[0011] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0012] Please refer to Figure 1 , Figure 1 1 is a flow chart of a method for controlling image capture according to an embodiment of the present invention. In step S110, the electronic device that performs the image capture action may provide a plurality of to-be-selected capture algorithms. The electronic device may also set one of the to-be-selected capture algorithms as a selected capture algorithm in step S120, wherein the electronic device may provide a menu with a plurality of to-be-selected capture algorithms for the user to select. The user may perform the selection action by inputting a command. Thus, the electronic device may set one of the plurality of to-be-selected capture algorithms as the selected capture algorithm according to the user's input command.

[0013] Next, the electronic device can further set the algorithm parameters of the selected shooting algorithm. The electronic device can also provide a menu of multiple algorithm parameters of the selected shooting algorithm for the user to adjust the algorithm parameters through another input command. In step S130, the electronic device can set the multiple algorithm parameters of the selected shooting algorithm according to the input command.

[0014] In step S140, the electronic device may perform an image capture operation of N image frames according to the set algorithm parameters, thereby obtaining a plurality of captured images. Furthermore, in step S150, the electronic device may further perform an image processing operation of the captured images according to the algorithm parameters, perform image synthesis on the processed captured images, and thereby generate an output image.

[0015] In this embodiment, the electronic device allows the user to select and set the shooting algorithm and related algorithm parameters. In this way, the user can have more control over the image shooting action and can shoot photos with a special style.

[0016] Please refer to the following Figure 2 , Figure 2 2 is a flow chart of a control method for image capture according to another embodiment of the present invention. The image capture action of this embodiment can be performed by an electronic device, wherein the electronic device has a controller and an image capture device. In step S210, the controller can control the image capture device to perform a preview action on the shooting scene, and further, the controller generates a plurality of shooting algorithms to be selected according to the shooting scene obtained in the preview action. The controller can also provide shooting algorithms to be selected for the user to select, and in step S220, a selected shooting algorithm is selected from a plurality of shooting algorithms to be selected according to the user's input command. In detail, the electronic device can have a display interface and an input interface. The controller can display the relevant information of the shooting algorithms to be selected that can be provided through the display interface. The controller can also receive the user's input command through the input interface, and then set the selected shooting algorithm according to the input command.

[0017] Incidentally, in this embodiment, in order not to limit the user's creativity, the controller can display all available information about the shooting algorithms to be selected on the display interface. On the other hand, the controller can, for example, display the shooting algorithms to be selected according to the brightness of the shooting scene, and display the order of the shooting algorithms to be selected recommended by the electronic device in this shooting scene through the arrangement order of the information of the multiple shooting algorithms to be selected on the display interface.

[0018] In simple terms, the controller may display the information related to the best recommended candidate shooting algorithm at the front position, and display the information related to the second-best recommended and unrecommended candidate shooting algorithms in sequence at the back position. Of course, through the user's setting, the controller may also display the information related to the least recommended candidate shooting algorithm at the front position, and display the information related to the second-best recommended and best recommended candidate shooting algorithms in sequence at the back position.

[0019] Next, in step S230, the controller may set multiple algorithm parameters of the selected algorithm. In detail, the controller may display the algorithm parameters of the selected shooting algorithm through a display interface. In addition, the user may input various algorithm parameters through an input interface. Among them, each algorithm parameter displayed on the display interface may have a default value, and the user may adjust any algorithm parameter through the input interface. According to the user's input command, the controller may complete the setting of multiple algorithm parameters of the selected shooting algorithm.

[0020] In step S240, the controller may perform an image capturing operation according to the algorithm parameters through the image capture device, and obtain captured images corresponding to a plurality of image frames (image frame 1 to image frame N) in step S250. In step S260, the controller may perform an image processing operation on the plurality of captured images according to the algorithm parameters to generate an output image, and terminate the process.

[0021] Incidentally, in this embodiment, the selected shooting algorithm includes at least one of a high dynamic range (HDR) algorithm and a night shooting algorithm. Corresponding to the high dynamic range algorithm, the algorithm parameters include the number of captured images corresponding to multiple exposure values. The multiple exposure values ​​are, for example, positive exposure values, zero exposure values, and negative exposure values.

