Patent ID: 7630001

Claim:
An image pick-up apparatus comprising: image shooting means for shooting a subject to generate an image signal having an image shooting frame rate; a first frame rate conversion unit for receiving the image signal from the image shooting means and converting the frame rate of the image signal having the image shooting frame rate to a first desired frame rate; a second frame rate conversion unit for receiving the image signal from the image shooting means and converting the frame rate of the image signal having the image shooting frame rate to a second desired frame rate; a signal processing unit for processing an output of said first frame rate conversion unit to generate a main line image signal having the first desired frame rate; and a monitor image processing unit for processing an output of said second frame rate conversion unit to generate a monitor image signal having the second desired frame rate, wherein the first frame rate conversion unit performs frame addition to convert the frame rate of the image signal having the image shooting frame rate to the first desired frame rate, and wherein the signal processing unit performs knee correction subsequent to the frame addition of the first frame rate conversion unit.
