Provided are an image sensor module, an image processing device, and an image compression method. The image compression method includes receiving pixel values of a target pixel group to be compressed in the image data and reference values of reference pixels to be used for compression of the target pixel group, generating a virtual reference map by applying an offset value to each of the reference values, compressing the pixel values of the target pixel group based on the virtual reference map, and generating a bitstream based on a compression result and compression information based on the virtual reference map. 提供了一种图像传感器模块、图像处理装置和图像压缩方法。图像压缩方法包括：接收图像数据中待压缩的目标像素组的像素值和要用于压缩目标像素组的参考像素的参考值；通过将偏移值应用到参考值中的每一个来生成虚拟参考映射；基于虚拟参考映射来压缩目标像素组的像素值；以及基于虚拟参考映射生成包括压缩结果和压缩信息的比特流。
