Problems solved by technology

[0003] However, after long-term use of the LED lamp beads in the external flash, there is a deviation between chromaticity and luminous intensity, which leads to the fact that the actual luminous brightness, chromaticity and other luminous parameters cannot reach the preset luminous parameters, so that the expected fill light cannot be achieved.

Abstract

The invention provides an external flash lamp and a color correction system of the external flash lamp. The external flash lamp comprises a light source unit, a driving unit and a control unit. The driving unit drives the light source unit to emit light; the control unit is electrically connected with the driving unit, and the control unit is electrically connected with the color correction detection equipment; the control unit is used for receiving light emitting information, detected by the color correction detection equipment, of the light source unit and generating color correction result information after performing color correction processing according to the light emitting information; and the driving unit drives the light source unit to emit light according to the color correction result information. According to the scheme, the light-emitting color correction of the light source unit of the external flash lamp is realized.

Description

technical field [0001] The present application relates to the technical field of flashlights for photographing, and in particular to an external flashlight and a color correction system for the external flashlight. Background technique [0002] With the development of mobile communication technology, mobile terminals play an increasingly important role in people's life and work. Especially some mobile terminal devices with a camera function, such as mobile phones, MP4, PDA, notebook computers, etc. The camera functions of these mobile terminals have brought great pleasure to people's lives. Taking pictures requires a light source. In addition to natural light, artificial light is often needed to assist in taking pictures. The artificial light source that comes with a mobile terminal with a camera function often cannot meet the actual needs of use. For this reason, people often use an external flash to assist in shooting. [0003] However, after long-term use of the LED lamp...
