Description	Compression of astronomical images is still current task. In most applications, lossless approaches are used that do no damage to the compressed data. These algorithms, however, have lower compression ratios and are not as effective. It is therefore important to deal with more efficient lossy compression techniques. For them it is necessary to define quality criteria and level of acceptable distortion of image data. The usual multimedia approach is not possible to use for the scientific image data. They are optimized for human vision. This work deals with the influence of noise generated in the CCD structure to the defined quality criteria. It will also be shown the impact of the lossy standard JPEG2000 on quality of image data in astronomy. Compression of astronomical images is still current task.
