An operation method performed by an image processor is provided, including the following operations of receiving a mixed image including an input image and a first on-screen-display (OSD) pattern and generating a second OSD pattern, different from the first OSD pattern, based on the mixed image. The second OSD pattern encompasses protection regions of the input image, and the protection regions are in close proximity of the first OSD pattern. The method further includes operations of performing image processing to remaining regions, different from the protection regions, of the input image and generating an output image. The output image includes the second OSD pattern and the remaining regions of the input image, being performed by the image processing.

A device and method for blending image data and the alpha channel and reconstructing to obtain the image again after transmission. An encoder blends the alpha channel and the red-green-blue (RGB) image data through a layer blending method that is supported by the general application processor (AP). Transporter image data, such as a checkerboard pattern, is blended with 1-alpha channel data to obtain a transporter. The blended image data (RGB+alpha) is mixed with the transporter to obtain mixed image data. The mixed image data is then transmitted through the existing transmission interface. After receiving the mixed image data, reconstruction processing is performed by a decoder to obtain the original RGB image data and the alpha channel again.

Method of layer blending and reconstruction based on the alpha channel

A method for generating a plurality of on-screen display (OSD) data is used in a back-end (BE) circuit. The BE circuit is configured to process a plurality of image data to be displayed on a display device. The method includes steps of: receiving the plurality of image data from an application processor (AP); and extracting information of a detecting layer embedded in the plurality of image data, wherein the information of the detecting layer indicates the plurality of OSD data corresponding to at least one user-interface (UI) layer in the plurality of image data.

Method of generating OSD data

The disclosure proposes a method and a system for 360-degree video playback. The method is applicable to a video playback system and includes at least the following steps. A current frame of a 360-degree video having a sequence of frames is received. Candidate objects in the current frame are detected, and a main object is selected from the candidate objects by using a selector recurrent neural network (RNN) model based on information of the candidate objects in the current frame. A viewing angle corresponding to the current frame is computed by using a regressor RNN model based on the main object in the current frame. The current frame is displayed on the screen according to the viewing angle.

The present invention relates to a method for treating spent tin or tin/lead stripping solution used in the electronic industry, particularly in the manufacture of printed circuit boards or a lead frames. Said method comprises (i) electrolytically reducing copper ions in the solution to copper at a low temperature; (ii) electrolytically oxidizing Sn and Pb in the solution at a high temperature to form solid tin and lead oxides and hydroxides; (iii) separating solid tin and lead oxides and hydroxides from the solution; (iv) dissolving tin and lead oxides and hydroxides obtained in step (iii) in a strong alkali or acidic solution; and (v) electrolytically reducing the alkali or acidic solution obtained in step (iv) at a high temperature to recover metallic tin and lead. Also, the filtrate obtained in step (iii) above is useful for preparing fresh tin or tin/lead stripping solution.
