An image processing apparatus includes a detector, an estimator and a determiner. The detector detects a candidate region of a captured image captured by a camera, the candidate region serving as a candidate for a water drop region affected by a water drop on the lens of the camera, based on an edge strength of each pixel in the captured image. The estimator estimates, based on the candidate region, a circle that includes the candidate region. The determiner determines whether or not the candidate region is part of the water drop region based on the edge strength of some of the pixels in the circle.

Image processing apparatus

An attachable matter detection apparatus according to an embodiment includes an acquirement unit, a creation unit, and a determination unit. The acquirement unit acquires a determination target area of an attachable matter from a photographic image. The creation unit creates histograms of at least an edge intensity, luminance, and saturation for the determination target area acquired by the acquirement unit. The determination unit determines whether or not the attachable matter exists in the determination target area on the basis of a ratio of frequency of each grade in each of the histograms created by the creation unit.

Attachable matter detection apparatus and attachable matter detection method

A water-droplet detecting apparatus according to an embodiment includes a setting unit, a first extraction unit, a second extraction unit, and a determination unit. The setting unit sets concentric circles having a center at arbitrary one point of a captured image of an image capturing unit. The first extraction unit extracts candidate pixels based on gradients of pixels on a circumference of each of the concentric circles. The candidate pixels are candidates for pixels that are estimated to indicate a water droplet adhered to the image capturing unit. The second extraction unit extracts one or more candidate circles based on the candidate pixels extracted by the first extraction unit. The one or more candidate circles are candidates for circles that indicate a shape of the water droplet. The determination unit determines whether or not the water droplet is adhered based on an extraction result of the second extraction unit.

Liquid-droplet detecting apparatus, liquid-droplet detecting method, and computer-readable recording medium

A communication device, particularly, a car-mounted information device, which makes it possible to obtain information of a transmitting source and of a receiving end linked to a navigation function relying upon end-to-end communication by using electronic mail among vehicles. The car-mounted information device comprises a cellular phone terminal connected to an external unit, a car navigation function, a modem function for transmitting and receiving data end to end between the vehicles via the cellular phone terminals, a mail transmitting/receiving function for transmitting and receiving the data using electronic mail, and a car navigation-linking function for processing the information of the electronic mail transmitted and received by linking the information to the car navigation function.

Car mounted information device

A display system able to display a television screen and a navigation screen, giving due consideration to safe vehicle operation, provided with a screen switching unit for displaying a television screen instead of a navigation screen at least at part of a display screen during display of the navigation screen, a switching instructing unit for instructing switching to the screen switching unit when detecting that a predetermined event has occurred, or a screen area setting unit for setting a specific area in the screen for display by switching by the screen switching unit instead of the switching instructing unit.
