Portable camera link data acquisition system and portable camera link data acquisition method

In order to solve the technical problems that in the prior art, a camera link data collecting device is inconvenient to carry and high in cost; or although the device is convenient to carry, the single tap data bit of the camera link cannot be acquired by more than 8 bits but not 16 bits; or a plurality of tap non-8bit integer multiples and less than 24bit data of the camera link cannot be acquired, the invention provides a portable camera link data acquisition system and a portable camera link data acquisition method. According to the invention, the FIFO is used for caching the acquired camera link data; the length of the read enable signal is limited; if the bit width of the data read from the FIFO is less than 16 bits, high-order zero padding is changed into 16-bit output; and if the bit width of the data read from the FIFO is 8 bits or 16 bits, the data are directly output and are finally displayed through an external computer. 为解决现有技术中cameralink采集数据装置不便于携带、成本高，或者虽然便于携带但无法实现对cameralink单个tap数据位数超过8bit而非16b
