An information processing apparatus includes a first acquisition unit configured to acquire a first image generated based on light passing through a lens unit, a second acquisition unit configured to acquire information corresponding to a pupil distance of the lens unit when the first image is acquired, and a correction unit configured to generate a second image, which is generated by correcting optical characteristics of the lens unit based on a position of the lens unit at the time of acquisition of the first image, wherein the correction unit corrects the first image affected by the optical characteristics based on the lens position of the lens unit based on the information corresponding to the pupil distance acquired by the second acquisition unit.

Information processing apparatus, imaging apparatus, and method for correcting images

An image processing apparatus which is capable of accurately correcting for chromatic aberration of magnification in an area peripheral to a taken image using the taken image. Areas including edges in image data are extracted, and the amount of chromatic aberration of magnification is calculated as the amount of area chromatic aberration of magnification in each area with respect to each color component. Based on lens design values, chromatic aberration of magnification in each area is calculated as the amount of lens chromatic aberration of magnification. By using the amount of area chromatic aberration of magnification and the amount of lens chromatic aberration of magnification in adjacent areas next to an indefinite area matching predetermined conditions, the amount of lens chromatic aberration of magnification relating to the indefinite area is corrected to determine the amount of area chromatic aberration of magnification relating to the indefinite area.

A digital camera which performs digital processing on an image obtained by image capturing has a three-dimensional lattice point data table for image data conversion processing. The digital camera holds a matrix coefficient set for performing the conversion processing by matrix operation. In the respective lattice points of the three-dimensional lattice point data table, values corresponding to the conversion processing with the matrix coefficient set are set. Then a raw image file, including compressed image data obtained by lossy compression on the image data converted by the conversion processing and the held matrix coefficient set, as attendant information, is generated.

Image capturing apparatus, image processing apparatus and image processing method

An image pickup system causes a first illumination unit to emit light toward a subject at a first angle without causing a second illumination unit for emitting light toward the subject at a second angle different from the first angle, and causes an image pickup unit to capture the image of the subject so as to obtain a first captured image. The image pickup system causes the second illumination unit to emit light without causing the first illumination unit to emit light, and causes the image pickup unit to capture the image of the subject so as to obtain a second captured image. The image pickup system associates the first captured image with the second captured image.

A lens unitacquires identification information for an attached lens unit from the lens unit and stores the acquired identification information in a second memory. In a case in which correction information for the stored identification information is not registered, a CPUreads the correction information for the stored identification information out from an external memoryand registers it.

An image capturing apparatus having a three-dimensional grid data table holds a matrix coefficient which is a basis of the three-dimensional grid data table, and editing data for editing grid point data of the three-dimensional grid data table. To set the three-dimensional grid data table, the grid point data of the three-dimensional grid data table is calculated by performing a matrix operation using the matrix coefficient, and the calculated grid point data of the three-dimensional grid data table that is calculated based on the editing data is edited based on the editing data. Image data acquired by image capture is thus processed using the edited three-dimensional grid data table.

An image pickup apparatus including a photoelectric conversion element, first, a shutter speed for still-image pickup is set. Next, an image-pickup frame rate is set on the basis of the shutter speed for still-image pickup. Then, an operation of the photoelectric conversion element is controlled such that picked-up images are output at the set image-pickup frame rate. When the image-pickup frame rate that is set is higher than a moving-image-reproducing frame rate, a frame for use in a moving-image reproduction is generated from a plurality of frames of the picked-up images and reproduction is performed at the moving-image-reproduction frame rate.

An electrical signal output from an image sensing device is converted into digital image data and stored in a non-compressed form or a lossless-compressed form, in a storage medium. A user sets parameters associated with a white balance via a setting screen. The setting of the parameter is performed either in a first adjustment mode in which a color temperature is displayed as a parameter of the white balance is displayed together with the image data on the setting screen such that the user can adjust the color temperature or in a second adjustment mode in which a parameter of the white balance other than the color temperature is adjusted in a direction different from the direction in which the color temperature is adjusted. The image data is read from the storage medium and subjected to a white balance correction according to the parameters set via the setting screen.
