A system or method includes a platform to allow users to coordinate images captured by a separated worn camera with images captured by a held camera, displaying such images at real-time to a user through a user interface on the held camera or a user interface on a separate device. The separate worn camera is contemplated to provide a separate image feed to provide one or more augmentations to an image captured by the held camera.

The present disclosure relates to a method, apparatus, device and storage medium for controlling video playback speed. the method includes: receiving a speed adjustment instruction; determining, according to correspondence relationship between the speed adjustment instruction and time length, a first time length corresponding to the speed adjustment instruction; obtaining first video data through an image acquisition apparatus according to the first time length; and compositing the first video data and second video data according to a second time length to obtain third video data, where the second time length is playback time length for the third video data, and a playback screen for the third video data includes a playback screen for the first video data and a playback screen for the second video data The method for controlling the video playback speed proposed in the present disclosure may enable a user to control the playback speed of the recorded video in the composited video on the terminal according to the input speed adjustment instruction.

An image capturing apparatus for intermittently acquiring first images for use in generating a time lapse moving image, from among images corresponding to frames included in a moving image. The image capturing apparatus includes a target value setting unit configured to, based on a result of photometry, set a target value regarding an exposure when an image is acquired, a control value calculation unit configured to calculate a control value with respect to each frame regarding the exposure when brightness is changed toward the target value, and a control unit configured to control the exposure based on the control value. In a predetermined period before each first image is acquired, the control unit changes the exposure by a first degree of change, and outside the predetermined period, the control unit changes the exposure by a second degree of change different from the first degree of change.

A video processor chip includes a memory circuit, a frame rate converter circuit, and an image compensation circuit. The memory circuit includes first to third storage spaces. The frame rate converter circuit sequentially writes multiple frame data in video data to the first to the third storage spaces respectively, and reads second data in the frame data from the memory circuit to perform a frame rate conversion when first data in the frame data is written to the memory circuit. The second data is a previous frame data of the first data. The image compensation circuit reads third data in the frame data from the memory circuit when the frame rate converter circuit reads the second data, and performs an image compensation according to a difference between the second data and the third data. The third data is a previous frame data of the second data.
