Image generation device and image generation method

An image processing device according to an aspect of the embodiment includes a display controller and a determining unit. The display controller generates a synthesized image when viewing a perimeter of a vehicle from a virtual viewpoint based on an image from an image capturing device and causes a display unit to display the synthesized image. The determining unit determines, in a case where a screen other than a virtual viewpoint screen including the synthesized image is displayed on the display unit, whether a switching condition to a notification screen for notifying an occupant of presence of an obstacle is satisfied when the obstacle is detected by a detector. The display controller causes the display unit to display the notification screen obtained by superimposing a predetermined notification image on the virtual viewpoint screen, when the determining unit determines that the switching condition is satisfied.

An image processing device according to an embodiment includes an image acquisition unit, an information acquisition unit, a generation unit, a composition unit, a determination unit, and a display control unit. The image acquisition unit acquires a captured image where an image of an environment of a vehicle is captured by an image-capturing device. The information acquisition unit acquires positional information regarding a detected position of an obstacle that exists in an environment of the vehicle. The generation unit generates a virtual viewpoint image where an environment of the vehicle is viewed from a virtual viewpoint, based on the captured image. The composition unit composites a notification image that provides notification of existence of the obstacle at the detected position with the virtual viewpoint image. The display control unit controls a display format of the notification image that is composited with the virtual viewpoint image, based on the positional information.

An image processing device according to an embodiment includes a display control unit, a pattern specification unit, and a pattern collating unit. The display control unit generates a composite image that is a surrounding image of a vehicle viewed from a virtual viewpoint, based on images input from in-vehicle cameras, and displays thereof on a display unit. The pattern specification unit specifies an image pattern to be output as the input image among image patterns, for each in-vehicle camera. The pattern collating unit determines whether all image pattern responses from the in-vehicle cameras match with the image pattern. The display control unit displays a certain preparation image on the display unit when the display switching condition to the composite image is satisfied, and displays the composite image thereon instead of the preparation image, when the pattern collating unit determines that all the image pattern responses match with the image pattern.

An image acquisition part acquires a plurality of shot images captured by a plurality of cameras disposed on a vehicle, each of the plurality of shot images showing a periphery of the vehicle. An image composer projects data of the plurality of shot images onto a virtual projection surface corresponding to the periphery of the vehicle, and generates a composite image showing the periphery of the vehicle viewed from a virtual viewpoint, using the data projected onto the virtual projection surface. The image composer uses, as the virtual projection surface, a special virtual projection surface that includes a curved area having an upward convex curve. The curved area includes an area where a distance from a location of the vehicle is relatively short and a slope is relatively high, and another area where the distance from the location of the vehicle is relatively long and the slope is relatively low.

A fuel-saving driving diagnostic device stores an external power amount which indicates an amount of power charged by an external device and an internal power amount which indicates an amount of power charged by vehicle driving. The fuel-saving driving diagnostic device calculates a driving power amount which indicates an amount of power required for vehicle driving based on the stored external power amount, stored internal power amount, and an amount of power a vehicle currently has, and makes a diagnosis of fuel-saving driving based on the calculated driving power amount and the stored external power amount. As a result, sufficient information is calculated for prompting the driver of a plug-in hybrid car to do the fuel-saving driving.

Fuel-saving rating device and power amount management device

A vehicle power indication status quantity display unit displays on an indicator a vehicle power indication status quantity obtained by dividing the torque required for driving a hybrid vehicle by the upper limit value of the torque that does not excessively increase the fuel consumption. A HV eco zone of the vehicle power indication status quantity display unit is the zone that is determined by the upper limit value and the lower limit value of the HV eco zone that indicates the motor is being effectively used to drive the vehicle. A check is made to determine whether the vehicle power indication status quantity is within the HV eco zone, and, if it is determined to be within the HV eco zone, the driving being performed is diagnosed as fuel-saving driving.

An accelerator opening determining unit determines whether an accelerator opening achieved through an accelerator operation by a driver of a vehicle exceeds an upper limit value thereof. A travel distance adding-up unit adds up a travel distance within accelerator-opening upper limit value when the accelerator opening is not determined to exceed the upper limit value. When the accelerator opening is determined to exceed the upper limit value, the travel distance adding-up unit adds up a travel distance exceeding accelerator-opening upper limit value. A fuel-saving driving rating unit rates the driving of the driver based on each added-up value added up by the travel distance adding-up unit.

A shift lever position determining unit determines whether a shift lever position of a vehicle satisfies predetermined conditions. If the shift lever position is determined to satisfy the predetermined conditions, a travel distance adding-up unit adds up an optimum shift lever position travel distance. If the shift lever position is determined not to satisfy the predetermined conditions, the travel distance adding-up unit adds up an inappropriate shift lever position travel distance. A fuel-saving driving rating unit rates driving by a driver based on each added-up value added up by the travel distance adding-up unit. A fuel-saving driving advice generating unit notifies the driver of fuel-saving driving advice together with a rating result in accordance with the rating result. Therefore, it is possible to encourage the driver to select an optimum shift lever position with high fuel efficiency and thereby to improve the driver's knowledge and awareness of the fuel-saving driving.

An accelerator-off, fuel-cut traveling determining unit determines whether the number of engine revolutions of a vehicle is equal to or higher than a predetermined value, whether an accelerator opening rate is equal to or lower than a predetermined value, and whether a traveling state is an accelerator-off, fuel-cut traveling state where a quantity of fuel injection to an engine is 0. When it is determined that the traveling state is the accelerator-off, fuel-cut traveling state, the traveling distance adding-up unit adds up accelerator-off, fuel-cut traveling distances. A fuel-saving driving rating unit rates driving by a driver based on each of the added-up values which were added up by the traveling distance adding-up unit. A fuel-saving driving advice generating unit notifies the driver of a fuel-saving driving advice together with a rating result in accordance with the rating result. Therefore, it is possible to encourage the driver to perform early engine operation by an engine braking, and to enhance the driver's awareness of fuel saving driving.

A total distance calculating unit calculates a total running distance and an energy-cut-off distance calculating unit calculates a deceleration running distance of a vehicle. The deceleration running distance is a distance for which the vehicle runs while the vehicle is in a deacceleration state and no energy is supplied to a motor of the vehicle. A deceleration-running evaluating unit evaluates deceleration running of the vehicle based on a ratio of the deceleration running distance to the total running distance. The result of the evaluation is displayed for the driver of the vehicle.
