Problems solved by technology

However, in the prior art, the interval time for continuous image data collection is fixed and cannot be changed according to the specific situation, and different shooting devices process data at different speeds, and the same shooting device processes data at different speeds under different situations
Therefore, if the interval time is set too long, the real-time performance of the display exposure effect will be insufficient, which will affect the user experience; if the interval time is set too short, it may exceed the computing power of the shooting device and cause data loss

[0040] see figure 1 , propose the first embodiment of the slow shutter shooting method of the present invention, the slow shutter shooting method includes the following steps:

[0041] Step S101: After shooting starts, continuously collect image data to the buffer module, and adjust the acquisition speed in real time according to the remaining space of the buffer module

[0042] When the user presses the shutter button or triggers the virtual shutter button, the shooting device starts to shoot, and continuously collects image data to the buffer module. During the process of collecting image data, it is judged in real time whether the remaining space of the cache module reaches a preset value, and if so, the collection speed is adjusted to the preset speed.

[0043] For example, when the photographing device detects that the remaining space of the cache module is above 50%, the image data is collected at the maximum speed; when it is detected that the remaining space of the ca...

[0053] see figure 2 , propose the second embodiment of the slow shutter shooting method of the present invention, the slow shutter shooting method includes the following steps:

[0054] Step S201: After the shooting starts, exposing the picture captured in the viewfinder window

[0055] Step S202: Continuously generate images according to the image data

[0056] Step S203: Display the images one by one in the viewfinder window, and the images generated later cover the images generated earlier

[0057] Steps S201-S203 in this embodiment are the same as steps S101-S103 in the first embodiment, and will not be repeated here.

[0058] Step S204: After the shooting ends, display all the generated images in the viewfinder window

[0059] After the user releases the B door or presses the T door again to end the entire shooting process, the shooting device will tile all the generated images in the viewfinder window for display, so that the exposure effect of the photo at different...

Abstract

The invention discloses a low-speed shutter shooting method and device. The low-speed shutter shooting method includes the steps of in the shooting process, continuously collecting image data into a buffering module, adjusting the collecting speed according to free space of the buffering module, continuously generating images according to the image data, and displaying the images in a framing window. In this way, the processing capacity of the shooting device is used to the maximum degree, data losses caused by the over-high collecting speed can be avoided, meanwhile, the display instantaneity of the exposure effects is improved, and the user experience is improved. After exposure is finished, as a user can select a plurality of pictures with the different exposure effects from the framing window, the user can obtain the multiple pictures with the various exposure effects through one-time shooting, and the user experience is further improved.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to a slow shutter shooting method and a shooting device. Background technique [0002] The shutter speed in a shooting device indicates how long the shutter remains open when the camera is shooting. The shutter speed and the aperture size of the lens (also called the focal length ratio) together determine the amount of light reaching the film or sensor, or exposure. The faster the shutter speed, the shorter the exposure time and the less exposure, but the clearer images of moving objects can be presented on the film. The slower the shutter speed, the longer the exposure time and the more exposure, but the images of moving objects on the film will appear blurred. Usually, taking photos with a shutter speed below 1 / 30 second is called slow shutter shooting. Shooting at a slow shutter speed can result in special or artistic photos. [0003] In the prior art, some shooting devices...
