Video camera apparatus

Abstract

The video camera apparatus and image sensing method are capable of obtaining a still image without blurring even when a moving object is picked up with use of a solid image sensor capable of progressive scanning. An electronic shutter of a CCD image sensor 23 capable of outputting an image sensing signal in a progressive scan mode is controlled by a timing signal generator 28, with the field cycle according to the standard television system used as a basic cycle, to cause the CCD image sensor 23 to output an image sensing signal in the progressive scan mode.

Description

TECHNICAL FIELD [0001] The present invention relates to a video camera apparatus and an image-sensing method in which images are picked up by a solid image sensor capable of outputting an image sensing signal in a progressive scan mode with use of an electronic shutter. BACKGROUND ART [0002] Conventionally, in a video camera apparatus according to a standard television system such as NTSC (National Television Systems Committee) or PAL (Phase Alternation by Line), an interlace-scanned image sensing signal is obtained from an image-sensing section and is outputted as a video signal according to a predetermined standard television system. Further, in a video cassette recorder (VCR) or a video tape recorder (VTR) integrated with a camera, which is a so-called camcorder, a solid image sensor performs image sensing operation synchronized with a vertical synchronization signal VD, as shown in FIG. 11, and image sensing charges are read out for every one field as a charge storing period, th...

Benefits of technology

"The present invention relates to a video camera apparatus and an image sensing method that can capture still images without blurring when a moving object is picked up using a solid image sensor that outputs image sensing signals in a progressive scan mode. The invention controls the electronic shutter of the solid image sensor to output the image sensing signals in the progressive scan mode at the field cycle of the standard television system used as the basic cycle. The image sensing signals can then be converted into interlace scan signals and recorded. The technical effect of this invention is that it allows for the capture of high-quality still images without blurring even when a moving object is picked up using a solid image sensor capable of progressive scanning."

Problems solved by technology

In case of dealing with a still image in the camcorder, since two fields of the interlace-scanned image sensing signal form an image corresponding to one frame, a time delay between fields causes deterioration of image quality.

A problem hence appears in that the image cannot be quite still.
