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, and the background is blurred to present a beautiful visual aesthetic. When shooting a large natural landscape, you will want to take a clear visual effect before and after the scene, and 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 image shooter, for the scene changes, and Unable to be positive 5 200821724 Shi Cui controls the application of the aperture, and often shoots out the photos of this bamboo shoots, 日, 豕冰.

The 1 w20 system of the aperture value and the (4) remainder provides a complex array with the set values S, and: Γ: for the image manipulation unit 26 to benefit from the circle In the eight sets provided by the eight technology system, the different values are provided in the set values, so when the image manipulation heart == is in the 'optical module 241 of the 'optical optical system' and the ==? among the set values The aperture value and the shutter value are changed, so that the secret is taken as the final result of the early 26; 8 200821724 Image with the same depth of field. The setting values provided by the control unit 2ΰ are determined by the full-automatic mode used in the digital camera or the aperture h-square. In the fully automatic mode, it is first to measure the light and “measure the ambient light source, and automatically determine the aperture value used by the core group 241 according to the metering result. As for the light priority mode, the user can The aperture of the shirt is 241, and the aperture value is 241. After the aperture value is determined, the exposure value (Exp〇sureValue; _) = aperture EV value + shutter speed EV value is used to know the exposure EV value and aperture. After the EV value, the shutter speed value can be calculated, and the EV value corresponding to the aperture value and the shutter value can be obtained by querying the EV conversion table, and the EV conversion table belongs to the knowledge in the field, and is not used here. The following is a flow chart of a preferred embodiment of the method for photographing the depth of field of the present invention. The related system architecture ~ and referring to the second figure, the depth of field surrounding shooting method The execution steps are as follows: First, when the user inputs a depth of field bracketing signal through the input unit 22 to start image capturing (S301), when the image capturing unit 26 performs shooting; first, the imaging optical system 24 is transmitted. The photometric module 243 is in the middle of the measurement (S303); then the first set of values combined by the aperture value and the shutter value is provided by the control unit 20 (S305), and the aperture value in the first set of values is It can be determined by the full-automatic mode or the aperture-priority operation mode, and the shutter value in the first set of set values is obtained by knowing the photometric value in the photometric result and the first set value, and is derived by using the above formula; The unit 20 further generates a complex array second set value according to the aperture value in the first set of set values (S307), wherein the aperture value in the second set value is obtained by adding or subtracting the aperture value in the first set value. The aperture value obtained by the second aperture is different from that of the second set value, and the shutter value in the second set value is based on the photometric result and the aperture value in the second set value, and then According to the foregoing formula, the final image capturing unit % continuously takes a plurality of photos according to the first setting value and the contents of the second setting values (S309); and the storage unit 28 stores the shooting knot. (S311); and displaying the shooting result by the display unit 3〇 13 13) Γ i wherein the step S3G1 in the step S3G1, the input of the depth of field surrounding the signal can be implemented by pressing the button, and the button The New Zealand language "10% and a half on time to f, and press the button to control the action ^. Therefore, the start-up image shooting described in the above step S3Q1 is to perform the metering operation of the photometry module 243 in a half-pressing manner, and then the control unit provides the set value according to the metering knot. The upper = middle image capturing unit 26 continuously takes a plurality of photos and takes a picture when the button is pressed at all L. The input unit 22 is in accordance with the financial statement, but it is not limited thereto. There may be other equal embodiments. The J value has two specifications, 65, 9Q, etc., and each aperture value is adjacent to the second system: two: 柊45 One aperture value, assuming that the aperture value after the original (3) plus or minus-square is F2. 8, and if ^ is ?4, the increase is F5.6. On the contrary, the aperture value after reducing one frame is thus utilized. The photo provided by the present invention can be as shown in the fourth figure: ^ 0 is taken in plural different depth of field 2 is used for photographing - the subject 11, and The medium-brightness surrounding shooting device is a three-dimensional continuous shooting device to obtain image images of the image depths 3 of the depth of field D1 and D2 of different depth of field devices 2, and the % of the images makes the image of the 10,217,224 of the object 11 clear and The image of the background 1) 3 shows that the 3 shirts are blurred, and the depth of field is the clear shot.
