Abstract: 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.

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.

Abstract: 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.

Abstract: It is an object of this invention to correct a receiving error of a data stream in a set-top box when a software program is distributed by using data broadcasting. A base station converts a software program into a data stream of DSM-CC data carousel type, divides the data stream into transport packets of MPEG-2 type, and distributes the software program to the set-top box via a communications satellite. If the set-top box detects any receiving error of the data stream, it requests the base station to resend the transport packet which has not been properly received. The base station then resends the requested transport packet to the set-top box via a public circuit.

Abstract: 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.

Abstract: 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).

Abstract: 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.

Abstract: A color television camera of the phase-split type is disclosed wherein an index signal derived by horizontally scanning an index-generating section, produced at the beginning or end portion of vertical scan for an image pickup tube, is converted to a low-frequency signal by a frequency converter so that a low-frequency index signal in at least one horizontal scan period is written into a memory circuit, and the low-frequency index signal is read out for each horizontal scan to produce a standard color television signal from two color-difference signals. The two color-difference signals are derived by processing a modulated color signal, which has been space-modulated by a stripe filter disposed in front of the image pickup tube, and a low-frequency signal or a brightness signal derived from the image pickup tube.
