Abstract
The present invention is directed to an image pickup method and apparatus. The image pickup apparatus may include a video signal generating device that generates video signals in a first direction and a second direction and a signal processing device that changes one of a frame rate and a compression rate of the video signals in the first and second direction. The apparatus may further include a detection device for detecting that a state of the apparatus matches a predetermined condition for changing the frame rate and/or compression rate of the video signal and a controller for controlling the signal processing device so as to change the frame rate and/or compression rate of the video signals in the first and/or the second direction on the basis of the detected condition.
