Self-adaptive chroma compensation illumination light source lamp for underwater camera

Abstract

The present invention discloses a luminaier for underwater shooting self-adaptive chrominance compensating illumination light source, and is characterzed by that in compressive lamp box a support is set, one side of upper portion of said support is equipped with an array plate LED light-emitting lamp, and its another side is equipped with a condenser, the lower portion in the interior of compressive lamp box has a control drive circuit, a compressive glass window is positioned at condenser position, and a scene ranging sensor is placed in the lower portion of interior of the compressive lamp box, and the control drive circuit is respectively connected with scene ranging sensor and array plate LED light-emitting lamp, in which the control drive circuit uses the microprocessor to respectively connect with scene ranging sensor circuit, chromatic ratio circuit and memory and uses the power amplification drive circuit to respectively connect with chromatic ratio circuit and array plate LEDlight-emitting lamp. The interior of microprocessor also has the control software for underwater shooting self-adaptive illumination light source.

Description

[0001] Technical Field The present invention belongs to the category of optical equipment, and in particular relates to camera lighting lamps and controls. Background technique [0002] Underwater photography is a commonly used technical means to explore rivers, ocean underwater geography, biology, physics, chemistry, mineral deposits, etc. Usually due to the chemical composition of water, especially seawater, optical refraction, reflection and other reasons, the quality of underwater photography is not ideal, and the main factors affecting the degradation of underwater photography quality are the following aspects. [0003] (1) Absorption: Since water absorbs light much more than air, the viewing distance is only about 1 / 1000 of that in air. Below the depth of 100 meters, it is basically a dark world. [0004] (2) Scattering: Due to the strong scattering of light by various particles in the water, the water appears hazy, and ...

Problems solved by technology

However, due to the strong scattering effect of sea water, the background scattered light also increases, which greatly reduces the contrast of the image, and the image is blurred like a layer of white fog.

[0013] Secondly, because sea water absorbs light of different wavelengths very unevenly, the images taken are all greenish, and the farther the distance, the worse

[0014] In addition, although the brightness of the laser is very high, it will produce very annoying interference speckle, which seriously affects the clarity of the image.

[0015] At the same time, the chromaticity compensation range of the camera device is small, and it can only be suitable for a certain distance

And when the distance changes, the compensation will fail
