20110310267 | IMAGE PROCESSING APPARATUS AND IMAGE PICKUP APPARATUS - The image processing apparatus includes an area dividing part that divides an input image produced by an image pickup system into plural image areas whose evaluation values are mutually different. The evaluation value is obtained by using a response function of the image pickup system.

20120249830 | IMAGE PROCESSING APPARATUS AND CONTROL METHOD THEREOF - After a plurality of differently exposed images are obtained, and tone levels of the plurality of images are adjusted, image elements corresponding to changes of objects are detected based on pixel value differences between the plurality of images. Then, the numbers of blown-out highlight and shadow-detail loss image elements in the image elements corresponding to the changes of the objects are counted for the plurality of images. Then, an image in which the total of the numbers of image elements is smallest is selected. Furthermore, image elements corresponding to the changes of the objects in the selected image are used as those corresponding to image elements corresponding to the changes of the objects in an HDR image to be generated. | 10-04-2012 |
20130120610 | IMAGE CAPTURE APPARATUS, CONTROL METHOD THEREOF, AND RECORDING MEDIUM - The number of images to be composited used to generate a dynamic range-extended image, and exposure conditions for respective images to be composited are determined. A proper exposure condition is determined for a subject corresponding to a moving object region, and one of the exposure conditions of the images to be composited is changed to the proper exposure condition. An image capture apparatus specifies a moving object region for a plurality of images to be composited, which are captured under the exposure conditions of the images to be composited including the proper exposure condition. A dynamic range-extended image is generated using pixels of the image to be composited, which is captured under the proper exposure condition, as those of the moving object region, which is specified for the plurality of images to be composited. | 05-16-2013 |
20140161357 | IMAGE PROCESSING APPARATUS WITH FUNCTION OF GEOMETRICALLY DEFORMING IMAGE, IMAGE PROCESSING METHOD THEREFOR, AND STORAGE MEDIUM - An image processing apparatus which can increase processing speed, reduce memory access load, and enhance ease of control in image processing. Coordinate computations through different geometric deformations are performed on respective pixels of an input image, thus calculating post-geometric deformation coordinates and coordinate moving vectors. Geometric deformation parameters for geometric deformations are output to a plurality of coordinate computation units connected in series. The coordinate moving vectors are collectively combined together to generate combined coordinate moving vectors, based on which coordinates of pixels in an image to be output are converted into coordinates of the pixels of the input image. The coordinate computations are performed based on the coordinates of the pixels of the input image and the geometric deformation parameters. The post-geometric deformation coordinates output from the preceding coordinate computation units are input as coordinates of the pixels of the image to the second and subsequent coordinate computation units. | 06-12-2014 |

The imaging apparatus includes an imaging unit employing a rolling shutter method, and a correction unit configured to perform correction processing for reducing a rolling shutter distortion on image data captured by the imaging unit. The correction unit adjusts readout positions of other lines relative to a readout position of a reference line in the image data, and sets the reference line so as to reduce a deviation amount between the readout position of the reference line and the readout positions of the other lines. | 08-07-2014 |
20140267809 | IMAGING APPARATUS AND CONTROL METHOD THEREFOR - An imaging apparatus includes a first image shake correcting unit for correcting image shake and moves a correction lens in a direction perpendicular to the optical axis using detection information obtained by an attitude detection sensor. In a second image shake correcting unit, a translational motion detecting unit acquires information about an image captured by an imaging element from a pre-processing unit so as to detect the motion of the image in the translational direction. An in-plane rotational motion detecting unit detects the motion of the image in the rotational direction about the optical axis. A geometric deforming unit acquires detection information from the translational motion detecting unit and the in-plane rotational motion detecting unit so as to correct the image shake of the corrected image, which occurs when the image is subject to rotational correction based on the detection information obtained from the in-plane rotational motion detecting unit. | 09-18-2014 |

20150022678 | IMAGE CAPTURE APPARATUS AND CONTROL METHOD THEREFOR - An image capture apparatus has an image sensor and an optical anti-shake mechanism that reduces a shake of a captured image by driving an optical correction element in a different direction from an optical axis of an imaging optical system in accordance with a detected shake. Reference coordinates for geometric deformation processing applied to the captured image are determined based on an amount and direction of a movement of the optical correction element. The geometric deformation processing is applied to the captured image using these reference coordinates and an amount of geometric deformation based on the detected shake. Coordinates of the captured image corresponding to an intersection of the optical axis and the image sensor before the optical correction element is moved through the driving are determined as the reference coordinates. | 01-22-2015 |
20150085149 | IMAGE CAPTURE APPARATUS AND CONTROL METHOD THEREFOR - An amount of change between images is calculated based on a motion vector between images obtained by an image sensor and on shake information related to a shake in a rotational direction around at least an axis perpendicular to an optical axis of an imaging optical system. Then, based on a shake correction amount determined based on the shake information and the amount of change, an image obtained by the image sensor is geometrically deformed. The amount of change is a shake component of the image capture apparatus in a direction perpendicular to the optical axis, and is calculated after cancelling at least one of a change between images caused by the shake in the rotational direction included in the shake information and a change between images caused by an influence of a difference between exposure periods of the image sensor. | 03-26-2015 |
