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

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.

An obstacle detection apparatus according to an embodiment includes an on-vehicle camera (image capturing unit), an estimation unit, and a determination unit. The on-vehicle camera is provided on a vehicle and captures an image of surroundings of the vehicle. The estimation unit estimates an existence region with an obstacle existing therein in an image captured by the image capturing unit. The determination unit determines presence or absence of the obstacle based on brightness of the existence region.

A lane departure warning apparatus that issues a warning for a lane departure of a vehicle monitors a change amount of a location of the vehicle relative to a division line that defines a travelling lane, in a case where the lane departure warning apparatus has detected the lane departure of the vehicle from the travelling lane. The lane departure warning apparatus is issues the warning to an output device in at least one of cases in which (i) the change amount monitoring part determines that the change amount of the location of the vehicle is equal to or greater than a first threshold value and (ii) the change amount monitoring part determines that the change amount per a unit of time is equal to or greater than a second threshold value.

Lane departure warning apparatus

An electronic control device according to an embodiment of the present invention includes an arithmetic device such as a microcomputer having a watchdog timer circuit, and a runaway monitoring circuit which monitors the arithmetic device for an operational failure by receiving a pulse output from the arithmetic device, in which the watchdog timer circuit or the runaway monitoring circuit detects occurrence of a failure of the arithmetic device according to the state (high level or low level) of an indication signal (wakeup signal) which shows the operational state of the arithmetic device.

A communication conversion apparatus achieve efficient conversion without conversion delay and converts messages that effect communication with different communication protocols and schedules. In a message conversion apparatus that performs message conversion of different communication protocols, a routing circuit and a scheduler circuits that perform scheduling of the different communication protocols are separately provided. And time-triggered scheduling and event-triggered scheduling are separately performed. Conversion of FlexRay and CAN messages can be efficiently implemented.

Communication message conversion apparatus and communication message conversion method

There is provided a gateway apparatus that controls a forwarding process of frame data between multiple communication channels, said gateway apparatus including a search engine that is respectively provided for each of the multiple communication channels to route the frame data between the multiple communication channels, and a first storage portion that is respectively provided for each of the multiple communication channels to temporarily stores the frame data routed.

Gateway apparatus and routing method

An apparatus for preventing corrosion of a contact includes a detection conducting path connected to the contact, a variable impedance unit and a comparing and switching unit. The variable impedance unit is connected to the detection conducting path. The variable impedance unit is switchable between (i) a first impedance used for passing a corrosion prevention current into the detection conducting path and (ii) a second impedance through used for passing a current, which is used for detecting a connection state of the contact, into the detection conducting path. The first impedance is lower than the second impedance. The comparing and switching unit compares a detected value with a corrosion threshold, compares the detected value with a restoration threshold and switches the variable impedance unit based on comparing results.
