Such evolution of mobile phones to all-inone products which contain various functions in one device was promoted by demand of consumers. Such development of mobile phones were accomplished in the last few years. Especially, Korean companies were the leading companies in such rapid changes of mobile phones. Also, the development of built-in cameras on the advanced mobile phones has reduced the size of compact camera market which once prospered. These built-in cameras focus on satisfying minimum consumers' demand (in other words, taking pictures only suitable to post on the web). According to such changes in circumstance, bulit-in cameras are more and more developing and it creates the situation that consumers does not want to purchase digital cameras. In this study, performance of built-in cameras of 4 different mobile phone manufacturers was investigated, which were the most popular brands between June and August, 2008. In addition, to compare performance of mobile phone built-in cameras which were presented in this study, the results of photographing GretagMacbeth color chart, Gray scale and ISO Resolution chart taken by built-in cameras from 4 different brands were compared and analyzed using Imatest.
