Background
Macro photography is one of the popular photographing modes at present, because the macro photography can magnify the small details of the photographed object and photograph more microscopic objects even objects invisible to human eyes, so that the macro photography has strong attraction and is increasingly applied to electronic products. However, because the photographing distance of the macro photographing is short, the photographing range is narrow, and the visual field range is small, the picture definition is affected by slight movement compared with the ordinary photographing. We find that the instant clear moment actually appears in the focusing process of the macro/micro photographing, but the clear moment is too quick and difficult to grasp due to the short photographing distance, and even if the clear focusing point is reached, the shaking is caused due to the fact that a photographing command needs to be operated, and the like, so that a user misses a clear image again. In addition, the portable terminal device often does not have fixed conditions for professional camera devices such as a tripod, and for a common photographing mode, even if a user sees that a photographed object is clear in a photographing frame, and clicks a photographing button with a finger or uses voice to photograph, the mode of clicking with the finger or voice may bring about small movement of the handheld device, which is not beneficial to photographing clear pictures. Therefore, for macro photography, even though the terminal device can increase the focusing speed, the shooting button is pointed by a hand or the shooting is performed faster by voice, which is not beneficial to taking clear pictures.

The preset definition threshold is an empirical threshold obtained from the previous definitions of a plurality of photographs. When the definition of the target photographic object on the photographic interface of the photographic terminal is greater than or equal to a preset definition threshold value, the target photographic object forms a clear picture on the photographic interface of the photographic terminal at the moment, and a picture with higher definition can be photographed by photographing at the moment. The sharpness of the photograph can be expressed in, but is not limited to, the gray value of the photograph. In addition, the preset definition threshold set by the user can also be a numerical value with lower definition, and can be set according to actual needs. And when the preset definition threshold is lower, the photographing terminal is equivalently used for continuous photographing operation.
