Embodiment 1

[0095] This embodiment provides an image processing method; the method is applied to a mobile terminal, and the mobile terminal is provided with at least two image acquisition devices, such as cameras; the mobile terminal can be specifically a mobile phone, a tablet computer, etc.; here , first, describe the photosensitive process of the sensor (sensor) in the camera of the mobile terminal, specifically,

[0096] The camera sensor is a two-dimensional matrix composed of photosensitive elements (CCD or CMOS) densely arranged in both horizontal and vertical directions. Figure 4 It is a schematic diagram of the arrangement of the photosensitive elements of the embodiment of the present invention; Figure 4 As shown, the photosensitive elements are arranged in four Bayer modes, and each CCD or CMOS corresponds to a pixel, where R senses red light, G senses green light, and B senses blue light. In the Bayer mode, G is twice as large as R and B. Each CCD or CMOS in the matrix is ​...

Embodiment 2

[0110] This embodiment provides an image processing method; the method is applied to a mobile terminal, and at least two image acquisition devices are set in the mobile terminal. Specifically, the method includes:

[0111] Step 1: The mobile terminal detects a target operation on the image acquisition device; the target operation is used to trigger the image acquisition device to enter a long-exposure framing state;

[0112] In this embodiment, the mobile terminal can set a specific key (such as a virtual key or a physical key), and then enter the long-exposure framing state when the mobile terminal is in the image acquisition state and detects that the user triggers the specific key. Here, since the mobile terminal described in this embodiment is connected or provided with a plurality of image acquisition devices, when the mobile terminal enters the image acquisition state, only a specific image acquisition device can be enabled by default, such as the main image acquisition d...

Embodiment 3

[0121] This embodiment provides an image processing method; the method is applied to a mobile terminal, and at least two image acquisition devices are set in the mobile terminal. Specifically, the method includes:

[0122] Step 1: The mobile terminal detects a target operation on the image acquisition device; the target operation is used to trigger the image acquisition device to enter a long-exposure framing state;

[0123] In this embodiment, the mobile terminal can set a specific key (such as a virtual key or a physical key), and then enter the long-exposure framing state when the mobile terminal is in the image acquisition state and detects that the user triggers the specific key. Here, since the mobile terminal described in this embodiment is connected or provided with a plurality of image acquisition devices, when the mobile terminal enters the image acquisition state, only a specific image acquisition device can be enabled by default, such as the main image acquisition d...

Abstract

The embodiment of the present invention discloses an image processing method, the method comprising: the mobile terminal detects a target operation on the image acquisition device; the target operation is used to trigger the image capture device to enter the long exposure framing state; based on the target operation Trigger at least two image acquisition devices to enter the image acquisition state, and control the at least two image acquisition devices to perform viewfinding operations to obtain at least two viewfinder images; detect each of the image acquisition devices corresponding to the viewfinder operation A luminous flux parameter; a target luminous flux parameter is determined based on the luminous flux parameters corresponding to each of the image acquisition devices, and the target luminous flux parameter is used to perform image processing on the first framing image of the at least two framing images to obtain a long-exposure framing state Under the target framing image, present the target framing image. The invention also discloses a mobile terminal at the same time.

Description

technical field [0001] The present invention relates to electronic technology, in particular to an image processing method and a mobile terminal. Background technique [0002] Long exposure is an exposure method with a slow shutter speed and a long exposure time. The advantage is that it can take pictures of dark scenes more clearly, and it can also take pictures like dreams. The essence of long-exposure photography is to use a long shutter opening time in one shot to obtain more light and create a clearer photo; The single camera in the middle cannot perform long exposure, and thus cannot achieve the long exposure effect similar to that of a SLR camera, which reduces the user experience. Contents of the invention [0003] In view of this, the embodiments of the present invention provide an image processing method and a mobile terminal to solve at least one problem existing in the prior art. [0004] The technical scheme of the embodiment of the present invention is real...
