[Object] To estimate lens information with no change in photographing conditions. [Solution] An image processing apparatus according to the present disclosure includes: a positional displacement estimation unit configured to estimate positional displacement between a plurality of input images obtained by photographing an identical photographic subject; an alignment processing unit configured to align positions of the plurality of input images on the basis of the estimated positional displacement; and a lens information estimation unit configured to estimate information of a lens used to photograph the input image depending on a model indicating a deterioration component of the lens on the basis of the aligned input images.

Image processing apparatus and image processing method

An image processing apparatus including: a scene recognition section recognizing a scene captured by an image; an assigning section selecting a change-target parameter being an adjustment parameter whose parameter value is to be changed from a plurality of adjustment parameters adjusting the image in response to the scene of the image, and assigning the parameter to a specific operation section being a specific operation section out of user-operable operation sections; and a parameter setting section setting a parameter value of the change-target parameter assigned to the specific operation section in response to operation of the specific operation section by a user.

Image processing apparatus, image processing method, program, and recording medium

An amplifier gain setting section estimates a light source parameter which relies upon a spectral distribution of an image pickup light source based on an image signal. Then, a first adjustment control value for each color signal when adjustment is to be performed so as to establish a white balance based on the estimated parameter is modulated by an amount corresponding to a follow-up sensitivity toward a second adjustment control value when adjustment is to be performed so that an achromatic subject under a particular reference light source is reproduced as an achromatic subject. The modulated adjustment control value is set to a white balance amplifier. The follow-up sensitivity is set to the amplifier gain setting section in response to an illuminance level estimated from a detection value of the brightness.

Image processing apparatus, method, program and image pickup apparatus

An image capturing apparatus whose lens unit can be attached to and detached from a camera body section includes: an image-capturing signal processing section that generates an image signal by performing an image capturing process of subject light introduced via the lens unit; an attachment detecting section that generates a detection signal indicating whether or not the lens unit is attached to the camera body section; and a control section that determines whether or not the lens unit has been interchanged or detached and attached by using the detection signal, and performs a process of forming index data with respect to the image signal on the basis of a result of the determination.

Image capturing apparatus, image capturing method, and program

A signal processing apparatus corrects color mixture between pixel cells in a solid-state imaging device in which the pixel cells including photoelectric transducers are two-dimensionally arranged in an array and in which color filters having primary color components for generating luminance components and other color components are arranged over the pixel cells. The signal processing apparatus includes correction processing means for performing the correction to the signal from a target pixel by using the signals from multiple neighboring pixels adjacent to the target pixel in the solid-state imaging device and correction parameters independently set for the signals.

Signal processing apparatus for solid-state imaging device, signal processing method, and imaging system

An imaging method and an imaging apparatus are provided in which information about white points determined is stored and operation is performed only between the stored white points. The imaging method includes the steps of: automatically or manually determining at least two white points (Steps S-, S-and S-); storing the above described at least two white points determined (Steps S, Sand S); and manually or automatically adjusting a white point with the range between the above described at least two white points stored as a white point adjustment range (Step S).

Imaging method and imaging apparatus

The present invention relates to an image pickup device including: a detecting unit for detecting a position of a filter for changing light separation; and a white balance controlling unit for performing white balance control on a basis of the position of the filter detected by the detecting unit.

Image pickup device and method

A white balance controlling apparatus can discriminate a green subject under a light source of the sun and a white subject under a fluorescent light source without the addition of a new color filter. The maximum or average value of luminance at a first portion of an image signal for one frame or field which includes pixels discriminated as pixels of green under a light source of the sun or white under a fluorescent light source is compared with that at any other portion of the image signal. If the maximum or average value of luminance at the first portion is either lower or higher than that at the other portion, then it is estimated that either a light source of the sun or a fluorescent light source is used.

White balance controlling apparatus, method, program, and image pickup apparatus

To eliminate an amplitude difference between luminance signals from pixels included in horizontal lines of color filters, caused by a sensitivity difference from one photosensor to another in a CCD, and reduce a horizontal stripe-like noise appearing in a monitoring image and captured image, there is provided an arithmetic circuit to calculate an amplitude difference in Gr and Gb signals based on an output from a four-channel detector to set gains multiplied by compensation factors, respectively, with which the white balance-processed Gr and Gb signals are equal in amplitude to each other, thereby controlling the gain of a while balance amplifier.
