Abstract: An image processing method includes the following steps. A plurality of facial landmarks of a face frame are analyzed. A feature width is calculated according to the facial landmarks, and a head pose is analyzed according to the facial landmarks. The head pose is utilized to update the feature width to generate an updated width. A scale ratio of the updated width to an initial width is calculated. An object distance of a virtual camera is controlled according to the scale ratio. A two-dimensional image is captured from a virtual scene according to the object distance of the virtual camera.

Abstract: A card reader includes a card interface, and one of the pins of the card interface is selected to decide the state of the card interface. The card reader further includes a control circuit to detect the logic state of the selected pin. If the logic state is a first one, the control circuit decides the card interface is enabled; otherwise, if the logic state is a second one, the control circuit decides the card interface is disabled. In some embodiments, a switch is connected between the selected pin and a power supply or a ground terminal, to be switched by a control signal to enable or disable the card interface.

Abstract: A flash memory system is disclosed. The flash memory system includes a host and a flash memory card. The data transmission between the host and the flash memory card can be achieved with a clock signal for synchronization. The data is transmitted between the host and the flash memory card both at the falling edges and the rising edges of the clock signal.

Abstract: The present invention provides a data security device and a data security method of storage media. The data security device comprises an interface decoder for receiving control instructions and data from a host computer. The interface decoder is connected to an encryption/decryption unit and a password check unit. When a user wants to access the security data region in the storage medium, the password check unit will check the inputted password. If the password is correct, the encryption/decryption unit is activated to encrypt the data to be secured into a ciphertext and decrypt the ciphertext into a plaintext. A storage data access control unit connected to the encryption/decryption unit and the storage medium is also provided to store the ciphertext and plaintext from the encryption/decryption unit into the storage medium and read the data in the storage medium into the decryption/decryption unit.
