  • Patent number: 8780407
    Abstract: An image processing apparatus is connected to an image reading apparatus which reads a read area set on a scanner platen in accordance with a size of a document placed on the scanner platen so as to create image data in which an image of the document is shown. The image processing apparatus includes a document detection section and an instruction section. The document detection section creates, based on the image data supplied from the image reading apparatus, document area information indicative of an area where the document is placed on the scanner platen. In a case where the area indicated by the document area information is not completely encompassed by the read area, the instruction section sets a reread area which completely encompasses the area indicated by the document area information and causes the image reading apparatus to read the reread area.

  • Patent number: 8781059
    Abstract: A shift register is formed by connecting unit circuits 11 in multi-stage. One electrode of a capacitor Cap2 in the unit circuit 11 is connected to the gate terminal (node N1) of a transistor T2, and the other connected to a node N2. A compensation circuit composed of transistors T3 to T5 provides a clock signal CKB to the node N2 when the node N1 potential is at low level, and applies a low-level potential to the node N2 when the node N1 potential is at high level. Accordingly, even when the gate potential of the transistor T2 changes with a change in a clock signal CK, a signal that cancels out the change is provided through the capacitor Cap2, stabilizing the gate potential of the transistor T2. Thus, a change in the control terminal potential of an output transistor associated with a change in a clock signal is prevented.

  • Patent number: 8780037
    Abstract: A display method of an embodiment (i) determines a suitable length of an off period of an LED in accordance with a gray scale transition time, i.e., a time during which a transmittance of a liquid crystal is being changed, and (ii) turns off a light source for the determined length of the off period in a first half part of a one frame period. This makes it difficult for a halfway change in a gray scale transition to be reflected in a brightness of a pixel. Also, by performing a gray scale transition emphasis process to a display signal when the gray scale transition is caused, it is possible to increase the brightness of the pixel in the midst of the gray scale transition and to reduce a response time of the pixel. As such, it is possible to further improve a quality of moving image display.
