Abstract
A brightness regulation method of mobile communication terminal camera comprises steps of main menu or shortcut key arranged with said terminal by user coming into preview state after shoot is over; in above preview state, if shoot press key is pressed, displaying brightness information of shot picture on the predetermined position of the shot picture at the time of shooting picture in order to adjust brightness by user. The invention has available effect that when mobile communication terminal capable of shooting is used for shooting, in order to adjust brightness of the picture Luminance Histogram is displayed on the shot picture, and brightness regulation method of mobile communication terminal camera capable of shooting more clear picture is available by the reference histogram.
Description
Technical field
The present invention relates to the mobile communication terminal technology, is a kind of brightness regulation method of mobile communication terminal camera concretely.
Background technology
In general, dispose the menu that is used to regulate camera brightness on the mobile communication terminal of more and more having popularized capable of taking pictures recently, can carry out brightness regulation the photo of taking.
But, existing lightness regulative mode be the user after watching picture, by the individual feel to regulate picture brightness, rather than regulate according to the correct brightness information of photo pixel.
That is, under preview (Preview) state of the captured photo of camera, by the service orientation key, feeling when watching photo utilizes the shortcut adjusting of coming in simply; Or under preview state, the open auxiliary menu remains by feeling to carry out the brightness adjustment.In other words, do not provide any comparison film brightness regulation helpful data here.
As mentioned above, regulate original camera brightness, promptly to the adjusting of the picture pixel of captured photo, not to be undertaken by quantitative data, but regulate by individual's sensation, therefore can not correctly grasp photo overall brightness and sensation in advance, simultaneously because each user's sensation all is not quite similar the standard that neither one is unified.Therefore, camera uses today that proportion increases day by day in the terminal capable of taking pictures, and the user also can reduce for the satisfaction of the captured photo of terminal.
Summary of the invention
Therefore, the present invention proposes in order to solve above-mentioned original problem, and its purpose is to provide brightness regulation method of mobile communication terminal camera, promptly when using mobile communication terminal capable of taking pictures to take pictures, can take clear pictures more.
For realizing this purpose, the present invention is when using mobile communication terminal capable of taking pictures to take pictures, for the adjusting of camera brightness, its feature is made of following step: after the user takes pictures by the main menu be furnished with on the above-mentioned terminal or shortcut, and the step that enters preview (Preview) state; In above-mentioned preview state, if press the button of taking pictures, then when this picture is captured, can regulate brightness in order to make the user, the monochrome information of this candid photograph picture is presented at the set locational step of picture; The user regulates brightness with reference to described monochrome information by the brightness setup menu, and the photo after regulating can be preserved; Described monochrome information shows by the picture of chart format.
Described monochrome information also can show under the state of capturing preview screen and preview state in real time.
Camera is taken in the menu and is disposed setup menu, and time that can show monochrome information and whether showing is provided with.
Useful result of the present invention is, by the brightness chart on the mobile communication terminal photo, grasp the monochrome information of each pixel and carry out brightness regulation with this, can select optimal brightness to take, and by checking whether lightness information decision preserves, thereby only preserve those best photos, reduced the past take preserved a plurality of photos after, carry out brightness ratio trouble again, improved the facility in user's use.
Description of drawings
Fig. 1 is based on the schematic diagram of mobile communication terminal camera brightness regulation process of the present invention;
Fig. 2 is the schematic diagram after the brightness chart of Fig. 1 screen displayed amplifies.
Embodiment
The present invention is to provide a kind of method in main purpose, make when using mobile communication terminal capable of taking pictures to take pictures, the parameter of regulating lightness is presented on the brightness chart (LuminanceHistogram) on the captured photo, the user passes through with reference to this chart, can regulate the brightness of camera, thereby shoot clear photograph more.
Describe below with reference to example figure of the present invention.
Fig. 1 is based on the schematic diagram of mobile communication terminal camera brightness regulation process of the present invention, as a of Fig. 1, shown in the b, takes pictures by the main menu or the shortcut (Hot Key) that dispose on the terminal, enters the preview shown in the c (Preview) state afterwards.
Afterwards, in above-mentioned preview state, if press the shooting button, final picture in the above-mentioned preview state can be captured (Capture) and be got off, under picture is captured in, the brightness chart of this candid photograph picture is presented on both allocations of picture.
Therefore, the user checks the brightness of photo, by regulating lightness by key is set by with reference to this brightness chart.After such shooting and regulating,, can press the preservation key and preserve if comparison film pleases oneself.
In the above-mentioned example of this moment, after taking under preview state, the picture of this candid photograph shows the brightness chart, but different terminal production firms, and display brightness chart in real time also under preview state is taken pictures after can regulating brightness earlier again.
Have, whether above-mentioned brightness chart can come time of showing and show to be provided with by setup menu again.
Fig. 2 is in above-mentioned Fig. 1, the schematic diagram after shown brightness chart amplifies on the picture.As mentioned above, be the chart that under preview state, shows or show the monochrome information of taking pictures in real time.That is,, in image, show the function chart of number of pixels with this brightness value at various brightness (Luminance).
In the brightness chart of above-mentioned Fig. 2, horizontal columns is represented brightness value (Luminance value), vertical column remarked pixel number.Aforesaid brightness chart is that the brightness composition that camera is introduced is analyzed, and shows by the mode of software.
As above-mentioned explanation, the present invention is when using mobile communication terminal capable of taking pictures to take pictures, for regulating the brightness of photo, display brightness chart on captured photo (Luminance Histogram), by the reference chart, have and to take the effect of clear pictures more.
Have again, the present invention is by the brightness chart on the mobile communication terminal photo, grasp the monochrome information of each pixel and carry out brightness regulation with this, so be not to feel to regulate brightness by the individual, but regulate brightness by correct data, therefore can select optimal brightness to take, and by checking whether the decision of lightness information preserves, thereby only preserve those best photos, reduced the past after a plurality of photos have been preserved in shooting, carry out brightness ratio trouble again, improved the facility in user's use.
Concrete example that carries out in the detailed description of the invention described above or embodiment are used for clearly stating more technology contents of the present invention, make an explanation with can not being defined in this specific embodiment narrow sense, can in the scope of claims of spirit of the present invention and following record, carry out multiple variation.
