An image capturing apparatus capable of guaranteeing the authenticity of contents while reducing the calculation load of a hash value of an image file. The image capturing apparatus generates an image file, and performs processing for reducing a file size of the image file. A hash value generation section calculates a hash value by applying a hash function to the processed image file. Reduction processing information indicating a method of reducing the file size is generated, and the image file, the hash value, and the reduction processing information are transmitted in a state associated with each other, to a management system that registers data associated with the image file including the hash value in a blockchain.

An information processing device is capable of causing a user to visually recognize a real space via a display. The information processing device recognizes a particular hand gesture performed by the user. The information processing device 1) displays a first frame in accordance with the particular hand gesture on the display, and 2) continues displaying the first frame for at least a predetermined amount of time after the particular hand gesture is recognized, even in a case where a state transitions to a state where the particular hand gesture is not recognized after the first frame is displayed The information processing device, in a state where the first frame is displayed on the display, executes particular processing with regard to a range of the real space indicated by the first frame out of the real space.

Information processing device and information processing method

An imaging system includes a terminal device that includes an imaging sensor, and a head mounted display device that receives an image captured by the imaging sensor from the terminal device and displays the captured image. The imaging system includes at least one memory and at least one processor which function as: a detecting unit configured to detect the display device from the captured image; and a display control unit configured to control display of the captured image on the display device, based on a detection result of the display device using the detecting unit.

Image system and method for controlling imaging system

An image capturing apparatus comprises an image sensor, and a controller that controls the image sensor to shoot images for display at a first cycle and controls to shoot a still image in response to the image shooting instruction. In a case where continuous shooting of still images is instructed during shooting the images for display at the first cycle, the controller changes a cycle at which the images for display are shot to a second cycle which corresponds to an integer multiple of speed of the continuous shooting while e continuous shooting is performed, and controls the image sensor to shoot the still images at the speed of the continuous shooting and shoot the images for display at the second cycle.

Image capturing apparatus and control method thereof

An image capture apparatus comprising an image sensor is disclosed. When an instruction to shoot a still image has been detected when executing a live view display, the image capture apparatus shoots the still image preferentially, while repeatedly displaying a same image during a period in which the live view display cannot be updated. The image capture apparatus reduces a luminance and/or changes a tone of the image that is repeatedly displayed.

Image capture apparatus and control method thereof

An image capturing apparatus comprising an image sensor and a control circuit is disclosed. The control circuit changes, if a second drive period that is a drive period of the image sensor for still image shooting overlaps with a first drive period that is a drive period of the image sensor for moving image shooting, a start timing of the second drive period. When performing still image shooting while performing moving image shooting and moving image display: if the still image shooting is single image shooting or a first shot of continuous shooting, the control circuit does not change the start timing of the second drive period. If the still image shooting is a second shot onward of continuous shooting, the control circuit changes the start timing of the second drive period with giving priority to the moving image display.

Image capturing apparatus and control method therefor

There is provided an image capturing control apparatus. A first control unit performs control to repeatedly obtain an evaluation image using an image sensor. The evaluation image is used to obtain an evaluation value for controlling at least one of image capturing and development. An obtaining unit obtains the evaluation value on the basis of the evaluation image. A second control unit performs control to temporarily stop the obtainment of the evaluation image and use the image sensor to obtain, during a stopped period, a still image for recording. A generating unit generates an estimated evaluation image corresponding to the stopped period on the basis of two or more evaluation images obtained outside the stopped period. For the stopped period, the obtaining unit obtains the evaluation value on the basis of the estimated evaluation image.

An image processing apparatus comprises: a dividing unit that divides two frame images into a plurality of divided areas; a determination unit that determines a representative point for each of the divided areas in one of the two frame images; a setting unit that, for each of the two frame images, sets image portions for detecting movement between the two frame images, based on the representative points; and a detection unit that detects movement between the two frame images based on correlation values of image signals in the set image portions, wherein for each of the divided areas, the determination unit determines a feature point of the divided area or a predetermined fixed point as the representative point of the divided area in accordance with a position of the divided area in the one frame image.

Image processing apparatus and method

An image capturing apparatus comprises: an image sensor having multiple segmental pixels each including multiple photoelectric conversion units arranged two-dimensionally for receiving light beams that have passed through different pupil regions, the photoelectric conversion units being divided for each segmental pixel in a first or second pupil-division direction for addition reading; a determination unit configured to determine an edge direction of an image for each divided area of the image sensor; a decision unit configured to, based on the determined edge direction, decide for each divided area either the first or second pupil-division direction; a reading control unit configured to perform addition reading of the segmental pixels by dividing the photoelectric conversion units in the first or second pupil-division direction decided, and to control the image sensor such that pairs of image signals are outputted; and a focus adjusting unit configured to carry out phase difference focus adjustments.

When calculating the amount of color blur suppression based on gradient values at edge portions of image data, the degree of color blur suppression has been different between a non-addition readout method and an addition readout method even with an identical subject. To solve this problem, there is provided an image processing apparatus that calculates a suppression coefficient so as to suppress color blur when a gradient value exceeds a threshold value, and sets up the threshold value so that the gradient value range required for color blur suppression when an image sensor is driven by the addition readout method to generate image data is wider than the gradient value range required when the image sensor is driven by the non-addition readout method.
