Abstract

A focus determining system, a focus determining method and a remote controller pairing method of a projection device are provided. The focus determining system comprises an electrical focusing unit for adjusting the focal length of a projection lens, and a focus determining control unit. The focus determining system is characterized in that the electrical focusing unit comprises a focusing assembly for moving the lens and a focusing driving motor for driving the focusing assembly; the focus determining control unit comprises a focus determining control processor and a focus determining touch control panel; the focus determining touch control panel is electrically connected with the focus determining control unit; and the focus determining control unit is electrically connected with the focusing driving motor. The focus determining system is convenient and quick in focusing determination. The focus determining method gradually reduces the lens focusing stroke range and the zooming speed to achieve more precise focus determination, so that projection images are clearer, and the usage experience of the projection device to the user is improved.

Description

technical field [0001] The present invention relates to the technical field of projection equipment, and in particular to a focusing system of projection equipment, a fast focusing method based on the focusing system, and a remote controller pairing method. Background technique [0002] Since the usage scenarios of the projection device are uncertain, the projection distances between the lens and the projection surface are also different, so that the projection device needs to be refocused every time it is turned on. The convenience of the fixed focus of the projection device has a greater impact on the user experience. In addition, the inaccurate fixed focus will have a direct impact on the definition of the projection image quality, thereby affecting the performance of the projection device. At present, most of the traditional projection equipment manually adjust the focus through the set focus knob, the focus speed is slow, and the focus accuracy needs to be further impro...
