Abstract
The invention discloses a starting method for a mobile terminal camera. The starting method for the mobile terminal camera includes the following steps: (1) the camera is started, and a start mode is read; (2) whether the start mode is a fast mode is judged; (3) if the start mode is the fast mode, a bottom driver starts the camera in the fast mode, and if not, the bottom driver is informed to start the camera in a common mode; (4), a staring process is finished, and normal shooting is carried out; (5) the camera is exited; (6) whether an exit mode is a fast mode is judged; (7) if the exit mode is the fast mode, the bottom driver exits the camera in the fast mode, the camera enters into a standby mode, if not, the bottom driver exits the camera in a normal mode, and the camera is turned off; and (8) the whole process is finished. By means of the starting method for the mobile terminal camera, camera starting is accelerated, and a user can take a candid photograph conveniently.
Description
Technical field
The present invention relates to moving communicating field, specifically the quick start method of the camera of the portable terminals such as a kind of mobile phone, digital camera.
Background technology
Substantially all dispose camera on the present mobile phone, the function of the picture of taking pictures and effect are more and more approaching with some digital cameras.Mobile phone and digital camera need main control chip to pass through a large amount of initiation sequence of certain bus (normally I2C bus) transmission to the ISP chip when opening camera, then the ISP chip internal carries out initialization to these sequences, continuation to the ISP chip, then just had data from camera out from the parameter of main control chip transmission setting after initialization was finished.Finish such process, need long time to go to open the bottom layer driving of camera, usually needed three seconds, four seconds or the longer time.The camera of certain model also need to add some times by open detect around light source just can reach optimum efficiency, it is not fine causing the image effect when just opening camera.If the user was in the state of not opening camera originally, when running into the scene of capturing mutually, just need to reopen camera, this delay of several seconds just may cause capturing unsuccessfully sometimes.In addition, when when tourism is visited, often need some photos of shooting of discontinuity, just have and want the thing captured such as walking several steps, and if within the time of this interruption, keeping terminal equipment to start shooting always, the so unusual electric weight of loss equipment.And if close after having clapped at every turn, need again when again taking pictures again to start shooting and again enter and when waiting for several seconds, often can make the user miss the chance of the beautiful scenery of taking pictures.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of starting method of camera of portable terminal, effectively accelerates the toggle speed of camera, is convenient to the user to the candid photograph of object.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
A kind of Starting mode of mobile terminal camera may further comprise the steps:
(1) starts camera, read start-up mode;
(2) determine whether quick mode;
(3) if bottom layer driving starts with quick mode; If not, the notice bottom layer driving starts with general mode;
(4) finish start-up course, carry out normal photographing;
(5) withdraw from camera;
(6) determine whether quick mode;
(7) if bottom layer driving withdraws from quick mode, makes camera enter standby mode; If not, bottom layer driving withdraws from general mode, closes camera;
(8) finish.
The present invention arranges the quick mode of a startup at the whole camera of the movements such as mobile phone, digital camera, accelerated the toggle speed of camera.Enter quick mode when camera withdraws from, do not need the too many electric weight of loss during the camera standby, and can start fast when restarting, can take pictures at once, can not miss the opportunity of candid photograph, greatly user-friendly.
Description of drawings
Accompanying drawing 1 is principle process schematic diagram of the present invention.
Embodiment
For the ease of those skilled in the art's understanding, the present invention is further illustrated below in conjunction with accompanying drawing.
The present invention has disclosed the starting method of the camera of the portable terminals such as a kind of mobile phone, digital camera, camera interface at portable terminal has general mode and quick mode, a mode list is arranged for user selection, be that the user can have a mode list to eject for user selection, in order to operate accordingly when starting camera and withdrawing from camera.Portable terminal is preserved the quiescent value of this mode list and can not lost because closing of camera opened.
As shown in Figure 1, this method comprises step:
(1) starts camera, read start-up mode.Open camera when the user need to take pictures, and carry out reading of pattern, the user can select according to the actual needs of oneself.
(2) determine whether quick mode.What the processor of portable terminal was judged user selection is that general pattern starts or quick mode starts.
(3) if quick mode starts, then the main control chip of portable terminal is given an order and is notified bottom layer driving to start with quick mode, bottom layer driving only need to enable to supply with clock, the standby pin is pulled to corresponding level or sends wake command by communication interface to camera, the camera picture of at once just can publishing picture improves the toggle speed of camera greatly.If not quick mode but general mode, the notice bottom layer driving starts with general mode.Normal Starting mode according to existing camera starts, and the camera Starting mode of existing mobile phone or digital camera all is to well known to a person skilled in the art knowledge, and in this not go into detail.
(4) finish start-up course, carry out normal photographing.
(5) withdraw from camera.Take complete after in order to save the electric weight of terminal, need in time withdraw from camera.
(6) determine whether quick mode.Judge again when withdrawing from that the user selects to withdraw from quick mode, or withdraw from general mode.
(7) if quick mode, the main control chip notice bottom layer driving quick mode of giving an order withdraws from, then bottom layer driving withdraws from quick mode, makes camera enter standby mode, this moment, camera was in the quick mode state.Under this state, bottom layer driving can not cut off the power supply to camera.Bottom layer driving sends an order by communication interface (being generally the I2C bus interface) to camera, makes camera enter standby mode, perhaps utilizes the standby pin of camera to be pulled to corresponding level and makes camera enter standby mode.The main control chip of portable terminal keeps the power supply to camera, can anergy but supply with clock, enter with one voice behind the standby mode relevant parameter of camera with this and still can not lose, but greatly reduce power consumption, save electric weight, and do not closed camera this moment fully.If general mode withdraws from, then close camera fully, main control chip can not powered to camera, and bottom layer driving is cut off the power supply to camera.
(8) finish whole process.
Portable terminal starts camera to be finished and takes after the purpose, because the user often can just capture at lower one or two minute certain scene, therefore can keep the open state of camera, and the unusual electric weight of loss portable terminal of normal boot-strap state.Enter holding state with quick mode when the inventive method withdraws from camera after starting, when again opening, can wake fast camera up, take pictures, do not need the initialization through program start and the relevant parameter in several seconds at once.
Need to prove, the above is not to be restriction to technical solution of the present invention, under the prerequisite that does not break away from creation design of the present invention, just technical solution of the present invention is made some simple replacements, all within protection scope of the present invention.
