Imaging apparatus and imaging method

摘要

An imaging apparatus includes an imaging section, an imaging acquisition range control section, a distortion information obtaining section, and a display section. The imaging section includes a lens and obtains an image data by imaging a subject image. The imaging acquisition range control section controls an acquisition range of the image data such that a part of the subject image is read out. The distortion information obtaining section obtains distortion information of the lens. The distortion correction section corrects distortion of the image data in accordance with the distortion information. The display section performs enlarged live-view display operation to display an enlarged image of the corrected image data in the acquisition range. The imaging acquisition range control section updates the acquisition range, when the distortion information is changed while the enlarged live-view display operation is performed, in accordance with the changed distortion information.

主权项

1. An imaging apparatus comprising:
an imaging section including a lens to form a subject image, which obtains an image data by imaging the subject image formed by the lens; an imaging acquisition range control section which controls an acquisition range of the image data obtained by the imaging section, such that a part of the subject image is read out; a distortion information obtaining section which obtains distortion information of the lens; a distortion correction section which corrects distortion of the image data in the acquisition range obtained by control of the imaging acquisition range control section, in accordance with the distortion information obtained by the distortion information obtaining section; and a display section which performs enlarged live-view display operation to display an image obtained by enlarging the image data in the acquisition range, the image data in the acquisition range corrected by the distortion correction section, wherein the imaging acquisition range control section updates the acquisition range, when the distortion information of the lens is changed while the enlarged live-view display operation is performed by the display section, in accordance with the changed distortion information of the lens, wherein the distortion correction section determines the acquisition range of the image data obtained by the image section based on the distortion information, wherein the imaging acquisition range control section acquires the image data from the imaging section based on the acquisition range of the image data by capturing an image signal for each pixel of a photoelectric conversion surface without interlacing, and wherein the image acquisition range control section acquires the image data of a whole pixel range of the imaging device by capturing image signals with interlacing, when the display section performs non-enlarged live-view display operation to display an image data of the whole pixel range of the imaging device.
