Abstract

PURPOSE:To realize a small sized and sophisticated picture reproducing device without increasing the number of operation keys by using one operation key so as to switch the reproducing mode and to set an interval time in the consecutive reproduction. CONSTITUTION:Power is supplied by the depression of a POWER key 1 and one picture is reproduced. When an UP key 3 is depressed, a picture to be reproduced is sent sequentially and a 2nd picture is reproduced. Let a time from the reproduction of a 1st picture till the depression of the UP key 3, that is, the reproduction time of the 1st picture be t1, then a 3rd picture is reproduced when the UP key 3 is depressed and when the UP key 3 is depressed for one second, the consecutive reproduction mode is set. In the consecutive reproduction mode, the time t1 being the reproduction time of the 1st picture is used as an interval and the picture is sequentially reproduced. In the consecutive reproduction mode, when the UP key 3 is depressed, the consecutive reproduction mode is released. Thus, the transfer to the consecutive reproduction mode is attained depending on the timing when the UP key 3 is depressed and the interval is optionally set by adjusting the time t1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Industrial Application Field) The present invention relates to an image reproducing device that reproduces still images recorded on a recording medium by an electronic still camera or the like.

(Prior art) As is well known, still cameras used for boat fishing are produced by chemically processing (developing) the film by causing a chemical change in the silver halide film that corresponds to the optical image taken. , it becomes possible to view the captured image.

In recent years, however, an electronic photographic system has been developed that eliminates the need for complicated chemical processing by converting the optical image taken into an analog electrical signal and displaying the image on a television receiver, etc. has been widely used in the market.

An example of such an electronic photographic system is a still image recording and reproducing system.

A still image recording and reproducing system consists of a camera body that magnetically records still images converted into electrical signals on a recording medium, and a still image that is replayed as a video signal from the recording medium that is removed from the camera body, and is then used as a television. It consists of an image reproducing device that can be displayed on a television receiver or the like.

By the way, as camera bodies have become smaller and lighter, portable still image recording and playback devices that use small LCD television receivers as display devices have become smaller and lighter so that they can be easily used outdoors. A system is strongly needed.

To this end, it is essential to downsize the image reproducing device, and reducing the number of operation keys is one means for achieving this.

For example, fixing the interval during continuous playback is one example.

That is, image reproducing devices are generally provided with a continuous reproduction function for sequentially reproducing still images recorded on a recording medium at predetermined intervals. In order to make this interval variable, it is necessary to provide operation keys for setting the interval, which makes the device compact and difficult. Therefore, when miniaturization is a priority, the interval is fixed, thereby eliminating the operation key for setting the interval, thereby reducing the size of the image reproducing device.

However, even with miniaturized image playback devices,
When searching for images recorded on a recording medium, shorten the interval, or when you want to see the contents of each image in detail.
There is a strong demand for longer lengths when used for exhibitions, etc.

(Problem to be solved by the invention) As mentioned above, there is a strong demand for image playback devices to be more compact and more functional, and an issue is to provide an interval time adjustment function without increasing the number of operation keys. It has become.

The present invention was made to address these points, and
To provide an image reproducing device capable of adjusting interval time in continuous reproduction without increasing the number of operation keys.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an image reproduction method that sequentially reads image data related to still images from a recording medium in which a plurality of screens of image data are sequentially recorded, and reproduces the still images. In the apparatus, an input means for inputting an input to reproduce the next still image, a first reproduction means for reproducing the next still image when the input is performed by the input means, and a first reproduction means for reproducing the next still image. a storage means for storing a playback time of a still image played by the playback means; a detection means for detecting that the input means is in an input state for a predetermined period of time or more; and second reproduction means for sequentially reproducing the still images at the reproduction time stored in the storage means after the input state is detected.

(Function) According to the above configuration, the input means, for example, sequential feed (
Since the interval can be set by the timing of operating the operation keys such as IIP key) and reverse (DOWN key), the interval can be set without providing a separate operation key for setting the interval.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing the configuration of an operating section of an image reproducing apparatus according to an embodiment of the present invention.

