Abstract

An image display apparatus for a shovel that includes a lower-part traveling body, an upper-part turning body turnably placed on the lower-part traveling body, and an attachment mounted on the upper-part turning body, and performs work in a work area by driving the attachment, includes an image display part configured to display the work area to be subjected to the work. An image of the work area captured with an image capturing device is subjected to image processing to add and indicate a distribution of depressions and elevations of the work area, and is displayed on the image display part.

Claims
