Embodiment 1

[0056] The electronic device is a PAD, an apple is placed on the PAD, the apple is the object to be photographed, the PAD is an environment image, and the apple and the PAD form a first image. The PAD has an image acquisition unit, the image acquisition unit is located above the PAD, and can shoot images directly above the PAD. The PAD is connected with the image acquisition unit by wire.

[0057] The electronic device first acquires the first image information, where the first image information includes the environment image information and the object image information.

[0058] The central average metering method is used for brightness analysis, and the overall metering value of the camera is organically separated. The metering data in the central part accounts for the vast majority of the proportion, while the metering data outside the center of the screen is a small proportion to assist in metering. effect. After weighting and averaging the ratios of the values ​​in thes...

Embodiment 2

[0065] The electronic device is a PAD, a water cup is placed on the PAD, the water cup is the object to be photographed, the PAD is an environment image, and the water cup and the PAD form a first image. The PAD has an image acquisition unit, the image acquisition unit is located above the PAD, and can shoot images directly above the PAD. The PAD is wirelessly connected with the image acquisition unit.

[0066] The electronic device first acquires the first image information, where the first image information includes the environment image information and the object image information.

[0067] The brightness analysis is carried out by using the central portion photometry method, and the photometry is performed on a central area of ​​the screen, and the photometry range is about 3% to 12%, and a brightness analysis result is obtained.

[0068] In this embodiment, the difference between the brightness value of the first point in the object image corresponding to the object imag...

Embodiment 3

[0075] The electronic device is a PAD, a book is placed on the PAD, the book is the subject of shooting, the PAD is an environment image, and the book and the PAD form a first image. The PAD has an image acquisition unit, the image acquisition unit is located obliquely above the PAD, and can shoot images downwardly on the obliquely above the PAD. The PAD is connected with the image acquisition unit by wire.

[0076] The electronic device first acquires the first image information, where the first image information includes the environment image information and the object image information.

[0077] Spot metering is used for brightness analysis, and a very small area in the center of the viewing window is used as the exposure reference point. The metering area is 2%, and the shooting unit uses the light measured in this narrow area as the exposure basis. Obtain a brightness analysis result.

[0078] In this embodiment, the difference between the brightness value of the first ...

Abstract

The invention discloses a brightness adjustment method used for improving shooting quality. The method includes: acquiring first image information including environmental image information and object image information of at least one shooting object; performing brightness analysis on the first image information to generate a brightness analysis result; judging whether a brightness value of an environmental image corresponding to the environmental image information is required to be adjusted or not according to preset conditions and the brightness analysis result; if yes, adjusting the brightness value of the environmental image corresponding to the environmental image information. The invention further discloses electronic equipment used for implementing the method.

Description

technical field [0001] The invention relates to the field of computers and embedded devices, in particular to a brightness adjustment method and electronic equipment. Background technique [0002] When an object is placed on the display screen, when the object is photographed, it may be affected by the self-luminescence of the screen, thereby interfering with the quality of the obtained image of the object, which may make the captured photos not clear enough and reduce the probability of the object being recognized. Contents of the invention [0003] Embodiments of the present invention provide a brightness adjustment method and an electronic device, which are used to solve the technical problem that the brightness cannot be adjusted during shooting in the prior art, and achieve the technical effect of improving the shooting quality. [0004] A brightness adjustment method, applied to an electronic device, the electronic device has a display screen, the electronic device i...
