Systems and methods for previewing newly captured image content and reviewing previously stored image content using an electronic device are provided. The previously stored image content may include an individual distinct image or at least two consecutive video frame images.

An image detection method determines a target object. A plurality of original images of a scene in front of a vehicle are obtained. An object in one original image is detected, and a degree of similarity between the object in the original image and the target object in a preset image is calculated. If the degree of similarity is greater than a preset similarity threshold, it is determined that the original image is a target image and the object is the target object. A position of the target object relative to the vehicle is determined and output. The method can recognize objects of interest in front of a driver.

The present disclosure provides an image encoder. The image encoder is configured to encode an original image and reduce compression loss. The image encoder comprises an image signal processor and a compressor. The image signal processor is configured to receive a first frame image and a second frame image and generates a compressed image of the second frame image using a boundary pixel image of the first frame image. The image signal processor may include memory configured to store first reference pixel data which is the first frame image. The compressor is configured to receive the first reference pixel data from the memory and generate a bitstream obtained by encoding the second frame image based on a difference value between the first reference pixel data and the second frame image. The image signal processor generates a compressed image of the second frame image using the bitstream generated by the compressor.

The present disclosure provides a video synthesis method, apparatus, computer device and computer-readable storage medium, which the method includes: acquiring a first video; capturing second video data photographed in real time; performing first encoding on the second video data to obtain an encoded video; synthesizing the first video and the encoded video to obtain synthesized video data; and performing second encoding on the synthesized video data to obtain a target video. By means of the method, there is less loss in the obtained target video frames and a relatively high definition of the video frames.

A control unit of a vehicle traveling data recorder acquires the position of a vehicle. Further, the control unit acquires a captured image generated by a camera which photographs the periphery of the vehicle. Then, if the acquired position of the vehicle belongs to an area where predetermined privacy processing is to be performed on an object included in the acquired captured image, the control unit stores, in a nonvolatile memory, data that is the captured image to which the privacy processing is applied, and if the acquired position of the vehicle does not belong to the area where the predetermined privacy processing is to be performed on the object included in the acquired captured image, the control unit stores the captured image in the nonvolatile memory.

A studio display environment and/or applications thereof are provided, wherein a display (e.g. LED display) is used onto which images or video are being shown, that are recorded by one or more cameras. The invention further relates to methods and systems for improved camera view in such studio display environment and/or applications.

Systems and methods for vision test and uses thereof are disclosed. A method may be implemented on a mobile device having at least a processor, a camera and a display screen. The method may include capturing at least one image of a user using the camera of the mobile device; interactively guiding the user to a predetermined distance from the display screen of the mobile device based on the at least one image; presenting material on the display screen upon a determination that the user is at the predetermined distance from the display screen; and receiving input from the user in response to the material presented on the display screen. The material presented on the display screen may be for assessing at least one characteristic of the user's vision. Mobile devices and non-transitory machine-readable mediums having machine-executable instructions embodied thereon for assessing a user's vision also are disclosed.
