A search of Booth's vehicle located the laptop and a standard camera.
Further examination of the laptop identified approximately 605 still images, the majority of which were of teenage girls walking along streets in Napier and other public places.
Approximately 100 of the images were up the skirts of the three unidentified women.
Booth had previously pleaded guilty.
His lawyer, Jonathan Krebs, said his client was remorseful and ashamed of his actions.
He said his client acknowledged he clearly needs help.
Mr Krebs told the court long-time cannabis use had lowered Booth's inhibitions and enabled him to carry out the offending.
He said Booth had now been drug free for half a year.
Judge Rea said he could not see a "clear connection between cannabis use and your desire to go and carry out this sort of offending".
He sentenced Booth to four months home detention and made an order for the destruction of the objectionable images.
It is the second case of its kind in a matter of weeks, with Richard Snook, 42, being sentenced to home detention for similar crimes earlier this month.
