Embodiment 1

[0064] 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. like figure 1 As shown, the method includes:

[0065] Step 110, acquire the tracking focus object selected by the user in the photo preview interface.

[0066] In this embodiment, the photo preview interface refers to an interface used to display images captured by the camera in the display interface when the smart terminal is in the photo preview state. 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 camera function. The photo preview state refers to the state in which the photographed image can be previewed through the photo preview interface after the photo function of the smart termi...

Embodiment 2

[0089] figure 2It is a flowchart of a photographing processing method provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. In this embodiment, obtaining the tracking focus object selected by the user in the photo preview interface is specifically: according to the user's selection of the set screen position in the photo preview interface, obtaining the target screen pixel coordinates corresponding to the set screen position ; According to the corresponding relationship between the screen resolution of the photo preview interface and the image resolution of the photo preview image, obtain the target image pixel coordinates corresponding to the target screen pixel coordinates in the photo preview image; The photographing object corresponding to the pixel coordinates of the target image in the photographing preview image is determined as the tracking focus object selected by the user. refer to figure ...

Embodiment 3

[0107] 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, acquiring the image information of the tracking focus object in the depth map generated in the photo preview state specifically includes: acquiring the target image pixel corresponding to the pixel coordinates of the target image; The depth of field information corresponding to the pixel of the target image determines the photographing distance from the tracking focus object to the camera lens, wherein the depth of field information includes the distance information between the subject associated with the image pixel and the camera lens ; In the depth of field map, the difference between the distance information and the photographing distance satisfies the set threshold condition of the image pixel and the target image pixel into the target pixel group; the ta...

Abstract

The embodiment of the invention discloses a photographic processing method and device and relates to the technical field of image processing. The photographic processing method comprises the following steps: acquiring a tracking focusing object selected by a user in a photographing preview interface; in a field depth picture generated in a photographing preview state, acquiring image information of the tracking focusing object, wherein the field depth picture corresponds to the photographing preview image displayed in the photographing preview interface; and when the photographing preview image displayed in the photographing preview interface is detected to be changed, tracking and focusing the changed photographing preview image in real time according to the image information of the tracking focusing object. By adopting the technical scheme of the embodiment of the invention, when the photographing preview image is changed, an object expected to be photographed by the user can still be accurately tracked and focused in real time, and usage experience of the user is enhanced.

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 focus 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: after the smart terminal finishes focusing on the picture taken by the camera, the displacement of the subject changes, or the movement of the smart terminal cau...
