The implementation of the object, functional characteristics and advantages of the present invention will be further described in combination with the embodiments and with reference to the accompanying drawings.
It should be understood that the specific embodiments described here are only used to explain the present invention, which is not used to limit the present invention.
With reference to
In step S101, divide a photosensitive area of a photosensitive element into at least two subareas.
The photosensitive element may be a Complementary Metal Oxide Semiconductor (CMOS) and a Charge Coupled Device (CCD) and so on. The purpose of dividing the photosensitive area of the photosensitive element into subareas is to make it convenient for independently controlling photosensitive parameters of each area of the photosensitive element, the more the divided subareas are, the stronger controllability to the photosensitive element is.
In step S102, display all subareas of the photosensitive area.
A user may enter a setup menu to adjust photosensitive parameters of each subarea before or after opening a camera application, or may trigger a function of adjusting photosensitive parameters according to a preset operation instruction such as touching, clicking a preset location or pressing a preset function key after opening the camera application. The photographing device then displays an adjustment interface and displays all the subareas of the photosensitive area on the screen.
In step S103, select subareas according to a user instruction, and acquire photosensitive parameters required by the user.
The user may select corresponding subareas by clicking or touching the screen, and after the subareas are selected, an input interface or an adjustment interface for the photosensitive parameters is immediately displayed in photographing for the user to choose or input the required photosensitive parameters, and the photosensitive parameters selected or input by the user are acquired. The photosensitive parameters may be one or any combination of exposure time, white balance and photosensibility (ISO) and so on. Herein, the exposure time may be used for adjusting luminance, the white balance may be used for adjusting color cast, and the photosensibility may be used for adjusting light sensitivity.
In step S104, adjust the photosensitive parameters of the selected subareas to the photosensitive parameters required by the user.
The user may also adjust other subareas after adjusting photosensitive parameters of one subarea, so as to implement custom settings on the photosensitive parameters of each subarea respectively.
In step S105, perform photographing according to the photosensitive parameters of each subarea of the photosensitive element.
Specifically, when a photographing key is triggered, the photographing device collects image data, and exposures various parts of the image data respectively according to the photosensitive parameters of each subarea of the photosensitive element, and eventually generates a photograph. Since the photosensitive parameters of each subarea of the photosensitive element are adjusted respectively, the generated photograph has a brighter color, richer details and a clearer image.
For example, the photosensitive element is divided into a plurality of subareas from top to bottom, the exposure time of each subarea is adjusted, the exposure time is increased gradually from top to bottom, so that the luminance of the shot photograph is increased gradually from top to bottom. Or, the photosensitive element is divided into a plurality of subareas from left to right, the white balance of each subarea is adjusted, the white balance is increased gradually from left to right, so that the color cast of the shot photograph is changed gradually from left to right. Adjustments can also be performed regarding to the specific conditions of each area respectively, if the left light of the scenery is stronger, the exposure time of the corresponding subareas of the photosensitive element may be shortened to avoid overexposure, and if the right tone of the scenery is cooler, the white balance of the corresponding subareas of the photosensitive element may be adjusted to warm the tone. Moreover, a combination of any two of the photosensitive parameters like exposure time, white balance and photosensibility may also be adjusted, or a combination of any multiple kinds may be adjusted, in a word, the user may shoot a photograph with various effects according to his/her own individualization needs, which enhances the photographing effect and satisfies the user's individualization needs.
With reference to
In step S201, divide a photosensitive area of a photosensitive element into at least two subareas.
In step S202, display a preview image of a photographed scenery.
The embodiment allows the user to adjust the photosensitive parameters in a photographing process or after opening a camera application, and the photographing device generates the preview image of the photographed scenery at this point and displays the preview image on the screen.
In step S203, select an adjustment area on the preview image according to a user instruction.
The user may directly touch or click a certain location of the preview image, and the photographing device selects the location as the adjustment area.
In step S204, determine subareas of the photosensitive area corresponding to the adjustment area, and acquire photosensitive parameters required by the user.
Various areas on the screen and various subareas of the photosensitive element are in one-to-one correspondence, the photographing device determines the corresponding subareas according to the adjustment area selected by the user on the screen. Meanwhile, the photosensitive parameters input or selected by the user are acquired.
In step S205, adjust photosensitive parameters of the subareas corresponding to the adjustment area to the photosensitive parameters required by the user.
The user may also adjust other subareas after adjusting photosensitive parameters of one subarea, so as to implement custom settings on the photosensitive parameters of each subarea respectively.
Alternatively, after the adjustment on photosensitive parameters of one subarea is completed, a preview image is immediately regenerated according to the adjusted photosensitive parameters and is displayed, so that the user may check the image effect in real time to decide whether it is required to continue the adjustment.
In step S206, perform photographing according to the photosensitive parameters of each subarea of the photosensitive element.
The embodiment allows the user to select the adjustment area on the preview image for performing photosensitive parameter adjustment, so that the adjustment process is more visualized, the image effect after the adjustment may be checked in real time, so that the user may rapidly create satisfying works.
In certain embodiments, the photographing device may also automatically adjust the photosensitive parameters of each area of the photosensitive element according to the preset rules or conditions.
Therefore, with the photographing method of the present invention, by dividing the photosensitive area of the photosensitive element into a plurality of subareas, each subarea may be controlled independently, and especially photosensitive parameters of each subarea may be adjusted respectively, it is equivalent to a controllable optical filter, and photographing is performed according to the photosensitive parameters of each subarea of the photosensitive element, so that a photograph obtained by photographing has a brighter color, richer details and a clearer image, which enhances the photographing effect and improves the user experience.
