Although push buttons, jog dials, and the like are used for frame-by-frame control, these operations are not necessarily linked to human intuitive operations. In addition, in order to use a push button or a jog dial in a portable device, the use surface area on the panel of the device becomes large, a space is required in terms of a mounting surface, and also in terms of cost. It is not suitable because it is expensive. Also, since a plurality of switches are required, software control becomes complicated accordingly. Cannot be controlled as a series of operations.

In FIG. 1, 1 is a touch panel, 2 is a panel display device, 3 is an A / D converter, 4 is a mechanical controller, 5 is a CPU, 6 is a memory, 7 is a display unit, 8 is a servo unit, 9 is a disk, and 10 is a disk. It is a data processing unit. The touch panel 1 overlaid on the surface of the display device 2 such as a liquid crystal panel outputs a voltage corresponding to the position coordinates according to the movement of the operator's finger or pen, and A / D
The converter 3 converts it into a digital value and sends it to the mechanical controller 4. The mechanical controller 4 sends the coordinates (x, y) currently pointed to by the processor to the CPU 5. CPU
Numeral 5 always calculates a displacement (dx or dy) with respect to coordinates (x, y) that change every moment.

Here, a case in which only the x-direction displacement dx is used will be described. The CPU 5 accumulates dx over time (this is referred to as Sx). If the value of Sx at a certain moment is positive, the moving image is reproduced in the forward direction, and if the value is negative, the moving image is reproduced in the reverse direction ( The reverse combination is also conceivable). During reproduction, the absolute value of Sx is reduced, and when Sx is '0', a still image is reproduced.

遅くするようにしても良い。FIG. 2 shows a flowchart of the reproduction process of the CPU 5 in this embodiment. In FIG. 2, when starting at step 100, first, the x coordinate of a finger (or pen) on the touch panel 1 is detected (step 10).
1). Next, a difference dx from the previously input x coordinate value is calculated (step 102). The calculated difference dx is an integrated value S
x (step 103). As a result, if the value of the integrated value Sx is 0, the current output image is continuously reproduced as a still image (step 104). Integrated value Sx
If is not 0 but positive (step 105), step 1
In step 06, frame advance control is performed in the forward direction according to the value of the integrated value Sx. At this time, the frame feed speed may be increased when the integrated value Sx is large, and may be decreased when the integrated value Sx is small. If the frame advance advances, the value corresponding to the number of frames sent is integrated value Sx
(Step 107). Since the value of the integrated value Sx becomes smaller by the subtraction, the frame feed speed may be reduced by that amount.

At this time, when the absolute value of the integrated value Sx is large, the frame feed speed may be increased, and when the absolute value of the integrated value Sx is small, the frame feed speed may be reduced. As the frame advance proceeds, a value corresponding to the number of transmitted frames is added to the integrated value Sx (step 109). Since the absolute value of the integrated value Sx becomes smaller by the addition, the frame feed speed may be reduced accordingly.

Data read from the disk 9 or tape is sent to the data processing unit 1

On the other hand, a method of changing the reproduction mode according to the value of the integrated value Sx is also conceivable. The playback modes include a normal playback mode, a fast-forward playback mode, and a frame-by-frame playback mode. Each of the modes has forward and backward two-way feeding, and is applied to a total of six types of playback modes.

モードの関係を図表にして示した。FIG. 3 shows a flowchart of the reproduction process of the CPU 5 in this embodiment. In FIG. 3, steps up to step 205 correspond to steps up to step 105 in FIG. If Sx is positive in step 205, the process proceeds to step 206, where it is determined whether Sx is greater than a second threshold value T2. If Sx is greater than the threshold value T2, a forward fast-forward playback mode is entered (step 207). Sx is second
If it is smaller than the threshold value T2, the process proceeds to step 208, and it is checked whether Sx is larger than a first threshold value T1 smaller than T2. If it is larger than the threshold value T2, the normal reproduction mode in the forward direction is entered (step 209). If Sx is smaller than the first threshold value T1, a frame forward mode is set in the forward direction, and frame forward control is performed in the forward direction (step 21).
0). At this time, if the value of the integrated value Sx is large in accordance with the value of the integrated value Sx in this range, the frame feed speed is increased,
When the value of the integrated value Sx is small, the frame feed speed may be reduced. As the frame advance progresses, a value corresponding to the number of transmitted frames is subtracted from the integrated value Sx (step 211). Since the value of the integrated value Sx becomes smaller by the subtraction, the frame feed speed may be reduced by that amount. If Sx is negative in step 205, step 212
Proceed to. Subsequent processes are the same as in the case of the forward direction, and thus description thereof is omitted. FIG. 4 is a table showing the relationship between the value of Sx and the mode in this embodiment.

も考えられる。In the above example, an example has been described in which the reproduction control is changed in accordance with the current value of Sx. In addition, Sx (corresponding to the initial stroke) within a fixed time from the first input is held as a fixed value. However, a method is also conceivable in which reproduction is performed inertially at a speed proportional to the absolute value of the fixed value even if no input is made thereafter. If there is no input for a certain period of time,
An example is also conceivable in which the number of playback frames (frame rate) per unit time is gradually reduced, and the image is eventually stopped as a still image.

に適した構成が実現できる。According to a second aspect of the present invention, the integrating means integrates the movement of the instructing means with positive and negative polarities, and the reproduction control means determines that the integrated value of the integrating means is positive and the first predetermined value. If the value is smaller than the first predetermined value, the frame advance mode in the forward direction is changed to the first frame.
If the integrated value of the integrating means is positive and larger than the second predetermined value, the normal fast forward mode is performed when the integrated value is smaller than a second predetermined value. When the integrated value of the integrating means is negative and larger than the third predetermined value, the reproduction mode is changed to the frame forward mode in the negative direction.
When the integrated value of the integrating means is negative and smaller than the third predetermined value and larger than the fourth predetermined value which is smaller than the third predetermined value, the normal reproduction mode in the negative direction is changed to the integrated value of the integrating means. Is negative and smaller than the fourth predetermined value, the fast forward reproduction mode in the negative direction is selected, and when the integrated value of the integrating means is 0, still image reproduction is performed. As a result, the switching of the playback operation mode can be performed by the operation of a human finger on the touch panel surface, which makes the operation intuitive and easy, and is suitable for a portable device that is smaller and has fewer operation points.
