Set up by British rulers in the 1920s to block US movies with anti-colonial sentiment, the board went on to cut Indian films as much for their supposedly racy content as for their political overtones.
But as the country rapidly modernises, the government must walk the tightrope of catering to a more liberal, youthful India without angering still deeply conservative strands of society.
"The rules are old. We have to write them with a modern and honest outlook. The Indian value system has changed hence censor rules must change," admitted R Singh, joint secretary of the film department in New Delhi.
The government attempted to show its more open-minded approach at the recent "Cut-Uncut" festival in the capital, which screened originally censored film clips for the first time as part of Indian cinema's centenary celebrations.
Directors such as Ramesh Sippy, who made the Hindi action blockbuster Sholay in 1975, also had the chance to vent their anger at censorship culture.
Sippy said he was forced to change his film's plotline at the insistence of the censors, who decided it was too violent.
"The board said: 'We will tell you how to end the movie', and I was forced to shoot the ending again. I realised that if I keep fighting, my film's release will not be allowed."
K Hariharan, a critically-acclaimed filmmaker from south India, said he felt like "an anxious student waiting for his performance card" whenever censors watched his film.
He thinks it is time to disband the board, which he sees as a colonial remnant that restricts freedom of expression – an idea that the government may slowly be agreeing with.
"This whole business of brutally chopping scenes or forcing the filmmakers to alter the climax will have to end," said Singh, who oversees the task of issuing certificates to all Indian movies.
A more relaxed approach is already allowing filmmakers to experiment.
Aamir Khan tested the limits in 2011 with comedy Delhi Belly, a film that outraged conservative critics for its toilet humour and dialogue strewn with profanities, which surprisingly passed the censors uncut.
Despite protests at cinemas and even a court case on charges of obscenity and insulting religion, the movie ran to full houses and became a cult hit for its reflection of young people in modern, urban India.
Censors admit that regulating content is becoming an unwieldy job in a country of 1.2 billion, which has witnessed an explosion in its television and media industry along with growing Internet access.
In the last two decades, the country went from having two just state-run channels to nearly 400 private ones, and filmmakers are increasingly keen to get their work on the small screen to generate more revenue.
But as censor board chief Pankaja Thakur points out, they run a greater risk of being chopped on television.
In April last year The Dirty Picture, a popular film about the life of a 1980s Indian soft-porn star, was stopped hours before its television premiere after two court petitions objected to its content.
It took 60 cuts before it was allowed on to the screen.
"Television is a much more mass medium than the movie halls, so we have to ensure that content on TV is suitable," Thakur said.
The censors' dilemma reflects a larger debate about freedom of expression in India, which is proud of its status as the world's largest democracy but can also be quick to enact bans for fear of provoking agitation.
In 2011, northern states banned Aarakshan, which tackled the thorny issue of caste quotas in government jobs and education, because they said it "could incite civil disorder and violence".
Southern Tamil Nadu state in January forced spy thriller Vishwaroopam out of cinemas after Muslim groups complained that they were portrayed negatively, until the director finally agreed to make alterations.
Objections to sex or nudity have mainly come from conservative Hindu groups who see themselves as champions of traditional Indian values – and censors too still see their role partly as one of "moral guardianship".
They recently decided to take a more stringent approach to the "item number" – a sexually-charged song-and-dance sequence that has come under growing fire as India debates its treatment of women after a spate of shocking sex crimes.
Others say it is up to the filmmakers and audiences to bring about a change.
"Ours is a really difficult job," said Thakur.
"We want to have a liberal approach and respect artistic endeavour, but at the same time we have to address the smallest possible objection."

@amir jafri: Please find out which country is the leader in google search for porn. And no it is not a liberal secular country.
shouldn't we burn this type of films?
This will definitely help in reducing the ongoing violence and rape incidents against women in India.
Liberaloon and secularoon heaven
@muslim: No. The rating system would stilll stay. The movie rating can be adult and with that rating there should be no reason to cut scenes. The top stars don't act in porn movies because it undermines their credibility for serious roles. People especially adolescent boys who watch porn can do so easily today. Most of them outgrow porn once they mature. This happens not just in our kafir India but in the Pakistan as well. The number one search for porn on ghe web occurs from Pakistan.
Apart from ensuring that kids don't watch adult content, censor board should have no role.
so now what????porn i guess???salman khan, sharukh khan etc will b making some serious bed scenes???hmm well i didnt knew that taking out clothes means modernity.....if this is modernity than i guess the ancient cave people were the most modern people in the world.....
