A quantizing number is determined using multiple stages of code amount estimating circuits. Thus, an optimum quantizing number may be selected from among a number of quantizing numbers which is not limited to the number of code amount estimating circuits. The optimum quantizing number is used to quantize a set of blocks of orthogonally transformed image data. The quantized data are encoded using a variable length code. The optimum quantizing number is the one which results in the greatest amount of data that is within a predetermined threshold, permitting an amount of encoded data to be recorded on a magnetic tape in a fixed format.

Apparatus for compression encoding video signals, comprising block segmenting circuits for segmenting a vertical interval, such as a field or frame, of video picture elements into a plurality of blocks of picture elements. An orthogonal transformation, such as discrete cosine transformation, of respective blocks is obtained, resulting in a two-dimensional array of transform coefficients of different values, the array being partitioned into respective areas. Each area is quantized with a respective quantizing value that differs for different areas. Preferably, a transform coefficient is quantized by dividing the value of the transform coefficients in an area by a divisor 2.sup.n/2, where n is an integer that differs in different areas. The areas of the two-dimensional array of transform coefficients are formed by partitioning the array in a direction substantially perpendicular to the oblique frequency axis of that array.

A CPU unit of PLC executes a motion control and a sequence control. The CPU unit stores a control program for executing the motion control using a CAM table, and a first CAM table and a second CAM table. When a microprocessor receives a predetermined instruction during execution of the control program, the microprocessor switches the CAM table used in the execution of the control program from the first CAM table to the second CAM table. On the basis of the switching of the CAM table, the microprocessor outputs the execution results of the control program using the second CAM table to an apparatus to be controlled.

A synchronous control apparatus capable of switching cam curves with ease and without delay is provided. A cam curve storing unit stores a representation of a first cam curve and a representation of a second cam curve. Before switch-over of the cam curves, a control unit finds a position command value to a driven-side member, after the switch-over of the cam curves, the control unit finds the position command value, and in a switch-over period of the cam curves, the control unit finds the position command value to the driven-side member based on a value obtained by utilizing first data based on the first cam curve or a position of the driven shaft and second data based on the second cam curve to provide a weighted average at each control timing.

When a work is set on a hot plate and a heat treatment is started and the like, an addition waveform of a target temperature is formed based on a previously formed data of an adjustment value, and a temperature is controlled by adding the addition waveform to the target temperature SP, and with the data of the adjustment value, the variation in temperature of the work is prevented using an interference matrix showing a relation between the target temperature SP and the temperature of the work.

A selectable operation amount is set as a threshold value according to an input operation amount, where if a determination value obtained by adding the input operation amount and an integrated operation amount or an output error accumulated value is greater than or equal to the threshold value, the threshold value is selected as the output operation amount, and if the determination value is not greater than or equal to the threshold value, a selectable output operation amount close to the threshold value is selected, and the ON/OFF control is performed with the selected output operation amount, while the selected output operation amount is subtracted from the determination value to correct the integrated operation amount, so that the input operation can be substantially output even if it takes an operation amount other than the selectable operation amount values.

The invention is configured such that a distance estimation device estimates a distance between a hot plate as an object to be treated and a work, with respect to which the work is placed to be thermally treated, based upon information on temperature of the hot plate such as an absolute value of inclination of the temperature of the hot plate, and a determination device compares the estimated distance with a threshold to determine the presence or absence of abnormality.

At least one kind of control signal concerning control of contents, added to specific locations inside contents data, is detected as first control information, and at the same time, at least one kind of control information concerning control of contents, embedded inside the contents data by a digital watermark, is detected as second control information. Consistency between the first control information as detected, and the second control information as detected is determined and on the basis of results of the determination, the control of the contents is executed. Thus, it is possible to reduce a possibility of the contents being improperly copied, thereby enabling the control with assurance of still higher safety.
