This image pickup apparatus includes: an image pickup unit including an image pickup element; a first video signal processing unit that generates a first video signal having a first resolution from a pixel signal obtained by the image pickup unit; a second video signal processing unit that sets a plurality of divided areas for spatially segmenting the first video signal generated by the first video signal processing unit, cuts out the first video signal in a region smaller than a size of the corresponding divided area as a block from the first video signal in each of the individual divided areas, and connects them to one another, to thereby generate a second video signal having a second resolution lower than the first resolution; and a view finder that displays the second video signal.

Image pickup apparatus, video signal processing apparatus, and video signal processing method

This image pickup apparatus includes a VF signal processing unitthat downconverts a first video signal having a 4K resolution to thereby generate an downconverted video signal having an HD resolution, calculates each of pieces of differential data from an average luminance value of luminance values of 2 horizontal&#xd7;2 vertical pixels of a center portion in a region of 4 horizontal&#xd7;4 vertical pixels of a first video signal, which correspond to 2 horizontal&#xd7;2 vertical pixels of the downconverted video signal, calculates an addition value for each pixel of 2 horizontal&#xd7;2 vertical pixels of the center portion on the basis of each piece of differential data, and individually adds the luminance values of 2 horizontal&#xd7;2 vertical pixels of the downconverted video signal to thereby generate a second video signal having the HD resolution.

This video transmission apparatus includes: a first control unit that divides video data into a plurality of channels in units of one or more specified number of consecutive frames, and gives a change by a reversible method to the video data of a specific area in the frame of the video data of each channel, the specific area corresponding to the channel; and a plurality of first video transmission interfaces that each transmit the video data of each channel to which the change is given.

Video transmission apparatus, video reception apparatus, video transmission method, and video transmission system

A signal transmitter includes: a main transmission line-transmitting portion that transmits optical signals through main transmission lines; a backup transmission line-transmitting portion that transmits the optical signals through backup transmission lines paired with the main transmission lines; a selector that selects a transmission line to be used for transmitting the signals from any of the transmission lines through which the signals are transmitted by the main transmission line-transmitting portion and the backup transmission line-transmitting portion; and a controller that, when a fault occurs on at least one main transmission line, outputs a switching command to the selector based on information identifying the main transmission line with the fault, thus causing the main transmission line-transmitting portion to stop transmitting the signals to the main transmission line with the fault, while causing the backup transmission line-transmitting portion to transmit the signals being transmitted to the main transmission line with the fault to the backup transmission lines.

Signal transmitter, signal receiver, and signal transmission system

An imaging apparatus operating on the basis of setting information determining quality of a captured image. The apparatus includes: imaging means for performing image processing in accordance with the setting information; image-signal processing means for performing signal processing of the image captured in accordance with the setting information; when a read request is input in a state of being connected with an image recording medium including setting-information recording means storing specific setting information recording a setting value for obtaining a specific image quality and image-information recording means recording image information including captured image data, setting-information reading means for reading the specific setting information stored in the setting-information recording means of the medium; and control means for changing the setting information on the imaging means and the image-signal processing means on the basis of the specific setting information and controlling the imaging means and the image-signal processing means.

Imaging apparatus, image recording medium, and method of setting quality of captured image

A picture signal processing circuit includes a filter unit, a memory and a main control unit. When a display operates in a first display mode, the filter unit removes high-frequency components from first picture signals supplied in a first picture size from an imaging device, to provide second picture signals. When the display operates in a second display mode, the picture signals are provided unchanged. The memory stores the first and second picture signals, reads out the second picture signals, changes the second picture signals from a first picture size to a second picture size and supplies those second picture signals to the display when the display operates in the first display mode. The first picture signals corresponding to a picture clipped from the first picture size to the second picture size are read out to the display when the display operates in the second display mode. The main control unit controls switching between the first picture signals and the second picture signals from the memory according to whether the first or second display mode is selected.

In a process for hydrating a nitrile compound by the action of a microorganism having nitrilase activity to convert the nitrile compound into the corresponding amide compound, the performances such as yield and reaction velocity are markedly enhanced by irradiation of the microorganism with light. The process of the present invention is characterized in that (a) the microorganism having nitrilase activity is a positive gram-staining microorganism, (b) the microbial cells are allowed to accept light energy of at least about 1.times.10.sup.-2 .mu.E/g microbial cells second before termination of the hydration reaction, and (c) the hydration reaction is carried out in a vessel composed at least partly of a non-light transmitting material.
