Patents by Inventor Hirotake Usami

Hirotake Usami has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11930272
    Abstract: The invention performs a processing for improving an image quality of a camera in a state where a sufficient link rate cannot be ensured. A controlling method for a camera includes an imaging sensor configured to acquire an imaging data, a signal processing unit configured to perform an image processing on the imaging data, a buffer into which data subjected to the image processing is written, and a format conversion unit configured to convert a format of data read from the buffer and transmit the data to a transmission path, wherein the controlling method includes a status prediction step of predicting a status of the buffer based on a readout rate of the imaging sensor and a link rate of the transmission path and generating a status prediction information, and an adjustment step of adjusting a content of the image processing according to the status prediction information.

  • Patent number: 7636439
    Abstract: Data to be encrypted is effectively encrypted by a data delivery system for encrypting the data to be encrypted with a transmitting apparatus and decrypting a cipher thereof with a receiving apparatus. In a configuration for encrypting and decrypting the data to be encrypted by using a random number sequence generated by a random number generating portion for generating the random number sequence uniquely decided from an input parameter, the transmitting apparatus generates the input parameter to perform encryption based on metadata of the data to be encrypted while the receiving apparatus generates the input parameter to perform cipher decryption based on the metadata embedded in the data to be encrypted.
