Abstract: A mobile object control apparatus includes: a prediction unit that, with respect to a first mobile object and a second mobile object, predicts whether the first and second mobile objects collide with each other at an intersection; and a calculation unit that, when the first and second mobile objects collide with each other at the intersection, calculates a speed of the first mobile object at which the collision can be avoided at the intersection, wherein the prediction unit extracts a third mobile object that is in an intersection area and has passed through the intersection, and estimates that the third mobile object is a mobile object that has a high possibility of colliding with the first mobile object at the intersection, the intersection area being set at the intersection through which the first mobile object passes.

Abstract: A picture number of an image to be displayed on a liquid crystal display is compared with index data contained in an index section of a work memory to produce a display signal to be delivered to the liquid crystal display by using compressed or non-compressed data which has been left in a data section of the work memory when it is determined that the compared data coincided with each other.
