The present invention relates to a device for improving an image quality in real time. In particular, a device for automatically compensating an image of a security system comprises: an image compensation unit for inputting a digital signal outputted from an ADC according to a control signal to improve an image quality through the processes of improving an image, removing a noise and removing fog, etc., adjusting the correction degree by corresponding image quality control parameters predetermined in multiple modes to the modes and providing a DAC with the adjusted correction degree; an operation mode selection unit for outputting a selection signal to select, by a user, the correction degree of the image quality improved by the image compensation unit; and a control unit for inputting the selection signal outputted from the operation mode selection unit and controlling the ADC, DAC and the image compensation unit. According to the system and the method of the present invention, the quality of the image transmitted from a CCTV can be improved by adding the device of the present invention to an output end, etc. of the existing CCTV without replacing the CCTV camera with a CCTV camera having high specifications. Furthermore, by considering that the clearness of the monitored image can be inconsistently determined by people due to differences in personal tastes, vision status or color detection abilities, the device and the method allows a manager to select and operate the compensation degree according to the image quality status of a screen monitored by the manager so that the manager can select the image that the manager thinks as a clear image. Therefore, the reliability of the image compensation device can be improved. |
