Abstract:
An image pickup apparatus generates a display image signal by implementing predetermined dynamic range expansion processing on an image signal obtained by performing underexposed image pickup, and detects an image region in which a pixel within a predetermined gradation range exists as a warning region from the image signal either prior to implementation of the predetermined dynamic range expansion processing or following implementation of the predetermined dynamic range expansion processing. The image pickup apparatus synthesizes the display image signal with a warning pattern corresponding to the warning region and displays the synthesized image as a live view image.
