Starting method for mobile terminal camera

Abstract

The invention discloses a starting method for a mobile terminal camera. The starting method for the mobile terminal camera includes the following steps: (1) the camera is started, and a start mode is read; (2) whether the start mode is a fast mode is judged; (3) if the start mode is the fast mode, a bottom driver starts the camera in the fast mode, and if not, the bottom driver is informed to start the camera in a common mode; (4), a staring process is finished, and normal shooting is carried out; (5) the camera is exited; (6) whether an exit mode is a fast mode is judged; (7) if the exit mode is the fast mode, the bottom driver exits the camera in the fast mode, the camera enters into a standby mode, if not, the bottom driver exits the camera in a normal mode, and the camera is turned off; and (8) the whole process is finished. By means of the starting method for the mobile terminal camera, camera starting is accelerated, and a user can take a candid photograph conveniently.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a quick start method for cameras of mobile terminals such as mobile phones and digital cameras. Background technique [0002] The current mobile phones are basically equipped with cameras, and the functions and effects of taking pictures are getting closer and closer to those of some digital cameras. When the mobile phone and digital camera turn on the camera, the main control chip needs to send a large number of initial sequences to the ISP chip through a certain bus (usually the I2C bus), and then the ISP chip internally initializes these sequences, and continues to send them from the main control chip after the initialization is completed. The set parameters are sent to the ISP chip, and then the data comes out from the camera. To complete such a process, it takes a long time to open the underlying driver of the camera, usually three seconds, four seconds or longer. Some...

Problems solved by technology

Some models of cameras need to add some time to achieve the best effect by turning on the detection of surrounding light sources, resulting in not very good image effects when the camera is just turned on

If the user is in a state where the camera is not turned on, it is necessary to turn on the camera again when encountering a scene to be captured. This delay of a few seconds may sometimes cause the capture to fail.

In addition, when traveling and visiting, it is often necessary to take some photos intermittently. For example, if you walk a few steps, there is something you want to capture. If you keep the terminal device turned on during this intermittent time, it will be very expensive. The battery level of the device

And if it is turned off after each shot, it needs to be restarted and re-entered and waited for a few seconds when taking a photo again, which often makes the user miss the opportunity to take pictures of the beautiful scenery
