SWING DISPLAY DEVICE AND METHOD
First Claim
Patent Images
1. A swing display device for displaying a message image while swinging the swing display device back-and-forth in the air, the device comprising:
- a display image input operable to generate an image data representing the message image for display;
a CPU operable to calculate a message image producing time for producing the message image during one swing of the swing display device, operable to divide the message image into a plurality of line segments which are sequentially produced with a calculated time interval, and operable to generate a first marginal time before the occurrence of the message image and a second marginal time after the occurrence of the message image;
a timer operable to count a single swing time including the first marginal time, the message image producing time, and the second marginal time, and to produce a synchronizing signal after every single swing time;
a timing indicator operable to produce a sign in response to the synchronizing signal;
an array of light sources aligned vertically; and
a controller operable to control the array of light sources to turn on and off the light sources in response to the information of said message image contained in one line segment.

Abstract
A swing display device includes a CPU which calculates and produces synchronizing signal relative to the length of the message to be displayed. Learning the speed of the synchronizing signal, the user swings the swing display device back-and-forth according to the synchronizing signal to produce the image in the air.

18. A swing display method for displaying a message image while swinging a swing display device back-and-forth in the air, the method comprising:
-
generating by a display image input an image data representing the message image for display; calculating by a CPU a message image producing time for producing the message image during one swing of the swing display device; dividing by the CPU the message image into a plurality of line segments which are sequentially produced with a calculated time interval; generating by the CPU a first marginal time before the occurrence of the message image and a second marginal time after the occurrence of the message image; counting by a timer a single swing time including the first marginal time, the message image producing time, and the second marginal time, and producing a synchronizing signal after every single swing time; producing by a timing indicator a sign in response to the synchronizing signal; controlling by a controller an array of light sources aligned vertically so as to turn on and off the light sources in response to the information of said message image contained in one line segment. - View Dependent Claims (19, 20, 21, 22, 23)
