Example Embodiment

[0032] The method of the present invention will be further described in detail below in conjunction with the drawings and the embodiments of the present invention.

[0033] A portrait photography optimization system based on automatic photometry, the system including

[0034] The first judgment unit judges whether the user triggers manual focus, and generates a first judgment result;

[0035] The second judgment unit detects the preview frame acquired by the camera, and judges whether a human face is detected,

[0036] Generate the second judgment result;

[0037] The third judgment unit judges whether a close-range portrait is being taken, and generates a third judgment result;

[0038] The light metering unit is used to control the camera to enter any one of three light metering modes: portrait metering mode, automatic metering mode, or manual metering mode according to the first judgment result, the second judgment result, and the third judgment result.

[0039] Specifically, after the...

Abstract

The invention belongs to the technical field of image processing, and particularly relates to a portrait photographing optimization system, method and device based on automatic photometry. The systemcomprises a first judgment unit for judging whether a user triggers manual focusing or not and generating a first judgment result; a second judgment unit which is used for detecting the preview frameacquired by the camera, judging whether a human face is detected or not and generating a second judgment result; a third judgment unit which is used for judging whether short-distance portrait photographing is carried out or not and generating a third judgment result; a photometry unit which is used for controlling the camera to enter any one of a portrait photometry mode, an automatic photometrymode and a manual photometry mode according to the first judgment result, the second judgment result and the third judgment result. When a user performs selfie, the user does not need to know the operation with high manual focusing requirement, and meanwhile, the user can take pictures which are highlighted by himself/herself and layered compared with central average photometry.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a portrait photography optimization system, method and device based on automatic light metering. Background technique [0002] The metering system of a digital camera generally measures the brightness of the light reflected from the subject, which is also called reflective metering. The light metering method can generally be divided into two ways: external light metering and internal light metering according to the different placement positions of the light metering elements. External light metering: In the external light metering mode, the optical path of the light metering element and the lens is independent. This metering method is widely used in head-up viewfinder lens shutter cameras, and it has sufficient sensitivity and accuracy. Single-lens reflex cameras generally do not use this metering method. Internal metering: This metering method is metering...
