An image capturing apparatus comprises an operation device according to which a focal point detection region on a screen can be moved through a movement operation performed by a user; and a control unit configured to perform control such that a movement amount of the focal point detection region on the screen with respect to an operation amount of the operation device is changed according to a shooting state.

Provided is a video creation method in which, in a configuration in which a part of a captured video is extracted and displayed, the adjustment of an exposure amount and the video display in a case in which an extracted region is changed are appropriately executed. A video creation method according to an embodiment of the present invention includes setting, in an imaging region of a reference video having a first angle of view, a plurality of regions having a second angle of view smaller than the first angle of view, selecting a selection region of a recorded video from among the plurality of regions, reselecting the selection region from among the plurality of regions to switch the selection region, recording each of a pre-switching video and a post-switching video, displaying the post-switching video after the pre-switching video is displayed and displaying an insertion video in a period between a display period of the pre-switching video and a display period of the post-switching video, and adjusting, during a display period of the insertion video, an exposure amount and the like of a post-switching selection region.

A device includes a time-of-flight ranging sensor configured to transmit optical pulse signals and to receive return optical pulse signals. The time-of-flight ranging sensor processes the return optical pulse signals to sense distances to a plurality of objects and to generate a confidence value indicating whether one of the plurality of objects has a highly reflective surface. The time-of-flight sensor generates a range estimation signal including a plurality of sensed distances and the confidence value. The image capture device includes autofocusing circuitry coupled to the time-of-flight sensor to receive the range estimation signal and configured to control focusing based upon the sensed distances responsive to the confidence value indicating none of the plurality of objects has a highly reflective surface. The autofocusing circuitry controls focusing independent of the sensed distances responsive to the confidence value indicating one of the objects has a highly reflective surface.

This invention provides an integrated time-of-flight sensor that delivers distance information to a processor associated with the camera assembly and vison system. The distance is processed with the above-described feedback control, to auto-focus the camera assembly's variable lens during runtime operation based on the particular size/shape object(s) within the field of view. The shortest measured distance is used to set the focus distance of the lens. To correct for calibration or drift errors, a further image-based focus optimization can occur around the measured distance and/or based on the measured temperature. The distance information generated by the time-of-flight sensor can be employed to perform other functions. Other functions include self-triggering of image acquisition, object size dimensioning, detection and analysis of object defects and/or gap detection between objects in the field of view and software-controlled range detection to prevent unintentional reading of (e.g.) IDs on objects outside a defined range (presentation mode).

Safety markers are used to monitor the security situation surrounding a construction site. A position data set indicates a current position of a safety marker. A reference image data set indicates an initial state of the security situation, and a control image data set indicates a current state of the security situation. The position data set, the reference image data set and the control image data set are transmitted to a central processing unit. A correction data set is determined by evaluating the reference image data set and the control image data set. The position data set is corrected using the correction data set to generate a corrected position data set. The current position of the safety marker as indicated by the corrected position data set is compared to a target position of the safety marker. An alarm signal is generated if the current position deviates from the target position.

A device includes a time-of-flight sensor configured to transmit an optical pulse signal and to receive a return optical pulse signal corresponding to a portion of the transmitted optical pulse signal that has reflected off an object within a field of view of the time-of-flight sensor. The time-of-flight sensor generates a range estimation signal including a distance to the object and a signal amplitude indicating an amplitude of the return optical pulse signal. A controller is coupled to the time of flight sensor and is configured to process the range estimation signal over time to detect an input gesture based upon the signal amplitude and estimated distance.

A distance to a target to be read by image capture over a range of working distances is determined by directing an aiming light spot along an aiming axis to the target, and by capturing a first image of the target containing the aiming light spot, and by capturing a second image of the target without the aiming light spot. Each image is captured in a frame over a field of view having an imaging axis offset from the aiming axis. An image pre-processor compares first image data from the first image with second image data from the second image over a common fractional region of both frames to obtain a position of the aiming light spot in the first image, and determines the distance to the target based on the position of the aiming light spot in the first image.

A handheld electronic device includes a first camera unit, a laser focusing module and a control module. The laser focusing module is configured for radiating a laser signal and receiving a feedback signal induced by a reflection of the laser signal when the first camera unit is activated. The control module is coupled with the camera unit and the laser focusing module. The control module is configured for monitoring a strength level of the feedback signal or a response time between the laser signal and the feedback signal, and selectively generating a command to trigger the first camera unit according to the strength level or the response time.

Disclosed are a zoom method and an apparatus, to improve zoom accuracy of a camera module. The method includes: controlling, based on a target focal length, the lens to move in different subregions when the lens moves in an operation region, and determining position information of the lens based on a position detection relationship of a subregion in which the lens is currently located. The lens is controlled to move based on a position that is of the lens and that is detected when the lens moves, so that the lens can more accurately stop at a position corresponding to the target focal length. This helps improve focusing accuracy of the camera module.
