Embodiment 1

[0036] refer to figure 2 , showing a flow chart of the steps of an embodiment of a method for taking photos of the present invention, which is applied to a mobile terminal, and the mobile terminal includes a sensor sensor of a camera, an image processor ISP and a digital signal processor DSP, and the DSP is connected to Between the sensor and ISP.

[0037] It should be noted that the embodiment of the present invention adds a DSP (Digital Signal Processing, digital signal processor) on the basis of the hardware framework of the original mobile terminal, so that the image data can be processed before entering the ISP (Image Signal Processing, image signal processing). Realize more image processing functions and improve the image quality of image data. Specifically, the camera module of the camera has a sensor (sensor), and the mobile terminal is provided with a DSP connected to the sensor of the camera and the ISP. Usually, the ISP is used in the mobile terminal as the senso...

Embodiment 2

[0053] refer to image 3 , showing a flow chart of the steps of an embodiment of a method for taking photos of the present invention, which is applied to a mobile terminal, and the mobile terminal includes a sensor sensor of a camera, an image processor ISP and a digital signal processor DSP, and the DSP is connected to Between the sensor and the ISP, the method may specifically include the following steps:

[0054] Step 201, receiving a request to enter the camera application, controlling the initialization of the DSP; and controlling the initialization of the sensor and the ISP at the same time.

[0055] In the embodiment of the present invention, the DSP can detect whether there is an action of the user clicking the camera application through hardware interrupts, etc., and when the action is detected, the DSP starts working immediately to achieve the purpose of parallelism, and does not need to wait until the application is started to complete.

[0056] In the embodiment o...

Embodiment 3

[0122] refer to Image 6 , shows a structural block diagram of an embodiment of a mobile terminal of the present invention, the mobile terminal includes a sensor of a camera, an image processor ISP and a digital signal processor DSP, the DSP is connected between the sensor and the ISP, The mobile terminal may specifically include the following modules:

[0123] The initial image data receiving module 301 is used to receive the initial image data output by the sensor when receiving a request to enter the camera application;

[0124] The intermediate image data obtaining module 302 is used for the DSP to perform image processing on the initial image data to obtain intermediate image data;

[0125] The preview image data obtaining module 303 is used for the ISP to perform image processing on the intermediate image data to obtain preview image data;

[0126] The first-time photographing module 304 is used for the ISP to generate photographed image data by using the preview image...

Abstract

The embodiment of the invention provides a shooting method and a mobile terminal. The mobile terminal comprises a sensor of a camera, an image processor ISP and a digital signal processor DSP, wherein the DSP is connected between the sensor and the ISP, and the method comprises the following steps: when a request of entering a camera application is received, the DSP receives initial image data output by the sensor; the DSP performs image processing on the initial image data to obtain intermediate image data; the ISP performs image processing on the intermediate image data to obtain preview image data; and the ISP generates shooting image data by using the preview image data to accomplish once shooting. By application of the shooting method provided by the embodiment of the invention, the camera starting time can be shortened based on the newly added DSP.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for taking pictures and a mobile terminal. Background technique [0002] With the increasing application of smart mobile terminals such as mobile phones, the performance of camera photosensitive chips continues to improve, coupled with the portability of mobile terminals, cameras on mobile terminals often replace traditional cameras, and even the role of SLR cameras. Camera applications (APP) are becoming more and more popular. Sometimes when encountering some wonderful moments, users very much hope that they can quickly capture them, if they can quickly open the camera application and capture them immediately. [0003] refer to figure 1 , the camera application needs to involve sensor (sensor / photosensitive chip) and ISP (Image Signal Processing, image signal processor). The general process of the current camera startup process is: [0004] 1. Click the camera...
