20140125859 | AUTOFOCUS CAMERA SYSTEM AND CONTROL METHOD THEREOF - Disclosed is an autofocus camera system and a control method thereof. A CCTV camera system which includes a main processor installed in a CCTV, a memory unit connected with the main processor, an input unit, a CCD camera, a video processing unit, a focus lens, and a zoom lens is provided. The CCTV camera system is designed to input and output control instructions through RS-485 communication and is controlled by a focus motor driver and a zoom motor driver which are connected to the main processor in which a focus motor and a zoom motor are comprised of stepping motors. | 05-08-2014 |
20130057711 | BINARY CDMA IMAGE-TRANSCEIVING SYSTEM DIRECTLY CONNECTED TO AN IMAGE CAPTURE DEVICE - A binary CDMA image transmission and receiving system directed connected to an image capturing device includes an image transmission unit including: an image capturing device comprising a CCD/CMOS camera module and configured to output a captured digital image signal; an image pre-treatment processing unit configured to process a digital image signal output from the image capturing device to be vivid; a digital image processing unit configured to convert the image signal into a compressible signal; a transmission side A/V codec configured to compress an image and a voice of an output image signal; a transmission side host processor configured to perform a binary CDMA function, a transmission side binary CDMA baseband processor; and an RF transmission unit, and an image receiving unit including: an RF receiving unit configured to receive the transmitted RF signal; a receiver side binary CDMA baseband processor configured to receive and decode the received RF signal; a receiver side host processor; a receiver side A/V codec configured to restore the image and the voice; and an image post-treatment unit configured to output the image signal. The binary CDMA image transmission and receiving system may increase a resolution of an image through a digital processing method, not an analog method, may improve security by being capable of encoding a transmission data, may have an excellent frequency efficiency, may enable a remote distance communication superior to a short range wireless communication, and may enable a low power high speed transmission. | 03-07-2013 |
