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.

The invention provides an external flash lamp. The external flash lamp comprises a light source unit, a driving unit, a first communication unit and a color correction processing unit. The light source unit comprises one or more LED light sources. The driving unit drives the light source unit to emit light; the first communication unit is used for communicating with terminal device so as to receive a color correction control instruction sent by the terminal device; the color correction processing unit is connected with the driving unit and is electrically connected with the first communication unit, and the color correction processing unit receives the color correction control instruction transmitted by the first communication unit, carries out color correction processing on the light emitting information of the light source unit and generates color correction result information; the driving unit drives the light source unit to emit light according to the color correction result information. According to the invention, color correction of the external flash lamp light source unit 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...
