Picture displaying method and apparatus

Abstract

The invention discloses a picture displaying method and apparatus. The picture displaying method includes the steps: acquiring the environmental state of the monitored scene by means of a camera terminal; according to the obtained environmental state, adjusting the brightness gain of the picture of the monitored scene to achieve the target brightness; and according to the magnitude of the gain, controlling the value of the shutter. Based on the hardware condition of the current camera terminal, without sacrificing the angle of visual field, according to changes of the brightness of the ambient light or changes of the monitored object, the picture displaying method and apparatus can adjust the gain and the shutter so as to change the exposure time to reduce the smearing phenomenon of the displayed picture.

Description

technical field [0001] The present invention relates to the technical field of photography, in particular to a method and device for displaying images. Background technique [0002] Network camera (IP Camera) is a new generation of camera produced by the combination of traditional camera and network technology. In addition to all the image capture functions of general traditional cameras, it also has a built-in digital compression controller and a WEB-based operating system. After the video data is compressed and encrypted, it is sent to the end user through the LAN, Internet or wireless network. [0003] For current IP Camera devices, for high-resolution products, due to the limitation of back-end coding capabilities, they can only output at low frame rates. However, after the frame rate is reduced, smearing will occur when shooting objects in motion. If the frame rate is increased to solve the problem of smearing, the resolution needs to be reduced, and the output image s...

Problems solved by technology

[0003] For current IP Camera devices, for high-resolution products, due to the limitation of back-end coding capabilities, they can only output at low frame rates. However, after the frame rate is reduced, smearing will occur when shooting objects in motion. If the frame rate is increased to solve the problem of smearing, the resolution needs to be reduced, and the output image size needs to be cropped on the image sensor side, sacrificing a certain field of view, which is not conducive to the monitoring field of view requirements; to ensure high frame rate and high resolution, it is necessary to improve the back-end digital signal processing (Digital Signal Processing, referred to as DSP), and process large data streams in real time through powerful coding capabilities, but the cost is relatively high and the cost is high.
