Embodiment 1
[0046] like figure 2 As shown, it is a schematic flowchart of a method for taking photos when scanning questions provided by an embodiment of the present invention, and the method may include:
[0047] Step S201, after the designated terminal receives an instruction to scan the questions, call the camera of the designated terminal.
[0048] Generally, the interface of the question-scanning application program provides a designated button to start taking photos. When the user clicks this button (it can also be triggered by voice, fingerprint, gesture or physical button), it is equivalent to sending an instruction to execute the question-scanning.
[0049] Optionally, the process of invoking the camera of the specified terminal may include:
[0050] Obtain the number of rear cameras of the specified terminal;
[0051] If the specified terminal has only one rear camera, then select this camera as the preferred camera; if the specified terminal has more than two rear cameras, t...
Embodiment 2
[0072] like image 3 As shown, it is a schematic flowchart of a method for taking photos when scanning questions provided by an embodiment of the present invention, and the method may include:
[0073] Step S301, calling the camera of the designated terminal after the designated terminal receives the command to scan the questions;
[0074] Step S302, adjusting the photographing parameters of the camera according to a preset adjustment method, so as to reduce information not related to text recognition;
[0075] Step S303, after the specified terminal receives the instruction to take pictures, control the camera to take pictures according to the adjusted picture parameters, and use the pictures taken as the original pictures for text recognition during question scanning.
[0076] Wherein, step S301 is the same as step S201 in the first embodiment, and step S303 is the same as step S203 in the first embodiment. For details, please refer to the description in the first embodimen...
Embodiment 3
[0091] like Figure 4 As shown, it is a schematic block diagram of a device for taking photos when scanning questions provided by an embodiment of the present invention, and the device may include:
[0092] The calling module 401 is used to call the camera of the designated terminal after the designated terminal receives an instruction to perform scanning;
[0093] An adjustment module 402, configured to adjust the photographing parameters of the camera according to a preset adjustment method, so as to reduce information unrelated to text recognition;
[0094] The photographing module 403 is configured to control the camera to photograph photographs according to the adjusted photographing parameters after the designated terminal receives an instruction to perform photographing, and use the photographs obtained as original photographs for text recognition during question scanning ;
[0095] The adjustment module 402 includes:
[0096] The first adjustment unit 4021 is configur...
