Description of the Invention: [Technical Field] The present invention relates to a photographing method and apparatus, and more particularly to a depth-of-field bracketing method and apparatus for adjusting aperture variation. [Prior Art] For image capturing, the focusing operation performed by the shooting is to let the camera, such as a digital camera, camera, mobile phone, etc., focus on the subject being photographed, as shown in the first figure, the digital camera. 1 After focusing, the focus falls on the subject 11, and the captured image will appear in a clearly visible range at a distance from the front and back of the subject 11, which is the Depth of field DO, also That is to say, the image of the subject 11 on the image will be the clearest part. However, the position of the subject before and after the subject 11 will be blurred because it is not in focus, and the blurring of the subject from the focus will be more serious. Therefore, the background object 13 in the first figure is not in the range of the depth of field DO which can be clearly imaged, so the background object 13 will have a blurred image effect on the image. Different scenes are shallow and shallow, and there are occasions suitable for shooting. For example, shallow depth of field is usually used when shooting portraits, so that the subject of the character can be highlighted as the main subject, and the background is blurred to present a beautiful visual aesthetic. In the case of a large natural scenery, you will want to take a clear visual effect before and after the background. The depth of field used for shooting must be as long as possible. Although the depth of field can be determined by the aperture' and the existing high-end digital cameras provide full manual, aperture priority, shutter priority, etc., but for the average video shooter, the depth of the scene changes 'and It is impossible to control the application of the aperture in the 1320869, and often the inappropriate depth of field is taken. In view of this, the present invention proposes a method of enclosing the depth of field - the image is known. The above is missing. The technical problem to be solved is to provide a method and a device for reducing the aperture. By automatically controlling the change of the aperture, the process towel surrounding the beat uses a non-aperture value, and allows the user to connect twice and facilitate the continuous shooting result. In order to solve the above technical problem, in accordance with the present invention, a method for enclosing a depth of field enveloping image capture method includes: providing a set value of a combined value of a combined array of values for an image The capture unit performs image capture, and the aperture values in these set values are used with different values. The image capture unit according to the combination of these set values is used to capture a plurality of images. In order to solve the above technical problem, another method according to the present invention provides a depth of field bracketing method when an image capturing unit performs First, a first set value is firstly provided by metering, and the first set value is combined by the aperture value and the shutter value; and then the second set of set values of the complex array is generated according to the aperture value in the first set of set values, The second set of values is also combined by the aperture value and the shutter value, and the aperture values in each of the second set values are different from each other, and the aperture value in each of the second set values is the first level • the set value The aperture value is obtained by adding or subtracting at least one aperture; and the last image capturing unit respectively takes a plurality of consecutive photos according to the first set value and the contents of the second set of settings. 6 In order to solve the above technique The problem is that according to the present disclosure, a depth of field bracketing device is provided, including: ~, a time scheme, an optical system, an image capturing unit, a control unit, and a camera ί. With the input-depth of field surrounded by the shooting element, when receiving the depth of field packet _ reduction, provide = ΓΓ and control the set value of the single value combination, for the image of the sofa unit 3 = value and shutter and shutter value changes, and The aperture value in the value of the == value is provided, and the storage unit is used to store the image. The value of the circle taken by the caller is not to use the depth of field of the present invention to surround the shooting result. It uses a film like 'Film, which is the same as the aperture value that allows the user to get the same result from the continuous shooting result. It is effective. Choose a satisfactory depth of field to capture the above overview and the following detailed description. The present invention is for the purpose of achieving the intended purpose, and 'the other purpose and mode of the present invention, the hand 4 and the drawings are explained. ·, 'will be explained in the following [implementation] Means] The present invention proposes a kind of depth of field enveloping shooting technology, the aperture of the lens can be obtained, and the principle of profit is deep, so the present invention utilizes this principle, and a small depth of field value can be obtained to obtain different depth of field shooting.