[0022] It is worth noting that in the embodiment of the present invention, after step S260, an additional algorithm of one level can be superimposed. For example, when the selected algorithm is a high dynamic range algorithm, a red-eye removal algorithm is additionally superimposed to further improve the quality of the output image. In the embodiment of the present invention, after the image processing actions of multiple image frames, one or more image processing actions of a single image frame can also be serially connected. It is not limited to the aforementioned red-eye removal algorithm.

[0023] Please refer to the following Figure 3 , Figure 3 is a flow chart of a control method for image capture according to another embodiment of the present invention. The image capture action of this embodiment can also be performed by an electronic device having a controller, a display interface, an input interface, and an image capture device. Among them, in step S310, the controller can control the image capture device to preview the shooting scene, and further, the controller generates a plurality of shooting algorithms to be selected according to the shooting scene obtained in the preview action. The controller can also provide the shooting algorithms to be selected for the user to select, and in step S320, a selected shooting algorithm is selected from the plurality of shooting algorithms to be selected according to the user's input command.

[0024] Next, in step S330, the controller may determine whether the selected shooting algorithm is a high dynamic range (HDR) algorithm. If the controller determines that the shooting algorithm is an HDR algorithm, step S340 may be executed; conversely, if the controller determines that the shooting algorithm is not an HDR algorithm, step S350 may be executed.

[0025] In step S340 , the controller may set a plurality of algorithm parameters of the HDR algorithm according to the input command, such as the number n1 ˜nA of captured images corresponding to a plurality of exposure values ​​EV1 ˜EVA respectively.

[0026] In step S350, the controller may use the image capture device to perform an image capture operation according to the algorithm parameters. In this embodiment, the controller may control the image capture device to capture images of number n1 to nA at multiple exposure values ​​EV1 to EVA. Thus, in step S360, captured images corresponding to multiple image frames (image frame 1 to image frame N) may be obtained.

[0027] In step S370 , the controller may perform image processing on the plurality of captured images according to the algorithm parameters to generate an output image, and then terminate the process.

[0028] It is worth noting that, in the embodiment of the present invention, after step S370, based on the selected algorithm being a high dynamic range algorithm, a red-eye removal algorithm may be additionally superimposed to further improve the quality of the output image. Similarly, in the embodiment of the present invention, after the image processing actions of multiple image frames, one or more image processing actions of a single image frame may be serially connected. It is not limited to the aforementioned red-eye removal algorithm.

[0029] Please refer to the following Figure 4 , Figure 4 4 is a schematic diagram of an electronic device according to an embodiment of the present invention. The electronic device 400 includes a controller 410, an image capturer 420, a display interface 430, and an input interface 440. The controller 410 is coupled to the image capturer 420, the display interface 430, and the input interface 440. The controller 410 can be used to perform the following operations: Figures 1 to 3 The controller 410 can be designed by a hardware description language (HDL) or any other digital circuit design method known to those skilled in the art, and implemented as a hardware circuit by a field programmable gate array (FPGA), a complex programmable logic device (CPLD) or an application-specific integrated circuit (ASIC).

[0030] The image capture device 420 may be a camera, or other devices known to those skilled in the art that can capture static or dynamic images, without particular limitation.

[0031] It is worth mentioning that the display interface 430 and the input interface 440 can be two independent devices, or they can be integrated with each other. Among them, in one embodiment of the present invention, the input interface 440 can be a touch interface in any form, and is integrated with the display interface 430. In this way, the user can input the input command by performing a touch action on the input interface 440. In another embodiment of the present invention, the input interface 440 can be any input device such as a keyboard or a mouse that is well known to ordinary technicians in the field, and it may not be integrated with the display interface 430. In an embodiment of the present invention, the display interface 430 can be a display in any form, and there is no fixed restriction.

[0032] In summary, in the image capture control method of the present invention, by opening the selection of the selected capture algorithm and opening the setting action of the algorithm parameters of the selected capture algorithm to the user, the freedom of the user's image capture action can be improved, and a more creative output image can be obtained.
