IMAGE QUALITY ADJUSTMENT METHOD AND SYSTEM

摘要

Provided are an image quality adjustment method and system, which are suitable for a video device. The image quality adjustment method comprises: when a video device is started, according to whether the current time falls into a pre-determined time period, executing a corresponding image quality adjustment program; invoking a set value of a corresponding image quality parameter by detecting ambient light; and acquiring a reference value of the corresponding image quality parameter by judging the type of the current video content, and then deciding whether to adjust the image quality parameter by comparing the set value with the reference value, thereby realizing the effect of adaptively adjusting the image quality parameter, thus improving the use convenience of the video device.

1. A method for adjusting image quality, applicable to a video device, comprising:
acquiring a current time of a displaying video of the video device, determining whether the current time falls within a pre-determined time period, calling a default value of an image quality parameter if the current time does not fall within the pre-determined time period, and performing an image quality adjustment procedure if the current time falls within the pre-determined time period; wherein the image quality adjustment procedure comprises: detecting a brightness value of ambient light; calling a setting value of a corresponding image quality parameter according to the brightness value; determining the type of the current video content, and acquiring a reference value of the corresponding image quality parameter according to the type of the video content; and comparing the setting value of the image quality parameter with the reference value of the image quality parameter, adjusting and reducing the setting value of the image quality parameter to the reference value of the image quality parameter if the setting value of the image quality parameter is greater than the reference value of the image quality parameter, and continuously calling the setting value of the image quality parameter if the setting value of the image quality parameter is equal to or less than the reference value of the image quality parameter.
