Data processing method and device

The embodiment of the application discloses a data processing method. The method includes the steps of performing background correction on acquired original data according to corresponding backgrounddata; and dynamically determining the figure of decimal places in which the correction data are retained according to the size of the correction data, for example, when the size of the correction datameets a preset condition, the figure of the retained decimal places can be determined according to the preset condition. When the value of correction data is low, the data carried in the retained decimal places can increase the resolution of the correction data with small value, so that the quality of a reconstructed image is improved. The application further discloses a data processing device. 本申请实施例公开了种数据处理方法，该方法包括对采集的原始数据根据对应的背景数据进行背景校正，得到校正数据后，可以根据该校正数据的大小动态地确定该校正数据保留小数位的位数，例如当该校正数据的大小满足预设条件时，所保留的小数位的位数可以根据该预设条件确定。在校正数据的数值较低的情况下，保留的小数位中所携带的数据可以增加数值较小的校正数据的分辨率，从而提高了重建图像的质量。本申请还公开了种数据处理装置。
