An imaging apparatus includes: a captured image data generation unit generating captured image data by capturing a subject; a positional information acquisition unit acquiring positional information indicating a position at which the captured image data are generated; an area determination unit determining whether the position indicated by the acquired positional information is included in a positional information conversion area for converting the acquired positional information; a positional information conversion unit, when the area determination unit determines that the position indicated by the acquired positional information is included in the positional information conversion area, converting the acquired positional information into positional information indicating a position different from the position indicated by the acquired positional information; and a record control unit, when recording the generated captured image data, carrying out control to record the generated captured image data in association with the positional information converted by the positional information conversion unit.

Information recording apparatus, imaging apparatus, information recording method, and program

A detecting unit generates defference data between optical black level of digital input data and a predetermined black level and generates .gamma. characteristics selection signal. An offset signal obtained from the difference is added to the input data by an adding circuit. A .gamma. characteristics setting unit is supplied with the difference data and the output signal of the adding circuit and outputs a signal in which a white level, black level and .gamma. characteristics are corrected.
