摘要:
In an image input apparatus provided with an image pick-up unit, an image signal generated by the image pick-up unit is converted into digital information. The digital information is then encrypted by using an encryption key. The encryption key is input into the image input apparatus from an external apparatus, such as an IC card. The image input apparatus erases the encryption key after the digital information has been encrypted. With this arrangement, unauthorized users can be prevented from obtaining the encryption key, and different encryption keys can be assigned to a plurality of users. Thus, the privacy and the security of the image information can be enhanced, and the copyright of the image information can be protected more reliably.
摘要:
An image communication apparatus converts image data received through a communication line into bit image data to be reproduced as a visible image by means of using a data converting unit and a reproducing unit. The apparatus converts data from a data processing apparatus into bit image data to be reproduced as a visible image by means of using the data converting unit and the reproducing unit, so as to accomplish an efficient system as a whole.
摘要:
A data communication apparatus having a connection unit for connecting an information processing terminal, a memory for storing predetermined registration data, a detector for detecting a change in the registration data stored in the memory, and a transfer unit for, if the detector detects a change in the registration data, transferring the changed registration data to change registration data in the information processing terminal connected by the connection unit.
