Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority benefit of China application serial no. 202211273700.9, filed on Oct. 18, 2022. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification. BACKGROUND Technical Field The disclosure relates to an image capturing method; more particularly, the disclosure relates to an image capturing method using a plurality of detection devices. Description of Related Art In special image capturing applications (e.g., a large-area image capturing application), a detection system performs an image capturing operation by applying a plurality of detection devices. The detection devices are respectively connected to a control unit (e.g., a computer host), respectively. However, the existing computer host may merely connect one single detection device at a time and process image data captured by the detection device. Therefore, when a plurality of detection devices are required to capture images, an image data processing procedure performed by a processing software in the computer host is required to be changed, or a device capable of time-sharing image data processing (such as a router or a multiplexer) should be added to the computer host, so as to allow the computer host to receive a plurality of image data from the detection devices at different times. Changing the data processing procedure of the processing software or controlling the time sequence of receiving the image data from the detection devices increases the cost of the detection system. SUMMARY The disclosure provides an image capturing method which allows a detection system to support expansion of a plurality of detection devices in no need of complex control of received time sequences of image data. According to an embodiment of the disclosure, an image capturing method using a plurality of detection devices to perform an image capturing operation is provided, and the image capturing method includes following steps. A first detection device is provided. A second detection device is provided and connected to the first detection device. An image capturing operation is performed by the first detection device and the second detection device, so as to generate first image data and second image data, respectively. The second image data are transferred to the first detection device by the second detection device. In view of the above, the first detection device generates the first image data, and the second detection device generates the second image data. Besides, the second detection device transmit the second image data to the first detection device. Therefore, the first detection device may be configured to set a signal path for outputting image data to a processing unit. By applying the image capturing method, the architecture of the detection system may remain unchanged or need not be significantly modified. As such, the detection system is able to support the expansion of a plurality of detection devices, and the complexity of the received time sequences of the image data is reduced.
