Abstract

An imaging display apparatus includes an imaging unit that images a subject at a first frame rate and outputs an imaging signal, an image processing portion that generates an image signal based on the imaging signal, a VRAM that stores the image signal, and a display unit that performs displaying based on the image signal at a second frame rate which is equal to or greater than N (N is a natural number equal to or greater than 2) times the first frame rate. The VRAM stores the image signals for one frame to be displayed by the display unit. The display unit performs displaying N times based on the image signals for one frame.

Claims

1-2. -2. (canceled)

3. An imaging display apparatus comprising:

an imaging unit that images a subject at a first frame rate and outputs an imaging signal;

an image processing portion that generates an image signal based on the imaging signal; and

a display unit that performs displaying based on the image signal at a second frame rate which is equal to or greater than N (N is a natural number equal to or greater than

     2) times the first frame rate,

wherein the display unit starts to perform displaying N times based on the image signal after image signals for predetermined lines fewer than the image signals for one frame among the image signals are generated.

4. The imaging display apparatus according to claim 3,

wherein the image signals for predetermined lines are equivalent to (N−

1)/N.

5. The imaging display apparatus according to claim 3, further comprising:

a timing control unit that outputs a horizontal synchronizing signal and a vertical synchronizing signal to the display unit,

wherein after displaying is performed N times, in a case where the image signals for predetermined lines fewer than the image signals for one frame among the image signals for one frame to be displayed in one succeeding frame are not generated, outputting the vertical synchronizing signal is delayed until the image signals for predetermined lines are generated.

6. The imaging display apparatus according to claim 5,

wherein the timing control unit outputs a dummy horizontal synchronizing signal while outputting the vertical synchronizing signal is delayed.

7. (canceled)

8. An imaging display apparatus comprising:

an imaging unit that images a subject at a first frame rate and outputs an imaging signal;

an image processing portion that generates an image signal based on the imaging signal; and

a display unit that performs displaying based on the image signal at a second frame rate which is equal to or greater than N (is a natural number equal to or greater than

     2) times the first frame rate,

wherein the second frame rate is as much greater than the frame rate which is N times the first frame rate as one to several fps.

9. A method of controlling an imaging display apparatus including an imaging unit which images a subject at a first frame rate and outputs an imaging signal, an image processing portion which generates an image signal based on the imaging signal, and a display unit which performs displaying based on the image signal at a second frame rate which is equal to or greater than N (N is a natural number equal to or greater than 2) times the first frame rate,

wherein after image signals for predetermined lines fewer than image signals for one frame among the image signals are generated, the display unit starts to perform displaying N times based on the image signal.

10. A method of controlling an imaging display apparatus including an imaging unit which images a subject at a first frame rate and outputs an imaging signal, an image processing portion which generates an image signal based on the imaging signal, and a display unit which performs displaying based on the image signal at a second frame rate which is equal to or greater than N (N is a natural number equal to or greater than 2) times the first frame rate,

wherein the second frame rate is as much greater than the frame rate which is N times the first frame rate as one to several fps.
