Abstract: This application discloses a photographing apparatus and method, and relates to the field of image processing. When a high-quality image in a low illumination environment is obtained, costs are reduced, a size is reduced, and product compatibility is improved. The method includes: controlling a light filtering unit to: transparently transmit visible light in incident light and block infrared light in the incident light in a first image exposure interval, transparently transmit the infrared light in the incident light in a first time period of a second image exposure interval, and block the incident light in a second time period of the second image exposure interval; performing, by using an image sensor to obtain a first image, and performing photoelectric imaging on a light ray to obtain a second image; and synthesizing the first image and the second image, to generate a first target image.

Abstract: Disclosed are a traffic signal recognition method, a traffic signal indication apparatus (100), and a terminal (200), which are applied to the field of intelligent driving. In addition to an existing visible light signal indication system in a traffic light pattern, the traffic signal indication apparatus (100) adds a near infrared light source (110, S). The vehicle-mounted terminal (200) determines, based on a collected near infrared light signal, traffic operation information indicated by the traffic signal indication apparatus (100). The near infrared light signal has stronger penetration force than a visible light signal. Therefore, traffic signal recognition accuracy can be improved.

Abstract: An embodiment of this application discloses an image capturing apparatus, including a rolling shutter image sensor, a wheel, and a driving apparatus. The wheel is located on a photosensitive side of the rolling shutter image sensor, and a light shielding part for blocking light and a light transmission part for transmitting light are disposed on the wheel. When the driving apparatus drives the wheel to rotate, the light transmission part on the wheel periodically transmits light, so that a plurality of rows of photosensitive units in the rolling shutter image sensor receive the transmitted light, and convert a light signal into an electric signal through optical-to-electrical conversion. In addition, the rolling shutter image sensor is combined with the wheel, to reduce costs of the image capturing apparatus.

Abstract: An optical path switching method is applied to a surveillance module. The method includes: determining a target magnification; and (i) when the target magnification is less than or equal to a maximum magnification of a camera, setting a magnification of the camera to the target magnification, determining that a reflection element is at a first location or in a first working state, and performing image capture by using the camera alone; or (ii) when the target magnification is greater than a maximum magnification of the camera, setting a magnification of the camera to a first magnification, determining that the reflection element is at a second location or in a second working state, and performing image capture by using both the camera and a teleconverter, where a product of the first magnification and a magnification of the teleconverter is the target magnification. The method increases a surveillance distance while reducing costs.
