Abstract: A display system includes a first display device and a second display device. The first display device includes a first display and a first operator. The second display device includes a second display. When one part of the display image displayed on the first display is designated by a touch operation, the second display displays an extracted image. The extracted image is an image obtained by extracting, from the display image, a partial image including a portion designated by the touch operation in the display image.

Abstract: A touch panel display device includes a display unit, a touch panel, a display processing unit, a setting processing unit, and a restriction processing unit. The touch panel detects a touch operation on the display unit, the display processing unit displays a specific image on a part or all of a display screen of the display unit in a state where an input image is being displayed on the display unit, the setting processing unit sets an operation restriction range according to a touch operation on the specific image, and the restriction processing unit switches whether to perform output of operation information corresponding to the position of the touch operation to an external device according to whether the position of the touch operation detected by the touch panel is within the operation restriction range.

Abstract: A television receiver for content with which genre information is associated includes: a basic picture quality information receiving section which associates, with a single piece of genre information, a plurality of candidates for picture quality information regarding the content with which the genre information is associated, and which receives basic picture quality information indicating which one of the plurality of candidates is based on; a picture quality correction information creating section which receives picture quality correction information for further correcting the picture quality, and which creates, in accordance with the basic picture quality information and the picture quality correction information, information for correcting the picture quality; and a picture processing section which corrects the picture quality and which creates a picture to be displayed by a liquid crystal display device.

Abstract: A television receiver includes a genre identification section that identifies a genre of contents, a video processing section that displays the contents upon correcting the contents with an image quality parameter set in accordance with the identified genre in advance, a display control section that displays, while the contents is displayed, an adjustment item for adjusting a value of the image quality parameter, a parameter value adjustment section that adjusts the value of the image quality parameter based on entry by a user, and a parameter value changing section that changes the value of the image quality parameter, when the identified genre changes to another genre, to a value set in advance corresponding to a genre after the genre changes, and the parameter value changing section changes the value of the image quality parameter in a different period of time depending on whether or not the adjustment item is displayed.

Abstract: The system comprises a frequency number memory device for storing information regarding the frequencies of respective tones, a keyboard switch for reading out frequency number information corresponding thereto from the memory device, an address generator including an adder for adding a predetermined number of the frequency number information thereby producing an address signal consisting of plural bits, address composers for processing the bits of the address signal and thereby composing digital tone signals constituting a saw-tooth, square and triangular waveshape, and digital-analog converters for converting the digital tone signals into analog tone signals, which are thereafter used to synthesize waveshapes of any tone.
