摘要： An object recognition apparatus includes an image input unit capturing image data, an object dictionary unit storing conditions to specify a type of an object, and a processor collating the image data with the conditions and specifying the type of the object imaged in the image data, in which the object dictionary unit classifies the conditions into hierarchies and stores the classified conditions, and the processor performs collation while narrowing down object conditions positioned in lower hierarchies based on a collation result of object conditions positioned in upper hierarchies.

摘要： A recursive noise reduction device which reduces the noise component(s) of stationary region(s) in a moving image, successively cyclically calculating the coefficient (K) times of the present image signals and (1-K) times of the previous image signal having a correlation with the present image signal. The present image signal is a signal of an image of a frame or field that is presently entered and the previous image signal is a signal of an immediately previous image of the frame or field. The recursive noise reduction device includes a calculating unit to recursively calculate a sum of the coefficient K times the present image signal and (1-K) times the previous image signal, modifying the value of the aforementioned coefficient K according to the number of times of cyclic calculation, and a movement detection unit to detect the movement of an image within the stationary region(s) of the image. The value of the coefficient K is modified according to the output signal of the movement detection unit. Preferably, in the case that movement is detected by the movement detection unit, the value of the coefficient K is made equal to 1 as regards only the movement region of the image, and after this, the value of K is gradually made smaller.
