    摘要: A motion detection apparatuses and method where a characteristic region is extracted from an image produced by an imaging device are described. A modified region is formed by modifying the characteristic region. Voting occurs so as to count up to increase a count value at a memory address corresponding to a location inside the modified region and to reset a count value at a memory address corresponding to a location outside the modified region. At least one of the moving direction and the moving speed of the modified region is calculated based on a difference among accumulated count values for adjacent locations. The position of the modified region can be calculated based on count values and locations in the modified region.

    摘要: A process for producing a supported catalyst for the synthesis of methacrolein and methacrylic acid in which a catalytic active substance comprising a composite oxide containing molybdenum and bismuth as essential components is supported on the inside surface and/or the outside surface of an inert carrier, which comprises the steps of drying a mixed solution or an aqueous slurry containing the compounds of the elements constituting the catalytic active substance, subjecting the dried product to a primary calcination at a temperature in a range of 200.degree.-400.degree. C. to form a catalytic active substance precursor, comminuting the obtained catalytic active substance precursor to such an extent that the medium particle size in the volume-based particle size distribution becomes 10 .mu.m or less, supporting the comminution product on an inert carrier, and subjecting it to a secondary calcination at a temperature which is 100.degree. C. or more higher than the primary calcination temperature.
