Patent ID: 8063950

Claim:
An imaging apparatus, comprising: a switch that starts a video adjustment process; a video input unit that generates a video signal by converting light from a subject; a signal processing unit that processes the video signal through the video adjustment process in accordance with an input from the switch; a waveform generation unit that generates a waveform signal based on the video signal processed by the signal processing unit in accordance with the input from the switch and outputs the waveform signal for a predetermined period, wherein the waveform generation unit determines whether an adjustment result of the video adjustment process is valid based on the waveform signal, and changes an output period for which the waveform signal is output based on a result of the determination and wherein the waveform generation unit sets the output period of the waveform signal as a first period when determining that an adjustment result of white balance adjustment or black balance adjustment is valid based on the waveform signal, and sets the output period of the waveform signal as a second period longer than the first period when determining that the adjustment result of white balance adjustment or black balance adjustment is invalid; a synthesized signal generation unit that generates a synthesized signal by combining the video signal and the waveform signal; and a display unit that displays the synthesized signal.
