Personal image analyzing system (PIAS) is used to analyze deep CCD images of galaxies in the general sky-background observed by Tyson and Seitzer (1988, Astrophys. J., 335, 553). Peculiar shaped galaxies on 4 brightness threshold in PIAS images are classified into several types and statistics are taken for finding differences between the Tyson-Seitzer general sky-background fields and an artificial field that is artificially made by comprehensive way from a map of rich cluster of galaxies to simulate Tyson-Seitzer field of galaxies. One or two types of peculiarity are found to be relatively rich in the Tyson-Seitzer than in the artificial as compared to other characteristic types. For the type of peculiarity which could involve the case of gravitational lensing, no statistical differences can be found between the Tyson-Seitzer and the artificial.
