  "textContent": "The present invention provides an imaging apparatus which generates, based on a captured image, a depth map of an object with a high degree of precision. A sensor drive unit (12) that shifts an image sensor (11) in an optical axis direction, along with a sensor drive control unit (13), capture images A and C which are focused on a near end side and a far end side of the object, respectively, and an image B by sweeping the image sensor (11) from the near end side to the far end side, an all-in-focus image generation unit (15) generates an all-in-focus image D from the sweep image B, a blur amount calculation unit (16) calculates an amount of blur in each of the partial regions of the images A and B through deconvolution processing in an image of a region corresponding to the all-in-focus image D, and a depth map generation unit (17) generates a distance between the imaging apparatus and the object in each of the image regions, in other words, a depth map, from an amount of blur in regions corresponding to the near end image A and the far end image C and from an optical coefficient value of the imaging apparatus including a focal length of a lens.",
