To realize an illumination control device and the like that can make color reproductivity of an image compatible with an S/N ratio at the time of infrared illumination, the illumination control device includes a visible light measurement unit configured to measure an amount of visible light components; an infrared illumination unit configured to perform infrared illumination; and a control unit configured to cause an intensity of the infrared illumination by the infrared illumination unit to gradually change as the amount of visible light components measured by the visible light measurement unit decreases from a first threshold to a second threshold.

Illumination control device, imaging device, and storage medium

An image capturing control apparatus includes a detection unit configured to detect a specific object area in an image captured by an image capturing apparatus, an acquisition unit configured to acquire a first input/output characteristic of the image capturing apparatus, a conversion unit configured to convert the image by acquiring a second input/output characteristic that is an inverse input/output characteristic to the first input/output characteristic, and by applying the second input/output characteristic to the image, and a control unit configured to control exposure of the image capturing apparatus based on a luminance value of the specific object area in the converted image.

Controlling exposure based on inverse gamma characteristic

There is provided with an information processing apparatus. An obtaining unit obtains an image. A first detecting unit detects a subject from the image. An exposure control unit controls an exposure based on a luminance of the detected subject. A second detecting unit detects a portion of the subject from the exposure-controlled image. A storing unit stores a difference between a first luminance of the detected subject and a second luminance of the portion of the detected subject.

Information processing apparatus, image capturing apparatus, method, and storage medium

An information processing device according to one embodiment of the present invention includes: a setting unit that sets a pattern used for outputting a partial image obtained from an omnidirectional image in accordance with the number and a position of at least one region of interest obtained from the omnidirectional image, which is a captured image captured by using a fisheye lens; an extract unit that, in accordance with a pattern set by the setting unit, cuts out a partial image including the region of interest from the omnidirectional image; a correction unit that performs a distortion correction process on the partial image cut out by the extract unit; and an output unit that, in accordance with the pattern set by the setting unit, outputs the partial image on which the distortion correction process has been performed by the correction unit.

An image pickup apparatus aims to control an illuminating part so as to obtain an image of good visibility irrespectively of a state of a zooming operation under dark environment. The image pickup apparatus has an image pickup part including a zoom lens, and a lens driving part configured to drive the zoom lens in an optical axis direction. The image pickup apparatus is capable of performing shooting by using an illuminating part configured to irradiate a subject with light. The image pickup apparatus comprises a control unit configured to control a dimming speed of the illuminating part according to drive information of the zoom lens.

Image pickup apparatus and control method thereof

A control apparatus obtains the moving speed of an object, and controls, based on the moving speed of the object, an image capturing unit configured to capture the object such that first image capturing for performing image capturing without following the object or second image capturing for performing image capturing while following the object is performed.

An image-taking apparatus changes a switching threshold value for switching between a color mode and a monochrome mode according to a maximum gain value set by a maximum gain setting unit so that switching between the color and monochrome modes can be optimally performed regardless of setting of the maximum gain value. The image-taking apparatus includes a threshold value correction unit configured to correct the switching threshold value according to the maximum gain value. The threshold value correction unit sets the switching threshold value with the maximum gain value set larger than an initial value to be smaller than the switching threshold value with the maximum gain value set smaller than the initial value.

Image-taking apparatus and method for controlling the same

A video processing method includes calculating mean values with respect to x coordinate value and y coordinate value of vertices that define a corresponding area, which is obtained when a designated area in spherical coordinates is projected on an xy coordinate plane that represents a captured image, and superimposing a mask image R on the captured image in such a way as to bring a point G having an x coordinate value and a y coordinate value identical to the calculated mean values with respect to the x coordinate value and the y coordinate value into coincidence with a point defined by a midpoint in the height direction and a midpoint in the width direction of the mask image.
