Problems solved by technology

However, it is unavoidable that the user may have different degrees of shaking when shooting. If the user shakes the hand slightly at the moment of shooting, the image data obtained at the moment of shooting will be blurred to a certain extent. The acquired image data is used as the final captured image, which will cause the image captured this time to be unclear and seriously affect the user experience

Embodiment 1

[0020] figure 1 A flow chart of the method for acquiring a captured image provided in Embodiment 1 of the present invention is given. The method of this embodiment can be executed by a device for acquiring a captured image, which can be implemented by means of hardware and / or software. The device It can be set inside the terminal as a part of the terminal with the camera function.

[0021] Such as figure 1 As shown, the method for acquiring captured images provided in this embodiment specifically includes the following steps:

[0022] Step 101, after detecting a shutter trigger event, acquire multiple currently stored preview images.

[0023] In this embodiment, multiple currently stored preview images are acquired after the terminal detects a shutter trigger event, wherein the terminal may be a mobile phone, a notebook, a PAD smart terminal, a tablet computer, a digital camera, and the like.

[0024] The stored multiple preview images include at least one preview image cap...

Embodiment 2

[0030] figure 2 A flow chart of the method for acquiring captured images provided by Embodiment 2 of the present invention is given. This embodiment is optimized on the basis of the above embodiments. In this embodiment, according to the brightness difference of each pair of adjacent pixel points in the preset area corresponding to each preview image in the plurality of preview images, from Selecting a preview image with the highest definition among the plurality of preview images as the target image for display is specifically optimized as follows: each of the plurality of preview images is respectively used as a current image, and the current images are sequentially selected The pixel in the current pixel is used as the current pixel, and the difference between the brightness of the current pixel and the brightness of the adjacent pixel is calculated, and when the difference is greater than the preset threshold, the corresponding counter of the current image is increased by...

Embodiment 3

[0047] Figure 5 A schematic structural diagram of an image acquisition device provided in Embodiment 3 of the present invention is given. Such as Figure 5 As shown, the device for acquiring captured images provided in this embodiment includes: a preview image acquiring unit 51 and a target image selecting unit 52 . Wherein, the preview image acquiring unit 51 is configured to acquire a plurality of currently stored preview images after a shutter trigger event is detected; According to the brightness difference value of each pair of adjacent pixel points in the preset area corresponding to the image, a preview image with the highest definition is selected from the plurality of preview images as the target image for display.

[0048] Further, the target image selection unit 52 includes:

[0049] The counter calculation subunit is used to use each preview image in the plurality of preview images as a current image, sequentially select the pixels in the current image as the c...

Abstract

The embodiment of the invention discloses a method and device for acquiring a shot image. The method comprises the following steps: after a shutter trigger event is detected, acquiring a plurality of currently-stored preview images; and selecting a preview image with highest definition from the plurality of preview images according to a brightness difference value between every pair of adjacent pixel points in a preset area corresponding to each preview image in the plurality of preview images to serve as a target image to be displayed. Through adoption of the technical scheme provided by the embodiment of the invention, the technical problem of display image fuzziness since a preview image captured at a shutter pressing moment is still taken as the target image to be displayed even vibration is generated at a moment when a user presses down the shutter in the prior art is solved; an existing shot image acquisition technology is optimized; and the definition of the shot image is increased.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data processing, and in particular, to a method and device for acquiring captured images. Background technique [0002] With the continuous development of electronic technology, digital camera equipment (for example, digital camera or mobile phone with digital camera, etc.) has penetrated into thousands of households, and has become an indispensable tool for everyone to record beautiful natural scenery and engrave the wonderful moments of life. Users have higher and higher requirements for shooting, not only needing fast shooting speed, but also needing clearer images. [0003] Zero-delay snapshot, simply put, is to save the closest few frames of the previewed image to the memory in real time. When the user presses the shutter, the system will directly read the captured image at that moment in the cache. One frame of image data forms the final image displayed on the camera device, s...
