An information processing apparatus includes a first information processor, a plurality of second information processor, and a plurality of temperature detecting units detecting temperature in the vicinity of each of the plurality of second information processors. The first information processor includes an application program execution control unit controlling execution of an application program, a distributed processing control unit controlling distributed processing, a recording unit recording first information relating to temperature detected by the temperature detecting unit, and second information relating to the execution of the process of the second information processor, an anomaly detecting unit detecting an anomaly in the temperature detected by the temperature detecting unit, and an anomaly-time control unit controlling the distributed processing of the distributed processing control unit in response to the temperature anomaly detected by the anomaly detecting unit.

An image display controller includes a first memory for storing data of an image to be displayed in a first window; a second memory for storing data of an image to be displayed in a second window, where no data is read from the second memory for image display during the data reading operation in the first memory; and a third memory for storing data of an overlay image on which the image of the first or second memory is superimposed, and also storing window data to set the range of the windows. The controller is arranged to prevent any disordered display of images and is capable of displaying an increased number of windows.

A method and apparatus for shading images by approximating a three-dimensional curved surface for computer graphics. Shading of a two-dimensional surface is provided by varying pixel brightness values to indicate a depth dimension of the two-dimensional surface. A plurality of polygons are employed, with each polygon being used to approximate a portion of the curved surface. A coordinate grid is provided extending in horizontal and vertical directions. The polygons are plotted on this coordinate grid. Coordinate grid points of the coordinate grid each represent respective pixels whose brightness is to be varied for the graphics. Scanning occurs across scan lines in a horizontal direction across the grid from grid point to grid point. Vertices of the polygons are provided on the coordinate grid, which vertices may not necessarily lie directly on a grid point. Brightness values at each vertex of the polygon are provided. Using these brightness values, by a process known as sub-pixel addressing, brightness values at the pixels at the grid points of the coordinate grid lying inside of the polygons are determined by linear interpolation based on brightness values at locations where pixels are not provided on sides of the polygon.

Shading method and shading apparatus for computer graphics

A video source selecting system for a television receiver has a built-in video tape recorder (video deck) for sequentially selecting for display, a plurality of video signals on various channels, such video signals including at least a video signal from the built-in video deck, and a video signal from at least one external video input terminal. A selected video signal is supplied to a monitor television receiver. When the built-in video tape recorder is placed in its playback mode, the plurality of video signals are switched selected sequentially, while when the built-in video tape recorder is not placed in its playback mode, it is skipped by the switch, whereby the order in which the video signals are switched is in response to the operational state of the built-in video tape recorder.

Video source selecting system

A video display system has a circuit for sequentially superimposing N (N.gtoreq.2) information signals upon a video signal for display on the picture screen of a television receiver, at predetermined positions in parallel relation, and a circuit for changing the display positions so as to display information signals sequentially from a corner of the picture screen.

Video display system with selective display of operating conditions

A method and apparatus for use with a television receiver that processes a television signal in digital form and that has the functional units of the receiver controlled by digital data stored in internal registers, in which a dedicated non-volatile memory is provided for storing initial data along with a control circuit for setting such initial data into the appropriate register so that when the receiver is adjusted for the first time following manufacture spurious data will not cause circuit elements of the receiver to be damaged.

Nonvolatile memory system for digital television tuner

Method and apparatus for use with a television receiver wherein a television signal is processed in a digital form and which includes a memory for storing data to control such processing, in which a circuit is provided for refreshing the data in the memory at successive vertical blanking periods and a circuit is also provided for writing input data into the memory at the appropriate location at any time new data is desired to be input by the user. An operating method is also provided to accomplish the functional tasks of the refreshing circuit and interrupt circuit.
