摘要： In a transmission chain having series-connected a TSC unit, an encoder, a transmission path, a decoder, and an up-converter, characteristic value extracting units are connected to input/output points A, B, C, and D of these transmission processing units respectively. Each characteristic value extracting unit extracts characteristics like an average value m and a variance σ2 of luminance of a picture, for example. These characteristic values are transmitted to a central monitoring unit via a low-speed line. A characteristic value comparator compares the characteristic values. When a difference equal to or larger than a predetermined threshold value has occurred in the characteristic values, the characteristic value comparator decides that an abnormality has occurred in the image in transmission. According to the present invention, it is possible to provide an apparatus for assessing quality of a picture in transmission and an apparatus for remote-monitoring picture quality of a picture in transmission that are capable of assessing the picture quality of a transmission picture in high precision, during an actual transmission of the picture.

摘要： Road area blocks of monitoring camera video data are extracted by a road area block extractor, and motion vectors are calculated by a motion vector calculator. A motion vector direction detector detects the directions of the motion vectors. In a normal state, the mean value Θ and the variance σe2 of the directions θ of the motion vectors are calculated and accumulated in a statistics memory. In detection of road obstructions, the directions of the motion vectors detected by the motion vector direction detector are transmitted to an abnormal motion vector degree Q calculator. An abnormal motion vector degree Q is calculated on the basis of the statistics accumulated in the statistics accumulated in the statistics memory. A comparator compares the abnormal motion vector degree Q with a threshold. When the abnormal motion vector degree Q is equal to or larger than the threshold, road obstructions are decided. Therefore, according to the present invention, a detection apparatus for road obstructions which is not easily affected by changes in brightness and color in an image and which is not easily adversely affected by the color of a running vehicle is provided.

摘要： A first characteristic value extracting unit extracts a characteristic value from a picture transmitted from a transmission side, and a second characteristic value extracting unit extracts a characteristic value from a picture received on a reception side. These extracted characteristic values are supplied to a central monitoring unit through low speed lines, respectively. In the central monitoring unit, an MSE (mean square error) is assessed from the data by an MSE assessing unit. The first and second characteristic value extracting units divide an input picture into blocks, subject the blocks to an orthogonal transformation, or subject the blocks to PN sequence multiplication before the orthogonal transformation, and extract and output orthogonal transformation coefficients. The MSE assessing unit determines the differences between corresponding coefficients on the transmission side and the reception side and squares the differences, adds the squared differences for every coefficients or every blocks, and assess an MSE based on the added values referred to a table. With this operation, the MSE can be effectively assessed using a smaller amount of extracted data (accordingly, slower speed lines can be used in the central monitoring unit).

摘要： Received videos through A and B routes are inputted in first and second variable devices and then delayed by a first and a second frame memory by one frame to be inputted in a comparator. Alternatively, these signals A and B are further delayed by one frame by third and forth frame memories and also inputted in the comparator. The comparator compares the signals obtained by delaying the signals A, B, AF and BF by one line and one pixel, respectively, between the A and B routes with respect to all combinations so as to detect the difference between them. Then, a signal having the minimum difference is detected and a first and a second memory control signal to make the difference smaller are outputted to the first and second variable delay devices. By repeating the processing, a horizontal difference, a vertical difference and a time axial difference are gradually, and then completely, corrected including when the original amount of the difference is larger than a frame delay.
