Abstract: A scanner system digitizes 35mm transparencies or negatives, and converts the image to a format compatible with popular microcomputer systems. This scanner system can accommodate various formats, and has variable zoom, pan and window size. Color separation is accomplished by an illumination arrangement causing rapid sequential generation of red, green and blue components. A low wattage light source is used, and color balance is achieved by adjusting the respective exposure times of the three primary colors. The system has internal calibration to achieve repeatable color balance. The system implements a wide variety of color coding schemes ranging in resolution from 1 to 24 bits. An adaptive process compresses the data in order to optimize the color selection process. The illumination optics are anamorphotic for high efficiency. Mechanical and electrical interfaces are compatible with a conventional 5-1/4" floppy disk drive standard.

Abstract: Three series connected inverters ( 38 ,  40 ,  42 ) are attached to a tank circuit ( 18 ) which includes an inductance ( 12 ,  14 ) and a capacitance ( 46 ,  48 ). Negative feedback from the third inverter ( 42 ) to the first inverter ( 38 ) biases the inverters at the midpoint between the bistable low and high logic level states. Positive feedback from the second inverter ( 40 ) to the tank circuit induces oscillation in the tank circuit. The negative feedback is decoupled at the resonant frequency and the energy delivered to the tank circuit from the positive feedback maintains a low level oscillation in the tank circuit. Negative feedback around the three inverter digital circuit prevents lockup in the event of power loss or momentary short.

Abstract: A drop-on-demand ink jet print head (9) has an ink pressure chamber (22) coupled to a source of ink (11) and an ink drop ejecting orifice (103) with an ink drop ejection orifice outlet (14). An acoustic driver (36), in response to a drive signal (100), produces a pressure wave in the ink and causes the ink to pass outwardly through the ink drop ejecting orifice (103) and the ink jet ejection orifice outlet (14) of the ink jet print head (9). In accordance with the present invention, controlling the operation of the ink jet print head (9) with a particular drive signal reduces print quality degradation resulting from rectified diffusion, which is the growth of air bubbles dissolved in the ink from the repeated application of pressure pulses to the ink residing within the ink pressure chamber (22) of the ink jet print head (9), such pressure pulses causing the application of pressures below ambient pressure. This method of controlling the operation of the ink jet print head (9) applies pressure below ambient pressure to the ink residing within the ink pressure chamber (22) of the ink jet print head (9) at magnitudes less than the threshold pressure magnitude that leads to the air bubble growth.

Abstract: A low density image is generated by replacing a pixel block of M x N pixels in an original image by a representative pixel. A subject image area for coloring process is then specified in the low density image, and the subject image area is painted with a desired color. The low density image is then magnified to form a high density image, and the high density image and the original image are compared with each other whereby another image is composed from the two images. Black image areas in the composed image area are finally changed to white. In the composed image, the desired color is allocated to pixels which have the desired color in the high density image and which are black in the original image while "white" is allocated to the other pixels. Pin holes, which are not specified as subject image areas, are not filled with the desired color, and is thus efficiently eliminated. Accordingly, pin holes are eliminated simultaneously when the subject image area is filled with the desired color.
