Patent Images

1. An image processor that includes at least one computer processor for executing devices of the image processor, comprising:

  • a retrieval device that retrieves a data file from a network, the data file including data for generating a plurality of partial images and generating a display image by combining the plurality of partial images, the display image to be displayed in a browser running on the image processor;

    an authentication device that authenticates the data file;

    a local resource;

    a resource access control device that controls the local resource;

    a resource access supervision device for receiving authentication results and status information from the authentication device and deciding whether to allow access to the local resource; and

    a display image generating device that makes an access request to the resource access supervision device for access to the local resource, generating the display image according to a response to the access request from the resource access supervision device;

    whereinwhile the authentication device is authenticating the data file, the resource access supervision device disallows the access request and sends the display image generating device an authentication-in-progress notification; and

    when the display image generating device receives the authentication-in-progress notification, the display image generating device distinguishes between one or more first partial images requiring access to the local resource and one or more second partial images not requiring access to the local resource by analyzing the data file, generates a notification image indicating that the authentication is being performed, generates the one or more second partial images, generates the display image by combining the one or more second partial images and the notification image, and displays the display image in the browser, wherein the notification image includes a notification message to a user that the authentication process is in progress prior to completing the authentication of the data file.
