    • A CPU includes: an original image recording function for recording a still image or a recorded image as an original image; a contrast correction function for performing contrast correction on a still image or a recorded image; a coordinate calculation function for calculating pixel coordinates on an original image which correspond to pixel coordinates designated on a contrast corrected image; a stereo measurement function for performing stereo measurement using pixel coordinates of an original image calculated by the coordinate calculation function; a measurement result reflection function for reflecting on a contrast corrected image a measurement result of stereo measurement performed by the stereo measurement function; and a dynamic range expansion function for enhancing brightness of an image area which is darker than a predetermined threshold. These functions enable stereo measurement to be performed precisely using an image on which image processing has been performed.
    • CPU包括:用于将静止图像或记录图像记录为原始图像的原始图像记录功能; 用于对静止图像或记录图像执行对比度校正的对比度校正功能; 坐标计算功能,用于计算对应于在对比度校正图像上指定的像素坐标的原始图像上的像素坐标; 立体测量功能,用于使用由所述坐标计算功能计算的原始图像的像素坐标来执行立体测量; 测量结果反射功能,用于在对比度校正图像上反映由立体测量功能执行的立体测量的测量结果; 以及用于增强比预定阈值更暗的图像区域的亮度的动态范围扩展功能。 这些功能可以使用执行了图像处理的图像精确地执行立体声测量。
