Image recognition system and information-display method thereof

An image recognition system, comprising:

• a transparent display;
• an image capturing unit, configured to capture a background image of the transparent display;
• and
• a computation unit, configured to recognize a target object from the background image of the transparent display and retrieve one or more candidate background image sub-areas around the target object,
• wherein the computation unit further processes the one or more candidate background image sub-areas and generates one or more pieces of candidate display information corresponding to each candidate background image sub-area,
• wherein the computation unit further calculates the color ranking score of each piece of candidate display information on each candidate background image sub-area, and determines display information and a corresponding background image sub-area from the one or more pieces of candidate display information and the one or more candidate background image sub-areas, respectively,
• wherein the computation unit further determines whether the color ranking score of the display information satisfies a predetermined condition,
• if the color ranking score satisfies the predetermined condition, the computation unit directly displays the display information on the background image sub-area of the transparent display;
• if the color ranking score does not satisfy the predetermined condition, the computation unit adds a color feature on the display information and displaying the display information and the color feature on the background image sub-area of the transparent display.
