A digital image acquisition system includes a portable apparatus for capturing digital images and a digital processing component for detecting, analyzing and informing the photographer regarding motion blur, and for reducing camera motion blur in an image captured by the apparatus. The use of an electro-catalyst formed from heteropoly acids immobilized by a conductive material, such as carbon or platinum black, and stabilizing a metallic black with the immobilized conductive material addressed these automotive fuel cell needs. Based on the genre information, a parameter determination section determines an acoustic processing parameter which is used for adjusting the tone of the output from a acoustic processing section.
