  • Patent number: 6496191
    Abstract: A character font generation apparatus generates a font of a character for the output of the character to an output unit. First, whether the character specified through the operation of an input unit can be output in a desired font based on a predetermined resolution of the output unit or not is determined. If the result of the determination is no, a stroke of the character is omitted to reduce the size of the character, to allow the correct output according to the predetermined resolution. The stroke omission is performed with reference to contents of a memory storing various information necessary for the character font generation and a priority determination rule indicating various information for determining the priority of stroke omission, so as to maintain the balance and to preserve the shape (contour) of the character.

    Abstract: A character font generation apparatus generates a font of a character for the output of the character to an output unit. First, whether the character specified through the operation of an input unit can be output in a desired font based on a predetermined resolution of the output unit or not is determined. If the result of determination indicates “output not allowed”, a stroke of the character is omitted to reduce the size of the character to allow the correct output according to the predetermined resolution. The stroke omission is performed with reference to contents of a DB (database) memory storing various information necessary for the character font generation and a priority determination rule indicating various information for determining the priority of stroke omission, so as to maintain the balance of the character such as center and centroid thereof and to preserve the shape (contour) of the character.

  • Patent number: 6130667
    Abstract: A character pattern generating apparatus includes a CPU and a memory for pre-storing character shape skeleton data, element skeleton shape data, element skeleton shape data, and element outline shape data. The CPU determines whether a thickness of a character is to be altered or not from a standard thickness, and determines whether the process of altering the thickness of each constituent element in the element outline shape data is to be performed by calculation, or by replacing the element with an alternative element in the case where character thickness is to be altered. The CPU then alters the thickness in the element outline shape data according to the determination and deforms the element skeleton shape data based on the character shape skeleton data. Associated therewith, the CPU alters the element outline shape data based on the altered element skeleton shape data and generates a character pattern from the altered element outline shape data.

  • Patent number: 5379369
    Abstract: Depth information generating section generates depth image information representing the class of the depth of each pixel in two-dimensional image information outputted from an image input section, according to depth information outputted from an input section. A stereoscopic image information generating section generates stereoscopic image information, based on the depth image information and the two-dimensional image information. Thereafter, an image for the left eye and an image for the right eye read by an image information output section are alternately displayed on the screen of an image display section under the control of a gate. In synchronization with the change-over operation of alternately displaying the image for the left eye and the image for the right eye, the stereoscopic section controls the opening and closing of liquid crystal shutters of liquid crystal shutter glasses.

  • Patent number: 4502401
    Abstract: An electronic sewing machine capable of sewing a buttonhole having a circular stitching part. The machine is operative selectively in one of automatic and manual modes. In the automatic mode, bight position of a needle and feed position of a feed dog are automatically controlled according to stored bight and feed data. In the manual mode, the bight and feed positions determined by the stored data are adjusted by a data adjusting circuit. The machine comprises a circuit which supplies the data adjustment circuit with a signal to inhibit the adjustment of at least the feed data for each stitch to be formed in the circular stitching part.

  • Patent number: 4495878
    Abstract: An electronic sewing machine capable of forming a buttonhole having a circular stitching part. The machine has manually operated members for setting thread thickness and button size. A stitch data generator is provided, which is capable of selectively generating one of plural different groups of stitch data for forming different buttonholes which have a different number of stitches at their circular stitching part. The specific group of stitch data is selected according to code signals fed in accordance with the positions of the manually operated members. The position of each stitch contained in the circular stitching part of the buttonhole is determined by each stitch data of the selected group. Thus, the desired buttonhole is sewn neatly without crowded or lean stitches.

  • Patent number: 4458612
    Abstract: A buttonhole sewing machine for automatically forming a buttonhole including right and left parallel side stitching parts, and another stitching part connected to the side stitching parts. The machine has a switch for detecting front and rear ends of each side stitching part, and is capable of sewing the buttonhole in divided parts on opposite sides of a longitudinal centerline thereof so that the two side stitching parts are stitched in the same work feeding direction. The machine comprises a control circuit generating a feed change signal when the number of stitches being formed in one of the side stitching parts has become equal the total number of stitches of the other side stitching part less a predetermined number, and a feed adjusting circuit for reducing a work feeding increment for a time interval between generation of the change signal and a signal from the switch, to avoid a difference in length between the side stitching parts.
