An image processing apparatus (100) includes: a variable determination unit (134) that performs, based on a distribution of luminance values of individual pixels included in a predetermined area determined according to information regarding a motion of a user out of first video data recorded in a first dynamic range, determination of a variable to be used to calculate the luminance values of the individual pixels when the first dynamic range is converted into a second dynamic range; and a converter (135) that converts the first video data into second video data displayed in the second dynamic range, based on the variable determined by the variable determination unit.

A method and system for video recording are provided, the method including: reading an audio data stream of a target video in real time, and converting a video picture of the target video into a video frame data; monitoring a play state of the target video, recording a start time node when the play state indicates that the live broadcast is paused, and recording an end time node when the play state indicates that the live broadcast is resumed; calculating an amount of a to-be-inserted data based on the start time node and the end time node, and inserting an audio null packet data with an amount equal to the calculated amount before the audio data stream when the live broadcast is resumed; and synthesizing the audio data stream into which the audio null packet data is inserted and the video frame data into a recorded video file.

The present disclosure discloses an image decryption method that includes steps outlined below. Control information in an image stream is read and decrypted. Image stream packets in the image stream are read according to the control information. According to the control information, pixel data of a first reference frame from a first temporary storage block of a memory module and/or of a second reference frame from a second temporary storage block of the memory module are selectively read. A decryption process is performed according to the image stream packets and selectively according to the pixel data of the first and/or the second reference frame to generate pixel data of a decrypted frame. During the decryption process, the pixel data of the decrypted frame is transmitted to a post-processing circuit and is stored to one of the first and the second temporary storage blocks according to the control information.

A video processing method includes: receiving a video stream from a camera component; converting the video stream into at least one first data packet, where the at least one first data packet is independently encoded or decoded; and storing a first data packet obtained in a first reporting cycle as a first video clip.

A method includes recording a first video stream characterized by a first value of a first quality characteristic. The method includes determining that the first video stream satisfies a trigger criterion. The trigger criterion characterizes a threshold amount of video content change information. The method includes, in response to determining that the first video stream satisfies the trigger criterion, obtaining a second video stream characterized by a second value of a second quality characteristic. The second video stream includes scene information also included in the first video stream. The second value of the second quality characteristic is indicative of a higher quality video stream than the first value of the first quality characteristic. The method includes generating a third video stream by adding information from the second video stream to the first video stream. The third video stream corresponds to a higher quality version of the first video stream.

An image data storage device 101 acquires a plurality of images (step S201), identifies metadata common among two or more images of the plurality of images (step S205), and stores the plurality of images into an image file conforming to an image file format and also stores the common metadata into the image file (step S210).

In a method for superimposing a prerecorded media file into a video, a video of a scene is displayed on a display device of a mobile electronic device. A prerecorded video file to render on the display device is received. The prerecorded video file is superimposed over the video, such that the video is partially obscured by the prerecorded video file. The prerecorded video is played file while displaying the video, such that the prerecorded video file and a non-obscured portion of the video are rendered simultaneously.

A data acquisition and recording system (DARS) and viewer for mobile assets that includes a data encoder, onboard data manager, and at least one local memory module. DARS processes video data from at least one 360 degree camera and stores a compressed record of the data at least once per second in the local memory module. DARS is designed to run in near real-time mode, storing a full record comprising five minutes of data to a remote memory module every five minutes, and in real-time mode, streaming video data to the remote memory module by uploading a record of data at least once per second and up to once every tenth of a second. Remotely located users can view video, audio, and data in various view modes through a web browser or virtual reality device, which provides for quicker emergency response, validate the effectiveness of repairs and rerouting, and monitor crew performance and safety.

A video processing system includes: an object movement information acquiring means for detecting a moving object moving in a plurality of segment regions from video data obtained by shooting a monitoring target area, and acquiring movement segment region information as object movement information, the movement segment region information representing segment regions where the detected moving object has moved; an object movement information and video data storing means for storing the object movement information in association with the video data corresponding to the object movement information; a retrieval condition inputting means for inputting a sequence of the segment regions as a retrieval condition; and a video data retrieving means for retrieving the object movement information in accordance with the retrieval condition and outputting video data stored in association with the retrieved object movement information, the object movement information being stored by the object movement information and video data storing means.
