The first, described second view data includes: at least one view data that described electronic equipment is obtained in the first preset time period before obtaining described second instruction.
For example, the first preset time period for example: 1min, 2min etc., wherein it is possible to by electronic equipment default setting, it is also possible to manually being arranged by the user of electronic equipment, the embodiment of the present invention is not restricted.
Assume at 14:00, electronic equipment detects that controlling electronic equipment is in the control instruction of opening, electronic equipment responds this control instruction and enters opening, electronic equipment produces the first instruction simultaneously, start automatic recording the first view data, electronic equipment detects the second instruction at 14:15, in this case, the second acquired view data is the view data collected before 14:15, such as: 14:14～14:15, at least one view data between 14:10～14:15 etc., certainly, above time point and time period are as just citing, the embodiment of the present invention is not restricted.
The program is often applied to image acquisition process, such as: user wishes to gather current image date at 14:14, however, it was found that mobile phone is the most at one's side, or mobile phone is not in image acquisition state, or handset response duration is longer etc., thus cause electronic equipment to obtain the second instruction and can there is a time delay, although that is to say that likely user is that 14:15 just produces the second instruction, but user wishes that gather is the view data of 14:14, in prior art, due to be can only acquisition testing to second instruction after view data, so may result in acquired image data and existing delayed, and in the embodiment of the present invention, then can collect the desired view data gathered of user accurately.
The second, described second view data includes: at least one view data that described electronic equipment is obtained in the first preset time period before obtaining described second instruction, and, at least one view data that described electronic equipment is obtained in the second preset time period after obtaining described second instruction.
For example, first preset time period is for example: 1min, 2min etc., second preset time period is for example: 2min, 5min etc., wherein, the first preset time period and the second preset time period the most both can be set by system default, it is also possible to manually set by user, and, second preset time period can not regular time section, but based on when obtaining the second view data, the operation of user and determine.
Assume at 14:00, electronic equipment detects that controlling electronic equipment is in the control instruction of opening, electronic equipment responds this control instruction and enters opening, electronic equipment produces the first instruction simultaneously, start automatic recording the first view data, electronic equipment detects the second instruction at 14:15, in this case, the second acquired view data had both comprised the view data before 14:15, also the view data after 14:15 is comprised, such as: the view data between 14:10～14:20, view data between 14:12～14:17 etc., certainly above time point and time period are also as just citing, the embodiment of the present invention is not restricted.
During the program is often applied to continuous image shooting or video acquisition, such as: user wishes continuous shooting view data at 14:14, then can there is a time delay owing to electronic equipment obtains the second instruction, the second instruction may be just obtained at 14:15, so in this case, in addition to needing to obtain the view data in the second preset time period after the second instruction, in addition it is also necessary to obtain the view data in the first preset time period before the second instruction.Based on the program, it is possible to preventing owing to acquisition the second instruction exists time delay, the second view data gathered caused is not accurate enough.
As a kind of optional embodiment, in order to save the memory space of electronic equipment, based on step S104 response the second instruction, intercepting after obtaining the second view data from described first view data, described method also includes: delete the view data that described first memory space is preserved.
