PURPOSE:To realize a miniature electronic camera belonging to the optical apparatus by detecting the picture and then converting it into the electric signal through the photoelectric converting element, recording the electric signal onto the cylindrical recording medium and then turning this recording medium by the driving medium. CONSTITUTION:In place of the film of the ordinary camera, two-dimensional image sensor 2 plus disk-type or cylindrical magnetic sheet 3 is provided. And picture 5 image-formed on sensor 2 through lens 4 is applied to magnetic recording head 6, and the electric signals equivalent to one frame of the TV are recorded on sheet 3 which is turned in a high speed by head 6. This recorded sheet 3 is added to the TV picture receiver incorporating the general magnetic sheet reproducer to reproduce the still picture. In addition to the optical system including lens 4, the following component units are added to the electronic camera of such constitution: two- dimensional image sensor 2; scanning circuit 13; amplifier circuit 14; magnetic head 6; magnetic sheet turning motor 15; and rotational speed control circuit 16 each. Thus a miniature camera which incorporates the electronic device and is suited for carrying purpose can be obtained. |
