    • A first and a second image (401 and 501) containing a shared region of interest (400) are captured (201 and 202) using a rolling shutter mode of image capture. These two images are captured at different times, such that the second image follows the first image by a given amount of time. A corrected image is then formed (203) of the region of interest by modifying at least one of the first and second images as a function, at least in part, of the given amount of time that separates capture of the two images along with pixel capture delay times as correspond to the rolling shutter mode of image capture (the latter referring, by approach, to pixel row capture delay times as characterize the rolling shutter image capture process itself)
    • 使用图像捕获的滚动快门模式捕获包含共享感兴趣区域(400)的第一和第二图像(401和501)(201和202)。 这两个图像在不同的时间被捕获,使得第二图像在给定的时间量之后跟随第一个图像。 然后,通过修改第一和第二图像中的至少一个作为功能,至少部分地在给定的时间量上分离两个图像的捕获以及像素的功能,形成校正图像(203) 拍摄延迟时间对应于图像拍摄的滚动快门模式(后者通过接近方式参考作为滚动快门图像拍摄过程本身的特征的像素行捕获延迟时间)

    • An electronic device (1100) and a method for character segmentation (100) includes an image analyzer (1110) that generates individual character images. The image analyzer binarizes (115) a gray scale image (200) of a horizontal row of characters by using a general threshold method to generate a first image (300). The image analyzer also binarizes (120) the gray scale image using an edge detection method to generate a second image (405). The image analyzer determines (125) a character row region (425) of the second image by using horizontal projection analysis. The image analyzer isolates (130) the character row region of the first image using the character row region of the second image. The image analyzer uses the character row region to generate (135) individual character images. The electronic device may include an image capture device (1105) and a character recognition program (1115).
    • 一种电子设备(1100)和一种用于字符分割(100)的方法包括产生单个字符图像的图像分析器(1110)。 图像分析器通过使用通用阈值方法来二值化(115)水平行字符的灰度图像(200)以生成第一图像(300)。 图像分析器还使用边缘检测方法二值化(120)灰度图像以生成第二图像(405)。 图像分析器通过使用水平投影分析来确定(125)第二图像的字符行区域(425)。 图像分析器使用第二图像的字符行区域隔离(130)第一图像的字符行区域。 图像分析仪使用字符行区域来生成(135)个别字符图像。 电子设备可以包括图像捕获设备(1105)和字符识别程序(1115)。
