An information presentation apparatus for a vehicle includes an indicator mounted on the vehicle for indicating a target direction and a control unit for controlling the indicator. The control unit includes a function for acquiring a current position of the vehicle and a reference direction of the vehicle, a function for specifying a target and acquiring a target position, a function for calculating a target angle that indicates a target direction against the reference direction based on the target position, the current position and the reference direction, and a function for generating a presentation command based on the calculated target angle so as to indicate the target direction by the indicator. According to the apparatus, information for specifying the target position can be provided.

An fuel injection valve has: a needle housed in a valve body in a reciprocable manner; an injection hole plate attached to a front end portion of the valve body, the plate having an injection hole connecting an inside and an outside of the valve body; and a valve sheet which the needle is attached to or detached from so as to close or open a fuel flow path that reaches the injection hole of the injection hole plate through an outer circumference of the needle. The injection hole plate has a recessed portion dented in an axial direction of the needle so as to cause fuel flowing toward the injection hole through the valve sheet to descend lower than a height of an inlet port of the injection hole and then, to turn to ascension so as to reach the inlet port of the injection hole on the injection hole plate.

For facilitating detecting the position of additional information embedded in image information shown on a printed matter, an input unit configured to input image information and an embedding unit configured to embed a plurality of code patterns in the image information according to additional information are provided. The additional information includes direction-determination information used to detect the direction in which the additional information is embedded in the image information. When one of the code patterns is rotated, the rotated code pattern corresponds to one of the code patterns that are not yet rotated.

An image processing apparatus for applying a color balance correction to input image data, comprises a holding unit which holds information indicating a locus of a change in highlight color when a color temperature for image data is changed on a color space; a highlight color calculation unit which calculates a highlight color from the image data; a distance calculation unit which calculates a distance between the highlight color and the highlight color locus held in the holding unit on the color space; a reliability calculation unit which calculates a reliability for a value of the highlight color calculated by the highlight color calculation unit in accordance with the distance calculated by the distance calculation unit; and a color balance correction unit which applies the color balance correction to the image data using the highlight color and the reliability.
摘要:
A feature amount is calculated from input image data, then a scene of the input image data is determined based on the feature amount and the reliability of the scene is calculated. Then correction processing is performed on the input image data that corresponds to the determined scene and the scene reliability of the scene.
