first embodiment

Referring to FIG. 1 , it shows a flow chart of a photographing method according to a first embodiment of the present invention. The method is applied to a mobile terminal with a curved screen, and may specifically include the following steps:

Step 101, when a mobile terminal user holds the mobile terminal with one hand, identify the holding mode.

Different from the traditional screen, which only has a flat feature, a curved screen refers to a screen with a certain curvature. For example, the left and right sides of the screen may be curved to a certain degree. In the embodiment of the present invention, the mobile terminal may be a terminal device such as a mobile phone and a tablet computer with a curved screen and capable of taking pictures, and the present invention does not limit the specific type of the mobile terminal.

In the embodiment of the present invention, the holding mode may include a left-handed mode and a right-handed mode, that is, the mobile terminal user may hold the mobile terminal with the left hand or the right hand, and perform a photographing operation.

In a specific implementation, when the mobile terminal user holds the mobile terminal with one hand, the holding mode can be identified by determining the specific position where the mobile terminal user's thumb is placed on the screen of the mobile terminal, for example, when the mobile terminal user's thumb is placed When the position is on the right side of the mobile terminal screen, it can be determined that the current holding mode is the right-handed mode. Correspondingly, when the mobile terminal user's thumb is placed on the left side of the mobile terminal screen, the current holding mode can be determined to be the left hand model. Those skilled in the art can identify the grip mode in different ways according to actual needs. For example, by comparing the left and right sides of the screen of the mobile terminal with the number of contact positions of the mobile terminal user's fingers, when the left side of the screen of the mobile terminal When the number of contact positions with the fingers of the mobile terminal user is more than that on the right side, it can be identified as a right-handed mode, otherwise it is a left-handed mode, which is not specifically limited in the present invention.

Step 102, based on the grip pattern, determine a target operation area on the curved screen of the mobile terminal.

In the embodiment of the present invention, different gripping modes may correspond to different target operation areas, that is, when the mobile terminal user holds the mobile terminal with the left hand or the right hand respectively, the finger of the left hand or the right hand is on the curved screen of the mobile terminal. Placement is different.

In a specific implementation, the target operation area may be determined only according to the holding position of the mobile terminal user's thumb, or may be determined according to the holding positions of all fingers of the mobile terminal user.

Step 103, receiving a press operation of the mobile terminal user in the target operation area.

Usually, the mobile terminal user can issue a photographing instruction by pressing the screen of the mobile terminal. Therefore, when the mobile terminal user performs a pressing operation in the target operation area, the mobile terminal can receive the corresponding photographing instruction by sensing a corresponding pressure value.

In a specific implementation, due to the difference in the target operation area, the press operation received by the mobile terminal may also be different. It is only the pressing operation triggered by the placement position of the corresponding thumb; and when the target operation area is determined according to the holding position of all fingers of the mobile terminal user, the corresponding pressing operation can be triggered by the placement position of each finger. Triggered press action.

Step 104, determine an operating parameter based on the pressing operation.

In the embodiment of the present invention, when the mobile terminal receives the corresponding pressing operation in the determined target operation area, it can be considered that the user of the mobile terminal has issued a corresponding photographing instruction, so that corresponding operating parameters can be determined for the photographing instruction, For example, focal length, exposure value, camera mode, etc.

Step 105, when the operation parameter satisfies the preset triggering condition for photographing, trigger the photographing operation to generate a photograph.

In the embodiment of the present invention, the preset triggering condition for photographing may be judging whether the pressing position of the thumb or all fingers of the mobile terminal user is within the target operation area, or judging whether the pressing time of the mobile terminal user is longer than the preset time threshold, etc.

When the preset photo-taking trigger conditions are all satisfied, the photo-taking operation of the mobile terminal may be triggered to generate a photo.

In the embodiment of the present invention, when a user holds a mobile terminal with a curved screen with one hand, the user can recognize the holding mode and determine different target operation areas according to different holding modes, so that when receiving the mobile terminal user's After the pressing operation in the target operation area, the operating parameters are determined, so that when the preset triggering conditions for photographing are met, the photographing operation is triggered and a photograph is generated, which solves the problem of photographing due to hand shaking of the mobile terminal user in the existing one-handed photographing process.
