Embodiment
With reference to the accompanying drawings the useful embodiment among the present invention is described in detail.
Fig. 1 shows the pie graph with mobile communication terminal of screening-mode auto-conversion function of the present invention.
As shown in Figure 1, the mobile communication terminal with screening-mode auto-conversion function of the present invention is made of camera section 110, illumination photometry portion 120, control part 130, memory section 140 and display part 150.
At first, camera section 110 has the filming image means of set camera etc., is used to take pictures or activity video etc.
The general action of control part 130 control mobile communication terminals compares the illumination critical value that sets in advance and preserve from the brightness value of the photo of above-mentioned illumination photometry portion 120 inputs or activity video etc. and memory section 140.At this moment, when judgement thinks that when the brightness value of above-mentioned illumination photometry portion 120 inputs was lower than the illumination critical value of preserving the memory section 140, control part 130 was controlled, the screening-mode of camera section 110 is automatically converted to white-black pattern from color mode.
Preserve the set program of all actions of control mobile communication terminal in the memory section 140, image datas such as set photo of taking to input in the program operation process, output and the various data of handling with from camera section 110 and activity video are preserved.In addition, also preserve the illumination critical value that the user imports in advance.
Below with reference to Fig. 2, further describe the method that " mobile communication terminal with screening-mode auto-conversion function " that use as above constitutes changes screening-mode automatically.
Fig. 2 is the precedence diagram that shows the automatic switching method of screening-mode in the mobile communication terminal of the embodiment of the invention successively.
As shown in Figure 2, the screening-mode automatic switching method of mobile communication terminal of the present invention is as follows: at first, the user begins to take pictures and activity video (step S210) by the camera section 110 of mobile communication terminal.Then, control part 130 is controlled, make mobile communication terminal acquiescence move (step S215) with color mode, the illumination photometry portion 120 of sensing light utilizes set transducers such as optical sensor, measure the brightness value of the surrounding enviroment of mobile communication terminal, and output to control part 130 (step S220).
Its control part of confirming 130 for to comparing with the illumination critical value that sets in advance from illumination photometry portion 120 input brightness values, is confirmed whether preserve the illumination critical value (step S225) that sets in advance in the memory section 140.
Wherein, when not preserving the illumination critical value that sets in advance in the memory section 140, the user can be provided with set illumination critical value.For this reason, control part 130 confirms whether the user will be provided with illumination critical value (step S230).At this moment, when the user was not provided with the illumination critical value, mobile communication terminal continued acquiescence and moves (step S260) with color mode; When the user is provided with the illumination critical value, after the value of user's input is set to the illumination critical value, be stored in (step S235) in the memory section 140.
As mentioned above, when preserving the illumination critical value that sets in advance in the memory section 140, the illumination critical value that sets in advance in the control part 130 comparison memory section 140 and the brightness value (step S240) of the surrounding enviroment that illumination photometry portion 120 measures in above-mentioned steps S220.Wherein, when the brightness value of the surrounding enviroment of measuring when illumination photometry portion 120 is lower than the illumination critical value that sets in advance of preserving in the memory section 140 (step S245), control part 130 keeps the illumination photometry (step S250) of illumination photometry portion 120 in the set time.
For example, setting in advance in the illumination critical value is under the state of 10 Luxs (LUX), and control part 130 kept for 10 times in second with the brightness value that illumination photometry portion 120 measures, and averaged.
Then, control part 130 confirms whether the brightness value of measuring is the illumination critical value (step S255) that sets in advance, and when the brightness value of measuring during greater than the illumination critical value that sets in advance, keeps color mode (step S260).On the contrary, when the brightness value of measuring is lower than the illumination critical value that sets in advance, control part 130 thinks that the residing particular place of mobile communication terminal is the low-light (level) environment, and the screening-mode of mobile communication terminal is automatically converted to white-black pattern (step S265) from color mode.
For example, setting in advance in the illumination critical value is under the state of 10 Luxs (LUX), control part 130 kept for 10 times in second with the brightness value that illumination photometry portion 120 measures, and when the mean value of getting was 5 Luxs (LUX), the brightness value of mensuration was lower than the illumination critical value that sets in advance.So control part 130 makes the screening-mode of mobile communication terminal be automatically converted to white-black pattern from color mode.
More than useful embodiment of the present invention is illustrated and illustrates, but the present invention is not limited to the above embodiments, under the prerequisite that does not break away from the desired main idea of the present invention of claims, have the affiliated field Chang Shizhe of the present invention and can carry out various deformation enforcement.
In sum, " mobile communication terminal and side thereof with screening-mode auto-conversion function of the present invention Method " have following effect, that is, when the camera section of installing on utilizing mobile communication terminal is taken, sense Know particular place, when being low-light (level), screening-mode is automatically converted to white-black pattern from color mode, from And the filming image that both can carry out high image quality when low-light (level) also can save the time of screening-mode conversion.
