Abstract: An image processing method and apparatus, and a shooting terminal, where the method includes acquiring a to-be-processed image that is shot but is not image-processed; extracting shooting characteristic information of the to-be-processed image; performing image processing on the to-be-processed image according to the shooting characteristic information. In this way, after acquiring a to-be-processed image that is shot, a shooting terminal uses shooting characteristic information of the to-be-processed image as a basis of adaptive processing of the image, and performs processing on each to-be-processed image according to shooting characteristic information of each to-be-processed image, so that the quality of an image that is obtained after being processed by the shooting terminal can be adaptively improved.

Abstract: A scene recognition method includes acquiring an image and sensor data corresponding to the image and determining, in accordance with the sensor data, whether a scene of the image is a non-high-dynamic range (HDR) scene. The method also includes extracting an image feature of the image when it is not determined whether the scene of the image is the non-HDR scene and determining, in accordance with the image feature, whether the scene of the image is an HDR scene.
Abstract translation: 场景识别方法包括获取与图像相对应的图像和传感器数据，并且根据传感器数据确定图像的场景是否是非高动态范围（HDR）场景。 该方法还包括在不确定图像的场景是否为非HDR场景时提取图像的图像特征，并且根据图像特征确定图像的场景是否是HDR场景。
