Abstract

The present invention was made to solve the problem that users cannot check e-mail containing an attached image at a glance on conventional portable terminals. According to the present invention, there is provided a portable terminal that can display the e-mail text overlapped upon the attached image in an easy-to-see manner, and hence improve its usability as a mail receiving terminal.

An image processing/output means converts the attached image data into image data of a size corresponding to that of the display area, and processes the attached image data to correct either of the brightness and contrast thereof. Further, a character setting/output means sets display color of the mail text according to the chromaticity of the image data so that the mail text will be overlapped upon and displayed with the set display color against the background of the processed image.

Claims

1. A portable terminal comprising:

a receiver for receiving image data and character data transmitted in association with each other;

an input unit for inputting instructions;

a control unit for generating display data from the received image data and the character data; and

a display unit for displaying the display data, wherein

said control unit generates the display data in such a manner that the associated character data are overlapped upon and displayed against the background of the image data.

2. A portable terminal according to claim 1, wherein the character data is character data of the e-mail text and the image data is image data attached to the e-mail.

3. A portable terminal according to claim 1 or 2, wherein said control unit converts the received image data into image data of a size corresponding to that of the display area of said display unit to generate the display data.

4. A portable terminal according to claim 1 or 2, wherein said control unit processes the received image data to correct either or both of the brightness and contrast of thereof to generate the display.

5. A portable terminal according to claim 1 or 2, wherein said control unit sets display color of the received character data according to the chromaticity of the image data to generate the display data.

6. A portable terminal according to claim 1 or 2, wherein said control unit makes two or more display colors of the received character data changeable in accordance with user.s operation on said input unit.

7. A portable terminal according to claim 1 or 2, wherein said control unit converts the received image data into image data of a size corresponding to that of the display area of said display unit, and processes the received image data to correct either or both of the brightness and contrast thereof to generate display data.

8. A portable terminal according to claim 7, wherein said control unit sets display color of the received character data according to the chromaticity of the image data to generate the display data.

9. A portable terminal according to claim 1 or 2, wherein when two or more kinds of image data are received, said control unit makes the image data to be displayed as the background changeable in accordance with user.s operation on said input unit.

10. A portable terminal according to claim 1 or 2, wherein said control unit makes the received image data changeable in scale when they are converted into image data of a size corresponding to that of the display area of said display unit so that part of the image data not to be displayed on the display area at the time can be displayed by scrolling.
