System for determining image size ratio of data for presentation of proper size on displays or printers from optical storage

An image information processing apparatus, comprising:

• first memory means for storing image information;
• means for retrieving the image information from the first memory means;
• second memory means for storing the image information retrieved by the retrieving means;
• means for reducing a size of the image information stored in the second memory means, in accordance with a size converting ratio, a size of the reduced image information being limited to within a predetermined range of the reducing means;
• means for outputting the image information reduced by the reducing means;
• means for determining a first size converting ratio corresponding to the size of the image information stored in the second memory means and a size of the image information outputted from the outputting means, the determining means including means for ascertaining whether or not the first size converting ratio is within the predetermined range of the reducing means and means for setting a second size converting ratio which is within the predetermined range of the reducing means, when the first size converting ratio is outside the predetermined range;
• and
• means for controlling the converting means, the controlling means including first means for supplying the size reduced image information to the outputting means when the reducing means reduces the size of the image information stored in the second memory means by the first converting ratio and second means for supplying the size reduced image information to the second memory means when the reducing means reduces the size of the image information stored in the second memory means by the second converting ratio, wherein the determining means determines the first converting ratio corresponding to the image information supplied by the second memory means and a size of the image information outputted by the outputting means.
