Electronic appliance
View Patent ↗A video camera picks up an image of an operator. The picked-up image is subjected to a mirror image conversion. An image for operation, including operation buttons and the operator's image that is subjected to the mirror image conversion are mixed and displayed on a screen of a television receiver. The operator selects a desired operation button by using a universal remote controller with light emitting portions, and executes the operation on the screen. A detecting portion in the television receiver detects which operation button is operated, and executes a control operation corresponding to the operated operation button.
1. An electronic appliance comprising:
a display device;
a video camera that picks up an image of an operator positioned in front of the display device;
a mirror image converter configured to execute a mirror image conversion of the image picked up by the video camera;
an operation image generator configured to generate an image for operation, including an image of at least one operation button;
a mixer configured to mix an image signal of the image that underwent the mirror image conversion with an image signal of the image for operation;
a detector configured to detect a predetermined selecting operation for selecting one of the at least one operation button made by an operator displayed on a screen of the display device using an on-hand control unit having light emitting portion, with a mixed image obtained by the mixer displayed on the screen of the display device; and
a controller configured to execute a control operation corresponding to the selected operation button for which the predetermined selecting operation is detected by the detector.
2. An electronic appliance according to claim 1 , wherein the light emitting portion of the on-hand control unit has a light emitting means for emitting a light in N colors (N is an integer of 2 or more), and the on-hand control unit has N color selecting buttons corresponding to the N colors,
the detector has a discriminating means for discriminating the N colors, and
the controller executes a control operation corresponding to a color discriminated by the discriminating means of the detector.
3. An electronic appliance according to claim 1 , wherein the on-hand control unit has operation buttons used to cause the light emitting portion to emit the light corresponding to the predetermined selecting operation, and an infrared light emitting means for emitting infrared information that indicates a determination of the predetermined selecting operation, whereby the light emitting portion and the infrared light emitting means are configured to operate according to an operation state of the operation buttons,
the electronic appliance further comprising an infrared sensor that senses the infrared information, and
wherein the controller determines the predetermined selecting operation detected by the detector based on the infrared information indicating the determination of the predetermined selecting operation, sensed by the infrared sensor, and executes the control operation.
4. An electronic appliance according to claim 1 , wherein the on-hand control unit has a selfluminous means for emitting lights in light emission patterns corresponding to M (M is an integer of 1 or more) spatial frequency regions, and M frequency region selection buttons that correspond to the light emission patterns corresponding to M spatial frequency regions,
the detector has a discriminating means for discriminating the light emission patterns corresponding to M spatial frequency regions, and
the controller executes the control operation corresponding to a spatial frequency region discriminated by the discriminating means of the detector.
5. An electronic appliance according to claim 1 , wherein the on-hand control unit has a selfluminous means for emitting lights in N colors (N is an integer of 1 or more) in each of light emission patterns corresponding to M (M is an integer of 1 or more) spatial frequency regions, and M×N frequency/color region selection buttons that correspond to N colors in each of the light emission patterns corresponding to M spatial frequency regions,
the detector has a discriminating means for discriminating M×N types of light emission states, and
the controller executes the control operation corresponding to a light emission state discriminated by the discriminating means of the detector.
