The invention discloses a device for testing colors of a colored CCD chip. The device mainly solves the problem that an existing testing device can not accurately judge color quality of the colored CCD chip. The device comprises a xenon lamp light source, a monochrometer, an attenuator, an integrating sphere, a dark room, a Dewar bottle temperature control chamber, a drive control circuit and an upper computer. A colored CCD chip to be tested is placed in the Dewar bottle temperature control chamber and is connected with the drive control circuit. The monochrometer generates monochrome light and three-primary color light through irradiation of the xenon lamp light source and parameter adjustment, after the monochrome light and three-primary color light are converted to uniform face array light through the integrating sphere and the dark room, the light irradiates the colored CCD chip to be tested, and rgb brightness values of an image are obtained through the drive control circuit and the upper computer. The image is transferred to an L*a*b* space from an rgb space, and color quality of the colored CCD chip to be tested is judged according to the magnitude of the Euclidean distance between a point to be tested and a standard point in the L*a*b* space. The device has the advantages of being high in adaptability and stability, accurate in measurement of color brightness values, and capable of being used for quality selection of colored CCD chips.
