In today’s world of electronic revolution digital images play an important role in consumer electronics. Digital images are stored in different formats, each format having its own set of characteristics making it suitable for any specific area of application. This paper analyzes different image file formats which gives an idea about different file formats with their advantages, disadvantages and analyzes their specific areas of application. Examples analyzing certain images, their file formats and their visible properties are also included

Who are the peoples in barriers of time and distance issues, those kinds of peoples can't achieve their expectation in education. Therefore, we have developed a system for addressing to give a great chance to learn online with more facilities with the use of server configuration. The remainder of this document describes the functional requirements of the Virtual Academy in detail, including descriptions of the individual modules, integration points between existing modules and high-level scope of new modules to be developed specifically for the Virtual Academy.

A colorimetric analysis and design method for cameras is presented which enables a camera to be used as an imaging colorimeter, capable of capturing an accurate record of the Commission Internationale de l'Éclairage (CIE) coordinates of the imaged objects. The spectral response characteristics of some of the component observers in the 1964 CIE Standard Observer average are first analysed and compared. CIE colour coordinates are calculated using both the Standard Observer average and individual observer CMFs for each of 32 test colours. The personal coordinates for each observer are then linked to differences in their visual response CMFs at the spectral level. A colorimetric testing and optimization method for cameras is then reported, which allows the colour capture properties of imaging systems to be analysed, controlled and modified. The method is based on imaging spectrally defined colour charts and is used to demonstrate that even minor differences in the chosen RGB filter/sensor characteristics substantially affect the numeric accuracy of the colour-defining information in images. Colour imaging error is quantified and minimized, first by establishing the camera RGB to CIE XYZ relationship, and then by adjusting the spectral response of the sensors. Under controlled lighting and exposure conditions, the design method enables output pixel-colour definitions that are a close analogue of the measured CIE XYZ tristimulus values for the imaged surface colours.
