Problems solved by technology

[0004] However, in information equipment using the input device disclosed in JP-A-7-134630, it is very difficult to drive it for a long time with a battery
Also, it is very difficult to achieve small size and light weight due to the need to use input indicators
In this way, it is difficult to actually install the input device disclosed in JP-A-7-134630 on a portable information device.

Embodiment Construction

[0069] Hereinafter, embodiments suitable for the present invention will be described in detail with reference to the accompanying drawings. In addition, the content of this invention is not limited to the Example demonstrated below. In addition, all the configurations described below are not limited to the essential configuration requirements of the present invention.

[0070] 1. Information device

[0071] An outline of an example of the configuration of an information device is shown in FIG. 1 .

[0072] This embodiment relates to an information device having a personal authentication function and an information display function. As such an information device, it is important to have functions such as a personal computer (PC), a personal digital assistant (PDA), an IC card, and a mobile phone, and to have an information display unit such as a display. Here, the information device can be applied to, for example, an IC card including an integrated circuit (IC) as a portable...

Abstract

In an information device (10), a fingerprint image capture section (20) captures a fingerprint image of an operator. When a fingerprint image captured by the fingerprint image capture section (20) is referred to as a first fingerprint image and a fingerprint image captured at a given time interval after the first fingerprint image is captured is referred to as a second fingerprint image, a comparison section (30) compares minutiae points of the first and second fingerprint images extracted by a minutiae point extraction section (60). An image generation section (40) generates image information which is changed while reflecting the comparison results of the comparison section (30). A display section (50) displays an image based on the image information generated by the image generation section (40). The information device (10) may be provided with a check section (110), and display control by the display section (50) may be performed after a fingerprint image is checked by the check section.

Description

technical field [0001] The present invention relates to an information device and a display control method. Background technique [0002] In an information device having a display unit, various controls (operations) are performed by specifying a position on a menu screen and moving a pointer on the screen. Such a control instruction can be implemented by specifying coordinate positions on a panel having conductors arranged in a matrix, for example, by using an input indicator having a synchronous circuit (for example, refer to JP-A-7-134630). In this case, regarding the X direction or the Y direction arranged in a matrix, whichever one passes the current to the two conductors, the voltage generated by the synchronous circuit inside the input indicator and the magnetic coupling of the conductors, Specifies the specified position on the panel. The information device is controlled using the position specified in this way as instruction information. [0003] However, with the...
