Image shake correction device, optical apparatus, imaging apparatus, and control method
There is provided with an image shake correction device that controls an image correction unit and corrects an image shake of a captured image. The image shake correction device calculates a first correction amount to be used for correcting the image shake while shooting moving images and a second correction amount to be used for correcting the image shake while shooting still images based on a shake detection signal. The image shake correction device selects the correction amount to be used for correcting the image shake from either the first correction amount or the second correction amount and executes a control that updates an intermediate calculation value of the calculation unit corresponding to the correction amount that has not been selected from either the first calculation unit or the second calculation unit, with a value of the correction amount that has been selected.

An imaging device comprises an image data acquisition circuit for forming a subject image while shifting focus position by a given amount and acquiring a plurality of image data, an image selection circuit for selecting images to be combined based on shift amount of focus position when image data was acquired by the image acquisition circuit, and image data resolution, and an image combination circuit for combining the plurality of image data that was selected by the image selection circuit, to generate image data having a large depth of field.
Image pickup apparatus and control method thereof
A network camera includes a pan driving unit and a tilt driving unit for changing a shooting direction of an imaging unit. A detection unit detects rotation angles of movable units to be driven by the pan driving unit and the tilt driving unit. A pan/tilt control unit corrects a target position of the movable unit according to a correction value according to the detected rotation angle and controls each of the driving units using a value after the correction. In addition, when masked image drawing for processing an image is performed so that a partial image of a predetermined position is not visible in the image captured by an imaging unit, an image processing unit performs a process of correcting a rotation angle detected by the detection unit according to the correction value and drawing a masked image at a mask drawing position after the correction.
IMAGE PICKUP APPARATUS
An image pickup apparatus having: an image sensor, having an image pickup plane, configured to photoelectrically convert a subject image formed on the image pickup plane to an image signal; a driving actuator configured to rotatably move the image sensor relative to a rotation axis passing through the image pickup plane; an angular velocity detection sensor configured to detect a rotational angular velocity of the image sensor about the rotation axis; a first shutter configured to control an exposure time of the image sensor; a second shutter configured to control the exposure time of the image sensor; and one or more processors configured to: control the driving actuator to reduce rotational shake around the rotation axis based on the rotational angular velocity; and select one of the first shutter and the second shutter to control the exposure time of the image sensor based on the rotational angular velocity.
ACCESSORY APPARATUS, IMAGE-CAPTURING APPARATUS, CONTROL APPARATUS, LENS APPARATUS, CONTROL METHOD, COMPUTER PROGRAM AND STORAGE MEDIUM STORING COMPUTER PROGRAM
The accessory apparatus provides, with an image-capturing apparatus, a notification channel used for providing a notice from the image-capturing apparatus to the accessory apparatus, a first data communication channel used for data transmission from the accessory apparatus to the image-capturing apparatus, and a second data communication channel used for data transmission from the image-capturing apparatus to the accessory apparatus. An accessory controller acquires from a timer, in response to receiving a transmission request as the notice, a first time of receiving the transmission request and acquires, in response to receiving a specific command through the second data communication channel from the image-capturing apparatus, accessory information corresponding to the first time or a second time acquired based on the first time. The accessory controller transmits the accessory information to the image-capturing apparatus through the first data communication channel.
Electronic image stabilization frequency estimator
Disclosed are a system and a method for determining enabling or disabling electronic image stabilization (EIS) for a video frame. An image sensor of a camera system captures a video stream that comprises a plurality of video frames. An image processor determines availability of a computational resource that may process application of EIS on each video frame. Simultaneously, the image processor receives motion data of the camera system from a gyroscope. Based on the computational resource availability, a motion frequency threshold is determined. Based on the gyroscope motion data, a motion frequency of each video frame is estimated. The estimated motion frequency is compared to the determined motion frequency threshold. If the estimated motion frequency is greater than the determined motion frequency threshold, application of EIS is disabled. If the estimated motion frequency is less than or equal to the determined motion frequency threshold, application of EIS is enabled.
Image shake correcting device and control method therefor, optical apparatus, and image pickup apparatus
This image pickup apparatus performs feedback control so that a position of a shake correcting lens converges to a target position. A LPF and a subtracting unit divide a shake signal into low-frequency and high-frequency components. An adding unit combines each output of a high-frequency LPF and a low-frequency LPF and output the target position. A pan/tilt determination unit determines a panning speed from the shake signal. If the panning is fast, the target positions of the low-frequency and the high-frequency are controlled to converge to 0, and calculation for the target position of the high-frequency starts before that of the low-frequency at the end determination. If the panning is slow, only the target position of the low-frequency is controlled to converge to 0. The pan/tilt determination unit changes a determination condition for the detection depending on whether it is at the handheld photographing or the static state.
Methods and systems for determining a direction of a sweep motion
In one embodiment, an image-capturing device includes a camera, one or more motion-estimating devices to detect motion data for the device, and a processing system which is configured to automatically estimate a first direction of a sweep motion of the image-capturing device based on the motion data. The processing system is further configured to automatically estimate a second direction of the sweep motion of the image-capturing device based on images captured by the image-capturing device and to automatically select the first direction or the second direction of the sweep motion.
