Patent ID: 8436892

Claim:
An image data obtaining apparatus comprising: a mode determining unit for determining an image-capturing mode, wherein the image-capturing mode is selectable between a first image-capturing mode for capturing an image of a target subject using a filter comprising a first area for transmitting light and a second area for blocking light, and a second image-capturing mode for capturing an image of the target subject without using the filter; an image-capturing unit for capturing the image of the target subject by selectively using the filter according to the image-capturing mode determined by the mode determining unit; and an image processing unit for processing captured image data, wherein: the filter is formed of a plurality of filter pieces, ends of which are attached to the image data obtaining apparatus, and the image-capturing unit comprises a control unit controlling the plurality of filter pieces to be physically positioned in a path for receiving light that is necessary for an image-capturing operation when the image-capturing mode is determined as the first image-capturing mode and for controlling the plurality of filter pieces to be physically removed from the path when the image-capturing mode is determined as the second image-capturing mode.
