Image processing apparatus, image processing method, and program

Abstract

An image processing apparatus includes an image capturing section, a marker-image defecting section, a judging section and an output section. The image capturing section captures at least a part of a target image, which includes a plurality of marker images and a recognition target range defined by the plurality of marker images, to acquire a captured image. The marker-image detecting section detects the marker images from the captured image. The judging section judges based on a detection result, whether or not the recognition target range is included in the captured image. When the judging section judges that the recognition target range is not included in the captured image, the output section outputs guidance for capturing the recognition target range.

Claims

1. An image processing apparatus comprising: an image capturing section that captures at least a part of a target image, which includes a plurality of marker images and a recognition target range defined by the plurality of marker images, to acquire a captured image;a marker-image detecting section that detects the marker images from the captured image;a judging section that judges based on a detection result, whether or not the recognition target range is included in the captured image; andan output section that, when the judging section judges that the recognition target range is not included in the captured image, outputs guidance for capturing the recognition target range.

2. The image processing apparatus according to claim 1, wherein when the marker-image detecting section does not detect the marker image, the output guidance includes information on a focus of the capturing, a capturing size or a capturing place.

3. The image processing apparatus according to claim 1, wherein when number of the detected marker image is not equal to a predetermined number and a size of the detected marker image is not within a predetermined range, the output guidance includes information on at least one of a capturing size and a magnification of the capturing.

4. The image processing apparatus according to claim 1, wherein when number of the detected marker image is not equal to a predetermined number and a size of the detected marker image is within a predetermined range, the output guidance includes information on capturing place.

5. The image processing apparatus according to claim 1, wherein: when number of the detected marker image is equal to a predetermined number, the judgment section further judges at least one of:whether or not a size of the recognition target range is within a predetermined range,whether a brightness of the captured image satisfies a predetermined condition,whether the captured image is in focus, andwhether the detected recognition target range is not distorted, andthe output section outputs the guidance based on a result of the judgment.

6. An image processing apparatus comprising: an image capturing section that captures at least a part of a target image, which includes a marker-image set made up of plural kinds of marker images and a recognition target range defined by the marker-image set, to acquire a captured image;a marker-image detecting section that detects at least a part of the marker images included in the marker-image set, from the captured image;a position estimating section that estimates a position of the recognition target range in the captured image based on at least one of number of the detected marker image and a kind of the detected marker image; andan output section that outputs guidance for capturing the recognition target range, based on the estimated position of the recognition target range.

7.
