An imaging apparatus includes an imaging element; a mechanism capable of changing a relative position between the imaging element and an object image; a deterioration degree estimation unit that estimates a degree of deterioration through time for each region of the imaging element; a luminance value acquisition unit that acquires a luminance value of a screen corresponding to a first region that is the region in which the degree exceeds a predetermined first threshold, as a first luminance value; a control amount calculation unit that calculates, in a case where the first luminance value exceeds a predetermined first luminance value in a luminance value distribution of an entire screen corresponding to the imaging element, a first control amount of the mechanism in which an object having the predetermined first luminance value or less is allocated to the first region based on the luminance value distribution; and a system control unit that controls the mechanism based on the first control amount.

Imaging apparatus, method, and storage medium

An image processing apparatus comprises one or more processors and one or more memories containing instructions that, when executed by the one or more processors, cause the one or more processors to function as a specification unit configured to, based on a parameter of an image capturing unit, specify a region captured by the image capturing unit in a display screen in which display panels are arrayed, and a correction unit configured to, based on a direction from a pixel in the region to the image capturing unit, obtain a correction amount of a luminance value of the pixel, and based on information for correcting an individual difference regarding a luminance of a display panel, correct the correction amount.

Image processing apparatus that corrects luminance values in pixels in a specified display region using a correction amount based on vectors between a pixel and an image capture apparatus

An image pickup apparatus capable of suppressing occurrence of a delay in an exposure control when the exposure control is performed by selectively changing an exposure condition among a plurality of exposure conditions. In a transition period from when the exposure control for changing a first exposure condition according to a target exposure at a time of image pickup of the subject is started until the exposure reaches the target exposure, another exposure condition other than the first exposure condition is changed so that an exposure changing speed of the first exposure condition is compensated for. When the exposure is changeable based on a program diagram and when the first exposure condition is changed, control is provided so that a second exposure condition to be changed immediately after changing the first exposure condition is used to compensate for the exposure changing speed of the first exposure condition.

An image capture apparatus that allows the user to easily change the brightness of an image that is shot while using automatic exposure control is disclosed. The image capture apparatus comprises a setting unit configured to be able to set a reference value of proper exposure. The image capture apparatus determines exposure conditions based on the luminance information and the reference value, wherein the reference value is a value used as a reference exposure value from which exposure conditions are varied in an exposure compensation.

Image capture apparatus and control method thereof

An image processing apparatus comprises: a conversion unit configured to convert a characteristic of an image signal; and a display control unit configured to generate information indicating a relationship of image signals before and after conversion is performed by the conversion unit, and cause a display to display the information indicating a relationship of image signals, wherein the display control unit generates the information indicating a relationship of image signals, so as to include information indicating a relationship of scales of signals before and after conversion and information indicating a relationship of signal values before and after conversion.

Image processing apparatus, control method thereof, and storage medium

A view angle control apparatus includes: a view angle change unit to change the view angle of an image; a control unit to perform first control where the view angle change unit changes the view angle from a first view angle to a second view angle that is by a predetermined amount to a wide-angle direction relative to the first view angle, according to a first determination, and perform second control where the view angle change unit changes the view angle to the first view angle, according to a second determination, after the first control; and an operating member to accept an operation of changing a setting of the predetermined amount, and upon an operation having been performed through the operating member between start of the first control and start of the second control, the control unit performs the second control after changing the setting of the predetermined amount.

View angle control apparatus and view angle control method

An image capturing apparatus includes an image capturing unit for capturing an object image; an adjustment unit for adjusting the exposure of the image capturing unit; a detection unit for, in the case where the image capturing unit is saturated with respect to light that is input, detecting a signal level corresponding to the highest level of incident light in the image capturing unit after the adjustment unit reduces the exposure of the image capturing unit so as to reduce saturation; and a control unit for, in the case where the exposure of the image capturing unit is reduced by the adjustment unit, controlling the adjustment unit such that, among a plurality of methods for changing the exposure, a method having a faster response speed in response to an instruction to change the exposure is given priority and used.

Image capturing method and apparatus, with reduced saturation and improved signal-to-noise ratio based on a dynamic range

A remote-control apparatus which remotely controls an image capturing apparatus, comprises a communication unit configured to communicate with the image capturing apparatus; a reception unit configured to receive video data and a parameter obtained at the time of shooting of video from the image capturing apparatus via the communication unit; a display unit configured to display the video data; a designation unit configured to designate an area of the video displayed by the display unit; an acquisition unit configured to acquire predetermined information from video data of the designated area; and a transmission unit configured to transmit the predetermined information and the parameter to the image capturing apparatus via the communication unit.

Remote-control apparatus and control method thereof, image capturing apparatus and control method thereof, and system

An image capturing apparatus comprising an object detection unit which detects a specific object from an image signal, and a control unit which performs first control corresponding to the specific object when the object detection unit detects the specific object, and performs second control different from the first control when the object detection unit does not detect the specific object, wherein when a state in which the specific object is detected by the object detection unit transits to a state in which the specific object becomes undetectable, the control unit changes, based on information before the specific object becomes undetectable, at least either of a time for which the first control is held and a transition speed when transiting from the first control to the second control.
