1. An imaging apparatus, comprising:
- an image sensor which photoelectrically converts an optical image;
an imaging processor which obtains image data via the image sensor;
an angle detector which outputs data to obtain a roll angle of the imaging apparatus as an object and a pitch angle of the imaging apparatus as an object;
a calculator which calculates the roll angle of the imaging apparatus and the pitch angle of the imaging apparatus; and
a corrector which corrects the calculated roll angle of the imaging apparatus based on (1) the calculated pitch angle of the imaging apparatus and (2) measurements made on the imaging apparatus while the angle detector is located within the imaging apparatus, andwherein the imaging apparatus is a digital camera, and wherein the digital camera includes a front surface, a back surface, a lens barrel unit in the vicinity of the front surface, a display on the back surface, and switches for operating components of the imaging processor, andwherein the angle detector is a 2-axis acceleration sensor or a 3-axis acceleration sensor, and wherein the 2-axis acceleration sensor or the 3-axis acceleration sensor is located within the digital camera.
