Image processing system, information processing device, information storage device, and image processing method
An image processing system includes an image acquisition section that consecutively acquires still images, a direction determination section that determines a camera moving direction, a slit image generation section that generates slit images based on the consecutively acquired still images, and a panoramic image generation section that performs a synthesis process of the slit images to generate a panoramic image. The direction determination section determines whether the camera moving direction is a first camera moving direction or a second camera moving direction when the imaging section is moved during capture. The panoramic image generation section performs the synthesis process of each slit image based on the camera moving direction when the consecutively acquired still images were captured to generate the panoramic image.
1. An image processing system comprising:
a processor comprising hardware, wherein the processor is configured to:
acquire a plurality of still images captured by an image sensor, wherein a first still image of the plurality of still images is captured as the image sensor is moved in a first moving direction, and a second still image of the plurality of still images is captured as the image sensor is moved in a second moving direction different from the first moving direction;
extract a first silt image from the first still image, wherein the first slit image has a long side along a first slit direction;
extract a second slit image from the second still image, wherein the second slit image has a long side along a second slit direction;
extract a positioning slit from one of the plurality of still images, wherein the positioning slit has a long side along a third slit direction different from the first slit direction and the second slit direction;
determine a first overlapping area between the first slit image and the positioning slit;
determine a second overlapping area between the second slit image and the positioning slit;
determine a third overlapping area between the first overlapping area and the second overlapping area; and
generate a panoramic image based on the first slit image and the second slit image for which the third overlapping area has been determined.
2. A computer-readable storage device with an executable program stored thereon, wherein the program instructs a computer to perform steps of:
acquiring a plurality of still images captured by an image sensor, wherein a first still image of the plurality of still images is captured as the image sensor is moved in a first moving direction, and a second still image of the plurality of still images is captured as the image sensor is moved in a second moving direction different from the first moving direction;
extracting a first silt image from the first still image, wherein the first slit image has a long side along a first slit direction;
extracting a second slit image from the second still image, wherein the second slit image has a long side along a second slit direction;
extracting a positioning slit from one of the plurality of still images, wherein the positioning slit has a long side along a third slit direction different from the first slit direction and the second slit direction;
