Abstract: A method for controlling a camera is provided. An image transmitted from a camera is received and detection is performed on the image, where if a target object is not detected, a search instruction for controlling the camera to rotate in a vertical direction is transmitted to the camera until the target object is detected in an image. Then posture parameters of the target object in the image are acquired, where if the posture parameters do not match a preset posture parameter criteria, a fine adjustment instruction for controlling the camera to rotate and move is transmitted to the camera, until the posture parameters of the target object match the preset posture parameter criteria. A device for controlling a camera and a financial device terminal are further provided.

Abstract: A flattening device includes: a holder configured to support the following components; at least one flattening roller set, including a first flattening roller and a second flattening roller arranged oppositely at two sides of a sheet medium conveying path; and a power mechanism configured to drive the first and second flattening rollers to rotate. A surface of the first flattening roller is distributed with n arc-shaped grooves arranged in parallel with an axis direction of the first flattening roller, wherein n is a natural number greater than or equal to 1; and a surface of the second flattening roller is provided with at least one arc-shaped protruding portion in rolling engagement with the arc-shaped grooves of the first flattening roller; and wherein, the first flattening roller and the second flattening roller are in rolling engagement to form a conveying passage for the sheet medium.

Abstract: A Linux system-based CEN/XFS standard architecture and a Linux system-based CEN/XFS standard implementation method are provided, for addressing the technical problem that implementation of a CEN/XFS standard on the Linux system is absent in the prior art. The Linux system-based CEN/XFS standard architecture is applicable to a financial self-service device adopting the CEN/XFS standard. The system of the financial self-service device includes: an application program layer, an XFC management layer, an SP layer and a device driver layer. In the architecture, the XFC management layer is divided into: a dedicated application layer, a universal application layer and a system service layer.
