Abstract: A method for generating masking image using general polygonal mask includes receiving a pixel of a raw image and a polygon vertices array corresponding to a polygonal mask, determining whether the pixel is inside the polygonal mask, labeling the pixel to be a masked pixel if the pixel is inside the polygonal mask, or labeling the pixel to be a visible pixel if the pixel is outside the polygonal mask, and outputting the masked pixel or the visible pixel to generate the masking image.
Abstract translation: 使用一般多边形掩模生成掩蔽图像的方法包括：接收与多边形掩模相对应的原始图像和多边形顶点阵列的像素，确定像素是否在多边形掩模内，如果像素为像素，则将像素标记为被掩模像素 在多边形掩模内部，或者如果像素在多边形掩模之外，则将像素标记为可见像素，并输出屏蔽像素或可见像素以产生掩蔽图像。

Abstract: An electronic device, a fingerprint sensing control method and a fingerprint scanning control method are provided. A sensing region of a display panel is divided into a plurality of fingerprint zones. The electronic device determines at least one target fingerprint zone from the fingerprint zones according to a touched area. The electronic device scans the at least one target fingerprint zone to control the at least one target fingerprint zone for performing fingerprint sensing. The electronic device performs an accelerated scanning operation. The accelerated scanning operation includes: setting a scanning speed corresponding to at least one target scanning group coupled to at least the touched area to a first speed; and setting a scanning speed corresponding to one or more scanning groups other than the at least one target scanning group to a second speed higher than the first speed.

Abstract: An electronic device and a fingerprint sensing control method thereof are provided. The electronic device includes a touch control circuit and a fingerprint sensing control circuit. The touch control circuit is coupled to the display panel. The touch control circuit performs touch detection on the display panel to obtain a finger press area corresponding to the finger on the display panel. The fingerprint sensing control circuit is coupled to the touch control circuit to obtain a finger press area. The fingerprint sensing control circuit is coupled to the display panel to perform a fingerprint sensing control on a display panel. The fingerprint sensing control circuit scans the finger press area on the display panel in a first direction during a first period and scans the finger press area in a second direction different from the first direction during a second period after the first period.
