Benefits of technology

[0009] Thus, picked images are selected on the predetermined condition and stored on a segment-by-segment basis. Therefore, the stored picked images are homogeneous from one segment to another. As a result, images can be efficiently acquired so that uncomfortable feeling given to users who view images picked up is lessened.
[0041] In this case, it is preferable that the displaying means should narrow the scope of display of corrected picked images so that loss of image information is reduced in displayed corrected picked images.

Problems solved by technology

In this form of service, however, information about any point cannot be viewed.
However, when there are a plurality of pieces of data of images picked up in a continuing district on different occasions in a database, a problem arises.
Users who receive delivered images in the database and continuously view them can feel something is wrong because of differences in image pickup environments such as weather.

first embodiment

[0075]FIG. 1 is a conceptual diagram schematically illustrating an image delivery system in a first embodiment of the present invention. A vehicle 1 (probe car) running on a road 2 is provided with an omnidirectional image pickup function that allows the image of the 360 degree surroundings of the vehicle itself to be picked up, and with a communication function for wireless communication with base stations 3. The vehicle 1 transmits a picked image 6 picked up by the omnidirectional image pickup function and the image pickup information of the picked image 6 to an image server 5 through a base station 3 and a base station network 4 to which the base station 3 is connected. The image pickup information includes: the position in which the vehicle was when the picked image 6 was picked up; image pickup time, the direction (azimuth) in which the vehicle was running when the image was picked up; the running speed at which the vehicle 1 was when the image was picked up; and the like. The ...

second embodiment

[0155] Next, description will be given to a second embodiment of the present invention only with respect to differences from the first embodiment. In this embodiment, the constitution of the fixed terminal 36 and the in-vehicle terminal 37 is a major difference from the first embodiment.

[0156]FIG. 12 illustrates the configuration of the fixed terminal 36 and the in-vehicle terminal 37 as in-vehicle equipment. This communication device comprises a radio antenna 71, a wireless communication device 72, a GPS sensor 74, and a control computer 70. The wireless communication device 72 wirelessly communicates communication data through a wireless base station connected with a wide area network 8 using the radio antenna 71. The GPS sensor 74 is the same as the GPS sensor 22 illustrated in FIG. 2.

[0157] The control computer 70 has a sensor control unit 76, a communication control unit 73, an information processing unit 75, and a user interface unit 77. The sensor control unit 76 periodical...

third embodiment

[0175] Description will be given to a third embodiment of the present invention. A difference of this embodiment from the second embodiment is as follows: when the up button 84 is pressed, the image display program may control the orientation of the image to be displayed next based on the orientation in which the image was when it was picked up.

[0176]FIG. 19 is a drawing illustrating a case where an effect of this embodiment is characteristically produced. It will be assumed that the image display program presently displays an image picked up at the portion of a curved road where an arrow is present, and the orientation of the displayed image agrees with the direction of the arrow. When the up button 84 is pressed in this case, point A the picked image of which is present in the image server 5 comes in the fan-shaped search region illustrated in FIG. 16. Therefore, the image display program displays the picked image of point A with its orientation agreeing with the direction of the...

Abstract

Images are efficiently collected or delivered so that uncomfortable feeling given to users who view picked images picked up at vehicles and delivered by an image server is lessened. An image server is so constructed that the following operation is performed: the picked image of the surroundings of a vehicle, picked up with a camera mounted on the vehicle, and the image pickup information of the picked image, including information about the image pickup point, are stored on a storing medium; and picked images stored on the storing medium are delivered to users who view received picked images. One is selected from among picked images inputted from a vehicle with respect to each of areas to which the image pickup points of those picked images belong based on the image pickup information and a predetermined selection condition. The selected picked image is stored on the storing medium.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application is a continuation of an international patent application No. PCT / JP2004 / 008112 filed on Jun. 10, 2004 designating the United States of America, and is based on Japanese Patent Application No. 2003-167806 filed on Jun. 12, 2003, the contents of which are incorporated herein by reference in its entirety.FIELD OF THE INVENTION [0002] The present invention relates an image acquisition device that picks up the image of the surroundings of a vehicle, an image server that delivers images picked up, and an image display terminal that displays the images delivered by the image server. BACKGROUND OF THE INVENTION [0003] There are known services for transmitting the information about traffic jams and the like to remote persons. In such services, stationary cameras are installed on roadsides, and the images of roads picked up by these cameras are delivered to persons who request them. For example, a service called MONET (registered ...
