Abstract: The present technology relates to a transmitter apparatus, an information processing method, a program, and a transmitter system capable of easily transmitting a wideband signal. The transmitter apparatus includes: a first acquisition unit that obtains first transmission control information; a second acquisition unit that obtains second transmission control information similar to information input to another transmitter apparatus; and a generating unit that processes transmission target data based on a parameter contained in the first transmission control information and generates data including the processed transmission target data and the second transmission control information. The present technology can be applied to a transmitter apparatus that transmits a DVB-C2 signal.
Abstract: A plurality of preliminary image signals is acquired by carrying out preliminary image acquisition of a subject, before actual image acquisition, with different amounts of light received by an image acquisition device. Subsequently, a dynamic range and an amount of noise, or an S/N ratio, for a case in which the plurality of preliminary image signals is combined is calculated, and a received-light-level difference of the image acquisition device among a plurality of actual image signals acquired through the actual image acquisition is calculated on the basis of the dynamic range and the amount of noise, or the S/N ratio. Then, by carrying out the actual image acquisition on the basis of the calculated received-light-level difference, a plurality of actual image signals with different received light level is acquired. These actual image signals are combined to acquire a combined image.
Abstract: An imaging apparatus comprising: A spatial light modulator (30) operable to receive incident light (34) representing an incident light image and to intensity modulate said incident light to form spatially modulated (38) light; and an image capture device (42) operable to receive said spatially modulated light and to detect an intensity value for different portions of said spatially modulated light to form a modulated light image therefrom; wherein said spatial light modulator attenuates different parts of said incident light by different proportions such that intensity values of said incident light image are given by a combination of intensity values of said modulated light image captured by said image capture device and data representing proportions of attenuation applied to corresponding parts of said incident light image by said spatial light modulator.

Abstract: A multi-standard integrated television receiver is disclosed. According to the invention, a RF tracking filter is provided to receive a RF signal and then filter out a fifth order and above harmonics and a band-pass filter is provided to further eliminate harmonics. Moreover, a double quadrature mixer is provided to remove third order harmonics. Accordingly, the quality factor requirement of the RF tracking filter and the linearity requirement of the band-pass filter are relaxed. Thus, the RF tracking filter and the band-pass filter can be fully integrated without any external components.
Abstract: The present invention provides an image shake correcting apparatus including a shake signal output device, an image displacing device, and an image shake correcting device, comprising: a pan/tilt detecting device which detects panning or tilting of said optical system; an image shake correction stopping device which stops image shake correction by said image shake correcting device when said panning or tilting has been detected; a pan/tilt end detecting device which detects the end of said panning or tilting; an image shake correction restarting device which causes said image shake correcting device to resume image shake correction when the end of said panning or tilting has been detected; and an object frequency band altering device which raises, for a prescribed length of time after the resumption of said image shake correction, the cutoff frequency on the low frequency side of the frequency band covered by said image shake correction.
Abstract: An image signal processing device of the present invention includes an RGB-YC conversion for converting color component signals output from a CCD (Charge Coupled Device) image sensor to luminance signals and components thereof lying in a high frequency range. The luminance signals and their components lying in a high frequency range are fed to a first, a second and a third low pass filter (LPF), respectively. Luminance signals output from a third LPF are fed to an adder while components lying in a high frequency range are fed from the first LPF to a selector. Further, the components output from the second LPF are fed to the selector via a resolution correcting section. The selector selects either one of the two different kinds of components input thereto. The adder adds the luminance signals output from the third LPF and the components selected by the selector and thereby outputs second luminance signals.
Abstract: An anti-color aliasing filter for a digital imaging system is includes a first filtering region that allows any color to pass through. The filter also includes a second filtering region adjacent to the first filtering region to allow a particular color or colors to pass through in order to adjust the color frequency response of the digital imaging system to the remaining colors without affecting the frequency response of the digital imaging system to the colors passing through the second filtering region, such that color aliasing is minimized in the digital imaging system.
