged photoelectric converting elements (42) and corresponding vertical transfer stages (43), and is designed so that signal charges accumulated in the two-dimensionally arranged photoelectric converting elements (42) are transferred simultaneously to the corresponding vertical transfer stages (43). The timing of selecting the object images for projection into the television camera (40) is approximately in synchronization with the timing of transferring the signal charges from the photoelectric converting elements (42) to the corresponding vertical transfer stages (43).

摘要： An image pickup apparatus operated in mode-1 in which signal-charge that is charged in a CCD imaging device is read out as the output signal of the CCD imaging device once in each field of progressive-scanning, or in mode-2 in which the signal-charge is read out once (viz. during one field) in every two fields of progressive-scanning. And the output signal of the CCD imaging device is written into a memory according to a progressive-scanning synchronizing signal during the intervals when the signal-charge is read out. Then the signal written in the memory is read out, in the mode-1, according to the progressive-scanning synchronizing signal, and, in the mode-2, in such a manner that odd lines are read out in each odd field and even lines are read out in each even field according to an interlaced-scanning synchronizing signal. The above structure enables the image pickup apparatus to have simple circuit, good performance, and to be usable for at least the two modes of the 525/60P mode and the 525/30P mode.

摘要： A digital processing color camera includes a matrix circuit for arithmetically processing digital R, G and B video signals, which have been sampled by a clock signal, to provide a digital brightness signal, a first digital color difference signal and a second digital color difference signal. Those signals are subsequently converted by associated digital-to-analog converters into an analog brightness signal, a first analog color difference signal and a second analog color difference signal. Both the brightness signal and the first color difference signal, are delayed a predetermined period of time by digital delay lines inserted between the matrix circuit and the digital-to-analog converter circuit.

摘要： An imaging apparatus requiring a large dynamic range captures an image including a moving image with an increased dynamic range without degrading resolution. In an imaging apparatus 100, an L/S separation unit 3 generates a long-signal and a short-signal based on a video signal output from an imaging unit 1, which includes an image sensor having a first group of pixels that accumulate charge for a first charge accumulation time and a second group of pixels that accumulate charge for a second charge accumulation time. A saturation detection unit 4 detects whether the long-signal is saturated. A saturated part of the long-signal is replaced with an interpolated long-signal, which is a signal having the same signal level as the long-signal obtained by interpolation using the short-signal. A selector unit 8 outputs the resulting long-signal as a corrected long signal. An L/S combining unit 9 sequentially switches the corrected long-signal and the corrected short-signal output from a multiplier to generate an output video signal. A drive unit 2 drives an imaging unit 1 in a manner that a center time of the first charge accumulation time and a center time of the second charge accumulation time coincide with each other.
