Embodiment Construction

[0048] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0049] A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, "module" and "component" may be mixedly used.

[0050] Mobile terminals may be implemented in various forms. For example, terminals described in the present invention may include devices such as mobile phones, smart phones, notebook computers, digital broadcast receivers, PDAs (Personal Digital Assistants), PADs (Tablet Computers), PMPs (Portable Multimedia Players), navigation devices, etc. mobile terminals and fixed terminals such as digital TVs, desktop computers, etc. In...

Abstract

The invention discloses a device and a method for virtually processing a depth image. The device comprises an obtaining module used for obtaining an aperture value, a focal length, a focusing distance and a permissible confusion circle diameter; a calculating module used for calculating a field depth range according to the obtained aperture value, focal length, focusing distance and permissible confusion circle diameter; a determining module used for obtaining object distances to a focus and determining virtual degrees corresponding to the different object distances according to the obtained object distances to the focus, aperture value and focusing distance; a correction module used for correcting radiuses corresponding to Gaussian blur according to the determined virtual degrees corresponding to the different object distances; and a fuzzy processing module which is used for carrying out fuzzy processing on pixels of the depth image requiring virtual processing and out of the field depth range according to the corrected radiuses corresponding to the Gaussian blur and is used for shooting. According to the technical scheme provided by the invention, the shooting effect is improved without changing a physical hardware structure of an existing mobile terminal.

Description

technical field [0001] The invention relates to image processing technology, in particular to a device and method for blurring and processing depth images. Background technique [0002] Existing ordinary digital devices (such as mobile terminals or different cameras) cannot compare with SLR cameras on the photosensitive element, and cannot shoot background blur effects with a clear sense of hierarchy. This is because the physical hardware structure of mobile terminals is difficult to make It is similar to the physical hardware structure of a SLR camera. In addition, the existing background blur model algorithm does not make full use of the imaging model of the SLR, the degree of background blur is unreal, and the physical background blur effect of the SLR is not as good. [0003] Therefore, how to achieve a picture with the same shooting effect as that of a single-lens reflex camera without changing the physical hardware structure of the existing mobile terminal has become ...
