摘要： A graphic character that has a character matrix with a number of character units that are indivisible at least in either a horizontal direction or a vertical direction is scaled by dividing the character matrix into one first and at least one second character segment, each comprising at least one of the character units. The first character segment is symmetrically scaled using a first scaling factor and the second character segment is scaled using a second scaling factor different from the first scaling factor.

摘要： A method for detecting a freeze-frame condition comprises receiving a sequence of images from at least one digital device; selectively encoding a first subset of the sequence of images using a first coding scheme that causes an adjustment to an image characteristic of the selected images being encoded; selectively encoding a second subset of the sequence of images using a second coding scheme; storing the first encoded subset and second encoded subset; retrieving the stored first encoded subset and second encoded subset; selectively decoding the first subset of the selected images using the first coding scheme and selectively decoding the second subset of the selected images using the second coding scheme to re-create the sequence of images. A freeze-frame condition in the re-created sequence of images is identifiable based on a plurality of decoded images being different with respect to the image characteristic across multiple decoded image frames.

摘要： A data logging system for logging input data received from a data source is described. The data logging system has a data storage memory. A data input is arranged to repeatedly receive input data having a temporal input data resolution. A write controller is arranged to write newly received input data as received via the data input into the data storage memory. The writing comprises writing the newly received input data at the temporal input data resolution. The writing comprises keeping recent data at the temporal input data resolution in the data storage memory, and overwriting part of old data with newly received input data while keeping another part of the old data in the data storage memory at lower data resolution.

摘要： To determine the noise contained in a picture, it is proposed first to determine homogeneous picture regions of the picture (100-102) and then to measure the high-frequency signal component in these homogeneous picture regions (BR). The measurement of the high-frequency signal components is here averaged over many measurement points, i.e. over many homogenous picture regions (BR), and is processed into a noise figure (NOISE_SUM) (103-104). In this way, the quality of the picture can be measured directly in the picture content.

摘要： The invention relates to a method for changing the image size of video images, in which a decimation of video image signals (V) by an integral decimation factor (MHD, MVD) is carried out, and the decimated video image signals are subsequently read into an image memory for buffering.In order to achieve better possibilities of adjusting the image reduction with a relatively low outlay and high image quality, a fine decimation of the video image signals (V) is additionally carried out before buffering by a fine decimation factor (SHS, SVS) which can be adjusted to non-integral values, and a total decimation factor (MH, MV) relevant to the decimation of the video image signals (V) is formed from the integral decimation factor (MHD, MVD) and the fine decimation factor (SHS, SVS).

摘要： An integrated circuit comprises a write bus coupled to a register for storing control data. A storage unit is arranged to store reference signature data encoding a reference collective state of the register. First logic circuitry generates actual signature data encoding the actual collective state of the register. Second logic circuitry is coupled to the storage unit, receives the actual signature data and compares the actual signature data with the reference signature data. The second logic circuitry comprises an alert output to provide an alert signal in response to the comparison identifying a difference between the actual signature data and the reference signature data, thereby ensuring detection of a data integrity error in respect of the register. An alert inhibitor comprises a control input and is responsive to the control input and arranged to inhibit selectively onward propagation of the alert signal from the alert output.

摘要： A device for correcting the phase of a vertically distorted digital picture receives picture data and a vertical phase correction signal, and assigns lines of the digital picture to a first half picture and to a second half picture. The lines of the second half picture are phase corrected with respect to the first half picture and the first and second half pictures are displayed sequentially. The phase correction is determined in response an increment signal that describes the change of an imaging factor in the veritcal direction of the digital picture on a line-by-line basis and a picture position signal indicative of whether the first half picture or the second half picture is being output.
