    Abstract: This invention provides a mechanism for making a doctor surely follow correct procedures in which the doctor confirms diagnosis information obtained by computer processing after he or she has completed interpretation. A medical diagnosis support apparatus executes diagnosis processing for acquiring medical diagnosis information from an image to be interpreted by computer processing. The medical diagnosis support apparatus accepts interpretation information as an interpretation result of the image to be interpreted, which information is input by, for example, a doctor. The medical diagnosis support apparatus calculates a degree of matching between the diagnosis information and interpretation information, and permits to present the diagnosis information acquired by the diagnosis processing when the calculated degree of matching exceeds a predetermined threshold.

  • Patent number: 5852428
    Abstract: Each of a plurality of segment drivers for driving a liquid crystal display panel used in an electronic device includes a display data memory corresponding to a display image plane. The display memory is supplied with an X address and Y address from an address register so that the data write area thereof can be specified. A control device of the electronic device outputs address data and display data to a connection bus when data is stored into the display memory, and the segment driver writes transfer data into an addressed area when it is determined that the write-in process is effected for the segment driver itself by decoding address data by use of a decoder. When data stored in the display memory is displayed, the Y address is automatically incremented in synchronism with a common signal by an increment circuit, and data of one line specified by the Y address is simultaneously read out from an output port of the display memory, converted into a segment signal via a latch circuit and output.

  • Patent number: 5850231
    Abstract: An electronic device maintains data utilizing a ferroelectric memory, not requiring a backup power source voltage. Data such as schedule data and telephone number data is stored in a ferroelectric RAM which switches between a dynamic mode and a nonvolatile mode. When a clock mode is designated by a "CLK" key, a memory control circuit causes the ferroelectric RAM to be switched to the nonvolatile mode to maintain the data stored therein. When a schedule mode or a telephone mode is designated by means of a "Sch" key or a "Tel" key, the ferroelectric RAM is switched to the nonvolatile mode to write/read data therein/therefrom. When it is detected that a battery voltage is lowered or the battery is removed from the electronic device, the ferroelectric RAM is switched to the nonvolatile mode to protect the stored data.

  • Patent number: 5663745
    Abstract: An electronic device has a plurality of segment drivers for driving a liquid crystal display panel and a control unit. Each of the segment drivers has a display memory for storing display data. The control unit outputs address data and display data when the control unit produces an image to be displayed on a display. In case the segment drivers receive address data, each segment driver determines whether it is addressed or not by decoding a data piece of the address data. Then, in case the segment drivers are addressed, they write the input display data in the display memory on the basis of the address data.

  • Patent number: 5444458
    Abstract: A system memory in the electronic device has a display data memory area, and when a CPU accesses directly to the system memory, the liquid crystal display control section (LCDC) monitors whether or not address data is directed to the display data memory area. In the case where the address data associated with display data is directed to the display memory area, the LCDC also sends the display data and the address data to the display driving circuit. The display driving circuit comprises a VRAM, in which the display data is stored in a predetermined memory location in accordance with the received address data, and the stored data is displayed on the LCD.
