Problems solved by technology

Therefore, it is difficult to apply a common display control circuit to conventional mobile phones and TV phones
[0005] If the display control circuit were made for the videophone so that this problem would be eliminated it would cause a new problem that even when the videophone is not in use the videophone function still consumes power
That is, if the display control circuit of the TV phone is used for still image data display, it is difficult to stop the power supply to the TV phone function even when the TV phone function is not used, for example, even in the case of conversational communication and e-mail
As a result, the display control circuit wastes power
[0006] In addition, if a mobile phone without a videophone function and a mobile phone with a videophone function are developed independently of each other in order to avoid the above-mentioned problem of common use, the display will be lost in these mobile phones because the structure of the display control circuit is different. Commonality of control circuits, therefore, double R&D will lead to increased cost and waste of resources

[0066] Next, we will refer to Figure 4 and Figure 5 , an information communication terminal having a videophone function according to a second embodiment of the present invention will be described.

[0067] Figure 4 A block diagram showing the structure of an information communication terminal having a videophone function according to a second embodiment of the present invention. Figure 5 is shown Figure 4 A block diagram showing details of the image data processing circuitry. The information communication terminal of this embodiment shown in these figures is a modification of the first embodiment described above, and a memory 40 for storage is added to the videophone processing section 20 . Other than that, the structures of other components are the same as those in the first embodiment. Therefore, the same components are denoted by the same reference numerals as in the first embodiment, and their detailed descriptions are omitted.

Abstract

An information communication terminal with a TV telephone function, includes a display data generating section (1), a TV telephone processing section (2), a display unit (3), a first switch (4) and a control section (7). The display data generating section generates first display data in a general use mode in which a TV telephone function is not used. The TV telephone processing section generates second display data in a TV telephone use mode in which the TV telephone function is used. The display unit displays inputted display data. The first switch is provided among the display data generating section, the TV telephone processing section and the display unit. The control section controls the first switch to connect the display data generating section and the display unit in the general use mode such that the first display data is supplied to the display unit and to connect the TV telephone processing section and the display unit in the TV telephone use mode such that the second display data is supplied to the display unit.

Description

technical field [0001] The present invention relates to an information communication terminal, more specifically, to a mobile information communication terminal with a videophone function. Background technique [0002] Recently, in mobile information communication terminals such as cellular phones and PHSs, remarkable developments have been made in performance and functions, and information communication terminals generally have functions such as electronic mail and Internet in addition to basic functions such as conversational communication functions. Additional features such as browser functionality. Furthermore, as known in Japanese Unexamined Patent Applications (JP-A-Heisei 10-065780 and JP-P2002-094629A), in recent years, information communication terminals having a function of a so-called videophone have been provided, which combine image data with Communication sounds are sent and received together. [0003] Incidentally, the videophone function of the landline tel...
