There are provided an image processing apparatus and an image processing method which are capable of correctly determining the scaling factor of an input image containing a specific image composed of a predetermined number of partial images. The wind dam is comprised of two longitudinally opposed sections each section having an outer shell and an inner inflatable bladder, constructed so that the outer shell houses the inner inflatable bladder. spermatozoa, such as the translation speed and the rotational speed of particles. The pin is disposed through both the first insertion hole and the second insertion hole to fix the shaft to the casing relatively. The active layer includes first and second well layers made of a nitride compound semiconductor containing In, where the second well layer emits light having a main peak wavelength which is longer than that of the first well layer, and where the growth number of the first well layer is more than the growth number of the second well layer. This organization structure is also conducive for extracting a portion of the database relevant to a particular purpose and replicating that portion elsewhere, such as on a palmtop computer, personal data apparatus, etc.
