Abstract: An image processing apparatus includes an AWB gain calculation section that calculates a WB gain Gs and a hysteresis gain Gh for every frame, a WB correction section that performs WB correction using Gh, a control section that causes the WB correction section to perform the WB correction using a fixed gain Gf during lock of white balance, and a gain adjustment section that weights and adds a WB gain Gs(n) and a correction hysteresis gain Gh′(n−1) to calculate a correction hysteresis gain Gh′(n) after unlock of the white balance, and the control section causes the WB correction section to perform WB correction for a frame n using Gh′(n).

Abstract: An interchangeable-lens imaging apparatus includes a color-temperature-information calculation circuit and a white-balance-gain calculation circuit. The color-temperature-information calculation circuit calculates color-temperature information on the basis of a first white balance gain associated with a first lens unit and first lens information of the first lens unit. The first white balance gain is calculated on the basis of a signal output from an image sensor. The white-balance-gain calculation circuit calculates a second white balance gain associated with a second lens unit that is different from the first lens unit on the basis of the color-temperature information and second lens information acquired from the second lens unit.

Abstract: At least one processor configured as hardware generates gamma correction processing information based on an achromatic color input value and an output value acquired by referencing a three-dimensional LUT based on the achromatic color input value, references the three-dimensional LUT based on a representative input value as a chromatic color input value to acquire a representative output value, sets color difference signal processing information such that the representative output value is obtained when the representative input value is subjected to gamma correction processing and color difference signal processing, and subjects an image signal to gamma correction processing and color difference signal processing.

Abstract: An image processing apparatus includes: a gain calculating portion and a gain multiplication portion that perform signal enhancement with respect to an input image constituted by pixels having a plurality of color signals, with an intensity in accordance with signal values of each pixel, without changing a chroma and a hue; and a gamma correction portion that performs, for each pixel, tone conversion of a plurality of color signals that are subjected to signal enhancement, based on a weak gamma conversion curve in which a degree of gamma enhancement is weaker than in a basic gamma conversion curve which performs conversion such that a signal value of a halftone region at a time of outputting in a case where signal enhancement is not performed becomes a signal value in an appropriate output value range.

Abstract: An imaging apparatus includes an imaging unit, a first image processor, and a record processor. The imaging unit sequentially acquires image data groups comprising pieces of image data different in exposure conditions to generate HDR moving image frames. The first image processor subjects the pieces of the image data belonging to each of the image data groups to first composition processing, to generate HDR moving image data comprising HDR moving image frames. The record processor is configured to record image data for still images so that the pieces of the image data belonging to each of the image data groups are subjected to second composition processing different from the first composition processing, to generate HDR still image data.
