Abstract
Abstract A stereoscopic image displaying apparatus includes: field switching signal generating unit for generating a field switching signal alternately indicating odd field periods and even field periods from an original picture signal; delaying unit for delaying the original picture signal and producing a delayed picture signal; stereoscopic image signal generating unit for alternately selecting one of the original picture signal and the delayed picture signal in accordance with the field switching signal to generate a stereoscopic image signal; and display unit for displaying the stereoscopic image signal by alternately supplying pictures of the original picture signal to one eye of a user and pictures of the delayed picture signal to the other eye of the user on the basis of the field switching signal.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
180 words
A stereoscopic image displaying apparatus comprising: field switching signal generating means for generating a field switching signal alternately indicating odd field periods and even field periods from an original picture signal; delaying means for delaying the original picture signal and producing a delayed picture signal; stereoscopic image signal generating means for alternately selecting one of the original picture signal and the delayed picture signal in accordance with the field switching signal to generate a stereoscopic image signal; and display means for displaying the stereoscopic image signal by alternately supplying pictures of the original picture signal to one eye of a user and pictures of the delayed picture signal to the other eye of the user on the basis of the field switching signal; a moving direction detecting means for detecting a direction of a moving picture component in the original picture signal based on the original picture signal and the delayed picture signal; and an inverting means for inverting a logical level of the field switching signal to be supplied to the display means in accordance with the detected direction.
Claim 2
Dependent Claim
180 words
A stereoscopic image displaying apparatus comprising: field switching signal generating means for generating a field switching signal alternately indicating odd field periods and even field periods from an original picture signal; delaying means for delaying the original picture signal and producing a delayed picture signal; stereoscopic image signal generating means for alternately selecting one of the original picture signal and the delayed picture signal in accordance with the field switching signal to generate a stereoscopic image signal; and display means for displaying the stereoscopic image signal by alternately supplying pictures of the original picture signal to one eye of a user and pictures of the delayed picture signal to the other eye of the user on the basis of the field switching signal; a moving direction detecting means for detecting a direction of a moving picture component in the original picture signal based on the original picture signal and the delayed picture signal; and an inverting means for inverting a logical level of the field switching signal to be supplied to the display means in accordance with the detected direction.
Claim 3
Dependent Claim
26 words
An apparatus according to claim 1, wherein said delaying means comprises a video memory for delaying the original picture signal by one or more frame periods.
Claim 4
Dependent Claim
43 words
An apparatus according to claim 1, wherein said display means comprises a monitor for displaying the stereoscopic image signal; and a shutter means arranged between the monitor and the eyes of the user for alternately shielding one of the eyes of the user.
Claim 5
Dependent Claim
67 words
An apparatus according to claim 1, further comprising a picture movement detecting means for detecting a moving picture component in the original picture signal based on the original picture signal and the delayed picture signal; and a display control means for permitting said displaying means to alternately supply one of the original picture signal and the delayed picture signal only when the moving picture component is detected.
Claim 6
Dependent Claim
43 words
An apparatus according to claim 4, wherein said display control means permits said display means to simultaneously supply both of the original picture signal and the delayed picture signal to the eyes of the user when the moving picture component is not detected.
Claim 7
Dependent Claim
88 words
An apparatus according to claim 1, further comprising at least one additional delaying means for producing the delayed picture signal of different delay time; a moving quantity detecting means for detecting quantity of a moving picture component in the original picture signal based on the original picture signal and one of the delayed picture signals; and a selecting means for selecting one of the delayed picture signal to be supplied to the stereoscopic image signal generating means on the basis of the quantity of the moving picture component.
Claim 8
Dependent Claim
28 words
An apparatus according to claim 6, wherein each of said delaying means comprises a video memory for delaying the original picture signal by one or more field periods.
Claim 9
Dependent Claim
36 words
An apparatus according to claim 1, further comprising a display position control means for shifting a display position of one of the original picture signal and the delayed picture signal in horizontal direction on the monitor.
Claim 10
Dependent Claim
30 words
An apparatus according to claim 8, wherein said display position control means shifts positions of horizontal synchronizing signals in one of the original picture signal and the delayed picture signal.
Claim 11
Dependent Claim
54 words
An apparatus according to claim 8, wherein said delaying means comprises a video memory, and said display position control means shifts a read-out position of the video memory from which the original picture signal stored therein is read out, with respect to a writing position from which the original picture signal has been written.
Claim 12
Dependent Claim
70 words
An apparatus according to claim 8, further comprising a moving direction detecting means for detecting a direction of a moving picture component in the original picture signal based on the original picture signal and the delayed picture signal, and said display position control means selecting one of the original picture signal and the delayed picture signal whose display position is to be shifted, in accordance with the detected moving direction.
Claim 13
Dependent Claim
50 words
An apparatus according to claim 1, further comprising vertical shifting means for delaying one of the original picture signal and the delayed picture signal by one or more horizontal line periods so as to shift a display position of the picture signal in vertical direction of the original picture signal.
