Image capture device and method

Abstract

An image shooting device includes a pre-shooting module, a conversion module, an area division module, a distance measuring module, a calculation module and a real shooting module. The pre-shooting module is used for initial framing of the image; the conversion module is used for converting the initial framing image into a gray-scale image; the area division module is used for dividing the gray-scale image into multiple sub-regions; the ranging module is used for measuring the distance of each sub-region The object distance set is integrated into the entire image object distance set; the calculation module is used to calculate the shooting conditions that make multiple depth of field distances cover the entire image object distance set; the actual shooting module is used to perform multiple focus shots on the image according to the shooting conditions to form image array. The invention also provides an image shooting method. The image shooting device and method provided by the present invention can reduce the number of shootings required for shooting, save the time used for shooting, save the storage space of the device, and reduce the cost of the device.

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...

AI Technical Summary

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.
