摘要： An image processing apparatus includes: input means for inputting a video signal; decoding means for decoding the video signal; filtering means for performing predetermined filtering on the decoded video signal; and control means for calculating an average bit rate by dividing an amount of bits generated per predetermined data unit from the decoded video signal, and controlling a characteristic of the filtering in accordance with the average bit rate. When the video signal is input per image file, the control means calculates the average bit rate by dividing a file size of the image file by a playback time corresponding to the file size, and when the video signal input is sequentially input per picture, the control means calculates the average bit rate by dividing a sum of generated bits per picture for a predetermined number of frames by the predetermined number of frames and the frame rate.

摘要： An image processing apparatus prevents the inappropriate application of error diffusion and adaptively applies palette conversion functions according to the properties of the source. A processing subsystem performs various processing with respect to an original video source. A palette converter converts the palette bit depth, having modifiable palette conversion functions for creating the illusion of expressing the pre-conversion palette tones in the post-conversion image. A controller turns on the palette converter, turns off the palette converter, or modifies the palette conversion functions thereof, in accordance with at least original source information and system-wide settings information.

摘要： An optical pulse evaluation device and an in-service optical pulse evaluation device is disclosed which are capable of characteristics evaluation of an optical pulse itself or a sample launched therein in a relatively high bit-rate region. The optical pulse evaluation device evaluates a pulse waveform expressing an optical intensity of the optical pulse, an instantaneous frequency of the optical pulse, or a modulated light prepared by modulating the optical pulse in a light source end. The optical pulse evaluation device also observes a waveform change after a known optical pulse is passed through a device such as an optical fiber to evaluate a waveform deterioration or a compensation behavior caused by the device. The in-service optical pulse evaluation device is capable of measuring a wavelength dispersion in an optical communication.
