Abstract: A Serial Peripheral Interface (SPI) master (110) and method therein for transferring data to a peripheral device in a data communication and processing system (100) are disclosed. The SPI master (110) comprises a memory (111) comprising a list of packets, each packet comprises data associated with a time parameter indicating at which time the data is to be transferred to the peripheral device. The time parameter is configurable. The SPI master further comprises a serial transmit and receive unit (112) to transfer the data in the list at a time according to the time parameter associated with the data.

Abstract: There is provided a method, a system and a device for displaying an image corresponding to a first field of view to an operator of an image capturing device. The method comprises receiving input data relating to a change in at least one of a position, an orientation, or a scaling of the first field of view and determining, based on the input data, at least one of a position, an orientation or a scaling of the first field of view with respect to a second field of view which is larger than the first field of view. Further, the method comprises receiving an image captured by the image capturing device and determining an overlapping portion of the first field of view and the received image. An image to be displayed is then determined by using image data of the received image in the overlapping portion, and using image data of the second field of view in the non-overlapping portion. The invention is advantageous in that it provides an improved operation of the image capturing device.

Abstract translation: 提供了一种用于向摄像装置的操作者显示与第一视场相对应的图像的方法，系统和装置。 该方法包括接收与第一视野的位置，取向或缩放中的至少一个相关的改变的输入数据，并且基于输入数据确定位置，方向或方向 相对于大于第一视野的第二视场的第一视场的缩放。 此外，该方法包括接收由图像捕获装置拍摄的图像，并确定第一视场和接收图像的重叠部分。 然后，通过使用重叠部分中的接收图像的图像数据，并使用非重叠部分中的第二视场的图像数据来确定要显示的图像。 本发明的优点在于其提供了图像捕获装置的改进的操作。
