摘要： A system and process for improving the appearance of improperly colored and/or improperly exposed images is presented. This involves the use of two novel techniques—namely an automatic color correction technique and an automatic exposure correction technique. The automatic color correction technique takes information from within an image to determine true color characteristics, and improves the color in improperly colored pixels. The automatic exposure correction technique measures the average intensity of all of the pixels and adjusts the entire image pixel by pixel to compensate for over or under exposure. These techniques are stand alone in that each can be applied to an image exclusive of the other, or they can both be applied in any order desired.

摘要： A method and system of controlling access to a hardware or software feature provided by a host is disclosed. An application seeking authorization to access a feature transmits a credential and an index to a host agent within the host. The index is associated with the requested feature. The host agent reads credential validation data from a storage location corresponding to the index in a non-volatile storage device in communication with the host. The validity of the credential is determined based on the credential validation data, and an authorization is transmitted if the credential is valid. A third party can control the outcome of the validity determination by sending an instruction to the host to replace the credential validation data with invalid data that causes the validity test to fail. The third party can also control the non-volatile storage device data used by the application to calculate the credential.

摘要： A first storage unit is bound to a second storage unit based on a binding type associated with content on the first storage unit, the first storage unit being operated through a first host device, and the second storage unit being operated through a second host device. When content on the first storage unit is requested in the first host device, the first host device will calculate an account identifier based on the binding type associated with the requested content and send the account identifier to a server. The server will send the account identifier to the second host device, and the second storage unit will use the account identifier to calculate a credential. The credential will be sent to the first host device through the server. The credential can be used to access the requested content if the credential is valid.

摘要： Technology for replacing a first storage unit operatively coupled to a device is provided. Content of the first storage unit is sent to a new storage unit that serves as the replacement of the first storage unit. In one embodiment, the content is first sent to a trusted third-party server and then transferred from the server to the new storage unit. A portion of the content on the new storage unit is adjusted in one embodiment to maintain content security features that were implemented in the first storage unit. The upgrading can be performed under the control of a software entity that is installed on the device. In various embodiments, the first storage unit may be bound to a third storage unit prior to the upgrade process. In such cases, the process can include measures to bind the new storage unit to the third storage unit.

摘要： A non-volatile memory interface device contains first, second, and third communication interfaces configured for first, second, and third protocols, respectively. The device also contains a memory controller that selectively communicates between the first and second communication interfaces, and between the first and third communication interfaces. The device also contains a receptacle that can receive a removable non-volatile memory card and electrically connect the card to the second and third communication interfaces. The first communication interface may be a Universal Serial Bus Interface and may be in communicatively coupled to a USB connector. The second communication interface may be an ISO 7816 interface. A communications adapter is an enclosure containing a receptacle that can receive a non-volatile memory card and a USB connector. The USB connector is communicatively coupled with the non-volatile memory card in the receptacle. The receptacle's second communication interface with the non-volatile memory card is disabled.
