The present disclosure relates to an image processing method and apparatus, an electronic device and a readable storage medium. The method comprises: traversing a plurality of multimedia materials, and according to a target color display standard, determining a multimedia material of a non-target color display standard included in the plurality of multimedia materials; converting the multimedia material of the non-target color display standard into a multimedia material of the target color display standard; and performing image rendering on the plurality of multimedia materials according to the target color display standard, so as to display the plurality of multimedia materials according to the image rendering result or export the plurality of multimedia materials as a video file in a specific format according to the image rendering result.

Embodiments described herein provide systems and methods for managing quality level of video transmission and storage. In a particular embodiment, a method provides receiving a video at a received quality level in a video storage system and determining a characteristic of the video. The method further provides determining whether the characteristic satisfies a criteria and, if the characteristic satisfies the criteria, storing the video at a quality level associated with the criteria.

The present invention discloses an interactive method on intelligent home appliance based on smart TV video scenes and the system thereof, the method includes: presetting a database to store a plurality of image features on different video scenes and an operation data on intelligent home appliance corresponding to different video scene types; obtaining a plurality of video data currently playing on the smart TV, and determining the current video scene type; based on the current video scene type, starting connection with the intelligent home appliances, and checking whether the connection between the smart TV and the intelligent home appliance is success or not; if the connection between the smart TV and the intelligent home appliance is detected to be successful, then the intelligent home appliances are controlled to perform the corresponding operations. The present invention may analyze the scene elements of the video contents playing on TV, and control various intelligent home appliances to automatically change the surrounding environment conditions of the user, thus may make the user immersive, and improve the interaction between the smart TV and intelligent home appliances, which has facilitated a user to watch a video.

Disclosed herein is a semiconductor integrated circuit which controls the quality of an image and includes a viewer detector, a region specifier, and a controller. The viewer detector detects the number of viewer(s) watching the image and a gaze region being watched by the viewer within the image. If the number of viewers is plural, the region specifier specifies a local region of the image as a target region based on a plurality of gaze regions being watched by the viewers. The controller performs image quality control on the target region.

There is provided a method for pre-processing a video stream for subsequent motion detection processing. The method comprises receiving a video stream of images, wherein each image in the video stream is represented by a first plurality of bits; enhancing the video stream of images by, for each image in the video stream: comparing the image to at least one previous image in the video stream so as to identify pixels where the image differs from the at least one previous image in the video stream, enhancing the image in those pixels where the image differs from the at least one previous image in the video stream; and converting the enhanced video stream of images so as to produce a converted video stream of images for subsequent motion detection processing, wherein each image in the converted video stream is represented by a second plurality of bits being lower than the first plurality of bits.

The present disclosure relates to an image processing method and apparatus, an electronic device and a readable storage medium. The method comprises: traversing a plurality of multimedia materials, and according to a target color display standard, determining a multimedia material of a non-target color display standard included in the plurality of multimedia materials; converting the multimedia material of the non-target color display standard into a multimedia material of the target color display standard; and performing image rendering on the plurality of multimedia materials according to the target color display standard, so as to display the plurality of multimedia materials according to the image rendering result or export the plurality of multimedia materials as a video file in a specific format according to the image rendering result.

Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device of an embodiment of the present disclosure includes: a quality calculator configured to calculate a source quality of an image signal received from an external settop box or a network; an image quality setter configured to set an image quality of the image signal based on the calculated source quality; and an image quality processor configured to perform image quality processing on the image signal based on the set image quality, wherein in response to the source quality of the received image signal being changed at a first time point, the image quality setter changes an image quality setting sequentially from a first setting to a second setting; and based on the image quality setting, the image quality processor performs image quality processing. Accordingly, flicker may be reduced when an image quality is changed due to a change in the source quality of the received image signal.

An image data transceiving system, comprising: a transmitting device, configured to output a first target image stream, wherein the first target image stream comprises a plurality of first target images; and a receiving device, configured to decode the first target image stream to obtain a plurality of second target images. The transmitting device or the receiving device generates a reference image stream according to the first target image stream. The reference image stream comprises first reference images generated by the transmitting device or second reference images generated by the receiving device. Data amount of the first reference images is less than data amount of corresponding ones of the first target images, and data amount of the second reference images is less than data amount of corresponding ones of the corresponding second target images. The transmitting device further receives the reference image stream through the receiving device.
