FIELD: physics.
SUBSTANCE: invention relates to terminal devices (terminals) and more specifically to a photographing method, a photographing device and a mobile terminal in the field of terminals. Claimed mobile terminal for photographing comprises: a processor; and memory storing instructions which, when executed by the processor, instruct the mobile terminal: determine that the current photographing scene is a dark scene or a scene with a light source; enter night shooting mode; and capture the target image in night shooting mode by means thereof. At that, fixing of target image in night shooting mode is performed by means of displaying preview interface, wherein the preview interface displays a moon icon to indicate that the mobile terminal is currently in night shooting mode; receiving a photographing instruction when a preview interface is shown; and displaying the photographing interface in response to receiving the photographing instruction, wherein the photographing interface displays a progress indication indicating that the mobile terminal is performing processing to generate a target image, and displays an indication prompting the user to maintain the mobile terminal in a stable state, wherein processing uses a plurality of frames for synthesis of a high dynamic range image as a target image, and a plurality of frames is obtained based on the plurality of parameters, including the exposure duration, light sensitivity and the number of frames. First exposure duration, the first photosensitivity and the first number of frames are used for processing when the mobile terminal is in the hand-held state and the current photographing scene is defined as a dark scene. Second exposure duration, second photosensitivity and second number of frames are used for processing, when the mobile terminal is not in hand-held shooting state and the current photographing scene is determined as a dark scene, third exposure duration, third light sensitivity and third number of frames are used for processing, when the mobile terminal is in hand-held shooting state and the current photographing scene is determined as a scene with a light source, and the fourth exposure duration, the fourth photosensitivity and the fourth number of frames are used for processing when the mobile terminal is not in a hand-held state and the current photographing scene is determined as a scene with a light source. First exposure duration is shorter than the second exposure duration, the first photosensitivity is greater than the second photosensitivity, third exposure duration is shorter than the fourth exposure duration, and the third photosensitivity is greater than the fourth photosensitivity; and storing the target image.
EFFECT: improved photographic effect of the image.
