Problems solved by technology

[0006] Even in a GPS positioning device that can complete position measurement in a short time, for example, when the execution time that can be used in positioning processing is limited to an extremely short time, GPS satellites that can capture radio waves in the gaps of buildings, etc. When the number is small, or when the electric field strength of the radio wave is significantly weakened, etc., the positioning process may not be completed and the time has passed, and the position data may not be acquired.

Embodiment Construction

[0029] Embodiments of the present invention will be described below with reference to the drawings.

[0030] figure 1 It is a block diagram showing the whole of electronic equipment as an embodiment of the positioning device of the present invention.

[0031] The electronic device 1 of this embodiment has a photographing function for electrically photographing and saving the photographed image as image data, and a positioning function by GPS (Global Positioning System) or an autonomous navigation method, and can store images obtained by the photographing function. The data is stored in association with the location data obtained through the positioning function.

[0032] Such as figure 1 As shown, the electronic device 1 has a first processing unit 10 responsible for processing related to the photographing function and a user interface function, a second processing unit 20 responsible for processing related to the positioning function, and a power supply 35 for supplying pow...

Abstract

The invention provides a positioning device and a positioning method. When a positioning request is made, position measurement using a positioning satellite is executed, and when the position measurement is executed, positioning result data S43, S44 is obtained as position data responded to the positioning request. On the other hand, when the position measurement using the positioning satellite is not executed, position measurement result data based on the measurement of a moving direction and a moving amount is obtained as position data S42, S48 responded to the positioning request.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from prior Japanese Patent Application No. 2010-6561 filed on January 15, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] The invention relates to a positioning device and a positioning method for receiving signals from positioning satellites to measure positions. Background technique [0004] Conventionally, in electronic equipment equipped with a GPS (Global Positioning System) function, there are devices that perform position measurement intermittently every predetermined period, and devices that perform position measurement in conjunction with specific actions such as camera photography (for example, refer to Japanese Patent Laid-Open No. 2002-267734, Japanese Patent Laid-Open No. 2006-339723, and US Patent No. 6995792). [0005] In addition, in the GPS positioning device, in order to quickly complete the position me...
