Abstract: This application provides an image processing method and an image collection device. A haze intensity of a first image is calculated. When the haze intensity of the first image is greater than a first threshold, control information is sent, where the control information is used to control a haze penetration optical component to move into a lens. Because the haze penetration optical component can improve quality of optical imaging, the lens into which the haze penetration optical component is moved has a function of optical haze penetration. It can be learned that, when the haze intensity of the first image is greater than the first threshold, the function of the optical haze penetration is enabled, so as to improve quality of an image obtained in a haze environment.

Abstract: A method applied to a camera that includes a visible light sensor, a phase sensor, and a processor. The visible light sensor collects a visible light image of a shooting scene. The phase sensor collects a phase image of the shooting scene. The processor obtains depth information based on the phase image, and superimposes the depth information on the visible light image to obtain a depth image. Optionally, the camera may also include an infrared illuminator that may be turned on when a scene illumination is insufficient to increase an accuracy of the depth information.

Abstract: An image photographing apparatus includes an image sensor and a processor. The image sensor is configured to photograph at least one image of an object. The processor is configured to: obtain an image of the object under a preset light source based on the at least one image; for the image of the object under the preset light source, calculate a difference between sub-images of filter points at same corresponding positions in any two filter arrays in a first filter array set, to obtain a plurality of narrowband spectrum responses of the first filter array set; and obtain spectrum information of the object in the first filter array set based on the plurality of narrowband spectrum responses.
