ABSTRACT:
TECHNICAL FIELD
This invention pertains to an exposure apparatus, electronic camera, data terminal, and portable communication apparatus (such as a portable telephone or PDA (Personal Digital Assistant). More particularly, this invention pertains to technology that exposes an image displayed on a liquid crystal display onto photosensitive material such as instant film.
BACKGROUND ART
In recent years, various types of electronic cameras (digital cameras) have been offered that convert object images formed by an optical lens to electrical signals and record these on a recording medium as image data. Compared to current silver salt cameras that record object images on photosensitive film, this type of electronic camera has advantages such as captured image data can be used as is on a computer, or images can be processed easily by various types of data processing.
In addition, electronic notebooks that manage individual data such as schedules or addresses and various types of portable data terminals (such as so-called mobile terminals) that can exchange data with personal computers are offered, and even this type of data terminal frequently will be able to handle image data as memory capacity is expanded or CPU speed is increased.
Although these portable electronic devices can be viewed even outdoors or in outdoor venues by displaying various data on a display, generally, it is not possible to output data on the displayed screen to a printer on the spot.
For example, in the case of an electronic camera, a recorded image can be confirmed by a liquid crystal viewfinder, but to obtain a printed image (photograph or print image) requires an operation in which image data are taken up by a personal computer and outputted to a printer to print, and a photograph (print image) cannot be obtained on the spot where it was photographed.
In addition, dedicated printers (photoprinters or sublimation printers) are offered that can output prints by taking up data directly by the external memory medium of the camera without passing through a personal computer. However, because these printers use a great amount of electricity and are structurally difficult to miniaturize, at present, no printer is yet offered that can be made portable.
If product size is ignored, it is certainly considered technically feasible to add a printing function even to existing electronic cameras or data terminals. However, as can be seen in the severe recent competition to miniaturize digital video cameras and competition to make notebook personal computers thinner, it cannot be denied that especially for these electronic cameras that have portability as a premise, the weight, size, and thickness of the product are major factors governing demand for this product.
DISCLOSURE OF INVENTION
Therefore, the purpose of this invention is to enable print output of display data without losing portability in various types of portable electronic devices such as electronic cameras or data terminals that can display various data on a display.
To achieve the purpose given above and solve the problems described above, the exposure apparatus with which a first aspect of this invention is concerned is an exposure apparatus that can copy display data on a liquid crystal display means onto photosensitive material, and it has a photosensitive material holding means that holds photosensitive material on the back of a liquid crystal display means, a first shutter means that can let through and block light from the above-mentioned liquid crystal display means to the above-mentioned photosensitive material, and a second shutter means that blocks infiltration of external light by covering the display surface of the above-mentioned liquid crystal display means during exposure of the above-mentioned photosensitive material.
The electronic camera with which a second aspect of this invention is concerned is an electronic camera that has a photographing means that converts an object image formed by a photographic lens to image data and a liquid crystal display means that can display the object image based on said image data, and can copy the above-mentioned object image onto photosensitive material, and it has a photosensitive material holding means that holds photosensitive material on the back of a liquid crystal display means, a first shutter means that can let through and block light from the above-mentioned liquid crystal display means to the above-mentioned photosensitive material, and a second shutter means that blocks infiltration of external light by covering the display surface of the above-mentioned liquid crystal display means during exposure of the above-mentioned photosensitive material.
The data terminal with which a third aspect of this invention is concerned is a data terminal that can copy display data on a liquid crystal display means onto photosensitive material, and it has a photosensitive material holding means that holds photosensitive material on the back of a liquid crystal display means, a first shutter means that can let through and block light from the above-mentioned liquid crystal display means to the above-mentioned photosensitive material, and a second shutter means that blocks infiltration of external light by covering the display surface of the above-mentioned liquid crystal display means during exposure of the above-mentioned photosensitive material.
The portable communication apparatus with which a fourth aspect of this invention is concerned is a portable communication apparatus that has a liquid crystal display means and a communication means that can receive at least data that can be displayed on said liquid crystal display means, and it has a photosensitive material holding means that holds photosensitive material on the back of a liquid crystal display means, a first shutter means that can let through and block light from the above-mentioned liquid crystal display means to the above-mentioned photosensitive material, and a second shutter means that blocks infiltration of external light by covering the display surface of the above-mentioned liquid crystal display means during exposure of the above-mentioned photosensitive material.
In a fifth aspect of this invention, such a portable communication apparatus further has a photographing means that can convert an object image formed by a photographic lens to image data, the above-mentioned communication means can transmit the above-mentioned image data, and the above-mentioned liquid crystal display means can display an image based on the above-mentioned image data.
The exposure apparatus with which a sixth aspect of this invention is concerned furthermore is an exposure apparatus that can copy display data on a liquid crystal display means onto photosensitive material, it has a display window in which the above-mentioned liquid crystal display means can be placed, a photosensitive material holding means that holds photosensitive material within the housing of said apparatus, and a display window shielding means that can block infiltration of external light by shielding the above-mentioned display window, and the above-mentioned liquid crystal display means is supported within the above-mentioned housing such that it rotates freely between a display position in which its display surface faces the above-mentioned display window and an exposure position in which its display surface faces the above-mentioned photosensitive material.
The electronic camera with which a seventh aspect of this invention is concerned also is an electronic camera that has a photographing means that converts an object image formed by a photographic lens to image data and a liquid crystal display means that can display the object image based on said image data, and can copy the above-mentioned object image onto photosensitive material, it has a display window in which the above-mentioned liquid crystal display means can be placed, a photosensitive material holding means that holds photosensitive material within the housing of said apparatus, and a display window shielding means that can block
