Abstract: A method is applied to an electronic device including a color camera and a monochrome camera, and the color camera and the monochrome camera are disposed in parallel on the electronic device, includes: obtaining a to-be-processed color image obtained after the color camera photographs a target scenario, and extracting a first luminance component of the to-be-processed color image; obtaining a monochrome image obtained after the monochrome camera collects the target scenario at the same moment, and extracting a second luminance component of the monochrome image; performing registration on the first luminance component and the second luminance component by using a preset algorithm, to generate a third luminance component; extracting a chrominance component of the to-be-processed color image based on the third luminance component; and compositing a color output image based on the extracted chrominance component of the to-be-processed color image and the third luminance component.

Abstract: Embodiments provide a method and a terminal device for filtering objects. By using the technical solutions provided by the embodiments, the terminal device can display filtered objects, and problems in the prior art that a long time is needed to retrieve subsequent objects and that errors easily occur if the terminal device needs to display a lot of objects can be avoided, thereby effectively increasing the efficiency and reliability of displaying objects.
