Long exposure method and camera device

Abstract

The invention relates to a long exposure method and a camera device. The problems that only a standing preview screen is displayed and a display function is single, which are caused by the fact that a photosensitive device is in consistent exposure and no longer outputs an image when the long exposure function of the existing camera device is used to take pictures, are solved. The method provided by the invention comprises the steps that when the camera device is used to take pictures, the current exposure time is monitored in real time, and whether total exposure time is preset is determined; if so, the camera device determines current remaining exposure time according to the monitored current exposure time and the total exposure time, and displays the current remaining exposure time in a countdown manner; and if not, the camera device displays the monitored current exposure time in a positive timing manner. According to the invention, related exposure time is determined and displayed according to the monitored current exposure time; the standing preview screen is displayed; related exposure time is displayed; and a display function of the camera device is increased.

Description

technical field [0001] The invention relates to the technical field of digital imaging, that is, image processing, in particular to an ultra-long exposure method and photographing equipment. Background technique [0002] Nowadays, high-end smart phone cameras, digital cameras and other camera equipment generally have the function of ultra-long exposure. The so-called ultra-long exposure function is to use long-time exposure technology to create amazing space-time images. Using ultra-long exposure technology, the trajectory of moving objects can be connected into a line, giving people a visual effect of movement. For example, using a mobile phone with ultra-long exposure function to take pictures can achieve heavy traffic at night and light painting effects, etc., but in In practical applications, since the photosensitive device is continuously exposed and no longer outputs images, only a static preview screen can be displayed, and the display function is relatively simple, w...

Problems solved by technology

[0004] The present invention provides an ultra-long exposure method and photographing equipment, which are used to solve the problem that when taking pictures with the ultra-long exposure function of the photographing equipment at present, due to the continuous exposure of the photosensitive device, the image is no longer output, and the preview screen also stops, which is easy Issue that gives users the false impression that the camera device is unresponsive
