Problems solved by technology

[0003] 1. The existing shooting system uses a single lens to match a single photosensitive chip. The wavelength of light that needs to be received by a single photosensitive chip is relatively wide. Therefore, the overall picture definition is not high, and the shooting effect is not good;
[0004] 2. The existing shooting system uses a single lens to match a single photosensitive chip, reflecting that the wavelengths of each color are not well restored on a single photosensitive chip, resulting in the phenomenon that the color of the shooting picture is not full enough;
[0005] 3. The existing shooting system uses a single lens to match a single photosensitive chip. In a low-light environment, some wavelengths of light waves cannot be used, resulting in a decrease in the overall light flux and unclear images.

Abstract

The invention discloses a multi-light shooting system, which comprises an optical lens, and a light splitting module capable of splitting light waves transmitted by the optical lens into a plurality of light waves with different wavelength ranges is arranged on the imaging side of the optical lens; the shooting system further comprises at least two photosensitive chips used for receiving the lightsignals split by the light splitting module. The shooting system further comprises an image processing module capable of integrating and outputting the light waves received by the photosensitive chips. The light splitting module is provided with a light splitting inclined plane, and the included angle a between the light splitting inclined plane and the horizontal direction is greater than or equal to 10 degrees and less than or equal to 60 degrees; the wavelength of the light wave split by the light splitting module is between 420 nanometers and 650 nanometers, or one part of the wavelengthis between 420 nanometers and 650 nanometers, and the other part of the wavelength is between 700 nanometers and 1100 nanometers. According to the invention, high definition of a shot image is realized, the image color reducibility is good, and clear imaging can be realized under low illumination.

Description

【Technical field】 [0001] The invention relates to an optical system, in particular to a multi-light shooting system. 【Background technique】 [0002] At present, monitoring and shooting systems are widely used in people's daily life. But present security monitoring, traffic monitoring system have following shortcoming: [0003] 1. The existing shooting system uses a single lens to match a single photosensitive chip. The wavelength of light that needs to be received by a single photosensitive chip is relatively wide. Therefore, the overall picture definition is not high, and the shooting effect is not good; [0004] 2. The existing shooting system uses a single lens to match a single photosensitive chip, reflecting that the wavelengths of each color are not well restored on a single photosensitive chip, resulting in the phenomenon that the color of the shooting picture is not full enough; [0005] 3. The existing shooting system uses a single lens to match a single photosens...
