摘要： An image processing circuit and a method thereof are provided herein. The image processing circuit has a first scaling circuit, a plurality of line buffers, a first sharpness circuit, a second scaling circuit, and a second sharpness circuit. The first scaling circuit enlarges an input image along a first direction to generate a first enlarged image. The line buffers temporarily store the pixel values of a plurality of pixel rows of the first enlarged image. The first sharpness circuit vertically sharpens the first enlarged image to generate a first sharpened image. The second scaling circuit enlarges the first sharpened image along a second direction to generate a second enlarged image. The second sharpness circuit horizontally sharpens the second enlarged image to generate a second sharpened image. Accordingly, it is possible to use the line buffers having shorter data lengths to perform the vertical sharpening.

摘要： A warning light includes a base to which an elongated post, formed by a plurality of tubular segments telescopically jointed, is fixed to support on the top end of the post a lamp unit. A battery set is placed inside the base to power the lamp unit with electrical wire extending through the post. A plurality of legs are provided to each extend through holes formed on the base. Each of the legs is constituted by a primary member and a secondary member pivoted together with the primary member extending out of the respective hole of the base and the secondary member movably received within the hole. The hole is provided with an inclined inside surface which define an expanded lower opening on the underside of the base so as to allow the primary member to extend from the base in an inclined, diverging manner to define an enlarged bottom area for more stably supporting the warning light. A solar panel system is disposed on the lamp unit and housed by a transparent dome to serve as a secondary power source. The lamp unit is also provided with a plurality of sideways extending lugs to engage and hold the secondary members of the legs when the post is telescoped so as to provide a compact, stowed configuration.
