Description

便携信息终端技术领域本发明涉及便携信息终端,涉及至少能够处理两种信息源的便携信息终端。 The portable information terminal Technical Field The present invention relates to a portable information terminal, to a portable information terminal capable of processing at least two types of information source. 特别是涉及提高显示性能及操作性的技术,更具体来说,涉及能够将例如地面数字广播电视的广播电视图像画面及移动电话的通信信息画面等画面形状不同的信息源在整个图像显示单元上有效地进行显示、并还能够以双手舒适地进行输入操作的便携信息终端。 Particularly to improve the performance and operability of the display technology, and more particularly, relates to a different communication information such as a broadcast television screen picture plane of terrestrial digital television broadcasting and mobile phone, and the like in the shape of the picture information source on the entire image display unit effectively for display, and can also be performed with both hands portable information terminal input operation comfortably. 背景技术近年来,数字移动通信中的数据通信速度正不断向宽频带及高速化发展。 BACKGROUND In recent years, digital mobile communication data communication speed is constantly in the broadband and high-speed development. 在移动电话及PDA (Personal Digital Assistant ,个人数字助理)等便携信息终端中,逐渐能够方便地收发包含文字及图像等在内的信息源(数据)。 In the mobile phone and PDA (Personal Digital Assistant, a personal digital assistant) and other portable information terminals, gradually can be conveniently comprise a transceiver including text and images sources (data). 即使对于以往是利用个人计算机(PC)浏览的因特网的网站等,也逐渐能够从便携信息终端进行访问。 Even for the past browsing Internet sites such as using a personal computer (PC), are also increasingly able to access it from portable information terminal. 现在还存在许多便携终端用的网站。 Now there are many portable terminal site. 与之相应, 装在便携信息终端上的液晶显示装置(LCD)等图像显示单元也不断向全彩色、 大屏幕、高图像质量方向发展。 Correspondingly, the liquid crystal is mounted on a portable information terminal display device (LCD), etc. The image display unit continues to evolve to full-color, large-screen, high-quality image direction. 再有,经由通信线路的内容传送技术也在不断发展,用户也逐渐能够使便携信息终端下载并执行具有高级GUI (Graphic User Interface图形用户接口)功能的内容或程序数据。 Further, via the communication line of the content delivery technology is evolving gradually enable the user to download and execute the mobile information terminal (Graphic User Interface Graphical User Interface) function or program content data having advanced GUI. 例如,能够下载作为内容数据的游戏软件等,还能够通过操作便携信息终端来玩下载的游戏。 For example, game software can be downloaded as the contents data and the like, can also play a downloaded game by operating the portable information terminal. 作为代替现在模拟广播电视的新的广播电视方式,正在开发地面数字广播电视。 As a new way to replace the current analogue television broadcasting radio and television, we are developing terrestrial digital broadcast television. 在地面数字广播电视的技术标准即ISDB — T (Integrated Services Digital broadcasting—Terrestrial,地面综合业务数字广播电视)中,调制方式采用了使用多个载波的正交频分多路复用(OFDM),还能够抑制因大楼造成的反射等而形成的多传输路径(多路径)产生的重影。 Technical standard for terrestrial digital television broadcasting, i.e. ISDB - T (Integrated Services Digital broadcasting-Terrestrial, integrated services digital terrestrial television broadcasting), the modulation mode using a plurality of carriers orthogonal frequency division multiplexing (OFDM), ghost can be suppressed multiple transmission paths (multi-path) caused due to reflection or the like formed by building produced. 在ISDB — T中,可以举出一大特征是即使在移动终端也能够稳定进行接收。 In ISDB - T can also include a feature is capable of stable reception even in a mobile terminal. 因而,也准备开展使用PDA及移动电话等移动终端接收地面数字广播电视的业务。 Thus, also prepared to carry out the use of PDA and mobile phones and other mobile terminal receiving digital terrestrial television broadcasting business. 另外,还在研究有效利用宽带传输路径的数据广播电视,与经由一般通信线路下载的内容相比,是更丰富更高级的内容传送业务,对此也寄与很大的期望。 In addition, data is also studying the effective use of radio and television broadband transmission path, compared with the general content via the communication line to download, it is richer and more advanced content delivery business, which also sent with great expectations. 可以预料,今后能够处理经由一般通信线路的信息源及经由地面数字广播电视等的信息源的至少两种信息源的新型便携信息终端将迅速普及。 It is anticipated that in the future be able to handle at least two sources of information via a communication line of a general information source and the information source via the terrestrial digital television broadcasting or the like to a novel rapid spread of portable information terminal. 但是,为了使得在便携信息终端中能够处理经由一般通信线路的信息源及地面数字广播电视的信息源那样的两种不同的信息源,则存在以下的问题。 However, in order that the portable information terminal capable of handling two different sources of information such as a source of information via the information source is typically communication lines and terrestrial digital television broadcasting, the following problem exists. 