Example Embodiment

[0028] Certain words are used in the specification and the following claims to refer to specific elements. Those skilled in the art should understand that the same element may be called by different terms. This specification and the subsequent claims do not use differences in names as a way of distinguishing elements, but use differences in functions of elements as a basis for distinction. The "including" mentioned in the entire manual and the subsequent rights is an open term, so it should be interpreted as "including but not limited to...". In addition, the term "coupling" includes any direct and indirect connection means in the manual and the subsequent rights. Therefore, if it is described that a first device is coupled to a second device, it means that the first device can be directly connected to the second device (including signal connection methods such as electrical connection, wireless transmission, optical transmission, etc.), or through Other devices or connecting...

Abstract

The invention discloses a digital imaging device, which comprises a light source module, an image synchronizing signal generation circuit and a light source controller, wherein the image synchronizing signal generation circuit is used for generating an image synchronizing signal; and the light source controller is coupled to the light source module and the image synchronizing signal generation circuit, and is used for generating a light source control signal which is synchronous with the image synchronizing signal and has frequency corresponding to that of the image synchronizing signal to control the light output of the light source module. The light source controller controls the light output time and intensity of the light source module according to the image synchronizing signal, so the amount of light in the image acquisition of the digital imaging device can be increased to further reduce or solve the problem that an image formed by the digital imaging device is extremely dark or has extremely low contrast.

Description

technical field [0001] The present invention relates to digital imaging technology, in particular to a digital imaging device with a built-in light source module whose light emitting mode corresponds to an image acquisition frequency (image acquisition frequency) and a related object detection system. Background technique [0002] The application fields of digital imaging technology are quite extensive. Many applications, such as digital camera, digital video camera, digital microscopic measurement, and automatic recognition of image objects, rely on digital imaging technology to be realized. [0003] The performance of digital imaging technology has a great influence on the image quality, especially on the image quality of the image details. If the ambient light is insufficient during imaging, the image will be too dark and the contrast will be too low. If there is relative movement between the digital imaging device and the target object, it is also easy to cause the prob...
