Claim One:
1. An image processing apparatus comprising: a projection unit configured to project, onto an object, a projection pattern as an image obtained by compositing a first two-dimensional pattern image and a second two-dimensional pattern image; a capturing unit configured to capture the object onto which the projection pattern has been projected; and a measurement unit configured to measure three-dimensional shape information of the object based on the projection pattern projected by said projection unit and an image captured by said capturing unit, wherein when a region formed from at least one pixel is set as a first unit area, and a region having a size larger than that of the first unit area is set as a second unit area, each first unit area of the first two-dimensional pattern image is assigned with one of a plurality of pixel values, and each second unit area of the second two-dimensional pattern image is assigned with one of the plurality of pixel values.
