摘要:
An image forming apparatus discriminates a color of an inputted color image for each pixel and generates a first color component and a second color component. The apparatus compares values of the first and the second color components, and selects and outputs the color component having a larger value. Meanwhile a color component which is not selected is diffused to neighboring pixels. When pixels neighboring a pixel of interest in a predetermined area are filled with one color component, the other color component is selected and outputted regardless of the values of the first and second color components.

When an original image of a full color is reconstructed by two colors, it is intended to prevent that a part of the original image is not reconstructed. An image of a full color original is read by a CCD, thereby forming signals of R, G and B. In an image processing unit, the R, G, and B signals are converted into red and black signals. The red and black signals are sent to a printer unit and an image is formed in red and black.

A helmet display for displaying information to a user thereof while the user is riding, for example, a motorcycle. A display mounted on a helmet includes a plurality of display elements horizontally aligned in a spaced relation along the curvature of the jaw of the helmet. A reflector reflects the images of the display elements into the eyes of a user wearing the helmet. The images of the display elements form as a whole information to the user. The reflector may be a reflective surface provided at a lower portion on the shield of the helmet. The reflector may be mounted on the upper portion of the jaw and the reflective surface thereof may have a curvature substantially the same as that of the jaw of the helmet.

A connecting pin has a body of great strength which will not come off position when locked and will not be caught on the way of insertion and removal.In the connecting pin, a flange 10 for locking is provided on the rear end of a column-like body. A long hole 11 is formed through in the shank part on the forward end side of the body. A shaft 12 is inserted in the shank part on the forward end side of the body in a direction intersecting the long hole and opposed two holes 17 are formed in parallel with this shaft. A lock piece 13 supported on the aforesaid shaft at a midway point and having a plurality of slots 16 in both sides is rotatably inserted and in the hole is inserted a positioning member which selectively engages in one of the slots.

A lower gate type semiconductor device, in which, for increasing an on-current of a lower gate type thin film transistor and restricting an off-current, there is provided a gate-controlled offset region different from a channel region in one or both conductivity types. This region increases the on-current of the transistor, provides a reduction of a leakage current, and restriction of a subthreshold coefficient. A two-dimensional size can also be reduced by altering the gate height. The on-current is increased, and the leakage current is reduced in the device. The offset region is composed of a semiconductor material and is formed at the end of a drain region of the device.

An image reading apparatus has more than one CCD for reading an image, the CCDs or other sensors partly overlapping to form an overlapped reading region. A mark such as a thin black line is used for discriminating the overlapped reading region, a liquid crystal device is provided for displaying the determined overlapped reading region, and a joint correction circuit is provided for correcting image data. Overlap or drop of image data is prevented.
