Abstract

The invention discloses a camera with multi-channel flash synchronization signals, which includes a connected camera body and a camera interface, wherein the camera interface includes a synchronization signal generation module, an input module and a power supply module, and the power supply module is a synchronization signal generation module, The input module provides power, and the synchronous signal generation module receives the pulsed flash synchronous signal of the image sensor chip, generates multiple synchronous signals with different effective sequences according to the input information received by the input module, and controls the opening and closing of multiple external flashes; the user The execution sequence of multiple flashes can be customized according to the actual situation. The functions are integrated inside the camera and do not take up extra space when applied.

Description

technical field [0001] The invention relates to a camera with multiple flash synchronization signals. Background technique [0002] For the existing cameras on the market for industrial, transportation, medical, scientific research, commercial, household and other industries, including smart cameras, there are usually flash synchronization output signals, which are used to control the external flash, so that the flash and the camera Synchronization, that is, the flash is turned on only when the camera image sensor chip is required for integration or when the camera takes a picture. With this signal, the flash light does not need to be always on, which not only reduces power consumption, but also reduces the interference of the strong light of the flash light on the human eye. [0003] However, the existing industrial cameras only have one flash synchronization signal, and the disadvantage is that they can only control one or a group of flashes or light sources. However, in...
