Abstract
An image-recognition assisting method includes the steps of using an examination instrument to generate an image having a split-image area formed thereon; setting a region-of-interest (ROI) around the split-image area of the generated image; performing a pixel luminance addition processing on the ROI, so that all pixels in the ROI have increased luminance contrast; and performing a contrast correction on the ROI having increased luminance contrast, so that the luminance contrast between the split-image area and the area surrounding the split-image area in the ROI is further increased. The image-recognition assisting method optimizes the image generated by the conventional ophthalmic examination instrument, such as a fundus camera, to increase the sharpness and the luminance contrast of the image output by the fundus camera, so that an examiner can easily recognize two offset rectangular image parts in the split-image area and align them with each other to focus the examination instrument.
