Abstract: There is provided an image signal processing apparatus, comprising a demosaic processing unit receiving input of mosaic image data of each of signals obtained by a single plate imaging device having an element array composed of visible light obtaining elements obtaining visible light signals, and invisible light obtaining elements obtaining signals including invisible light components, and generating a demosaic image of each of the obtained signals; and a noise reduction processing unit receiving input of the demosaic image to execute correction of pixel values of the demosaic image obtained by the visible light obtaining elements on the basis of edge information extracted from the demosaic image of the signals obtained by the invisible light obtaining elements.

Abstract: There is provided an image processing apparatus including a first polarizing unit that has a first polarization region and a second polarization region to transmit different polarized light corresponding to different viewing point images, a second polarizing unit that includes a third polarization region to transmit only transmission light of the first polarization region, a fourth polarization region to transmit only transmission light of the second polarization region, and a total transmission region to transmit the total transmission light of the first polarization region and the second polarization region, an imaging element, and an image processing unit that executes signal processing with respect to an output signal of the imaging element. The image processing unit executes correction processing to generate a two-dimensional image and executes image conversion of the two-dimensional image to generate a left eye image and a right eye image for three-dimensional image display.

Abstract: A video signal processing apparatus includes an image sensor and an infrared component remover. The image sensor receives light through a color filter, the color filter including long-pass filters only or a combination of a long-pass filter and an all-transmissive filter. The long-pass filters in the color filter a visible-light transmissive long-pass filter for permitting a visible-light component and an infrared-light component to pass therethrough and an infrared-light transmissive long-pass filter for permitting an infrared-light component to pass selectively therethrough. The infrared-light component remover removes an infrared-light component contained in a signal having passed through the visible-light transmissive long-pass filter, with transmittance data of an infrared-light region of the visible-light transmissive long-pass filter and the infrared-light transmissive long-pass filter applied.

Abstract: An encoding apparatus that converts input digital data and an input clock into three-bit six-state transition encode outputs and outputs them is disclosed. The encoding apparatus has a first state transition control section, second state transition control section, and an output selection section. The first state transition control section changes a state of first data at a positive edge of the input clock. The second state transition control section changes a state of second data at a negative edge of the input clock. The output selection section alternately selects the state of the first state transition control section and the second state transition control section.

Abstract: Noises are reduced in an image picked up in natural light without using lighting equipment that affect the picked up image. The present invention provides an image processing apparatus that includes an image acquisition unit that acquires a visible light image and an invisible light image corresponding to the visible light image, and a noise reduction unit that reduces noises of the visible light image by using the invisible light image.

Abstract: A network is to be constructed in which the relaying time is reduced to as short a time as possible. A network switch 1 checks the first one bit of an input header IHD of a packet. If the first one bit of the input header IHD is 0, the packet is relayed to an output port 39. The address 0, used for relaying, is moved to the leading end of the output trailer OTL in an output packet OUTpack.

Abstract: A superior portable information terminal of the palm size having a keyboard unit wherein the portable information terminal includes a polyhedral structure having a number of component faces including a first component face which accommodates a display screen and a second component face provided adjacent the first component face and having an inputting key set including a number of key tops arranged in a zigzag pattern. Each of the key tops has a rib-like projection formed along a peripheral edge thereof. In an operation condition wherein a user holds the portable information terminal with one hand and observes the display screen, the user can perform key inputting operation using the fingertips of the hand with which the body of the apparatus is held. Further, the user can search for the location of any key through the sense of touch on the rib-like projection or projections obtained from a fingertip.
