Abstract: An image processing apparatus by which an excellent image can be obtained even after compression and expansion. A compression circuit (12) has a line scanning unit which divides original image data into color data groups in relation to respective pixels, a line compression unit (24) which expresses the value (y) of the color data corresponding to each pixel position in a predetermined section with a polynomial: y=ax3+bx2+cx+d wherein (x) denotes the pixel position which is a variable and a coefficient calculation unit (26) which obtains the color data values corresponding to the respective pixel positions in accordance with the received coefficients and pixel positions. The restored image data are outputted to a display apparatus, etc.

Abstract: A miniature vehicle action toy having an external rotating action element. The toy is inertially powered by an internal flywheel mounted on a drive shaft in the toy which is mechanically connected to the wheels to rotate therewith. The external action element is mounted on the drive shaft extremity outside of the toy body and rotates with the drive shaft to permit interesting and amusing play action of the toy. After the flywheel has been inertially energized, the toy can be balanced on the rotating action element and spun like a top.
