Problems solved by technology

But in many cases, when all object distances are taken from far and near multiple focus shooting, the shooting image produced by the object distance that does not exist in the image to be shot is invalid for the user
When this method is adopted, it will not only result in invalid shooting images at many object distances, but also increase the number of shooting times, which not only takes a long time to shoot, but also requires high storage space for the device, which increases the cost of the device and is not conducive to use.

Embodiment Construction

[0046] Figure 1a Shown is a functional block diagram of an embodiment of the image capture device 10 . The image capturing device 10 may be a digital camera, a mobile phone with a built-in camera, or other devices capable of image capturing. In this embodiment, the image capture device 10 includes a pre-capture module 101 , a conversion module 103 , an area division module 105 , a distance measurement module 107 , a calculation module 109 and a real-capture module 111 . Wherein, the pre-shooting module 101 is used for initial framing of the image; the conversion module 103 is used for converting the initial framing image into a gray-scale image; the area division module 105 is used for dividing the gray-scale image into a plurality of sub-regions; It is used to measure and calculate the object distance set of each sub-region, and integrate it into the entire image object distance set; the calculation module 109 is used to calculate the shooting conditions that make multiple d...

Abstract

An image shooting device includes a preshooting module, a conversion module, a region division module, a range finding module, a calculation module and an actual shooting module. The preshooting module is used for initial framing of an image; the conversion module is used for converting an initial framing image to a gray scale image; the region division module is used for dividing the gray scale image into a plurality of subregions; the range finding module is used for calculating an object distance set of each subregion, and integrating into an object distance set of the overall image; the calculation module is used for calculating shooting conditions which enable a plurality of depth of field distances to cover the object distance set of the overall image; and the actual shooting module is used for forming an image array by performing multiple times of focusing and shooting on the image according to the shooting conditions. The invention also provides an image shooting method. The image shooting device and method provided by the invention can reduce shooting times required in shooting, save time for shooting, save equipment storage space, and reduce equipment costs.

Description

technical field [0001] The present invention relates to the field of image shooting, in particular to an image shooting device and method for multiple focus shooting. Background technique [0002] At present, with the continuous development of image shooting technology, it is more and more common to use a digital camera or a built-in camera of a mobile phone for shooting. Most of the current digital cameras or mobile phone built-in cameras use auto-focus technology. Although it brings convenience when using it, but because it can only focus once, it is often found that the desired part is out of focus after taking pictures. A situation where the image is unclear or unrecognizable. Especially when the object to be photographed has different object distances between far and near, the image in some areas will often be blurred. [0003] In view of this situation, the existing technology adopts multiple focus shooting methods, and through infrared automatic focusing or contrast...
