Abstract: Embodiments of this application provide an electronic device and a picture processing method. The electronic device includes a rear cover, a front-facing camera, a rear-facing camera, and a light reflective apparatus. The light reflective apparatus may be switched between a usage state and an idle state. The picture processing method includes: controlling the light reflective apparatus to switch from the idle state to the usage state, so that the rear-facing camera captures a picture reflected by the light reflective apparatus; separately obtaining a picture captured by the front-facing camera and a picture captured by the rear-facing camera; processing the picture captured by the rear-facing camera; and fusing the picture captured by the front-facing camera and a picture obtained by processing the picture captured by the rear-facing camera. In this application, a field of view of a picture taken by the front-facing camera can be increased with relatively low costs.

Abstract: This application provides a dynamic vision sensor. The sensor converts an optical signal into an electrical signal by using a photoelectric conversion unit, to generate a photovoltage; performs second-order difference on the photovoltage by using a second-order differential circuit; and generates a second-order event signal based on a result of second-order difference. A camera including the sensor can generate an image based on the second-order event signal, where the image represents a change of a light change speed.

Abstract: An image rendering method and apparatus where the method includes recognizing a target area from a to-be-rendered image, setting a virtual light source for the target area, and performing rendering on the target area using the virtual light source. When rendering is performed on the to-be-rendered image, the rendering performed on the to-be-rendered image is implemented using the virtual light source. The virtual light source plays a rendering action only on the target area corresponding to the virtual light source, and does not affect another part of the to-be-rendered image, and therefore an image effect of the to-be-rendered image may be relatively good.
