Problems solved by technology

[0003] However, due to the limitations of the shutter and aperture, digital cameras and traditional cameras both face brightness problems in image capture (Brightness)
When the weather is clear and sunny, the light source will naturally not be a problem in image capture; if the weather is dark, or the shooting location is indoors, the camera does not capture enough light at the moment of capturing the image, and the photo or The image is easily blurred due to the poor response of the photosensitive element and the effect is poor. The purpose of capturing the image is bound to be greatly reduced.
[0004] In the past, in traditional cameras and digital camera devices, it is necessary to add photometric sensors to prompt and activate the flash mechanism of the camera, so as to obtain sufficient light through the intervention of unnatural factors to obtain good image quality. This measure is bound to increase the manufacturing cost relatively. On the other hand, under the premise of the minimization of commodity devices, installing photometric sensing components in the camera will inevitably increase the volume capacity of the camera indirectly, resulting in the miniaturization design of the finished product itself. prone to bottlenecks

Embodiment Construction

[0011] The main key components of digital cameras include lenses, photosensitive components, chipsets, storage media and LCD panels. The photosensitive components include CCD (Charge-Coupled Device, photosensitive coupling device) and CMOS (Complementary Metal-Oxide Semiconductor, complementary metal oxide Semiconductor) Two types; CCD is a semiconductor that can record light changes in a digital camera. The surface of the photosensitive component contained in it has the ability to store charges and is arranged in a matrix. When the surface receives light, it will react the charge in On the components, the signals generated by all photosensitive elements on the entire CCD constitute a complete picture. Therefore, CCDs are usually used in digital cameras and scanners as photosensitive components.

[0012] CMOS and CCD are also semiconductors that can record light changes in digital cameras. They are mainly semiconductors made of two elements, silicon and germanium, so that N (ne...

Abstract

The invention relates to a software photometric system and its method, which uses the gathered video pixel and assigns many differ pixels which are posted on special location of picture and analyzes them into red coloring matter, green coloring matter and blue coloring matter and uses the average brightness value as the code of system device executing supplementary light source.

Description

technical field [0001] The present invention relates to a photometric system and its method, in particular to a photometric system and its method using a software program. Background technique [0002] When taking pictures with a traditional camera, the results of the pictures cannot be known immediately. Generally, digital cameras are equipped with LCD screens, and the results can be seen immediately. If you are not satisfied, you can wash it out and retake. No matter how long it takes, it will not turn yellow easily like film, and it even has a camera function. Because digital cameras have many powerful functions, they gradually replace the traditional camera market. [0003] However, due to the limitations of the shutter and aperture, digital cameras and traditional cameras both face the problem of brightness in image capture. When the weather is clear and sunny, the light source will naturally not be a problem in image capture; if the weather is dark, or the shooting lo...
