A television operation method whereby a desired content screen can be easily shown on a TV receiver by control operation on the display of a remote terminal. When the TV display of the TV receiver shows a received program screen and the remote display of the remote terminal shows another received program screen, if the screen shown on the remote display is transferred to the TV display, a reception remote control screen to enable channel selection appears on the remote display. If buttons are operated so as to show a related web screen on the remote display and transfer the related web screen to the TV display, a web remote control screen for control of a cursor on the related web screen appears on the remote display.

There is provided an input unit adapted for non-contact input manipulation, which permits a user to smoothly accomplish an intended input manipulation. The input unit includes: a position detecting portion for detecting a position of a manipulating object such as a user's hand manipulating the input unit; a position change detecting portion for detecting a change in the position of a point on the manipulating object based on a detection output from the position detecting portion, the point being the closest to the position detecting portion; and an image display section. The position change detecting portion detects the change in the position of the point closest to the position detecting portion in a predetermined area. The image display section changes the display image according to a detection output from the position change detecting portion.

A method of displaying a document with an image. Tabs 351 to 354 associated with the same document are set on a document screen 33 of a document display screen 32, with one of the tabs (351) open. A base image 36 attached to the document is displayed on the tab 351. At the position for a comment, etc. of this base image, objects (added information) such as a comment 37, a pattern 38 related to the comment, a symbol 39 and an arrow 41 are added. These objects can be added by operating an “add” button 16a or an object select section 42. Also, an added object list screen 34 indicating a list of the objects added is displayed. The added information such as a comment added to the base image can be immediately viewed in the state related to the base image.

A noise cancellation method includes: inputting an interference wave signal detected near a receiver section, and changing the phase and the amplitude of the input signal to generate a cancellation signal that cancels the input signal; performing correlation calculations on a signal obtained by adding the cancellation signal to a communication signal received by the receiver section and a code replica of a PRN code used for the communication signal, within a given correlation calculation target range that is included within a code phase range and a frequency range; and performing the correlation calculations within a non-signal range outside the correlation calculation target range, and controlling a phase shift amount and an amplitude change rate of the input signal based on the correlation calculation result.
摘要:
A signal received by an antenna or the like is input from an input terminal, and is amplified by an amplifier section together with thermal noise superimposed on the received signal. An addition section adds the signal amplified by the amplifier section to a cancellation signal generated by a cancellation signal generation section, whereby the noise superimposed on the received signal is canceled.

A noise cancellation method includes: inputting an interference wave signal detected near a receiver, and changing the phase and the amplitude of the input signal to generate a cancellation signal that cancels the input signal; adding the cancellation signal to a received signal received by the receiver, amplifying the resulting signal by a given amplification factor, and converting the amplified signal into a digital signal; controlling the amplification factor based on a frequency ratio of each signal value of the digital signal; and controlling amounts by which the phase and the amplitude of the input signal are changed, based on the amplification factor.
摘要:
A cancellation signal generation section generates a cancellation signal which cancels an alternating-current component of a power supply terminal voltage of a digital signal processing circuit section, and a synthesis section synthesizes the generated cancellation signal and a power supply voltage of an analog signal processing circuit section to cancel noise superimposed on the power supply voltage.
摘要:
A coil section detects undesirable radiation generated from a baseband process circuit section mounted at a specific position on a substrate, the coil section including a wire with a specific shape that is disposed at a position close to the baseband process circuit section, and a cancellation signal generation section generates a signal that cancels the undesirable radiation detected by the coil section.
