In a display-object information displaying apparatus, each display object predetermined as a detection target is detected from image data captured by a front capture apparatus to capture of the front of a vehicle. A recognition failure probability that the driver fails to recognize each display object is evaluated. A memory saves the recognition failure probability and display object data containing display-object information with respect to each display object. A display unit displays the display-object information based on the corresponding display object data saved in the memory with respect to each display object. The display-object information about the display object assigned the higher recognition failure probability is displayed preferentially among the display objects corresponding to the display object data saved in the memory.