第一个问题是关于显示画面的问题。 The first issue is the issue of the display. 关于这个问题,下面参照图13进行说明。 On this issue, 13 will be described below with reference to FIG. 图13所示为一般的移动电话的外形图。 Figure 13 shows a general external view of a mobile telephone. 如图13所示,一般的移动电话上设置显示画面IO及在它下部的操作按键单元。 13, is provided a display screen and an operation key unit IO at its lower portion on conventional mobile phones. 一般,移动电话的显示画面是竖长形。 In general, the display screen of the mobile phone is vertically long shape. 再有,经由一般通信线路而得到的网站的画面形状也大致是竖长形的画面形状。 Further, the general shape of the picture via the communication line sites also obtained substantially vertical elongate shape of the picture. 与此相反,关于利用地面波数字广播电视进行播放的图像,为了求得与以往的模拟广播电视及电视接收机的通用性,则采用横长形的画面形状。 In contrast to this, the image on playback using the digital terrestrial television broadcasting, in order to obtain the conventional analog television broadcasting of a television receiver and versatility, the use of horizontal elongated shape of the picture. 因而,在以往的移动电话所具有的竖长形显示画面10上,在使它显示利用数字广播电视的图像时,不能在整个显示画面上显示图像。 Thus, the display screen 10, when it television image display using digital broadcasting, an image displayed on the entire display screen in a conventional mobile phone has a vertically long shape. g卩,如图13所示, 就变成使图像显示单元IO的一部分10a来显示图像。 g Jie, 13, becomes a part of the image display unit 10a to display an image of the IO. 图13中,图像显示单元10的区域10b不能用于图像显示,成为无效区域。 In FIG 13, the image display area unit 10 can not be used for image display 10b, become ineffective region. 最好能够在整个图像显示画面IO上进行显示。 Preferably the entire image can be displayed in the display screen IO. 作为与便携信息终端的显示画面有关的以往技术,在日本专利特开平ll一55724号公报中揭示了一种移动电话,它具有通过使显示画面单元IO旋转而能够以一行显示长的字符串的显示器。 A display screen associated with the portable information terminal prior art, discloses a mobile telephone in Japanese Laid-Open Patent Publication 55,724 a No. ll, having one line and capable of displaying a display screen by means of the long string rotation IO monitor. 上述公报中揭示的形态电话的显示单元是只显示字符串,难以适用于显示图像的移动电话。 Morphology telephone display unit disclosed in the above publication is a string of only difficult to apply to a mobile phone displays an image. 第二个问题是关于操作性的问题。 The second issue is the issue of operability. 在现在的便携信息终端中,有的能够下载并执行游戏内容。 In today's portable information terminal, some are able to download and execute the game content. 游戏操作中必须不可少的是要快速地进行按钮输入,例如对于游戏专用机的控制器是这样设计的,使其能够用双手快速地进行按钮输入。 Game operation must be essential to quickly enter a button, for example, gaming machine controller is designed such that it can be quickly button input with both hands. 若开始利用地面数字广播电视提供的数据广播电视业务,则能够下载更丰富、 更高级的内容,要求更进一步提高其输入操作性。 If the data began to use radio and television services provided by terrestrial digital television broadcasting, it is able to download richer, more advanced content, requires further increase their input operability. 但是,在一般的移动电话中,对小型化的要求更迫切,由于通常仅仅只要能进行电话号码的输入及画面的滚动即可,因此按键操作单元设计成适合于单手拿住的细长形状,使得容易用单手进行按键输入操作。 However, mobile phones in general, more stringent requirements for miniaturization, since usually only as long as the input for scrolling a screen and a telephone number, and therefore the key operation unit designed to be suitable for single hand elongated shape live It makes it easy for the key input operation with one hand. 因而,难以用双手握住, 难以用双手快速地进行输入。 Accordingly, it is difficult to hold with both hands, it is difficult to quickly input with both hands. 虽然今后也需要容易用单手拿住、容易操作的操作性,但除此之外,也要求有用双手舒适而容易快速输入的结构。 Although the future is also likely to need to live with a single hand, easy maneuverability, but in addition, also requested a useful hands comfortable and easy to quickly enter the structure. 本发明正是为了解决以上的问题而提出的,归纳起来有以下的目的。 The present invention was made to solve the above described problems, summed up in the following purposes. 本发明的目的在于提供能够应对两种不同信息源的新型便携信息终端。 Object of the present invention is to provide a novel portable information terminal can cope with two different sources of information. 更具体来说,是提供即使取得的图像数据的长宽比等画面形状不同时、也能够在整个显示画面上有效地进行显示的便携信息终端,以及提供除了以往的单手操作的操作性以外,还将加上用双手快速输入的操作性而具有这两种操作性的便携信息终端。 More specifically, even if the shape of the picture aspect ratio to provide to provide the acquired image data and the like are different, it is possible to efficiently perform the portable information terminal is displayed on the entire display screen, and in addition to the operability of the conventional one-hand operation outside , also operatively coupled with both hands with fast input portable information terminal having two operability.
