Embodiment Construction

[0029] Throughout the drawings, the same reference numerals refer to the same parts, concepts and / or elements. Therefore, unless expressly stated otherwise, what is said about a reference number in one figure also applies to the same reference number in the other figures.

[0030] figure 1 A flowchart of a method 100 according to the present disclosure is schematically shown. It should be noted that not all depicted components are required for all implementations of the method. The method aims at determining the settings of a system comprising a camera and at least one artificial lighting device.

[0031] The method comprises a step 110 of obtaining first pre-image data from a scene with a camera using predetermined camera settings under ambient light conditions. Here, the scene refers to the field of view of the camera sensor. The first pre-image data may include image data acquired from the entire scene or a part of the scene. Here, "whole scene" refers to the full fiel...

Abstract

The present disclosure relates to a software implemented method adapted for a camera and artificial lighting system for determining atleast one artificial lighting device setting and / or camera setting. The method comprises obtaining first pre-image data (110) relating to at least part of a scene using said camera having a predetermined pre-image camera setting, wherein the first pre-image data is obtained in ambient light, obtaining second pre-image data (120) relating to at least part of the scene using said camera having the predetermined pre-image camera setting, wherein the second pre-image data is obtained from the scene being lightened with the artificial light, receiving (130) user information relating to one or more desired optical characteristics of at least part of an image to be captured using said camera, and determining (140) the artificial lighting setting and / or a camera setting for an image to be captured using said camera based on said obtained first pre-image data, said obtained second pre-image data and said received information relating to the desired or pre-set optical characteristics of at least part of the image to be captured.

Description

technical field [0001] The present disclosure relates to a method for acquiring visual data of a scene and determining settings of a camera and at least one artificial lighting device. Background technique [0002] Historically, in photography, the main use of artificial lighting devices such as flash units has been to capture images in low ambient light conditions. Artificial lighting can also be used to alter the optical properties of captured images. In order to capture an image with certain desired optical properties (eg, the relationship between exposure from ambient light and exposure from artificial light), specific settings are obtained for the camera and lighting device(s). These settings are, for example, ISO settings, aperture settings and exposure time settings for the camera and intensity, duration and color temperature settings for the lighting device(s). Some DSLR cameras allow the user to input a desired exposure compensation, which underexposes or overexpo...
