An image processing apparatus having various interrupt-handling capabilities when image formation is interrupted. In one aspect, image formation is interrupted after completion of a predetermined number of image formations when the size of a recording material is indicated as a first size, and image formation is interrupted after a completion of a predetermined number of image formations when a recording material is indicated as a second size. In another aspect, a condition for image formation is selected whereby in the case the selected condition is prevented (e.g., recording on wrong-sized paper), the condition is stored, and after the image formation has commenced, a stop command is inhibited and stored. In another aspect, data concerning image information is entered, the entered data is displayed, and images are formed sequentially in accordance with the data whereby the formation of the images may be interrupted and the remaining number of image formations may be stored and displayed. It is also possible to interrupt the image formation for a predetermined image formation count without entry by the operator.

A method of implementing a fast video encoder by approximating a frame motion vector is introduced. MPEG-2 encoding uses both field and frame vectors in the encoding process. To implement an encoder in an efficient manner, an approximated motion vector created from two field motion vectors is used. The frame motion vector may be determined using the two field motion vectors alone, or by using the two field motion vectors in conjunction with their respective absolute error values. By using the disclosed methods, a motion estimation part for generating frame motion vector is not necessary. Only two field motion estimation parts are required to determine the field motion vectors, the frame motion vector is then approximated using the two field motion vectors. The cost and complexity of a digital video encoder system is thereby reduced.
