  • Patent number: 11657632
    Abstract: An image processing device comprising a processor configured to: determine presence or absence of a face image for each of a plurality of pieces of image data read from at least one image presenting medium, and decide a relationship for the plurality of pieces of image data, based on a result of the determination. The relationship is a front and back of the image presenting medium or a page order, and the processor is further configured to: decides that image data including a face image is on a front side of the image presenting medium or on a page before image data not including a face image.

  • Patent number: 10970579
    Abstract: An image processing apparatus includes a storage device for storing a position of a predetermined region in an image conforming to a predetermined format, a processor for acquiring an input image including a character recognition target region, cutting out a region corresponding to the character recognition target region from the input image or an image generated from the input image to generate a corrected image in which the region is placed at the position of the predetermined region in the image conforming to the predetermined format, and detecting a character from the corrected image, and an output device for outputting information related to the detected character.

  • Patent number: 7319484
    Abstract: A method for processing images comprises the steps of performing the reception of data through the net work, inputting image data obtainable in accordance with the designated input mode, managing the storage of the data received in the receiving step and the image data inputted in the input step to the memory, and intervening between the operations of the reception step and the input step in accordance with the storage management in the controlling step. With the method thus structured, the compression ratio of the input image is heightened by changing the current photographing mode if the added value of the estimated reception data through communicating means and the data side of photographed image predetermined by the current photographing mode should exceed the remainders of memory in the storage, hence making it possible to implement the compatibility of immediacy between the image input and the communication by dealing with any sudden reception during photographing.

  • Patent number: 6708818
    Abstract: The crossover conveyor chain system includes a first conveyor chain (S1) and a second conveyor chain (S2) crossing the first conveyor chain (S1) to transfer the product from the first conveyor chain (S1) to the second conveyor chain (S2) while reorienting the product to a direction nearly perpendicular to that on the first conveyor chain (S1). The first conveyor chain (S1) is supported on an end bar (10) or a small-diameter sprocket, and the second conveyor chain (S2) is formed a plurality of chain unit pairs each including at least two types of chain units (A) different in length from each other and a coupling pin (B). Each of the chain units (A) has front convex portions (1) and front concave portions (3), disposed alternately at the front thereof, rear convex portions (2) and rear concave portions (4), disposed alternately at the back thereof, and a transfer overhanging portion (7) formed integrally at one lateral thereof.

  • Patent number: 6196381
    Abstract: A chain unit has a central rib extending transversely and protruding portions extending from the rib to the front and rear side alternatively. The protruding portion is defined by two vertical side walls extending from the rib with the same height and a closed end portion combining the end portions of side walls. The closed end portion has an opening so as to enable the chain units to be placed in a row and column by being coupled with a connecting rod. At least two connected end portions are cylindrical shaped so as to surround the opening, and the cylindrical surface of the two closed end portions engages with a tooth of the sprocket which enters between the side walls. At least two corresponding recesses are formed in the lower surface of the rib for providing enough space to accept the tooth of the sprocket. The bottom of the chain unit has a circular arc surface extending from the rib towards the front and rear sides.

  • Patent number: 6050397
    Abstract: A conveyor chain unit possessing a central straight rib extending longitudinally from one end of the unit to the other end. The rib has a vertical height extending from the conveying surface to the bottom surface of the unit. A plurality of pairs of vertical side walls extend from the rib perpendicular to through-holes to form projections. The projections are positioned alternately on opposite sides of the rib having equal interval spacing. The number of the projections on one side is even and identical to the projections on the opposite side. At least one pair of projections positioned on opposite sides of the rib have recesses that are formed at the rib, and the projections are connected along the full height of the rib and spaced in a manner that chain units may be coupled together interchangeably via projections on either side of the rib.
