IMAGE SIGNAL PROCESSING DEVICE AND ACTIVE SHUTTER GLASSES
First Claim
1. An image signal processing device comprising:
- an image signal obtainment unit configured to obtain a three-dimensional image signal for allowing three-dimensional viewing of images using a pair of active shutter glasses;
an output unit configured to output the three-dimensional image signal;
a judgment unit configured to judge whether or not the pair of active shutter glasses is in a valid state which allows three-dimensional viewing using the pair of active shutter glasses, based on a result of obtaining information from outside said image signal processing device; and
a control unit configured to switch, by controlling said output unit, an output signal from said output unit, from the three-dimensional image signal to a two-dimensional image signal associated with the three-dimensional image signal, when a result of the judgment by said judgment unit indicates that the pair of active shutter glasses is not in the valid state.

Abstract
The image signal processing device includes: an image signal obtainment unit which obtains a three-dimensional image signal for allowing three-dimensional viewing of images using a pair of active shutter glasses; an output unit which outputs the three-dimensional image signal; a judgment unit which judges whether or not the pair of active shutter glasses is in a valid state which allows three-dimensional viewing using the pair of active shutter glasses, based on a result of obtaining information from outside the image signal processing device; and a control unit which switches, by controlling the output unit, an output signal from the output unit, from the three-dimensional image signal to a two-dimensional image signal associated with the three-dimensional image signal, when a result of the judgment by the judgment unit indicates that the pair of active shutter glasses is not in the valid state.

7. A pair of active shutter glasses which performs an operation of alternately blocking a field of vision of a left eye and a field of vision of a right eye of a user in synchronization with switching between each of left-eye images and right-eye images which are displayed alternately, said pair of active shutter glasses comprising
a communication unit configured to transmit, during an operational period, a predetermined signal which can be received by a device on a displaying-side of the left-eye images and the right-eye images, the operational period being a period of time during which said pair of active shutter glasses performs the operation.

11. An image signal processing method executed by an image signal processing device, said method comprising:
-
obtaining a three-dimensional image signal for allowing three-dimensional viewing of images using a pair of active shutter glasses; outputting the three-dimensional image signal; judging whether or not the pair of active shutter glasses is in a valid state which allows three-dimensional viewing using the pair of active shutter glasses, based on a result of obtaining information from outside the image signal processing device; and switching an output signal outputted in said outputting, from the three-dimensional image signal to a two-dimensional image signal associated with the three-dimensional image signal, when a result of the judgment in said judging indicates that the pair of active shutter glasses is not in the valid state.

12. A program recorded on a non-statutory computer-readable recording medium, for controlling operations of an image signal processing device, said program causing a computer to execute:
-
obtaining a three-dimensional image signal for allowing three-dimensional viewing of images using a pair of active shutter glasses; outputting the three-dimensional image signal; judging whether or not the pair of active shutter glasses is in a valid state which allows three-dimensional viewing using the pair of active shutter glasses, based on a result of obtaining information from outside the image signal processing device; and switching an output signal outputted in said outputting, from the three-dimensional image signal to a two-dimensional image signal associated with the three-dimensional image signal, when a result of the judgment in said judging indicates that the pair of active shutter glasses is not in the valid state.
