Electronic image stabilizer for video camera use

A compact electronic image stabilizer has been realized on the basis of: (1) scanning area selection of the imager, and (2) motion vector detection. The stabilization rate is 18 dB at 1 Hz. This system is suitable for compact video cameras, but the stabilization rate becomes poor at high frequency. Therefore, an advanced system was also designed. >

An Electronic Variable-Shutter System in Video Camera Use

Since 1981 when we marketed worlds first MOS color video camera,1) we have been continuously improving the performance of this line of video cameras. And in 1986 we have developed an MOS color video camera with high resolution, with high sensitivity, and without smear.2)

Ultra small video camera and a video camera system

Image data photographed by a video camera 20 is compressed by a compression and decompression circuit 5, the compressed image data is recorded in an incorporated type semiconductor memory 6 or disk-type memory 13 fixed in the video camera 20 and the recorded image data is transferred to an external recording device 23. Further, the external recording device 23 records the transferred image data in a data storage while it is being compressed. The video camera 20 receives, decompresses and converts into a television signal the compressed image data read by the external recording device 23 in a reproducing operation. A video camera system capable of recording and reproducing long hours of image data by using a video camera having an ultra small size comparable to that of an 8 mm video cassette can be realized by using such a construction.

A Solid State Color Video Camera with a Horizontal Readout MOS Imager

Since 1981 when we marketed worlds first MOS color video camera1), we have been continuously improving the performance of this line of video cameras in order to match the market needs year by year2). We recognize, however, the performance we have achieved is not satisfactory enough.

An Electronic Zoom Video Camera Using Imager Scanning Control

An electronic zoom system for video camera use has been developed. Zoom ratios were designed to be smoothly changed vertically and horizontally by controlling imager scanning and line memory scanning, respectively. Two CMOS digital LSIs, a scanning pulse generator, and a signal zoom processor were developed for this electronic zoom system. >

A multimedia color camera providing multi-format digital images

A multimedia-use color camera has been developed which provides not only an analog video output but also digital images of various formats such as a CIF (common intermediate format) YC video image and an RGB (red, green, blue) still image with square pixels. In order to generate many image formats flexibly, the following technologies have been developed: (1) programmable CCD (charge coupled device) scanning, (2) programmable interpolation, and (3) programmable color matrix. >

A video pre/post-processing LSI for video capture

A video processing LSI which converts video signals to digital YUV signals in various image formats was successfully developed for a video capture system. This LSI is suitable for PC cameras, camera/recorders and PC video capture boards.

A network MPEG camera

A network MPEG camera which can be directly connected to a network for real-time digital video transmission has been developed. The camera works under TCP/IP protocol, and accepts remote control commands from PCs. The command set of the camera includes record/pause command, mode change command, zoom control command, bit rate control command, and so on. The bit rate of MPEG video bit stream can be changed even in the data transmitting and encoding period.

A Digital Video Camera With An Arbitrary Aspect Ratio

A novel video camera with an arbitrary aspect ratio was developed using newly developed digital signal processing VLSIs. Programmable VLSI circuits are adaptively controlled by a microcomputer. With the arbitrary aspect ratio of this digital camera, the proposed wide-screen CCD (charge-coupled device) imager could compete with conventional 3:4 imagers. >

A 0.8 mu m CMOS digital signal processor for a video camera

A digital signal processor has been developed for a video camera by using a 0.8- mu m CMOS process. This LSI includes almost all the functions of a video camera. It also integrates a circuit for extending the dynamic range and a three-line color processing circuit to realize true-to-life color reproduction. Using this LSI, a compact and lightweight video camera with high picture quality has been realized. >
