A camera having a condensing filter is provided to increase a peripheral light rate and to enhance performance thereof by forming curvature around a circle of the condensing filter. A camera having a condensing filter includes a CCD(10), lenses(12,13,14), and a filter(21). The CCD(Charge Coupled Device) is formed to convert light to an electrical signal. The lenses are formed to concentrate the light on the CCD. The filter is installed between the CCD and the lenses in order to shield infrared elements. The filter is composed of a condensing filter having curvature formed around a circle in order to condense peripheral light. The condensing filter is formed to increase a peripheral light rate by changing an angle of the incident light.
