An image processing apparatus obtains an image captured in an image capturing and sets a white balance recording mode for recording the image as a still image and a white balance display mode for displaying the image before being captured as the still image on a display. The apparatus controls white balance correction performed on the image captured in the image capturing. In a case where a first display mode that is included in the display mode is set, the apparatus sets an amount of a light source color that remains after the white balance correction is performed on the image before being captured as the still image in the first display mode to be larger than the amount of the light source color that remains after the white balance correction is performed on the still image in the recording mode.

Image processing apparatus, control method thereof, and storage medium

An image processing apparatus includes a detection unit configured to detect two or more specific objects from a captured image, a first color estimation unit configured to estimate a first light source color from color information about a first specific object among the detected specific objects, a second color estimation unit configured to estimate a second light source color from color information about a second specific object among the detected specific objects, a third color estimation unit configured to estimate a third light source color from color information about an area including other than the detected specific objects, and a calculation unit configured to calculate a white balance correction value to be applied to the captured image by assigning a weight to at least one of the first, second, and third light source colors based on degrees of similarity between the first, second, and third light source colors.

Image processing apparatus, image processing method, and storage medium

An object is to provide an image with optimal white balance correction in photographing under a flicker light source, regardless of the shutter speed. Provided is an image processing apparatus including a white balance correction unit that extracts data of a predetermined color extraction range from a captured image to estimate a light source color and that uses a white balance correction value adapted to the estimated light source color to apply white balance correction to the captured image, the image processing apparatus including a shifting unit that shifts the color extraction range according to a shutter speed applied to imaging of the captured image.

Image processing apparatus, information processing method and program

An image processing apparatus capable of properly synthesizing a strobe-illuminated image and non-strobe-illuminated images, irrespective of a condition for illuminating a photographic subject. A sensitivity of strobe emission photographing is set to be lower than a sensitivity of non-strobe emission photographing, and a strobe-illuminated image and plural sheets of non-strobe-illuminated images are continuously photographed with the set sensitivities. The strobe-illuminated image is gain-processed with a gain amount, and positional deviations of the plural sheets of non-strobe-illuminated images relative to the strobe-illuminated image are corrected. An averaged image obtained by synthesizing the gain-processed image and the images after the positional deviation correction is synthesized with the strobe-illuminated image, while taking account of amounts of strobe illumination in the strobe-illuminated image, thereby obtaining a synthesized image.

Image processing apparatus and image processing method for performing image synthesis

A parameter for each of a plurality of images captured in time series is computed based on information obtained from the image, and a normal reference image (an image captured before an image targeted for processing is stored). A degree of similarity between the image targeted for processing and the normal reference image is computed, and a parameter to be used in image processing applied to the image targeted for processing is computed by performing weighted addition such that a parameter computed from the normal reference image has a higher weight than a parameter computed from the image targeted for processing the higher the degree of similarity.

Image processing apparatus and control method therefor

An image processing apparatus includes a reading unit configured to read an image and information about a target portion recorded along with the image, a correction unit configured to correct distortion occurring in the image, and a recording control unit configured to re-record the information about the target portion which has been changed according to a distortion correction amount performed on the image by the correction unit.

Image processing apparatus, control method, and program

A file editing apparatus is provided that edits a color-image processing file in which limitations can be imparted on the display of edit history information that corresponds to a new shooting mode. The apparatus includes an editing unit that edits a color processing file; a display control unit; and a storage unit that stores the color-image processing file including edit history information of the color processing file edited by the editing unit, and edit history display control information for the display control unit to control display of the edit history information.

Apparatus and methods for creating and/or editing color-image processing files

An image processing apparatus which includes an image processing unit and a system control unit, wherein this system control unit adds information for determining an image height reference position of an image before cropping processing is performed to an image cropped by the image processing unit, and records the resultant image in an external storage device. Alternatively, information for determining an image height reference position of an image before rotation processing is performed is added to an image rotated by the image processing unit, and the resultant image is recorded in an external storage device.

Image processing apparatus and image processing method

A system setting an image processing parameter in an imaging apparatus and an information processing apparatus, downloads a parameter file from an external apparatus, and sets in the imaging apparatus an image processing parameter included in the parameter file downloaded from the external apparatus. In the information processing apparatus, image data is processed using the image processing parameter included in the parameter file. Thus, the information processing apparatus and the imaging apparatus can perform image processing using an image processing parameter obtained from one downloaded parameter file.

Image processing file setting system

An image processing apparatus includes a spectrum estimation unit for estimating a spectrum for each pixel from multiband image data comprising image data in multiple different wavelength ranges; a memory for storing spectral data suitable for each of multiple different shooting modes; and a conversion unit for determining a shooting mode of the multiband image data and converting the spectrum into band data with different spectral characteristics using the spectral data stored in the memory, the spectral data suitable for the determined shooting mode.

Image processing apparatus, image processing method, and image sensing apparatus

An image pickup apparatus which can carry out proper white balance adjustment even at the time of bounce flash shooting. A white balance adjusting circuit uses a first correction value calculated based on shot image data as a white balance correction value when it is detected that no light has been emitted from the light emitting device, and uses a second correction value for shooting with light emission as the white balance correction value when it is detected that light has been emitted from the light emitting device. The white balance adjusting circuit uses a third correction value different from the second correction value as the white balance correction value, when a white balance photography determining section detects that the bounce flash photography has been carried out.

Image pickup apparatus, white balance adjustment method therefor, and program for implementing the method

In an image capturing system, such as a digital still camera, different types of color spaces are set, and, in response to one image-capturing instruction from a user, identification information identifying different types of color spaces is stored in a form associated with the image data, which is automatically input. Based on the identification information for the image data, the image data is displayed for each type of color space.
