Photographic equipment for light source colorimetric measurement

Abstract

The invention relates to photographic equipment for measuring the chromaticity of a light source. The photographic equipment comprises a fixed machine body, a lighting lens, an optical filter replacing mechanism, a CCD (Charge-Coupled Device) image sensor and a displacement focusing mechanism, wherein the lighting lens and the optical filter replacing mechanism are fixedly arranged on the fixed machine body; the optical filter replacing mechanism is positioned on the rear side of the lighting lens, so that a work optical filter on the optical filter replacing mechanism is positioned on a light path lighted by the lighting lens; the CCD image sensor is fixedly arranged on the displacement focusing mechanism, is positioned on the rear side of the work optical filter on the optical filter replacing mechanism and corresponds to the work optical filter; and a motion track of the displacement focusing mechanism is parallel to the lighting light path, so that the CCD image sensor is always positioned on the light path filtered by the work optical filter in the motion process of the displacement focusing mechanism. Therefore, the acquired image data can be acquired and compared by a data acquiring and comparing system, and further real color of the an image can be restored.

Description

technical field [0001] The invention relates to an image acquisition equipment technical device, in particular to a photographic equipment used for light source chromaticity measurement. Background technique [0002] At present, the existing image processing equipment, such as cameras, cannot illuminate the true color of the image. Any lens will deviate when picking up light, which will cause the color of the photo to be different from the real color. The existing image processing None of the devices have the ability to restore the true color of the image. [0003] Its structure of existing camera equipment all is that the lens is a retractable structure to adjust the focal length, and the structure of the CCD sensor (formally called as a charge coupling device) for collecting images at the rear is fixed, and there is no filter group in it. This kind of traditional image acquisition equipment is only used for taking pictures. For the application of restoring the true color ...

[0002] At present, the existing image processing equipment, such as cameras, cannot illuminate the true color of the image. Any lens will deviate when picking up light, which will cause the color of the photo to be different from the real color. The existing image processing The equipment does not have the function of restoring the true color of the image

[0003] Its structure of existing photographic equipment all is that the lens is a retractable structure to adjust the focal length, and the structure of the CCD sensor (formally called as a charge coupling device) for collecting images at the rear is fixed, and there is no filter group in it. This kind of traditional image acquisition equipment is only used for taking pictures. For the application of restoring the true color of the image, for example, in the detection of LED display screen products, the existing image processing equipment is not competent
