ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a display control apparatus and method applied to an automatic teller machine set in a financial institution such as a bank.
An automatic teller machine set in a financial institution such as a bank has a liquid crystal monitor having a touch panel. A transaction selection screen, a password input screen, or an amount input screen is displayed on this liquid crystal monitor. The transaction selection screen receives the transaction selected by the user. The password input screen receives input of the password of the user. The amount input screen receives input of the amount of deposit/withdrawal from/to the user.
Assume that the transaction selection screen is displayed on the liquid crystal monitor. Items such as “deposit”, “withdrawal”, “transfer”, and the like are displayed on this transaction selection screen. When the user designates the display position of a predetermined item through the touch panel, a transaction corresponding to the designated display position, i.e., transaction of a predetermined item is received. Such a user interface for receiving input from the user is formed in the automatic teller machine by combining the touch panel and liquid crystal monitor.
Contents to be input through this user interface include secret information such as a password. Users must sometimes wait their turns to use the automatic teller machine. In such a case, the next user at the automatic teller machine normally waits for his/her turn behind the previous user who is using the automatic teller machine. When the previous user is using the automatic teller machine, the next user may look at the liquid crystal monitor, and consequently, the secret matters may leak.
BRIEF SUMMARY OF THE INVENTION
It is an object of the present invention to provide a display control apparatus and method capable of preventing contents input through a liquid crystal monitor from leaking to a third party.
According to an aspect of the present invention, there is provided a display control apparatus comprising liquid crystal display means for displaying and switching a plurality of operation screen to display a desired operation screen in accordance with a predetermined input, input means for inputting the predetermined input arranging on said liquid crystal display means, and field angle control means for, when the operation screen to be displayed on the liquid crystal display means in accordance with the predetermined input inputted by the input means corresponds to a specific operation screen for receiving input of specific data, controlling a field angle of the liquid crystal display means to a predetermined field angle.
According to another aspect of the present invention, there is provided a display control method comprising the first step of inputting a predetermined input, and the second step of, when an operation screen to be displayed on liquid crystal display means in accordance with the predetermined input inputted in the first step corresponds to a specific operation screen for receiving input of specific data, controlling a field angle of the liquid crystal display means to a predetermined field angle.
Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
