Method for automatically switching image display modes

Abstract

The invention relates to a method for automatically switching image display modes. The method includes the steps of providing an automatic display mode switching system; on the basis of fine image processing and two-stage filtering mode, accurately judging the brightness of an image currently displayed on a screen; and automatically switching the display screen to a scene projected by a liquid crystal projector when the overall brightness of the currently displayed image is too high.

Description

technical field

[0001] The invention relates to the image field, in particular to an image display mode automatic switching method. Background technique

[0002] Liquid crystal projectors can be divided into liquid crystal panel projectors and liquid crystal light valve projectors. The former is the main product in the projector market. Liquid crystal is a substance between liquid and solid. It does not emit light itself, and its working properties are greatly affected by temperature. Its working temperature is -55°C to +77°C. Projectors use the photoelectric effect of liquid crystals, that is, the arrangement of liquid crystal molecules changes under the action of an electric field, which affects the light transmittance or reflectivity of the liquid crystal unit projector, thereby affecting its optical properties, and producing images with different gray levels and colors. image. Because LCD projectors have good color reproduction, resolution up to SXGA standard, small si...

Embodiment Construction

[0014] Embodiments of the present invention will be described in detail below.

[0015] In order to overcome the above-mentioned shortcomings, the present invention builds a method for automatically switching image display modes, which includes providing an automatic display mode switching system, based on refined image processing and two-stage filtering mode, the brightness currently displayed on the screen is accurately It is judged that when the overall brightness of the current displayed image is too high, the display screen is automatically switched to a scene projected and displayed by a liquid crystal projector. The automatic display mode switching system effectively solves the problem of switching from a display mode to a projection mode.

[0016] The display mode automatic switching system shown according to the embodiment of the present invention includes:

[0017] The display driving device is set in the mobile terminal, and is used for acquiring current display dat...
