application example 1

[0085] (Application example 1: External output system using electromagnetic coupling)

[0086] First, refer to Figure 4A . Figure 4A is an explanatory diagram showing a structural example of a mobile terminal 300 capable of transmitting data such as an image to an external output device using electromagnetic coupling. External output devices include, for example, the car navigation system 10 and the television 20 . In addition, a display device of a personal computer and a projector that projects an image on a screen are also examples of external output devices.

[0087] like Figure 4A The signal reader 400 shown in is used, for example, to transmit data, such as images, to such an external output device. The signal reader 400 is connected to, for example, the car navigation system 10 or the television 20, or is included in the device. Signals are transmitted between the mobile terminal 300 and the signal reader 400 by using electromagnetic coupling. Accordingly, the ...

Abstract

The invention provides a signal processing apparatus, a signal processing system and a signal processing method. The signal processing apparatus generates a data signal having a signal waveform corresponding to a first bit value of a signal waveform transitioning from a high level to a low level or a signal waveform transitioning from a low level to a high level, a pre-transition signal level corresponding to a second bit value of one of a plurality of high levels and a plurality of low levels, and a post-transition signal level corresponding to a third bit value of the other.

Description

technical field [0001] The invention relates to a signal processing device, a signal processing system and a signal processing method. Background technique [0002] A mobile terminal exemplified by a mobile phone generally includes a movable member as a connection portion between an operation portion operated by a user and a display portion in which information is displayed. For example, the opening / closing structure of a folding mobile phone is a typical representative of such a movable member. In addition, recent mobile phones have image viewing functions and imaging functions in addition to calling functions and e-mail functions, so the connection part must be able to move complicatedly according to the user's usage. When using the image viewing function, for example, the user desires to point the display portion toward the user and move away the operation portion unnecessary for viewing. Therefore, there is a need for a structure in which the orientation or position of...
