Problems solved by technology

At present, the mainstream sensors of cameras are Charge Coupled Device (CCD) and Complementary Metal Oxide Semiconductor (CMOS). Although it has been decades, the description ability (tolerance) of the two for complex light environments is still difficult to meet the needs of a large number of photographers. Higher requirements, a small number of high-end cameras use a special algorithm to stack multiple images with different exposures to improve, named HDR (High-Dynamic Range) technology, but this t...

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Please refer to Figure 1-Figure 6 , in an embodiment of the present invention, the mirrorless built-in HDR filter includes: a filter body 1; the filter body 1 is in a square shape;

[0027] The filter body 1 is provided with a square filter frame, and the filter body 1 can be manufactured in the following ways: 1. In the traditional silver halide color-changing glass, components such as silver halide and sensitizer are mixed in the glass manufacturing process; 2. The new photochromic glass is coated with a photosensitive magnetron sputtering film on the surface of the optical glass.

[0028] The working principle of the mirrorless built-in HDR filter provided by the present invention is as follows:

[0029] The first step: first match the filter body 1 with a suitable filter frame 5, and place the filter body 1 in the photographic equipment bo...

Abstract

The invention provides a micro single camera built-in HDR filter and photographic equipment adopting the same. The micro-single camera built-in HDR filter and the photographic equipment adopting the same comprise a filter body, the filter body is in a square shape. According to the micro-single camera built-in HDR filter and the photographic equipment adopting the filter, accurate local dimming can be carried out on complex ambient light; therefore, the high-dynamic-range image is obtained, the use is convenient, the photographing requirements under different light intensities are met, and thefilter needs to be set with different photosensitivities to correspond to different illumination environments such as sunny days, cloudy days and evening so as to meet various requirements of users.Approximately, the dimming gear number under the standard light can be used as a dimensionless unit for a user to accurately select, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a mirrorless built-in HDR filter and photographic equipment using the filter. Background technique [0002] Photochromic glass can be made by mixing silver halide sensitizer, copper ion sensitizer and CdO in the specific link of optical glass melting to make photochromic glass. At present, it is also possible to coat photosensitive film on the optical glass substrate. New technology to achieve photochromism. The exposed part of the special glass becomes darker, and the degree of darkening increases nonlinearly with the increase of light intensity, and the unexposed part is not affected. [0003] A camera is a device that uses optical principles to record images. The camera was originally invented for film and TV program production, but it has become popular now. Just like a camera, early cameras needed to use negatives for recording, but now digital cameras The invention of...
