    Abstract: A time for displaying bitmap data is shortened, and the volume of a font table is reduced. A table having all records from start 0000h to end FFFFh is used as a pointer table which imparts a start address of bitmap data. A start address of bitmap data is stored in each of the records. Thereby, the character code directly accesses a corresponding record, to thus acquire a start address. Further, the volume of a font table is diminished by means of combined use, as pointer tables, of a first pointer table from which unused character code areas are removed and a second pointer table which specifies an address positional relationship between the respective character code areas achieved before removal and the respective character codes achieved after removal.

  • Patent number: 6999082
    Abstract: A character code converting system capable of lightening the burden imposed on the management of a code converting library and mapping information on the side of users and of easily and surely carrying out code conversion of character data including types of characters such as special characters and external characters between a plurality of different coding schemes. In the character code converting system, a code converting component carries out code conversion of character data, which are exchanged between processing programs operating on the respective platforms and an internal code converting module in a middleware, based on mapping information by an external code converting part, and processes the code-converted character data into a predetermined data format, which will be code-converted by the internal code converting module, by a data processing part. Thus, even if the internal code converting module in the middleware is operating, it is possible to equivalently transmit character data.

  • Patent number: 6995779
    Abstract: A driving device drives a liquid crystal display device or the like to achieve screen display. This driving device has a driver integrated circuit device for feeding a driving signal to a display, a read-only memory having characters stored therein, and a microcomputer for feeding the driver integrated circuit device with bit-mapped data used to achieve graphic display and address data used to specify characters. The driver integrated circuit device, on receiving bit-mapped data, produces a driving signal in accordance with the received bit-mapped data, and, on receiving address data, reads the characters corresponding to the received address data from the read-only memory and produces a driving signal for character-based display.

  • Patent number: 6831645
    Abstract: One embodiment of a method of performing a font operation involves receiving a set of font data identifying a font operation to be performed. If a first font data unit in the set indicates that a first coordinate should be a background color and transparent background is enabled, the method involves outputting an enable for a second font data unit in the set. The second font data unit indicates that a second coordinate should be a foreground color. The enable for the second coordinate is output instead of a disable for the first coordinate. If instead the first font data unit in the set indicates that the first coordinate should be a background color and transparent background is disabled, the method may involve outputting a disable for the first coordinate.

  • Patent number: 6630966
    Abstract: In a device for controlling the displaying of characters for a video system, the memory for storing information relating to the displaying of the characters is partitioned into two areas. The first area (Z1, Z1′) is for storing, at fixed addresses, data and parameters for general control of the display. The second area (Z2) which is divisible into spaces (B1, B2, B3) of variable sizes stores, in each of the spaces, control parameters and data relating to the displaying of a row of characters, wherein the spaces are chained together by virtue of a parameter, the address of the next memory space, stored in each space. This memory architecture offers multiple possibilities for modifying the display parameters from one row to another within one and the same “screen” whilst optimizig the size of the memory used.

  • Patent number: 6601205
    Abstract: An automatic method for the generation of a logical hardware test pattern in memory circuits is based on a given physical pattern. The method includes backwards transformation from a given set of logical data patterns. Since the method is automatic, no knowledge of data scrambling inside the memory circuit is required.

  • Patent number: 6529284
    Abstract: A method and system for expanding a pixel bitmap mask. The pixel bitmap mask (102) is expanded by the use of a lookup table (104) to create an m*n bit expanded mask, where m is the depth of a screen and n is the number of pixels described by the original pixel bitmap mask (102). The expanded mask is logically ANDed with a foreground screen (106). The inverse of the expanded mask is logically ANDed with existing data in a screen buffer (108). The results of the two AND operations are logically OR'd to create a new screen buffer that is eventually sent to a printer.

  • Patent number: 6483510
    Abstract: An integrated graphic and character combining circuit for driving a display device, for example an LCD panel, allows for a configuration by which an external ROM is not necessary, reduces processing burden on the data-supplying processor, and provides a system wherein both graphic images and complete character fonts can be combined and simultaneously displayed on an LCD panel. The circuit includes a character font ROM, a character display data RAM, a graphic image data RAM, a property register, a character/graphic mixed display control circuit, an interface circuit, and a common/segment LCD driver. The character font ROM stores font data pertaining to complete characters. The character display data RAM stores addresses corresponding to the font data stored in the character font ROM. The graphic image data RAM stores graphic image data. The property register stores selection information pertaining to the graphic and character data.

  • Patent number: RE47727
    Abstract: A system for splitting a display zone of a screen is installed in an electronic device having a screen, and includes a detecting module for detecting screen pixels. A splitting processor receives a splitting instruction containing a splitting number n, and splits the display zone into a main display region and a number (n?1) of extension display regions. A total number of width pixels of adjacent ones of the main and extension display regions from left to right of the display zone equals the number of width pixels of the screen. A total number of height pixels of adjacent ones of the main and extension display regions from top to bottom of the display zone equals the number of height pixels of the screen. A display module displays two or more operating interfaces, files, and/or pages of at least one application in the main and extension display regions, respectively.
