Digital scene-touching technique camera

Abstract

The invention relates to a digital scene-touching technique camera, which consists of a lens clamping seat and a scene-touching plate and is characterized in that: 1, the lens clamping seat can be connected with various photographic lenses rotatablely; 2, random multipoint light metering and random multipoint focusing can be achieved on the scene-touching plate through a mouse pointer or a touch-pen; 3, a suitable aperture is matched automatically according to a selected focal point to ensure that the focal point is in the range of the depth of scene; 4, one point is selected in a highlight area automatically as an upper initial point, one point is selected in a shadow area automatically as a lower initial point, and an exposure value is locked to perform average light metering in the areas; 5, the lens clamping seat can be connected with large and medium picture cameras and is used as a digital back; 6, the large picture camera is provided with a special belt cavity, and the lens clamping seat can perform parallel translation upwards, downwards, leftwards and rightwards to shoot digital slices; and 7, the lens clamping seat and the scene-touching plate are configured with standardparts, are matched with configuration combinations of an image sensor and the like automatically according to needs, and can be updated without changing a shell to achieve the aim of reducing the usecost.

Description

technical field [0001] The invention relates to a camera, in particular to a camera which can be connected with various lenses and supports average light metering and focus light metering. Background technique [0002] The camera is only 169 years old. Simply put, there are four periods of camera development: from the end of the 19th century to the beginning of the 20th century, photographers smeared photosensitive materials on the glass and took pictures on the spot. We call the first period of on-site coating, shooting and washing; In the 1950s, with the use of large-scale sheet cameras (8X10, 4X5) and simplified developing techniques, photos with rich layers and fine contrast were produced; after the 1950s, with the invention of 120, 135 cameras and color film and the Popularity has made photography enthusiasts all over the world. This is the third period of comprehensive development of film cameras; from the end of the 20th century to the beginning of the 21st century, ...

Problems solved by technology

[0006] 1. The lens holder and the touch panel are divided into two parts, which not only solves the problem of incompatibility of camera lens interfaces of various manufacturers at low cost, but also solves the heat dissipation problem of high-pixel image sensors, high-resolution image processors and Micr CPU;

Average light metering at any point can solve the problem of troublesome operation when metering parts other than the center
