DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an electronic device with a sensor, and more particicularly to an electronic device which displays information corresponding to a value measured by the sensor.
BACKGROUND ART
Conventionally, an electronic device is known which includes a pressure sensor or temperature sensor and displays a value measured by the sensor. For example, an altimeter or sounding machine displays an altitude or depth of water based on pressure data measured by a pressure sensor. An electronic thermometer or clinical thermometer displays on a display unit atmospheric temperature data or body temperature data measured by a temperature sensor incorporated therein.
The conventional electronic device with a sensor, as described above, displays only a value measured by the sensor, and. cannot display other information based on the measured value.
DISCLOSURE OF THE INVENTION
The present invention has been made to solve the aforementioned drawback of the conventional device, and its object is to provide an electronic device with a sensor which can display not only a value measured by the sensor but also information based on the measured value.
To achieve the above object, according to the present invention, there is provided an electronic device comprising a sensor; a sensor driving circuit for driving the sensor, thereby obtaining data of measurement values; a display capable of performing color display; a storage unit for storing data of display colors respectively corresponding to the data of the measurement values obtained by the sensor driving circuit; a reader for reading data of a display color corresponding to data of a measurement value obtained by the sensor driving circuit from the data of display colors stored in the storage unit; and a display controller for driving the display to perform display in a color corresponding to the data of the display color read by the reader.
With the above structure, the electronic device with a sensor of the present invention can display information corresponding to values measured by the sensor in colors associated with the values. Thus, since information other than the measured value can be displayed, and the utility of the device is increased.

BEST MODE OF CARRYING OUT THE INVENTION
A preferred embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a front view of an electronic watch to which the present invention is applied.
As shown in FIG. 1, watch bands 32a and 32b are attached to upper and lower sides of a watch case 31. A display 15 is arranged in a central portion of the watch case 31 under a glass 33. A mode change switch K1 and a temperature measurement switch K2 are arranged in a lower portion of the surface of the watch case 31. A maker set switch K3 and a time adjustment switch K4 are arranged on a right side of the watch case 31. A detection groove 34 is formed in an upper left portion of the watch case 31 and a temperature sensor 21 of a radiation thermometer is arranged in an inner portion of the detection groove 34.
FIG. 2 shows a circuit structure of the electronic watch as described above.
Referring to FIG. 2, the electronic watch comprises a control unit 11, a RAM 12, a ROM 13, a display driver 14, a display 15, an oscillator 16, a freq
