Description of the invention: [Technical field to which the invention pertains] The present invention relates to the fact that the surface is loose, and the _ is related to the kind of information that can provide a light-hearted message, and whether the image of the self-touch is clear and miscellaneous The method of weaving and weaving. [Prior Art] Press, with the advancement of technology, the electronic camera device has been bent, gradually replacing the traditional camera device. For example, the device has gradually replaced the transmission machine. The first is that the current digital machine can be displayed by liquid crystal display 11 So that people can __ watch the photos at any time, and can directly process the images into the domain position when taking pictures: all the branches are greatly increased, and the size of the camera is smaller than that of the traditional camera, making the digital position more complicated. The replacement of traditional cameras by the city called has become a trend. The digital camera is developing with the technology, and the pixels it photographs are also upgraded to the mega-pixels. The image of this image will not be distorted during the amplification process, but the door of phase 3 A plain & image space occupied by the image is larger, so it is necessary to have a larger storage space. The image of another pixel is also a problem. This is caused by the user after the knife is photographed. The picture of the picture will be displayed on the LCD, and the size of the LCD is about ^, so the user will have a slight shake when shooting. However, because the resolution of the liquid crystal display is not enough, the current image displayed on the digital phase is clear, so the actual captured image is separated from the tree displayed on the (4) display. When the time is passed, the filming of the filming is shown as _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Time and frequency to accumulate, while still For more experienced operators to guide, so the time and money for the initial users are _ 士 4 口 ^ '111 How to develop a method in the digital camera to determine whether the image is β or not, It is extremely needed by the public. The present invention is directed to the problem of the description of the invention, and the method of image blur detection of the photographing device is proposed to effectively overcome the trouble of the transfer camera and the device. _ [Summary of the Invention] The main purpose of the present invention is to provide an image blur detection method for a mask device, by comparing a clear image in the focus phase with the last captured image, thereby determining that the last film image is Clear or fuzzy, and inform the system to capture the state of the image, so that the user can better image the image, which will improve the efficiency and reduce the error. This "Mr. Another Purpose" is to provide an image-detection method for a photographic device, which can prompt the user to make relevant shooting suggestions after the user takes a picture, so that the user can quickly accumulate the photography experience. The re-purpose of the present invention provides a method for image reshaping, which makes the digital camera more valuable and diverse. According to this (4) '--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The electronic camera device receives the complex image, calculates the sharpness of each captured image, and compares one of the sharpest contrast images, and then compares the image with the image and determines whether it is the same—scene: if , the comparison is to "the sharpness of the image of the spot to judge whether the image is clear or difficult; if not, compare the specific image with the number of images in all the touch images to find the sharpest image. A specific image is used to make the above-mentioned sharpness comparison to judge whether the image is clear or blurred. The details of the present invention, the technical content, and the features thereof are more easily understood by the detailed description of the specific embodiments in conjunction with the accompanying drawings. The effect achieved is φ. [Embodiment] The present invention relates to an image blur detection method for a photographic apparatus, which is manufactured on an electrophotographic apparatus, and the electronic photographic apparatus is A camera, mobile phone or camera that captures the image and instantly determines the clarity of the captured image and informs the user of the condition of the captured image. This allows the manufacturer to be more efficient in performing the image. It is also better to grasp the quality of the captured image. The reading device is an embodiment. The digital camera has a liquid crystal, and the digital camera has a half-press function. This half-pressing shutter can make the digital camera focus first. For the method of the present invention, please refer to the first figure. First, in the first step, during the focusing phase, the image is captured by the electronic camera, and then the step S12 is performed to calculate the sharpness of each captured image. Compare the captured image with the highest definition and define it as a control image. The definition here refers to the red (8), green (6), blue (8) and grayscale values in the alizarin. The sum of the pixels of one or a combination thereof is calculated as: image sharpness force - where AP is all pixels in the image (AU pixels), and in this embodiment In the calculation formula, 1300876 is calculated by using the gray scale value (Gray). Of course, other targets can be explained, such as the above red (8) 'green (G), blue (8), etc., and (i, D is the calculation time) Then proceed to step S14, and compare the contrast image with the captured image to compare the two images. If the image is the same scene, please refer to the two images and the third image. The flow in the paste is explained. First, the step is performed. In the control image and the captured image, the designated area is 1G'. The area of the area is between the control image and the face-to-face of the captured image, and then step S18 is performed, which is to be analyzed. The corresponding control image and the corresponding image of the captured image are simultaneously divided into _block 12, such as the third _, followed by the step side, using the above formula α rain this area 1G_ per _2 male average scale The average value of the image and the captured image is divided into counties V1 and V2, and the average difference value (Dif〇) is calculated according to the following formula: \V2-Vll

Compared with the judgment value, the judgment value is between 3 (10), and the optimal range is between _2〇% and 2〇%. If the average difference (6) is less than the cutoff value, it is judged to be the same scene. Otherwise, it is a different scene. In the following, different steps are performed in the same scene and different scene situations. First, if the comparison image and the captured image are the same scene, please refer to the fourth figure, and perform the step micro, using the above formula (1) respectively.
