First Claim
Patent Images

1. image display with image cache memory comprises:

  • Image-display units is carried out the process that the view data that provides is provided;

    Image buffer storage identifier generation unit obtains the cryptographic hash of regular length from the sampled data of raw image data, and generates image buffer storage identifier unique concerning described raw image data according to the cryptographic hash of regular length;

    The image buffer storage search unit, when described image buffer storage identifier generation unit generates the image buffer storage identifier, whether the image buffer storage data that the image buffer storage identifier has been added in inspection are stored in the described image cache memory, and when storing the image buffer storage data, data cached from described image cache memory reading images, and provide the image buffer storage that is read data for described image-display units;

    AndThe image buffer storage generation unit, when described image buffer storage search unit judges that the image buffer storage data are not stored in the described image cache memory, for described image-display units provides raw image data, and add to generate the image buffer storage data in the raw image data to by the image buffer storage identifier that will be generated by described image buffer storage identifier generation unit, and with the image buffer storage data storage in described image cache memory.
