  • Patent number: 10936855
    Abstract: A display device includes: first and second cases that are connected to each other so as to be capable of moving relatively; a first image-capture unit that is provided in the first case and images a first image; a second image-capture unit that is provided in the second case and images a second image; a first display unit that is provided in the first case; a second display unit that is provided in the second case; a face recognition unit that determines whether the first image and the second image include a face seen from front; and a display control unit that causes the first display unit to display the first image and the second image when the face recognition unit determines that the first image includes a face seen from front, the display control unit causing the second display unit to display the first image and the second image when the face recognition unit determines that the second image includes a face seen from front.

  • Patent number: 8397003
    Abstract: There are provided a CPU connection circuit and a method by two CPUs by alternately conducting a changeover between two buffers disposed there between to prevent an event that data processing cannot be fully executed by the CPU on the receiving side. There is included a memory controller which monitors whether or not an amount of data stored by a CCPU 1 in either one of buffers 301 and 302 reaches a predetermined threshold value; when the amount of data stored by the CCPU 1 in the buffer 301, 302 reaches the threshold value, the memory controller requests an ACPU 2 to acquire the data stored in the buffer and changes the storage destination of data from the CCPU to the other one of the buffers; the threshold value is a value more than a unit quantity of data which the CCPU 1 sends to the buffer 301, 302.

  • Patent number: 8355326
    Abstract: There are provided a CPU connection circuit and a method wherein the CPU connection circuit is a circuit to be employed by two CPUs by alternately conducting a changeover between two buffers disposed therebetween to prevent an event that data processing cannot be fully executed by the CPU on the receiving side. There is included a memory controller 303 which monitors whether or not an amount of data stored by a CCPU 1 in either one of buffers 301 and 302 reaches a predetermined threshold value; when the amount of data stored by the CCPU 1 in the buffer 301, 302 reaches the threshold value, the memory controller 303 requests an ACPU 2 to acquire the data stored in the buffer and changes the storage destination of data from the CCPU to the other one of the buffers; the threshold value is a value more than a unit quantity of data which the CCPU 1 sends to the buffer 301, 302.

  • Patent number: 7340624
    Abstract: This invention relates to a clock control system including a CPU, a peripheral functional block for the CPU, a frequency multiplication circuit which multiplies the frequency of an input system clock and outputs the multiplied system clock, a plurality of frequency division circuits which divide the frequency of a signal output from the frequency multiplication circuit to generate clocks to be supplied to the CPU and peripheral functional block, and a clock controller which changes the frequency multiplication ratio of the frequency multiplication circuit to 1/N (positive integer) and then changes the frequency division ratio of the frequency division circuit arranged on the input stage of the peripheral functional block to 1/N in order to set the CPU to a low-power consumption mode, and a method of controlling the clock control system.

  • Patent number: 7016711
    Abstract: A cellular phone of folded type has a cover panel and a base panel coupled by a hinge for swiveling of the cover panel between a folded state and a developed state. The base panel mounts thereon a touch-sensitive panel whereas the cover panel mounts an image projector for projecting an image of keyboard information onto the touch-sensitive panel. The keyboard information includes a label for each of the keypads for designating the function of the keypad, and switched based on the input mode of the cellular phone.
