Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the invention discloses a kind of image processing method and terminal, can photo content be enriched, be described in detail respectively below.
In the embodiment of the present invention, terminal can comprise the smart machine arbitrarily with shoot function, wherein, smart machine includes but not limited to: mobile phone, panel computer, electronic reader, remote controller, personal computer (Personal Computer, PC), notebook computer, mobile unit, Web TV, wearable device etc. are configured with the smart machine of filming apparatus, in addition, in the embodiment of the present invention, terminal can be the device that camera or video camera etc. can carry out taking.
Refer to Fig. 1, Fig. 1 is the schematic flow sheet of a kind of image processing method disclosed in the embodiment of the present invention.As shown in Figure 1, the method can comprise the following steps:
S101, preview image to be taken, obtain photographic images.
In the embodiment of the present invention, terminal can be taken preview image by its built-in taking module, obtains photographic images.Wherein, this taking module can comprise camera, watermark camera, and other have the APP etc. of shoot function, and the embodiment of the present invention is not construed as limiting.
Terminal, at startup taking module, after entering shooting interface, can show current preview image at shooting interface in real time.When terminal detects the shooting instruction of the user operation terminal taking button maybe virtual shoot function key-press input that comprises of this shooting interface, terminal response shooting instruction, takes preview image, obtains photographic images.
S102, generate and comprise the image file of the view data of photographic images.
In the embodiment of the present invention, terminal, after acquisition photographic images, converts image information to data message automatically, generates the image file comprising the image data information of photographic images, and with certain stored in file format.
For example, this image file can comprise multiple file format, such as: jpeg file form, tiff file form and JFIF file format etc., the embodiment of the present invention is not construed as limiting.The photographic images of acquisition decomposes by terminal, resolves into a lot of pixel, and each pixel numerical value represents its gray scale, and the data information memory that terminal forms these gray values is in certain image file format.
The audio signal of terminal surrounding in S103, the rear preset time period of acquisition shooting.
In the embodiment of the present invention, the audio signal of terminal surrounding in preset time period can be obtained by the module with sound-recording function of terminal built-in.Wherein, this module can comprise the sound transducers such as the microphone of terminal built-in or peripheral hardware, and this audio signal is the signal of telecommunication converted to by voice signal, can carry the regular sound wave frequency, changes in amplitude information etc. of voice, music and audio.
In the embodiment of the present invention, because the memory space of image file is restricted, the audio signal obtained is unsuitable long, thus the time period obtaining audio signal must be set in advance, as long as the capacity obtaining the audio signal in this preset time period is no more than memory space, this preset time period can be 5S or 10S etc., and the embodiment of the present invention is not construed as limiting.
In the embodiment of the present invention, the audio signal of terminal surrounding can comprise environmental audio signal, such as: noisy KTV, sound of sea wave, birthday party and concert etc., one section of recording that after also can comprising shooting, user is recorded by terminal, the embodiment of the present invention is not construed as limiting.
S104, according to audio signal generate audio file.
In the embodiment of the present invention, the specific implementation that terminal generates audio file according to audio signal can comprise the following steps:
11) in preset time period, sampling is carried out to audio signal and obtain audio signal samples;
12) audio signal samples obtained of sampling is processed, obtain the audio file comprising voice data.
In the embodiment of the present invention, audio signal is analog signal, need first to sample to audio analog signals, obtain audio signal samples, then quantification treatment is carried out to the audio signal samples obtained of sampling, sampled and numerical data after quantizing, whole process is analog/digital conversion, converts audio analog signals to audio digital signals.
In the embodiment of the present invention, through analog/digital conversion audio signal and the audio file that generates can store, this audio file can be preserved with AMR form, and wherein, this AMR format compression is larger, can store the audio signal of section for more time.
In the reserved location that S105, the voice data write image file comprised by audio file are specified, to generate the target image file carrying voice data.
In the embodiment of the present invention, the specific implementation of step S105 can comprise the following steps:
13) format information that image file comprises is resolved, to find the reserved location in format information;
14) voice data that described audio file comprises is read;
