[Prior Art] [0002] In the camera system, the image is indispensable for previewing images and video by the display, but under the sun or in an overly bright environment, the display screen will appear dark, resulting in screen content. Can not see clearly, under normal circumstances, the user needs to set the brightness required by the display unit in the display function table for different scene modes. The display function table has determined several brightness ranges that can be adjusted before leaving the factory, and the user goes as needed. select. [0003] However, for some reason, such as continuous shooting in different brightness environments, there is generally a mismatch between the ambient brightness and the preset brightness in the scene mode preset by the user, which cannot meet the user's preview requirement, such as Increasing the brightness of the display from the beginning will result in excessive power loss and excessive battery drain.

[0011] The memory 20 has a brightness adjustment program 21 and a built-in table 220. The brightness adjustment program 21 is used to adjust the brightness of the display 3, and the built-in table 220 has corresponding storage. Ambient brightness and display brightness 〇 [0012] The brightness adjustment program 210 includes a parameter preset module 211, an image acquisition module 213, an ambient brightness calculation module 215, a comparison processing module 217, and brightness search. The module 219 and a brightness adjustment module 22 [0013] the parameter preset module 211 is configured to preset various parameters of the program operation, and the preset parameters include a desired brightness, a preset ambient brightness, an aperture value, Exposure time and sensitivity (ISO). Wherein, the desired brightness is an inherent parameter of the photographing apparatus 100, and the preset ambient brightness can be calculated based on the aperture value, the exposure time, and the sensitivity (ISO). [0014] The image acquisition module 213 is configured to acquire a scene image sensed by the photographing device 1 and output the collected data <» understandable, the image sensing device 10 thereof It can be a CCD (Electronic Coupling Device). [0015] The ambient brightness calculation module 215 is configured to calculate an ambient brightness of the sensed image. The ambient brightness value is calculated by the image sensed by the image sensing device 10 in conjunction with the desired brightness, the preset ambient brightness, the aperture value, the exposure time, and the sensitivity (ISO). [0016] The comparison processing module 217 is configured to compare the ambient brightness with the preset ambient brightness to determine whether the external ambient brightness is stable. When the ambient brightness is equal to the preset ambient brightness, the external environment brightness is stable, the comparison 096151280 Form No. A0101 Page 6 / 14 pages 1003302698-0 1355.191 ___ 100 years August 18 revised replacement page processing module issued The brightness search command; when the ambient brightness is not equal to the preset environment temperature, the external environment brightness is unstable, and returns to the parameter preset module 211. [0017] The degree-free search module 219 is configured to respond to the comparison processing module to issue a brightness search command, perform a table lookup in the built-in table 22, and find a display brightness corresponding to the calculated ambient brightness. It can be understood that the built-in table 220 corresponds to the stored ambient brightness and the display brightness as empirical values, and the photographing device 100 uses different sensing devices, and the corresponding values may also be different.

[0019] Please refer to FIG. 2, which is a method for adjusting the brightness of the photographing device 1 according to an embodiment of the present invention, for collecting ambient brightness by using the image sensing device 10 and adjusting the brightness value of the screen to make it The ambient brightness matches. The brightness adjustment method includes the following steps. [〇〇2〇] Step S802, the brightness adjustment program is turned on. [〇〇21] Step S804' presets the parameter value. The parameter values include an aperture value, an exposure time and an sensitivity (ISO); a preset ambient brightness; a desired brightness; a photographic image detected by the photographic plant 100. The preset ambient brightness may be by the preset aperture The value, the exposure time, and the sensitivity (ISO) are calculated, and the image of the scene sensed by the photographing device 100 is the brightness value of the light that is currently sensed by the image sensing device 1 [》22] Step S806, obtaining The photographing device 1 detects the scene image. 〇9615128〇Form No. A0101 Page 7/14 pages 1003302698-0 1355191 [0023] August 2014 Ϊ8&Just correct replacement page Step S808, calculating the ambient brightness of the image" further includes the following steps: using the photographing apparatus 100 The sensed scene image is combined with the desired brightness, and the ratio or difference between the scene image and the desired brightness is calculated, and the aperture value and exposure of the photographing device 100 are continuously adjusted by using the ratio or difference between the scene image brightness and the desired brightness. Time and sensitivity (ISO) until the brightness of the scene image sensed by the photographing device 100 reaches the desired brightness, output aperture value, exposure time and sensitivity (ISO), and use aperture value, exposure time and sensitivity (ISO) Calculate the new ambient brightness. The relationship is as follows: ambient brightness = aperture value + exposure time - sensitivity (ISO). [0024] Step S810, comparing the ambient brightness with the preset ambient brightness to determine whether the ambient environment brightness is stable. If the ambient brightness is equal to the preset ambient brightness, indicating that the ambient environment brightness is stable, proceed to the next step S812; if the ambient brightness is not equal to the preset ambient brightness, indicating that the ambient brightness is changing, return to the preset parameter. In step S804, the parameter values are reset to prepare for recalculating the ambient brightness. [0025] Step S812, performing a table lookup in the built-in table 220 to find the brightness of the display corresponding to the brightness of the environment. It can be understood that the brightness of the display corresponding to each ambient brightness in the built-in table 220 is an empirical value. Since the sensing device used by each of the photographing devices 100 is different from the display 30, an experiment is needed to find the optimal pairing combination. . [0026] Step S814, adjusting the brightness of the display, and driving the display 30 to have the brightness as the display brightness corresponding to the ambient brightness. [0027] The brightness of the external environment is determined by using the image of the scene sensed by the photographing device 100 as a reference for the external brightness, and the corresponding matching fire is found 096151280 Form No. A0101 Page 8/14 pages 1003302698-0 1355.191 100 On August 18th, the replacement of the page brightness value can be achieved, so that the user can clearly see the effect of the image or video on the screen with the lowest screen brightness, thereby saving the battery of the camera device while clearly previewing.
