Field of the Invention The present invention relates to a method of adjusting control parameters of a photographing apparatus, and more particularly to a method of rapidly adjusting photographing control parameters of a mobile terminal having a photographing apparatus. [Prior Art] With the development and popularization of digital technology, especially the perfection of digital image output technology, various mobile terminals are moving toward functional diversification, and new terminal products with digital image functions have emerged at a higher level. The level is convenient for people's lives. When using the mobile terminal with the photographic device to shoot in the light, in order to achieve the best shooting effect and obtain an image of appropriate size, it is often necessary to change some control parameters of the photographic device, such as the focal length of the photographic device, the photo obtained by the shooting. Size (hereinafter referred to as image size), shooting environment settings (night scene mode, normal mode), image quality, and so on. For example, in the process of shooting, in order to get the best shooting results, it is often necessary to change the foreground to medium shot, the middle scene to close-range, or in the distant view, the image size from 640 χ 480 to 320 χ 240 and so on. At present, various mobile terminals with photographic devices generally use a function table to provide a user to adjust these parameters, and the upper and lower control buttons of the mobile terminal key input device are used to simply adjust the focal length of the photographic device, but with the digital The technology is improving day by day, and the control parameters of the photographic device are increasing. In order to achieve a better shooting effect, it is still necessary for the user to enter the function table so that most of the shooting parameters can be set before the shooting can be performed. This allows the user to control parameters such as focal length and image size that need to be changed frequently. Adjusting 1234941 is not convenient, the operation process is cumbersome, the speed is slow, and the interaction between the camera and the camera device is difficult to achieve an intuitive effect. In addition, since the digital key of the mobile terminal is always idle in the photographing state of this mode, resources are not fully utilized. Therefore, it is desirable to have a method for conveniently and quickly adjusting the control parameters of the mobile terminal photographing device during the shooting process, so that the photographing device of the mobile terminal has stronger interaction performance with the user, and is more convenient. User's use of a mobile terminal with a camera. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for enabling a mobile terminal having a photographing device to quickly adjust a photographing control parameter using its digital key. Therefore, the method for quickly adjusting the photographing control parameter by the mobile terminal with the photographing device of the present invention comprises the following steps: 1) determining whether the mobile terminal is in the photographing state mode; 2) determining the correspondence between the digit key and the focal length and image size of the photographing control parameter. Relationship; 3) receiving key information of the user from the key input device of the mobile terminal; 4) translating the key value information of the key into the information according to the determined mapping relationship between the key value and the control parameter focal length and image size The parameter for controlling the photographing state; 5) transmitting the control parameter to the driving program of the photographing device through the interface function between the mobile terminal and the photographing device, and controlling the entire photographing process together with other control materials. The digit keys are 1, 2, 3, 4, 5, 6, 7, 8, and 9. The focal lengths corresponding to the digit keys 1, 2, 3, and 4 are 丨 focal lengths, and the corresponding image sizes are 640 χ 480, 320 x 240, i6 〇 x 12 〇, and 20 1249341 128 x 96 数 the digit keys 5 described above. The focal length corresponding to 6,7 is 2 times the focal length, and the image size of the pair is 320χ240, 160χ120 and Ι28χ. The focal lengths of the digit keys 8, 9 are 4 times focal length, and the corresponding image sizes are 160 χ 120 and 128 χ 96, respectively. Compared with the prior art, the present invention can directly adjust some control parameters of the photographic shape in the shooting state by using the correspondence between the digital key and the control parameter of the photographic state, so that the user can be specific according to the shooting process. The dynamic change of the focal length and the image size improves the efficiency of the user using the mobile terminal with the photographic device for shooting, and facilitates the user's use of the mobile terminal's shooting function, thereby enhancing the interaction between the mobile terminal and the user. Furthermore, the mobile terminal appears to be more user-friendly. In addition, the present invention also makes full use of the digital keys that were originally idle during the shooting process, thereby improving the utilization of resources. The above and other technical contents, features, and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments.

In this embodiment, after determining that the mobile terminal is in a photographing state, the mobile terminal first generates a key input signal corresponding to the user's button through the key input device, and the RF signal obtained by the RF module passes through an IF (Intermediate Frequency). After processing, it is converted into a digital signal. The converted digit § is input to the CPU that controls the entire operation of the mobile terminal for processing and stored in the memory for storing the necessary control data and control program by the mobile terminal. The CPU determines whether the signal is control information of the photographing device. If the signal is control information of the photographing device, the signal is transmitted to the entire operation of the photographing device through the interface (not shown) of the mobile terminal and the photographing device and is responsible for In the processor of the photographing device that performs data communication between the mobile terminals, the processor determines the photographing state of the entire photographing device based on the obtained control parameters and other control data. In the photographic state determined by the control parameter, the CCD camera converts the light image input from the lens into an electrical image signal and supplies it to the Dsp, and then the DSP converts the 4 electrical image signal into a digital signal and converts it. The subsequent digital image signal is supplied to the JPEG device, and the PEG device compresses the digital image signal that is input from the DSP in accordance with an international standard for compressing color still photos. In addition, the digital image signal needs to be converted into a luminance signal γ and a chrominance signal C by the DSP, and the signal is supplied to the camera by the processor through a multiplexer (not shown) between the mobile terminal and the photographing device. The LCD of the device and the encoder of the mobile terminal are further converted by the encoder into the 〇SD of the mobile terminal by converting the luminance signal Y and the chrominance signal c into RGB image signals.
