Fig. 1 shows the realization flow of the video camera diurnal pattern changing method that the embodiment of the present invention provides, and details are as follows:
In step S101, obtain the current regulating parameter of described video camera and/or camera review content information.
Concrete, the regulating parameter that described video camera is current, can comprise as parameters such as photosensitivity, BLC values.
Wherein, described photosensitivity is that film or sensitive chip are to the chemical reaction velocity of light.Low speed refers to film or the film of ISO less than 100, and middle photosensitivity refers to ISO 200 ~ 800, and ISO is ISO more than 800.When using camera, video camera can choose the egative film of different photosensitivity (speed) in response to the brightness of shooting environmental, and such as the environment at general cloudy day can use iso200, and dark is as stage, and the environment of concert can with iso400 or higher.
In the present invention, video camera changes iso value by the multiplication factor changing signal amplifier in sensitive chip, but when promoting iso value, is also that the illuminance in camera coverage reduces.
Described BLC, also referred to as BLC, be that picture is divided into several different region, each region exposes respectively.In some application scenario, may comprise a very bright region in visual field, involved main body is then among the encirclement in very bright region, and picture a slice is dim, without level.The signal level now detected due to AGC is not low, therefore the gain of amplifier is very low, the shading value of picture main body can not be improved, when introducing BLC, video camera only detects a sub regions of whole visual field, by the working point asking the average signal level in this region to determine agc circuit.
Described camera review content information, can comprise the brightness value, RGB component value etc. as image.
Wherein, the brightness value of described image, refers to the light levels of picture, and unit moral may draw every square meter (cd/m2) or claim nits, the namely candle light of every square centimeter point.
