An imaging apparatus includes: an imager to capture a subject image to generate an image signal; an image processor to perform predetermined processing on the image signal to generate image data; a display to display luminance level information showing a luminance level in the image; an operation receiver to input a user operation; and a controller to control the display and the operation receiver. The image processor generates the image data using a predetermined gamma curve in which a light amount in the image signal is associated with a luminance level to compress as the light amount increases. When the operation receiver receives a user operation for setting a luminance level in the luminance level information, the controller controls the display to represent the luminance level by a stop number indicating a scaling rate of a corresponding light amount in the gamma curve.
