<p>A focus state display apparatus for a camera, comprising focus area extraction means (21) for extracting the image signals of a predetermined area from photographed image signals, edge enhancement processing means (22) for enhancing the edge of the extracted image signals, time integration value calculation means (25) for calculating an integration value of the edge-enhanced image signals in a certain period of time, focus state determination means (26) for determining the focus state of the photographed image signals on the basis of the calculated integration value, and focus state display means (31) for displaying the determined focus state. A user is capable of readily determining the focus state of the camera and confirming and adjusting the focus thereof with accuracy even in a display apparatus of a camera-equipped portable terminal device (10), where the size and resolution thereof are limited.</p> |
