Results of UBVR surface photometry of the two late-type galaxies NGC 523 and NGC 7678 are presented. The observations were made at the 1-m telescope at the Maidanak Observatory (Uzbekistan) using an electronic image converter. Regions of star formation in the galaxies are identified and studied. The composition of the stellar population in the star-forming regions is estimated using (U-B)0-(B-V)0 two-color diagrams. The mechanisms stimulating star formation in NGC 523 and NGC 7678 are discussed.
