Description
Technical field
The present invention relates to a kind of digital camera and select the method in focusing zone.
Background technology
Digital camera has promptly to clap and promptly gets and the machinable characteristics of image, and along with popularizing of computing machine and improving constantly of digital camera articulation, digital camera is received users' welcome gradually.
Digital camera partly is made up of camera lens, charge-coupled device (CCD), A/D converter (A/D), microprocessor (MPU), internal memory, LCD (LCD), removable memory (PC card) and computer interface etc., have only the effect of camera lens identical in the digital camera with general camera, it with convergence of rays to sensor devices CCD, CCD is a semiconductor devices, it has replaced the position of film in the general camera, and its function is that light signal is changed into electric signal.So just obtained electronic image corresponding to photographed, then, ADC according to the requirement of computing machine with electronic image from the analog signal conversion to the digital signal, next MPU compresses digital signal and is converted into specific picture format, for example jpeg format.At last, image file is stored in the internal memory.So far, the groundwork of digital camera is finished, and what be left to do is to check the photo that photographs by LCD.LCD is except being used to check the photo that photographs, and two other major function is: show viewfinder image and function menu when finding a view.
The same with general camera, digital camera also improves the sharpness of imaging by focusing.General digital camera all has the automatic focus function of multiple spot, and automatically focusing is meant that camera self can adjust the distance between sensor devices and the camera lens, makes a kind of more clearly technology of imaging, does not need artificial participation.The common automatic focus function of multiple spot of digital camera has 3 focusings, 5 focusings etc.When the user wishes to switch the focusing zone, need press the digital camera shortcut, show the focusing frame on the display screen of digital camera, be the focusing zone in the frame, activate key activates all focusing frames of digital camera, but makes the focusing frame be in selection mode, uses the focus selection of frame of digital camera upper and lower, left and right button then, press acknowledgement key at last the selection of focusing frame is come into force, focus automatically with the zone in this frame of focusing during digital camera imaging afterwards.
This mode operation steps is many, can not realize focusing quick location, the selection in zone, and user's regioselective efficient of focusing is low.When the user watches camera to find a view display screen, if when the user wants to make a unintelligible zone focusing to become clear, need press the camera button and operate and just make the focusing zone elect the zone of wanting as, use like this to lack intuitive, it is inconvenient also to cause operating.
Need be when the user uses aforesaid way to select the focusing zone at phase hands-operation button, general digital camera button is less, makes operation lack comfortable feel, inconvenience.
In addition, digital camera has many functions to select for users, for example sharpness, Exposure mode, exposure compensating, shutter speed, Exposure Metering or the like, if each function is all set button for, that digital camera is just quite complicated.So at present digital camera all uses LCD to come display menu, carries out the selection of menu item with the upper and lower, left and right button, make after menu item selects to come into force pressing acknowledgement key, digital camera is carried out the function of menu item demonstration.Like this, use a small amount of button just can control and realize multiple function.But the method for this choice menus item, the same existence used shortage intuitive, unhandy shortcoming.
Touch-screen is a kind of by touch the computer input method of determining position, indicating positions on screen, and the touch-screen of multiple principles such as resistance-type, condenser type, infrared type, surface acoustic wave type is arranged.
The ultimate principle of touch-screen is: when being installed in the touch-screen of display front end with finger or the touch of other object, the position that is touched, the position is determined with coordinate form, touch screen controller passes through interface with detected touch point positional information, as the RS-232 serial port, deliver to microprocessor, thereby determine the information of input.Touch-screen system generally comprises two parts: touch screen controller (card) and touch screen detection device.The main effect of touch screen controller (card) is the simulating signal that receives touching position information from touch screen detection device, and converts it the digital signal of coordinate to, gives microprocessor again, and its can receive the order that microprocessor sends simultaneously and be carried out.Touch detecting apparatus generally is installed in the front end of display, and main effect is the touch location that detects the user, and sends the touch-screen control card to.
At present, touch screen technology is fairly perfect, because touch-screen has intuitive and simple to operate, be applied in usually on the equipment such as cash machine, user's service computer terminal and realize function selecting, but also in small-sized digital products such as digital camera, be not applied.
Summary of the invention
In view of this, fundamental purpose of the present invention is to provide a kind of digital camera to select the method in focusing zone, and this method makes is selecting focusing region operation efficient height, and operates directly perceived, simple and convenient.
For reaching above-mentioned fundamental purpose, the invention provides the method that a kind of digital camera is selected the focusing zone, be used for a kind of digital camera, this digital camera comprises display screen, digital camera main frame at least, and this digital camera main frame comprises microprocessor at least; Described display screen is a touch display screen, and described digital camera also comprises: touch screen detection device, touch-screen control device and touch screen interface;
Described touch display screen links to each other with touch screen detection device; Touch screen detection device links to each other with the touch-screen control device, and the touch-screen control device links to each other with microprocessor by touch screen interface; After this touch screen detection device detects touch display screen and is touched, the positional information that is touched is sent to the touch-screen control device, the touch-screen control device sends to microprocessor with the coordinate information that positional information is converted to touched point by touch screen interface; Described microprocessor is according to the coordinate information of touched point, on the finding a view of the current demonstration of touch display screen, show the regional icon of current focusing, and to focusing automatically or according to the coordinate information of touched point in this focusing zone, on the menu of the current demonstration of touch display screen, select the menu item at place, touch point, and carry out the function of this menu item; This method may further comprise the steps:
1) wide, the height of touch display screen is respectively H, V; H is divided into M part, V is divided into N part touch display screen and is divided into M * N focusing zone, and the zone of wherein focusing is more than one;
2) after touch screen detection device detects touch display screen and is touched, the positional information of the simulation of touched point is sent to the touch-screen control device, the touch-screen control device is converted to the positional information of simulation the coordinate (x of the numeral of touched point, y) information sends to microprocessor by touch screen interface;
3) microprocessor according to this coordinate (x, y) information calculations goes out touched point and belongs to which focusing zone, and to be set to chosen focusing regional in the zone of should focusing;
Concrete computing method are: establish m, n is an integer, 1≤m≤M, 1≤n≤N;
If: (m-1) * (H/M)＜x≤m * (H/M), (n-1) * (V/N)＜y≤n * (V/N),
