Abstract

PROBLEM TO BE SOLVED: To improve the reliability of measurement data or bearing data recorded with a photographing image by adding information for discriminating which data is latched data among plural recorded data and recording that to a recording medium. SOLUTION: A storing means 39 rewrites the data to be the latest data obtained from a GPS receiver 32 or a bearing sensor 33, and stores the latest data. A latch means inhibits the data stored in the means 39 from being rewritten. A CPU 31 adds the information discriminating which data is the one latched by the latch means and records that on a photographic film. Thus, when the measurement data recorded with the photographing image are confirmed later, it becomes clear that the data is the measurement data or the bearing data obtained at a photographing place, or the measurement data or the bearing data latched at a place other than the photographing place.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera capable of recording various kinds of information together with a photographed image.
Global Positioning System (Global Position) that receives information transmitted from PS satellites and determines the position of the receiver
ioning System, hereinafter simply referred to as GPS. ) And various sensors and the like, the present invention relates to a camera capable of recording shooting condition-related information such as geodetic latitude and longitude of a place where a camera shoots and time at the place together with a shot image on a recording medium.

[0002]

2. Description of the Related Art In recent years, positioning information such as latitude, longitude, altitude, and time is obtained from a GPS satellite used in a car navigation system as information related to photographing by a camera, and this information is recorded on a photographic film together with an image. A camera is proposed.

As such a camera, for example, the geodesic latitude and longitude of the photographing location is calculated from the positioning data such as latitude, longitude and altitude obtained from the GPS receiver, and the discriminating means is based on the geodesic longitude and latitude. A camera for selecting a plurality of place names stored based on the number (see Japanese Patent Laid-Open No. 3-247081)
Alternatively, a camera (see Japanese Patent Laid-Open No. 4-70724) has been proposed which automatically records positioning data obtained from a GPS receiver together with a captured image on a recording medium such as a photographic film or a memory. Such a camera (Japanese Patent Laid-Open No. 3-24708)
No. 1 and Japanese Patent Application Laid-Open No. 4-70724), a place where radio waves are hard to reach, for example, in the shadow of an obstacle or inside a building,
Since the positioning data cannot be captured by the GPS receiver at the time of shooting in the basement or the like, the shooting location corresponding to the shooting frame at that location could not be recorded.

In order to solve such a problem in a place where it is difficult for radio waves to reach, the reception state is discriminated by the reception state discriminating means, and the data already stored in the storage means when the reception is impossible is recorded in a photographic film or a memory. Camera (Japanese Patent Laid-Open No. 6-6
No. 7282) is proposed. A camera with such an information recording function (see Japanese Patent Laid-Open No. 6-67282)
In order to improve the accuracy of positioning data recorded in
Differential G which is said to be the error number m from the S receiver
PS (hereinafter, referred to as DGPS) is becoming popular. Further, the present applicant has proposed a camera that additionally records data of a sensor (for example, a direction sensor etc.) other than the positioning data from the GPS receiver (Japanese Patent Application No. 6-26901).
No. 7).

[0005]

However, even if the camera described above (see Japanese Patent Laid-Open No. 6-67282) is equipped with a DGPS receiver in order to improve the measurement accuracy of the positioning data, the location can be changed. However, in the case of shooting, even if the positioning data at the previous shooting location, the positioning data when the power switch is turned on, etc. are imprinted, the geodetic data will have too large an error from the geodetic latitude and longitude. Specifically, it is not possible to distinguish whether such positioning data with a large error is the positioning data recorded at the receiving place when the data is referenced later, or the positioning data recorded as a reference at the unreceivable place. The positioning data that can be read from the medium is significantly different from the geodetic latitude and longitude of the shooting location, which makes the data reliability extremely poor.

Further, a camera (see Japanese Patent Application No. 6-269017) for recording data by adding data of a sensor (for example, a direction sensor) other than the positioning data from the GPS receiver,
The azimuth sensor that detects the earth's magnetism causes an error in the azimuth data due to the inclination of the sensor with respect to the direction of the magnetic force line, and thus the reliability of the positioning data recorded on the recording medium is reduced.

An object of the present invention is to solve the above technical problems,
It is an object of the present invention to provide a camera with improved reliability of positioning data or orientation data recorded together with a captured image.

[0008]

The above object is achieved by the following constitution.

In order to make it easier to receive the antenna part 2a of
A azimuth sensor (not shown) for detecting the azimuth of the camera body is arranged on the upright portion 2 in a desired orientation with respect to the earth's magnetism.

As shown in FIG. 2, the processing circuit section 3 selects the photographing information so as to display desired information on the display section 5 for displaying each information to be recorded and the photographing information such as the photographing mode. An operation unit 6 and a battery cover 7 for the power supply battery are provided.

The operating portion 6 has a function of giving a latch instruction particularly in this embodiment, and as shown in FIG.
