Abstract
When of a map or the like is displayed on the basis of an information read from a recording medium, the display can be preferably performed with little waiting time even when the apparatus is activated or when the recording medium is replaced. For example, a predetermined information is saved in a non-volatile memory (18) immediately before the power supply is turned off or the recording medium is replaced, and the predetermined information saved in the non-volatile memory (18) when the power supply is turned on or a now recording medium is loaded to perform a desired display process based on the predetermined information thus read.
Claims21
A display method comprising the steps of:
- saving a predetermined information in a non-volatile storage means immediately before a power supply is turned off;
- reading said predetermined information from said nonvolatile storage means when said power supply is turned on;
- and
- performing a desired display process based on the read predetermined information.

A display method comprising in which:
- when an image information read from a first recording medium is stored in a predetermined storage means and a stored image is displayed,
- the image information read from said first recording medium is saved in said storage means, when said first recording medium is replaced with a second recording medium, until said second recording medium is loaded and a new image information is read from said second recording medium;
- and
- an image is displayed based on the saved image information.
1 more element
A method of storing image information, wherein when a recording medium storing information for displaying an image is replaced, a new image information is read from said recording medium immediately after said recording medium is replaced regardless of whether a means for displaying an image is activated or not and said read image information is stored in a predetermined storage means.
A display apparatus comprising:
- a power supply control means for controlling turning on/off of a power supply;
- a means for reading a recording medium for a predetermined information;
- a non-volatile storage means for saving the predetermined information read by said reading means;
- a display processing means for generating a display signal based on a predetermined information read by said reading means or a predetermined information saved in said non-volatile storage means;
- and
- a display means for displaying the display signal generated by said display processing means, wherein
- the predetermined information read by said reading means is saved by said non-volatile storage means immediately before said power supply control means turns the power supply off;
- and
- a desired display process based on the predetermined information saved in said non-volatile storage means is performed when said power supply control means turns the power supply on.
6 more elements
A display apparatus comprising:
- a means for reading a recording medium for a predetermined information;
- a detection means for detecting a loading and a removal of a recording medium loaded on said reading means;
- a storage means for saving a predetermined information read by said reading means;
- a display processing means for generating a display signal based on the predetermined information saved in said storage means;
- and
- a display means for displaying a display signal generated by said display processing means, wherein
- when said detection means detects the replacement of said recording medium while said display processing means is not performing the process of generating the display signal, a predetermined information is read by said reading means from a newly loaded recording medium and is saved in said storage means.
4 more elements
A navigation apparatus comprising;
- a power supply control means for controlling turning on/off of a power supply;
- a position measuring means;
- a means for reading a map information and an information associated therewith from a recording medium;
- a read control means for causing said reading means to read an information of a map in the vicinity of a position measured by said position measuring means;
- a non-volatile storage means for saving a predetermined information read by said reading means;
- and
- a display processing means for generating a display signal of a map based on a predetermined information read by said reading means or a predetermined information saved in said non-volatile storage means, wherein:
- the predetermined information read by said reading means is saved in said non-volatile storage means immediately before said power supply control means turns the power supply off;
- and
- a process of generating a display signal based on the predetermined information saved in said non-volatile storage means is performed when said power supply control means turns the power supply on.
7 more elements
A navigation apparatus comprising:
- a position measuring means;
- a means for reading a map information and an information associated therewith from a recording medium;
- a detection means for detecting a loading and removal of a recording medium loaded on said reading means;
- a read control means for causing said reading means to read an information of a map in the vicinity of a position measured by said position measuring means;
- a storage means for saving predetermined an information read by said reading means;
- and
- a display processing means for generating a display signal of a map based on a predetermined information saved in said storage means, wherein
- when said detection means detects a replacement of said recording medium while said display processing means is not performing a process of generating a display signal, a predetermined information is read by said reading means from a newly loaded recording medium and is saved in said storage means.
