Portable Camera Integrating GPS Navigation and Image Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional standalone digital cameras and video recorders lack the capability to incorporate location and time information with images or videos, and do not provide position navigation information when not taking pictures.
Innovation Solution
A portable digital photographing system that combines position navigation information with image information, utilizing a position information receiver, such as a GPS or Galileo receiver, and a position resolving and image digital signal processing unit to display and store this information on the device's screen, along with electronic maps and encryption for data security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional standalone digital cameras and video recorders are used, then the device structure remains simple, but the capability to incorporate location and time information with images or videos is lost
Solution Approach 1:
The patent combines a position information receiver (GPS/Galileo) with a portable digital photographing apparatus to integrate location and time information capabilities into the camera system. This merging allows the device to simultaneously function as both a photographing device and a position navigation device, resolving the contradiction between enhanced adaptability and device complexity
Solution Approach 2:
The integrated system provides multiple functions: photographing, position reception, position resolving, and information display. By making the device universal and multi-functional, it can incorporate location and time information while maintaining a unified device structure rather than requiring separate standalone devices
2Adaptability or versatility
If position navigation function is added to portable digital photographing, then location and time information can be included with images, but the device requires integration of multiple functional units
Solution Approach 1:
The patent merges the position information receiver with the photographing apparatus and integrates their processing units. The position resolving and image digital signal processing unit handles both position data and image data, reducing the need for completely separate functional units while maintaining position navigation capability
Solution Approach 2:
The processing unit is designed to be multi-functional, handling both position information processing and image digital signal processing. This universal processing approach allows position navigation function to be added without requiring entirely separate dedicated units for each function
3Ease of operation
If position information receiver is integrated with portable digital photographing apparatus, then location information can be displayed on screen, but the system requires additional processing units for position resolving
Solution Approach 1:
The patent combines the position resolving function with the existing image digital signal processing unit. This merged processing unit processes both position information from the GPS receiver and image data from the camera, enabling location information display without requiring a completely separate position resolving unit
Data Source
AI summary
Taught is a portable digital photographing system combining position navigation information and image information, wherein the position navigation information and the captured image information is combined and processed by a digital signal processing unit. The combined information then is stored in a register and displayed through an interface circuit. The portable digital photographing system can merge the location, time, and position information into the image or video. In addition, an electronic map corresponding to a position navigation information can be displayed on a display monitor.
