Abstract:
1. An image pick-up and audio signal processing apparatus comprising: an image pick-up unit; a driving unit that drives an optical unit to change a size of an image to be obtained by the image pick-up unit; a changing unit that performs a process for changing a size of an image which is obtained from the image pick-up unit; a central processing unit (CPU) that (a) controls the changing unit to change a size of an image which is obtained from the image pick-up unit without driving the optical unit until a first period elapses since an instruction for starting changing a size of an image is input, (b) controls the driving unit to change a size of an image to be obtained by the image pick-up unit until a second period elapses since the first period elapses, and (c) controls the changing unit to change a size of an image which is obtained from the image pick-up unit without driving the optical unit until a third period elapses since the second period elapses; an audio obtain unit that (d) obtains first audio data until the first period elapses since the instruction is input, (e) obtains second audio data until the second period elapses since the first period elapses, and (f) obtains third audio data until the third period elapses since the second period elapses; and an audio processing unit that performs a process for reducing a noise included in the second audio data by using at least one of the first audio data and the third audio data, wherein, until an instruction for finishing changing a size of an image is input, the CPU controls at least one of the changing unit and the driving unit so that a size of an image to be changed by the changing unit and the optical unit becomes constant.
