چکیده
The latest progress of IGN's project on digital cameras, that has begun in 1991, are described. The features of the present prototypes are presented. The results of the first attempt to use digital images in IGN production lines are given, either in color with an orthophoto on the city of Rennes, and in panchromatic with a survey over the city of Saumur for the production of IGN's BDTOPO®. The trends of the project are then briefly assessed.

Current Status of the Digital Camera IGN
The current state of IGN's project on digital cameras, that has begun in 1991, is described. The features of the present prototypes are presented. The results obtained on two surveys in winter and in summer are described and commented. Since these results have convinced IGN's users of the interest of aerial digital data, these cameras will start in 1997 to be used for IGN production purposes.
متن کاملA Proposed Simple Teleradiology System Using a Digital Camera
Background & Aims: Teleradiology as an efficient way for avoiding unnecessary transfer of patients to special medical centers requires the images with digital format. However, in some developing countries, including Iran, imaging is being done using non digital devices. In such cases, changing analog images into digital ones can solve the problem. The method which is nowadays used for digita...

متن کاملDiagnostic Accuracy of Digitized Images Using Different Resolution Settings of Digital Camera in Detection of Proximal Caries
Objective: When none of digital systems and scanners is accessible and it is essential to have digitized images of conventional radiographs, digital cameras can be used. The Aim of this study was to investigate whether digital images obtained by different resolutions of a digital camera are matched to the original radiographs in evaluation of caries. Methods: In this diagnostic accuracy in v...
متن کاملSpectral Estimation of Printed Colors Using a Scanner, Conventional Color Filters and applying backpropagation Neural Network
Reconstruction the spectral data of color samples using conventional color devices such as a digital camera or scanner is always of interest. Nowadays, multispectral imaging has introduced a feasible method to estimate the spectral reflectance of the images utilizing more than three-channel imaging. The goal of this study is to spectrally characterize a color scanner using a set of conventional...
