The storage time of temporal image.After image storage, above-mentioned electronic equipment can stab storage time corresponding with the image
Stored.
Step 404, calculates the second difference of storage time and the acquisition time with temporal image, and using the second difference as
The storage delay time.
In the present embodiment, above-mentioned electronic equipment can be with the storage time obtained in calculation procedure 403 and knowledge in step 401
Second difference of other acquisition time, and using above-mentioned second difference as the above-mentioned storage delay time with temporal image, it is above-mentioned
The storage delay time can determine that image has been stored for above-mentioned electronic equipment, from the collection image to the delay for storing the image
Time.
Step 405, stores the storage delay time, and mesh is determined with the storage time using storage delay time and target image
The acquisition time of logo image.
In the present embodiment, above-mentioned electronic equipment can be stored the storage delay time calculated in step 404, with
The acquisition time of above-mentioned target image is determined using the storage time of above-mentioned storage delay time and target image.Above-mentioned electronics sets
The standby storage time that can first obtain above-mentioned target image, afterwards, is subtracted above-mentioned using the storage time of above-mentioned target image
The storage delay time, using acquired results as above-mentioned target image acquisition time.
Step 406, in response to determining that band temporal image is not stored, storage tape temporal image.
In the present embodiment, if determine in step 402 it is above-mentioned band temporal image do not store, can by above-mentioned band when
Between image stored.
Step 407, is shown with temporal image by what is stored on the display screen for show temporal information, identification display
Second time of screen display, and using the second time as the second output time.
In the present embodiment, while above-mentioned band temporal image is stored, the band that above-mentioned electronic equipment will can be stored
Temporal image is shown on the display screen for show temporal information, and the time of above-mentioned display screen is recognized while display
The image of viewing area, and the second time that will identify that is used as the second output time.Above-mentioned second output time can be upper
