By above control procedure, can grip leftward, in the process of right hand touch operation, with left-hand finger, control physical button (volume increases button, volume reduces button and returns to button), substitute the crucial control operation that needs the right hand to complete in shooting process, discharged the right hand.Grip palm and approach with the neural feedback of operation finger, can be good at mutual coordination, avoid trembling, guaranteed the camera stability in shooting process.
In concrete application, the function that user can go smart mobile phone to take a picture, make a video recording, focus with a hand completely.With same physical hardware (utilizing the upper and lower key of volume of smart mobile phone), go to control and take a picture, make a video recording, focus.Load the menu of a smart mobile phone camera module.When selecting photo, smart mobile phone physical hardware is realized camera function, and when selecting video, physical hardware is realized camera function, then by once making a video recording and finish and preserve.When selecting zoom, realize the focus adjustment function of camera installation, press key focal length and become large, press key focal length and diminish.
Complete smart mobile phone camera module and load three menu items, select different function corresponding to item, concrete contrast is as follows:
Photo completes camera function
Video completes camera function
Zoom completes the adjusting of focal length
Select after corresponding option, the function of physical hardware will be mapped.
When clicking physical hardware, the application program at place can be accepted the key event event that the operating system of smart mobile phone is sent.At this moment we need to do out at this interface as judged:
Obtain the options of three menu items, both can know that pattern (being photograph or shooting or the focus adjustment) later stage that user selects can corresponding different processing for different parameter values.
Obtain the corresponding parameter value of physical hardware, we need to know it is which physical parameter value is the upper key of physics volume or the physics return key of lower key or mobile phone accordingly.(these keys can be realized above-mentioned function and only need in code, define and judge without any difference).After in follow-up implementation, different physical hardwares triggers, being seen effect is also different: such as key definition in physics volume is for tuning up focal length, under physics volume, key is just defined as and turns focal length down.The definition of concrete physical hardware can be done following regulation:
Key under KEY_VOLUME_DOWN physics volume (while pressing key, this event can trigger)
Key in KEY_VOLUME_UP physics volume (while pressing key, this event can trigger)
KEY_CANCEL physics return key.
At camera, the monitoring that all photograph, shooting and zoom regulate is set:
When menu, choose and when photo triggers KEY_VOLUME_DOWN, KEY_VOLUME_UP, be judged as physical hardware and respond, user selects is the function that monitor that photo pattern can be called photo completes photograph;
When menu, choose and when Video triggers KEY_VOLUME_DOWN, KEY_VOLUME_UP, be judged as physical hardware and respond, user selects is the function that monitor that Video pattern can be called Video completes shooting.When having recorded, again click the preservation work that physical hardware can complete video recording.This is the difference of Video pattern and Photo pattern maximum.Here also do the processing of some optimizations, when user carries out pressure test.Meeting click physical hardware repeatedly, triggering each time, system just can be opened up new internal memory and be gone to carry out this operation.Enough there will be system recording frequently time and this is irrational at the interface of preserving.Here we need to do at 2 and go to solve this phenomenon: 1 carries out the synchronous working of the processing resource of each internal memory of newly opening up.Also just say that each time period only allows an internal memory to go to process this resource.Record or deposit, taking exactly locking protection mechanism, when using this resource, will obtain the lock of this resource, guaranteeing the uniqueness of using.The maximum probability that 2 experimental verification problems by repeatedly occur be just to go immediately to carry out storage after just having started shooting.Thereby cause above-mentioned phenomenon.In code, we can design like this: must shooting time when being video pattern surpass and just allow preservation (record camera time length go forward side by side the judgement of line time length) after 2S.So just greatly reduce the generation of above-mentioned situation.
As menu setecting Zoom, and trigger KEY_VOLUME_DOWN, KEY_VOLUME_UP(be here long by) time, can complete the process that physical hardware is focused, concrete implementation method is as follows:
The focal length variations of any camera installation is all certain limit, the hardware of this and concrete camera installation has very large relation, first we need to obtain these information from bottom, obtain maximum zoom multiple (for during simplifying, take 4 times here as example).
At equipment, take a picture, in the process of photography, whether anti-shake etc. equipment can periodically go to read these parameters of current parameters (whether ratio exposes, time for exposure, which kind of pattern motion, night), and we can be placed in parameter variable by unified handles.Thereby change current photograph effect.So my way is periodically to remove to arrange zoom multiple, it is left in parameter variable, system periodically goes to read again, the focal length in the time of just can changing photograph, photography.
The size that focus is set is 100, and minimum value is 1, and maximum is that 400(focus/100 retains one decimal place current multiplication factor in time).Arrange two different scale when trigger long while pressing on physical hardware key (being defined as enlarging function) on the contrary scale=0.9<1 when scale=1.1>1 triggers lower key.
In system, the long hardware of pressing physics can periodically trigger KEY_VOLUME_DOWN, KEY_VOLUME_UP event, is periodically multiplied by so in the method this scale, just can realize the amplification of focus and dwindle.Focus=focus x scale(scale=1.1>1 when judgement is KEY_VOLUME_UP) focus progressively increases.
Focus=focus x scale(scale=0.9<1 when judgement is KEY_VOLUME_DOWN) focus progressively reduces just can calculate current multiplication factor finally by crossing simple mathematical computations.
Again by the setting in this multiplication factor cycle (set) in parameter, system periodically removes to obtain (get) this parameter again.Just complete whole circulation, reached the process that physical hardware carries out zoom.
Above-described embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not departing from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention, all should fall in the definite protection range of the claims in the present invention book.
