Image-capturing apparatus, captured image processing system, and recording medium

摘要

A mobile terminal apparatus includes a geometrical arrangement detecting section (111) detecting groups of edge pixels arranged in a shape of a line segment in an image captured by an image-capturing apparatus; and a display processing section (112) causes a contour line representative of a contour of a rectangular captured object to be displayed on the captured image displayed on a display section so that the contour line is superimposed on the groups of edge pixels detected by the geometrical arrangement detecting section (111).

主权项

1. An image-capturing apparatus, comprising:
a sensor capturing an image of an object which is rectangular; a display displaying a captured image, which is an image captured by the sensor; and a processor configured to:
determine, as an output target image, the captured image displayed on the display at a designated timing;detect four groups of edge pixels arranged in a shape of a line segment on the image captured by the sensor; and cause the display to display first missing information indicating that one corner of the object is outside an image area captured by the sensor, in a case where three of vertexes of a quadrangle surrounded by straight lines corresponding to respective four line segments represented by the detected four groups of edge pixels are within the captured image area and a remaining one of the vertexes of the quadrangle is outside the captured image area.
