Abstract: A data processor capable of preventing a system from starting up improperly due to incomplete program updating. The data processor receives, by way of an external interface, a program which is sent by communicating medium such as a broadcast wave or a telephone network from an external device and stores the received program into a memory B which is different from a memory A storing a program for the system when a version of the received program is newer than that of a program currently executed by the data processor, thereby starting up an MPU at the next time with the program stored in the memory B.

Abstract: Log information disappears when a host device storing the log information, which is histories of respective devices under connection, is disconnected. Further, when USB or the like is used as an interface bus, supplied power has to be limited with consideration to the load on the power supply of the host device. Therefore, here is a proposal of a system that permits succession of the history information of each device even if any device is disconnected and that permits efficient utilization of power.

Abstract: There is provided an image processing apparatus for temporarily stopping reproduction of an accumulation image automatically when a display mode for displaying a broadcast image (image obtained from a broadcast wave) and the accumulation image (image obtained from a storage medium) is switched to a display mode for displaying only the broadcast image, and automatically resuming the reproduction of the accumulation image when the display mode for displaying only the broadcast image is switched to the display mode for displaying the broadcast image and the accumulation image.

Abstract: The invention is to provide a display control apparatus, a display control method, a display system and a memory medium enabling to automatically realize easily observable display effectively utilizing the display area of a monitor, without any cumbersome operation. The display control apparatus of the invention learns the display resolution of a television monitor based on the voltage level of a line in the image terminal of the television monitor, and causes the television monitor to display an EPG (electronic program guide) matching such resolution. In case the resolution is 480 lines in the vertical direction, “program name only” is selected as the display item and a small font is selected. In case the resolution is 720 lines in the vertical direction, “program name” and “program content explanation” are selected and a small font is selected.

Abstract: A display control apparatus is an apparatus for outputting first image data and second image data to a display device and is constructed so as to selectively output the first image data and the second image data to the display device on the basis of a switching instruction to instruct the switching of an image to be displayed by the display device and a result of a discrimination to discriminate whether the image displayed by the display device can be switched or not.

Abstract: A display control apparatus for a display device capable of performing updating of a display state for a display element subjected to a change in display includes a display data memory for storing display data, a display controller capable of sequentially reading out the display data stored in the memory and transferring the readout display data to the display device at a predetermined period and capable of performing a partial rewrite operation of the display data stored in the memory, and a rewrite detector for detecting an address for accessing the display data memory to cause the display controller to perform the partial rewrite operation. In addition, a transfer permitting unit reads the address detected by the rewrite detector and permits transfer of only the display data of the read address to the display controller.

Abstract: A disturbance of an image in the case where a display format is switched during the display operation is prevented without exerting an adverse influence on the operation of a display apparatus side.

Abstract: A display control apparatus includes a storage unit for storing display data at each position corresponding to a display screen of a display device, a setting unit for setting a read start position of the display data from the storage unit, and a data supply unit for reading out display data in a predetermined amount from the storage unit on the basis of the read start position set by the setting unit and supplying the readout display data to the display device. The read start position set by the setting unit is set on the basis of the display data stored in the storage unit. A display control method is also disclosed.

Abstract: A display control apparatus includes a memory for storing information supplied from a processing apparatus, a detector for detecting a storage portion of the information, a display controller for performing display on a display device on the basis of the information stored in the portion detected by the detector, and a limiting unit for limiting the portion detected by the detector.

Abstract: An image is displayed in an optimum state in accordance with the state of a display. For this purpose, an FLCD interface mounted in an information processing apparatus and an FLCD for actually displaying an image are connected through a data transfer bus for transferring image data to be displayed and a serial communication line for performing communications between them. When the FLCD detects a change in its own state, this information is supplied to a CPU of the FLCD interface through the serial communication line. An instruction for changing, e.g., the operating mode is also transmitted from the FLCD interface to the FLCD through the serial communication line.

Abstract: It is an object to provide color converting method and apparatus and a display control apparatus, in which frequencies of colors which are inputted into a lookup table and the contents of the lookup table are changed in accordance with the frequencies of the colors, thereby a color reproducibility is further improved. In a color converting apparatus for converting inputted color information by using a rewritable lookup table (LUT), occurrence frequencies of output color data of the LUT are counted by using a decoder and a counter, and on the basis of the occurrence frequencies of each color which were calculated, an MPU obtains table data which makes a dispersion of the occurrence frequencies of the output color data of the LUT 100 lie within a predetermined range. The resultant table data is written into an address in the LUT.

Abstract: A high quality display image is displayed on a screen by providing an; image area information generator means (203) for generating image area information for designating an area for displaying binarization image data to be obtained by image processing of image data in the multi-level frame buffer on the screen and the area for displaying binarization image data to be obtained by approximate color conversion, based on a computer software, and a processor for processing the image data based on the image area information.
