Systems and methods for macro stereo time-lapse photography, producing a stereographic time-lapse digital video, and macro stereographic time-lapse digital videos. A method of producing a sequence of time-lapse stereographic images of a subject, by positioning a camera with a macro lens at a first position relative to the subject; using the camera to obtain a first stack of images of the subject from the first position; positioning the camera at a second position relative to the subject; using the camera to obtain a second stack of images of the subject from the second position; and storing the first stack of images and the second stack of images as a stack pair; and then selectively repeating.

An imaging device according to the present disclosure includes an exposure section and a controller. The controller controls, at an exposure timing based on a predicted exposure timing at which a state of a subject shot at a first frame rate is predicted to satisfy a predetermined condition, the exposure section at a second frame rate. The second frame rate is different from the first frame rate.

Techniques to improve a digital image capture device's ability to stabilize a video stream—while enforcing desired stabilization constraints on particular images in the video stream—are presented that utilize an overscan region and a look-ahead technique enabled by buffering a number of video input frames before generating a first stabilized video output frame. More particularly, techniques are disclosed for buffering an initial number of input frames so that a “current” frame can use motion data from both “past” and “future” frames to adjust the value of a stabilization strength parameter and/or the weighted contribution of particular frames from the buffer in the determination of stabilization motion values for the current frame. Such techniques keep the current frame within its overscan and ensure that the stabilization constraints are enforced, while maintaining desired smoothness in the video stream. In some embodiments, the stabilization constraint may comprise a maximum allowed frame displacement.

Diffuse image measurement system and digital image formation method. The system includes a source of light with time-varying intensity directed at a scene to be imaged. A time-resolved light meter is provided for receiving light reflected from the scene to generate time-resolved samples of the intensity of light incident at the light meter. The temporal variation in the intensity of light incident at the light meter is associated with a function of a radiometric property of the scene, such as a linear functional of reflectance, and a computer processes the samples to construct a digital image. The spatial resolution of the digital image is finer than the spatial support of the illumination on the scene and finer than the spatial support of the sensitivity of the light meter. Using appropriate light sources instead of impulsive illumination significantly improves signal-to-noise ratio and reconstruction quality.

An electronic device and a method for controlling same are disclosed. The electronic device includes a first camera having a first lens with a first focal distance, a second camera including a second lens having a second focal distance different from the first focal distance, a memory, and a processor which: acquires information on a first object included in a first image acquired by capturing surroundings of the electronic device through the first camera if it is identified, based on of the acquired information on the first object, that information on a second object associated with the first object exists, acquires a second image through the second camera and based on whether the second object is included in the acquired second image, determines a point of time when high-speed image capture is to be performed using the first camera.

One example is a shock gauge system for measuring an external blast to a hull. The shock gauge system includes at least one accelerometer to produce acceleration data in response to the external blast, a mass with an accelerometer affixed to it, a crush block, a linear displacement potentiometer (LDP), a camera, and a processor logic. The LDP device generates displacement data of a mass being pushed into the crush block when reacting to the external blast. The camera captures images of movement of the mass. The processor logic verifies if the acceleration data is valid by correlating the acceleration data to the displacement data, the images, and/or an amount of displacement into the crush block by the mass. When the acceleration data is valid, the acceleration data may be used to create a more blast resistant hull.

An apparatus and method for recording a scene using two lighting setups in alternation so as to concurrently record motion picture footage of the scene for each lighting setup, the footage for the two lighting setups having minimized motion offset. The apparatus includes: a plurality of light sources, a controller to define two lighting setups using the plurality of light sources, and to actuate the lighting setups in alternation, a camera to capture a sequence of frames showing the scene illuminated by one of the two lighting setups in alternation, and optionally a processing module to process the sequence of frames to generate two clips of footage of the scene, each corresponding to a lighting setup. The timing of actuation of the lighting setups relative to the frame boundaries avoids the need to use optical flow algorithms to remove motion artifacts, and the need for a specialized high speed camera.
