An image information processing system comprises a recording apparatus for recording an image having an arbitrary aspect ratio on a recording medium in the form of an image signal, and a reproducing apparatus for reading out the image signal from the recording medium, processing the image signal to form an image having an appropriate aspect ratio, and reproducing the image. The recording apparatus performs compression or expansion on the image having the arbitrary aspect ratio to convert the image into an image having a predetermined aspect ratio, and records the image having the predetermined aspect ratio in the form of the image signal. The recording apparatus also performs recording of compression/expansion information associated with the compression or the expansion. The reproducing apparatus reproduces an image having an aspect ratio equal to the aforesaid arbitrary aspect ratio from the image signal on the basis of the compression/expansion information. |

DETAILED DESCRIPTION It is, therefore, an object of the present invention to provide an image information processing apparatus and an image information processing system each of which makes it possible to solve the problems of the aforesaid conventional recording and reproducing apparatus, and which can record an image having an arbitrary aspect ratio as an image of different aspect ratio by means of a recording apparatus conforming to a standard television system and also which can automatically restore the different aspect ratio to an appropriate aspect ratio without an erroneous operation.
To achieve the above object, in accordance with one aspect of the present invention, there is provided an image information processing apparatus which comprises converting means for performing compression or expansion on an image having an arbitrary aspect ratio and converting the image into an image having a predetermined aspect ratio, image sensing means for generating an image signal associated with the image outputted from the converting means, identifying means for identifying a ratio of the compression or a ratio of the expansion, discrimination signal generating means for generating a discrimination signal associated with the ratio of the compression or the ratio of the expansion from an output of the identifying means, and recording means for recording the discrimination signal on a recording medium together with the image signal.
In accordance with a further aspect of the present invention, there is provided an image information processing system which comprises a recording apparatus for recording an image having an arbitrary aspect ratio on a recording medium in the form of an image signal, and a reproducing apparatus for reading out the image signal from the recording medium, processing the image signal to form an image having an appropriate aspect ratio, and reproducing the image.
The recording apparatus performs compression or expansion on the image having the arbitrary aspect ratio to convert the image into an image having a predetermined aspect ratio, and records the image having the predetermined aspect ratio in the form of the image signal
