A man secretly filmed up the skirts of women in the town centre, amusement arcades and on the Promenade at Blackpool.
Paul Curran used a camcorder in a supermarket bag with a hole cut out of it to carry out his perverted movie making.
Curran, 53, of Captains Lane, Bootle, Merseyside, pleaded guilty to two offences of outraging public decency before a magistrates’ court.
He was bailed for pre-sentence reports and was warned he may be jailed by Blackpool magistrates.
Curran must not possess any photographic equipment in public or enter Lancashire except for court appearances and appointments with his lawyer as conditions of his bail.
He carried out the covert filming in the resort on July 13 and 20 last year, the court was told.
Pam Smith, prosecuting, said the prosecution would ask for a Sex Offences Prevention Order to be put on Curran after he is sentenced.
Defence lawyer, Alan Godwin, told magistrates his client had no previous convictions and would oppose being made the subject of a Sex Offences Prevention Order.
