Abstract: A boat control system includes an imager to image a user towed by a hull, an image processor to determine a predetermined state of the user from an image captured by the imager, and a controller configured or programmed to perform a control to adjust a thruster operable to change a propulsion state of the hull based on the predetermined state of the user determined by the image processor to change the propulsion state of the hull.

Abstract: A marine vessel display device includes an imager that images surroundings of a vessel body, an image processor that generates a bird's-eye view image based on images captured by the imager, a display provided in the vessel body and that displays the bird's-eye view image, and a controller. The controller is configured or programmed to perform a control to switch an image displayed on the display from the bird's-eye view image to an object image obtained by imaging in a direction toward an object from the vessel body based on object information.

Abstract: An imaging device that reduces differences between a bird's eye image and an actually measured distance includes imaging cameras mounted on a ship to capture peripheral images of the ship and combines the peripheral images captured by the imaging cameras to create the bird's eye image as a composite image. The imaging device includes an auxiliary camera adjacent to at least one of the imaging cameras, and a distance calculator that calculates a distance in a lateral direction using the auxiliary camera and the at least one of the imaging cameras adjacent to the auxiliary camera.

Abstract: An imaging system for a ship includes cameras mounted on the ship and spaced apart at a predetermined interval, and a controller that combines peripheral images of the ship captured by the respective cameras to create a simulated bird's eye image. Adjacent ones of the cameras are located at positions and angles so that the peripheral images include a common portion of the ship. The controller performs a calibration process to adjust areas of the peripheral images to be used for the bird's eye image based on a calibration index located at a portion of the ship and included in the common peripheral images.

Abstract: A marine vessel includes a hull including a cabin, an imager that images a field-of-view shielded region, which is a region in which a marine vessel operator's field of view is obstructed when the marine vessel operator located on an operation seat provided inside the cabin looks around an outside of the marine vessel in a horizontal direction, and a display provided at a position visible from the operation seat and that displays a field-of-view complement image, which is an image of the field-of-view shielded region captured by the imager.

Abstract: A distortion correction portion includes a distortion calculation portion which calculates a distortion based on a movement of an image sensing apparatus in the image sensing operation, a distortion adjustment value calculation portion which calculates a distortion adjustment value based on a generation situation of an input image, and a distortion correction processing portion which performs a distortion correction process for correcting the distortion in the input image based on the distortion and the distortion adjustment value. The distortion adjustment value calculation portion decreases the distortion adjustment value in accordance with a generation situation of the input image, so that the degree of the correction in the distortion correction process by the distortion correction processing portion is decreased.

Abstract: An image processing apparatus outputs an output image by synthesizing a first image obtained by shooting, a second image obtained by shooting with an exposure time longer than the exposure time of the first image, and a third image obtained by reducing noise in the first image. The image processing apparatus has a noise reduction processing control portion which controls the contents of image processing for obtaining the third image from the first image according to the noise level in the first image.

Abstract: An image sensing apparatus that includes an image sensing portion outputting the image data of an image by shooting and that generates an output image based on the output data of the image sensing portion obtained in response to a predetermined shooting command has: a first correction portion which, based on the image data of a first image shot by the image sensing portion and the image data of a second image shot by the image sensing portion with an exposure time longer than the exposure time of the first image, performs position adjustment between the first and second images and then synthesizes the first and second images to generate the output image; a second correction portion which generates the output image by reducing noise in the first image without using the second image; and a correction control portion which executes selection processing to alternatively select one of the first and second correction portions based on a shooting condition set for shooting of the second image or based on the output

Abstract: An image sensing apparatus senses first and second images, and produces a merged image by merging the first and second images together. An exposure time for the second image is longer than an exposure time for the first image. By sensing the first image before the second image, the first image is prevented from being sensed during a camera-shake-increase period starting a long time after the input of a image-sensing-start instruction. Also, by waiting for an image-sensing standby time to elapse before sensing the first image, the first image can be sensed during a period of a particularly small camera shake.

Abstract: A merged image is generated by merging together a first image obtained by shooting with a reduced exposure time, a second image obtained by shooting with an increased exposure time, and a third image obtained by filtering out a high-frequency component from the first image. Here, a merging ratio at which the second and third images are merged together is determined by use of differential values obtained from the second and third images. Also, a merging ratio at which the first image and the second and third images (a fourth image) are merged together is determined by use of edge intensity values obtained from an image based on the first image.

Abstract: Before performing a zoom in operation, a view angle candidate frame indicating an angle of view after the zoom in operation is superimposed on an input image to generate an output image. A user checks the view angle candidate frame in the output image so as to check in advance an angle of view after the zoom in operation.
