Embodiment 1

[0085] figure 1 It is a flow chart of a photographing processing method provided in Embodiment 1 of the present invention. The method can be executed by a photographing processing device, wherein the device can be implemented by software and / or hardware, and can generally be integrated into a smart terminal. Such as figure 1 As shown, the method includes:

[0086] Step 110: Identify at least one reference focus object in the depth map generated in the photo preview state, wherein the depth map corresponds to the photo preview image displayed in the photo preview interface.

[0087] In this embodiment, the depth map can be acquired through the camera of the smart terminal. Wherein, the smart terminal may be a smart device held by a user such as a smart phone, a tablet computer, or a camera and having a shooting function.

[0088] Specifically, the depth of field refers to the distance range of an object measured by the axis of the imager that can obtain a clear image at the ...

In this embodiment, obtaining the selected target focus object specifically includes: in the photographing preview interface, providing a calibration prompt for the identified reference focus object; acquiring the target focus object selected by the user according to the calibration prompt. refer to Figure 2a , the method provided in this embodiment specifically includes:

[0110] Step 210: Identify at least one reference focus object in the depth map generated in the photo preview state, wherein the depth map corresponds to the photo preview image displayed in the photo preview interface.

[0111] Step 220 , in the photographing preview interface, provide a calibration prompt for the identified reference focus object.

[0112] In this embodiment, considering the selection in...

Embodiment 3

[0158] image 3 It is a flow chart of a photographing processing method provided by Embodiment 3 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. In this embodiment, identifying at least one reference focus object in the depth-of-field map generated in the photographing preview state is specifically: acquiring the depth-of-field information of each image pixel in the depth-of-field map, wherein the depth-of-field information includes image pixel points The distance information between the associated subject and the camera lens; the image pixels whose difference between the distance information meets the set threshold condition are grouped into the same pixel group; the images with continuous image pixel coordinates in each pixel group Pixels are identified as reference focus objects.

[0159] At the same time, focusing on the photo preview image according to the target focusing object specifically includes: determining th...

Abstract

The embodiment of the invention discloses a photographic processing method and apparatus, and relates to the technical field of image processing. The photographic processing method comprises the steps of identifying at least one referential focusing object in a depth map generated under a photo preview state, wherein the depth map corresponds to a photo preview image displayed in the photo preview interface; acquiring a selected target focusing object; and focusing the photo preview image according to the target focusing object. A target focusing object is accurately focused according to the target focusing object selected by a user in the at least one referential focusing object, so that the final focusing result is closer to the actual focusing demand of the user. Photographic technology of a conventional smart terminal is optimized, and the user experience is improved.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular, to a photographing processing method and device. Background technique [0002] With the development of Internet, computer and communication technologies, the functions of smart terminals such as smart phones are becoming more and more powerful, and the user's dependence on smart terminals is also increasing, such as querying weather forecasts and taking photos. [0003] Usually, when the user uses the smart terminal to shoot, the smart terminal will automatically complete the focusing according to the picture captured by the camera, and display the focused preview picture on the display interface. [0004] However, in the process of realizing the present invention, the inventor found that the defect of the present invention is that: after the smart terminal finishes auto-focusing on the picture captured by the camera, the auto-focused picture may not be the...
