Wide dynamic infrared image acquisition structure, acquisition device and display method

Abstract

The invention provides a wide dynamic infrared image acquisition structure, an acquisition device and a display method, and solves the technical problem that the luminous flux cannot meet the imagingrequirement under the existing hardware condition. The device comprises an outer fixing ring which is used for being fixed with a bearing structure of a corresponding lens in a lens sleeve through anouter ring and providing an access end point of a control signal and a power signal; an inner fixing ring which is used for being coaxially fixed with the lens through an inner ring, an outer ring which is movably embedded in the inner ring of the outer fixing ring, and the inner fixing ring is controlled to be intersected with the outer fixing ring in a coaxial line or axis coaxial point mode; and a lens which is used for collecting low light or infrared light in the field of view. More paraxial luminous flux intensively enters an optical signal acquisition channel of the lens in a time-sharing manner within a short time period through regular deflection, so that the optical sensor can obtain more framed related optical information of a distant scene in a view field, and the requirementsof contrast identification and imaging enhancement of different fields of field and different scenes in an ISP processing process are met.

Description

technical field [0001] The invention relates to the technical field of optical signal processing, in particular to a wide dynamic infrared image collection structure, a display device and a display method. Background technique [0002] In the prior art, the imaging quality is directly affected by the luminous flux, and the area size of the optical sensor at the focal plane is positively correlated with the imaging quality. However, the size of the optical sensor is limited by the structural density and manufacturing cost, and the image is only processed by the ISP (Image Signal Processor). The final image obtained by processing cannot satisfy the effective recognition of long-distance observation objects. Therefore, more luminous flux is required for the recognition of longer-distance scenes so that the optical sensor can obtain more optical information. In the process of low-light imaging or thermal imaging, the initial luminous flux is always limited, and the final image a...
