Title:
SPECTRAL CURVE ACQUIRING METHOD, ELECTRONIC DEVICE, AND CHIP
Document Type and Number:
WIPO Patent Application WO/2020/244619
Kind Code:
A1
Abstract:
Provided in the present application are a spectral curve acquiring method, an electronic device, and a chip. The electronic device receives a photographing request inputted by a user requesting to photograph a set of images, controls the order of exposure of supplementary lights in a supplementary lighting device on the basis of the photographing request, and produces a set of images on the basis of the order of exposure, the set of images comprising an image for which lighting is provided simultaneously by the different supplementary lights and the ambient light and an image for which lighting is provided solely by the ambient light. Then, the electronic device obtains a spectral curve of a target object on the basis of the images. In the process, with the supplementary lights providing lights of different wavelengths, images of different wave bands of the target object are produced, thus acquiring the spectral curve of the target object, obviating the need for a dedicated spectrometer, and making costs inexpensive. Moreover, this can be provided to general users for use in daily life. In addition, the process of acquiring the spectral curve does not alter the architecture of the electronic device for normal photographing.
