An imaging apparatus is provided in which a flicker is prevented. The imaging apparatus includes an imaging part that includes an optical system to form an image of a subject and an imaging element to generate an image signal by photoelectrically converting an optical image of the subject formed by the optical system, an image processing part to perform an image processing on the image signal, a display part/operation part having at least display and setting functions, a luminance change detection part to detect change of luminance of the subject, a signal processing part to calculate flicker amounts at respective frequencies based on signal intensities with respect to luminance change information acquired by the luminance change detection part, and a control unit to cause the display part/operation part to display the flicker amounts at the respective frequencies calculated by the signal processing part.

A Periodic Table Group 13 metal nitride crystal is grown by causing a reaction of a Periodic Table Group 13 metal phase with a nitride-containing molten salt phase to proceed while removing a by-product containing a metal element except for Periodic Table Group 13 metals, from the reaction field. According to this process, a high-quality Periodic Table Group 13 metal nitride bulk crystal can be produced under low pressure or atmospheric pressure.
