Abstract: A pattern generating apparatus includes a sequence generating unit and an image data generating unit. The sequence generating unit generates a sequence formed by terms having M-value numeric values. The image data generating unit generates the image data by converting each numeric value of the sequence into a gray-level value according to each numeric value, and the sequence is generated by the sequence generating unit. The sequence generating unit generates the sequence such that vectors expressed by sub-sequences have different directions for the sub-sequence constituting the generated sequence.

Abstract: It is intended to provide an image processing apparatus enabling an image processing for association of a standard image to a reference image using a reduced number of pixels without deteriorating accuracy for detecting a movement of a detection subject. A detection subject region setting unit obtains a picked-up image at a first time point as a standard image from time-series picked-up image data obtained by an image pickup unit and selects a plurality of correlation windows including an image region of the detection subject in the standard image with relative positions with respect to the standard point being identified.

Abstract: An apparatus, method, and program for measuring the three-dimensional shape of an object by analyzing an optical pattern projected onto the object includes a line sensor and an image analysis unit. The line sensor reads the target object, onto which the optical pattern is projected. The image analysis unit analyzes the optical pattern in the image read by the line sensor based on a spatial fringe analysis method, and the image analysis unit computes the three-dimensional shape information on the target object. The phase of a pixel included in an image taken of the optical pattern is determined based on the brightness values of the pixel and at least one neighboring pixel in the image; thus the height information of the object can be determined. In addition, the height of the target object at a given position can be computed based on how much the phase of the optical pattern projected onto a certain position of the object is shifted from a reference phase.

Abstract: Information necessary to control a vehicle is to be effectively detected in accordance with a situation. A supposition situation selecting section selects a supposition situation closest to the present situation of an own vehicle from a plurality of pre-supposed supposition situations on the basis of situation information acquired from a situation information acquiring unit and a supposition situation selection table through a situation information input I/F circuit. A detection process selecting portion selects a detection process to be actually performed from detection processes which can be performed by each detecting portion of a target detecting section on the basis of the selected supposition situation and a detection process selection table. The invention is applicable to an in-vehicle image processing device.
