With the digitalization of digital technology, the digitalization of the camera device field is accelerating. Unlike high-end cameras for professionals, automatic cameras have become widespread due to their ease of use and low cost, and the advancement of automatic cameras has also made great strides as digital technology has been widely applied to automatic cameras. In particular, as digital imaging technology is applied to automatic cameras these days, digital still cameras are no longer needed.

Early digital still cameras were not widely available due to their high price and difficulty in use, but the development of storage media such as flash memory and the increasing number of developers have made them easy to use and inexpensive. In spite of the development of the company and the increase of the number of participating companies, the camera using the existing physical film has maintained its market size due to the convenience of use and the advantage that the user can see it by printing on the actual photo paper.

Digital still cameras, unlike conventional automatic cameras, are difficult to print on real photo papers and have a storage difficulty in storing data about photos on a personal computer. It is difficult to spread because it is difficult.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above and to achieve smooth digital still picture data transmission between various devices that handle digital still pictures. After transferring digital still image data from a device, a digital still image capturing device, a digital data storage device, a wired / wireless data communication device, or a digital still image editing device to a storage medium mounted in the device, the user carries the device with The present invention provides a portable color compressed still picture display device provided with mobility capable of viewing a digital still picture through an image display device having the same size as an actual photo paper mounted on the device regardless of time and place.
