Background technique

For those who are familiar with the prior art, the traditional image retrieval device with LED (Light Emitting Diode; Light Emitting Diode) indicator light provides a time indication function. ) flashing frequency to inform the countdown time. Usually the closer to the time to take pictures, the faster the flashing frequency. There are also digital cameras that use light-emitting diodes (LEDs) as focus assist lights. When taking pictures at close distances and when the ambient light is insufficient, the focus assist lights emit a line of light on the scene to help the camera lens obtain more light to focus. achieve the purpose of focusing.

Generally speaking, the flash (Flash) is the most common artificial light source used in photography. At present, the flash that is generally configured in the image retrieval device cannot shoot continuously due to the charging time of the flash when it is used in a low-light environment.
