  • Patent number: 8271690
    Abstract: In a device having a capability of using time data acquired from an external time information generator, a notification unit notifies a user of time information. The notification unit also notifies the user whether the notified time information is based on time data acquired from the external time information generator. Processing performed by the device is restricted depending on a status associated with time information. Although some types of processing are allowed when the device is in a status in which the time information is based on the time data acquired from the external time information generator, the same type of processing are disabled when the device is in any other status associated with time information.

  • Patent number: 6438574
    Abstract: In a multifunctional apparatus used by a plurality of users, image data entered in a variety of formats from various information sources such as a scanner, computer, facsimile machine and electronic mail is stored on a memory medium such as a hard disk in correspondence with user IDs. By operating the multifunctional apparatus storing this image data to enter a user ID, a list of image data stored in correspondence with the user ID is displayed together with information relating to the image data. Desired image data is selected from the list and is subjected to processing such as printing or deletion. Image data for which a password has been set can be processed by entering the correct password. By virtue of the processing described, handling of the entered image data is facilitated and protection of confidentiality is made possible.

  • Patent number: 5555093
    Abstract: Input image data and a generated background image pattern are input into a selection circuit. A determination circuit determines whether the image data exceeds a predetermined threshold value, and outputs a determination signal to the selection circuit. If the determination signal indicates that the image data exceeds the threshold value, the selection circuit selects the input image data. If the determination signal indicates that the image data does not exceed the threshold value, the selection circuit selects the background image pattern, thereby replacing areas of the image data which do not exceed the threshold value with the background image pattern.
