DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to an electronic camera. In particular, it relates to an electronic printing camera in which an optical image of an object is obtained through an optical lens and converted into an electrical signal to be output for printing by a thermal printer.
BACKGROUND ART
Conventionally, an electronic camera of this kind has been proposed in that an optical image obtained through an optical lens from an object to be picked up is converted into an electrical signal, after which an editing process such as an enlargement, contraction of the resultant image is suitably carried out, followed by reproduction of the image on a display by an electronic view finder and printing of the image by a printer (Japanese Patent Application Laid Open No. 189785 in 1986).
As prior arts, polaroid cameras and the like are well known as means for instantaneously printing the object image obtained through the optical lens. However upon printing with such a camera, the use of thermosensible papers (thermal papers) with a special photosensitive material provides the increase of a printing cost. It is difficult for the camera to store and reprint the image. Further, it is impossible to perform the editing processes such as enlargement, contraction, and trimming of the images.
With the foregoing background, proposed was an electric camera which is so constructed that the optical image is converted into the electrical signal, after which the editing process such as enlargement, contraction is suitably carried out followed by reproduction of the resultant image by the electronic view finder and printing the image by the printer.
The above conventional electronic camera may convert the optical image of the object into the electric signal, which must however be reproduced on the display as the image, the contents of which are thereafter printed by the printer. Accordingly, the electronic view finder for reproducing the image on the display and a control circuit for controlling the above finder or display are required. This, however, necessitates the same procedure as in the conventional photography thereby resulting in the increased cost for the electronic camera and a longer time for taking a photograph.
DISCLOSURE OF THE INVENTION
An object of the invention is to provide an electronic camera wherein an optical image of an object obtained through an image pick-up lens is converted into an electrical signal, which is temporarily stored as digital image data and simultaneously printed out as a predetermined simple monitor-image, followed by ascertaining the picked-up image, after which the image data stored is subjected to processes such as the enlargement, contraction, trimming, or conversion between positive and negative, so that the images may repeatedly be printed in various forms upon any requirements thereby preventing a confirmation of the image contents by use of such an electronic view finder in the prior art and permitting the simplified and rapid multilateral printing performance of the image to be realized with a lower cost.
An electronic printing camera according to the invention in which an optical image of an object obtained through an image pick-up lens is converted into an electric signal by a solid-state image pick-up element sensor and further converted into an image signal by an analog processing circuit, the image signal obtained is converted into digital image data by an A/D converter followed by storing in a RAM, thereafter the digital image data is outputted to a printer for printing performance, is characterized in that the electronic printing camera is provided with a storage means being set therein with various kinds of image processing programs which process the digital image data stored in the RAM in various ways and respectively output to the printer, a plurality of pushbutton switches for selecting the image processing programs set in the storage means, and a control means for controllably driving the printer by outputting to the printer the digital image data stored in th
