Abstract

A touch screen includes a power supply unit, configured to supply power; an image capturing unit, configured to capture images; a storage unit, configured to temporarily store screen content; an image display unit, configured to display the screen content; and a processing unit, coupled to the power supply unit, the image capturing unit, the storage unit, and the image display unit, configured to execute an image display method. The image display method includes capturing an image of an area in front of the touch screen; determining a position of a speaker according to the image, and determining a blocked area and an unblocked area according to the position; and displaying screen content related to the blocked area in the unblocked area.

Claims15

Dependent claims

An image display method for a touch screen, comprising steps of:

capturing an image of an area in front of the touch screen;
determining a position of a speaker user according to the image, and determining a blocked area of the touch screen and an unblocked area of the touch screen according to the position of the speaker user;
down scaling a first screen content of the unblocked area and a second screen content of the blocked area according to the unblocked area;
and
simultaneously displaying the downscaled first screen content and the downscaled second screen content in the unblocked area;
wherein when the blocked area is determined to be a middle area of the touch screen, the step of down scaling the first screen content of the unblocked area and the second screen content of the blocked area according to the unblocked area comprises:
dividing the second screen content of the blocked area into a left half blocked screen content and a right half blocked screen content;
performing non-proportional down scaling to the first screen content of the unblocked area, wherein the unblocked area comprises a left area and a right area of the touch screen;
obtaining a left sub-area in the left area and a right sub-area in the right area;
and
performing non-proportional down scaling to the left half blocked screen content to fit the left sub-area and the right half blocked screen content to fit the right sub-area.

A display device, comprising:

an image capturing unit, configured to capture an image in front of the display device;
an image display unit;
and
a processing unit, coupled to the image capturing unit and the image display unit, configured to
determine a position of a speaker user according to the image;
determine a blocked area and an unblocked area of the image display unit according to the position of the speaker user;
down scale a first screen content of the unblocked area and a second screen content of the blocked area according to the unblocked area;
and
simultaneously display the downscaled first screen content and the downscaled second screen content in the unblocked area;
wherein when the blocked area is determined to be one of a left area or a right area of the image display unit, the down scaling the first screen content of the unblocked area and the second screen content of the blocked area according to the unblocked area comprises:
performing proportional or non-proportional down scaling to the first screen content of the unblocked area, wherein the unblocked area comprises a middle area of the image display unit and the other one of the left area or the right area;
obtaining a sub-area in the unblocked area;
and
performing proportional or non-proportional down scaling to the second screen content of the blocked area to fit the sub-area.

11 more elements

A display device, comprising:

an image capturing unit, configured to capture an image in front of the display device;
an image display unit;
and
a processing unit, coupled to the image capturing unit and the image display unit, configured to:
determine a position of a speaker user according to the image;
divide a screen of the image display unit into a left area, a middle area, and a right area;
determine that one of the left area, the middle area, or the right area is a blocked area according to the position of the speaker user, and determine that the others of the left area, the middle area, or the right area are unblocked areas;
down scale first screen contents of the unblocked areas and a second screen content of the blocked area according to the unblocked areas, and
simultaneously display the downscaled first screen contents and the downscaled second screen content in the unblocked areas.
