A luminance cumulative integrating method in image processes comprises the steps of: storing the positions of all of the unit regions constituting at least one block region to be detected as position information into a plurality of memory areas whose readout order has been predetermined in one direction; storing the luminances at the respective positions of an optical image as luminance information corresponding to the position information; sequentially outputting the position information from the plurality of memory areas; taking out the luminance information corresponding to the position information from the luminance information stored; adding the luminance information; and thereby obtaining the block luminance of at least one block region.

A running guide system for an automotive vehicle planned for running in a sightseeing area or the like. Special running data including right or left turn, passage through a tunnel, running in a predetermined direction and passage on a slope are stored in a cassette tape together with distance data representing the distance from a start point in the form of a plurality of check point data. By collation of the running distance data actually measured and the special running condition data with the stored data, the automobile is guided audibly or visually. Geographical data or sightseeing data are also recorded in the cassette tape and reproduced in voice from time to time. When the automobile is displaced from the planned running route, an alarm is issued. When the automobile is restored to the planned running route, the planned running guide is restored.

The present invention concerns a method of measuring the shape of an injected substance and an automated apparatus for carrying out such a method. In the invention, an optical image of the injected substance, such as atomized fuel mist is projected on a photoelectric converter, and it is converted to video signal. The video signal is sampled at each picture element and the sampled data are memorized in a data memory unit and computed for obtaining a linear luminance distribution function, by determining a line to cut an optical image, then selecting line elements of a fixed length perpendicular to the cut line and computing an average luminance at the individual line elements. The linear luminance distribution function thus obtained stands for a sectional view of a shape of the injected substance mist. And judgment whether the shape is satisfactory or not can be executed on the basis of various shape factors extracted by use of the linear luminance distribution function. The present apparatus can judge, whether, for example, nozzle of a fuel injector is satisfactory or not with high precise.

In a speed display device of the numerical display type which comprises a speed sensor for producing an electric speed signal indicative of a travel speed of the vehicle, and an electric display responsive to the speed signal for providing a numerical display indicative of the travel speed of the vehicle, the improvement comprises an electric control device responsive to the speed signal for successively enlarging the size of the numerical display in accordance with rise of the speed level. Alternatively, the electric control device may be arranged to be responsive to the speed signal for successively inclining the shape of the numerical display in accordance with rise of the speed level.
