Map display apparatus, map display method, and image pickup apparatus
First Claim
1. A map display apparatus comprising:
- an information recording unit which records image information including an image signal representing a picked-up image and position information representing an image-pickup position where the image signal is generated, and landmark information used to display landmark signs in a map image;
a display controller which adds an image-pickup-position mark in the image-pickup position represented by the image information to the map image, which adds landmark signs in portions represented by the landmark information to the map image, and which selectively reduces the number of types of landmark sign to be added to the map image in a number of predetermined ranges; and
a user interface unit which enables a user to select a desired one or ones of the types of landmarks signs to be displayed in each predetermined range and which enables the user to select a desired one or ones of the types of landmarks signs to be not displayed in each said predetermined range,in which the number of predetermined ranges includes a first predetermined range which is determined based on the image-pickup position, a second predetermined range determined based on a moving route in the map image, and a third predetermined range determined based on a current position in the map image, andin which each of the first predetermined range, the second predetermined range, and the third predetermined range is different from each other.

Abstract
In step ST11 of FIG. 5, a map image is displayed. In step ST12, moving-route marks are added to the map image. In step ST13, image-pickup-position marks are added to the map image. In step ST14, a current position mark is added to the map image. In step ST15, a predetermined range is determined based on an image-pickup position. Furthermore, predetermined ranges are determined based on a moving route and a current position. In step ST16, the number of types of landmark sign to be included in the map image is reduced in ranges other than the predetermined ranges. Since landmark signs which are positioned far from the image-pickup position, the moving route, and the current position and which are not important for a user are not added to the map image, map display is performed while display of the landmark signs is optimized.

5. An image pickup apparatus comprising:
-
an image pickup unit which generates an image signal representing a picked-up image; a position information generation unit which generates position information representing a position of the image pickup unit; an information recording processor which generates and records, using the position information generated by the position information generation unit when the image signal representing the picked-up image is generated as position information representing an image-pickup position, image information including the position information and the image signal representing the picked-up image; a landmark information storage unit which stores landmark information used to add landmark signs to a map image; a display controller which adds an image-pickup-position mark in the image-pickup position represented by the image information to the map image, which adds the landmark signs in portions represented by the landmark information to the map image, and which selectively reduces the number of types of landmark sign to be added to the map image in a number of predetermined ranges; and a user interface unit which enables a user to select a desired one or ones of the types of landmarks signs to be displayed in each predetermined range and which enables the user to select a desired one or ones of the types of landmarks signs to be not displayed in each said predetermined range, in which the number of predetermined ranges includes a first predetermined range which is determined based on the image-pickup position, a second predetermined range determined based on a moving route in the map image, and a third predetermined range determined based on a current position in the map image, and in which each of the first predetermined range, the second predetermined range, and the third predetermined range is different from each other.