As shown in the figure, the operation unit IO of this image reproducing device is
PO? Key 1, DO key 2, UP key 3
Consists of two operation keys. Although not shown,
In the image reproducing device, a floppy disk containing image data taken with an electronic still camera or the like is inserted, and the operation of each part is controlled by the CPU connected to these operation keys, and the still image recorded on the floppy disk is reproduced. playback.

POINEI? Key l is used to turn on/off the image playback device.
This is an operation key for turning off.

The DOWN key 2 and the UP key 3 are operation keys for performing playback operations.

Next, an example of the operation when these operation keys are operated will be explained using the time chart of the reproduced image shown in FIG.

First, the power is turned on by pressing the POWER key 1,
1 from among the images recorded on a recording medium (not shown)
The first image is played.

Next, when the UP key 3 is pressed, the reproduced images are sequentially advanced and the second image is reproduced. Here, the time from when the first image is played until when the UP key 3 is pressed, that is, the playback time of the first image is assumed to be 11.

Next, when the UP key 3 is pressed, the third image is reproduced, and when the UP key 3 is further pressed for 1 second, the continuous reproduction mode is entered.

In the continuous reproduction mode, images are sequentially reproduced at intervals of time tl, which is the reproduction time of the first image. When the UP key 3 is pressed again in the continuous playback mode, the continuous playback mode is canceled.

In the time chart shown in Figure 2, when the fifth image is being played back (before the time tL has elapsed)
The UP key 3 has been pressed and the continuous playback mode has been canceled.

Therefore, it is possible to shift to the continuous playback mode depending on the timing of pressing the UP key 3, and the interval can be arbitrarily set by adjusting the time of tl. Note that if the UP key 3 is not pressed even after a predetermined period of time has elapsed after the power is turned on, the default value may be set to the interval value.

The above description is an example in which the time from POWER ON (first card) to the second card is stored, and next, an example in which the repeat interval can be reset will be described.

FIG. 3 is a flowchart showing the processing of the CPU in the image reproducing device that can reset the repetition interval;
The figure is a time chart of reproduced images in the process of FIG. 3.

First, the (n-1)th image was played back (step 301).
After that, a loop waits for input of UP key 3 (step 30).
2). Note that the time point when the n-1th image is played back is ta.
It is said that

Here, when the UP key 3 is input, the n-th image is played back (step 303), and then a loop waits for the UP key 3 input (step 304). Note that the time point when the n-th image is reproduced is defined as tb.

At this point, tb-ta is set as the interval value.

When the UP key 3 is input, the n+1th image is played back (step 305), and then it is checked whether the UP key 3 has been pressed for more than one second (step 306).

As a result of checking, if it is less than 1 second, remember tc-tb as the interval value (step 307) and update again.
A loop awaits input of key 3 (step 304). On the other hand, if the button is pressed for more than 1 second, the mode becomes continuous playback mode.

That is, it is checked whether or not the UP key 3 is input again (step 30g), and if the UP key 3 is input again, the continuous playback mode is exited and a loop waits for the input of the UP key 3 (step 304). ). FIG. 4 shows the case where the continuous reproduction mode is exited by re-inputting the UP key 3 for the n+1th disc. On the other hand, if there is no re-input of the UP key 3, it is checked whether the reproduction time of the currently reproduced image has elapsed by tb-ta (step 309).

As a result of checking the elapsed time, if tb-ta has not elapsed, check whether the UP key 3 is re-entered (
Step 308). On the other hand, if tb-ta has elapsed, the next image (+1 image) is played (step 3
10) After that, check whether there is a re-input of UP key 3 (
Step 308).

In this way, by re-inputting the UP key 3, the continuous playback mode can be exited and the interval value can be reset.

It should be noted that the above explanation has only been about the UP key 3, and it goes without saying that the same operation is performed when the DOWN key 2 is input.

Although the embodiments of the present invention have been described above, various modifications can be made without departing from the spirit of the present invention.

For example, the interval value set in the above embodiment is
The difference tb-ta between the time ta when the (n-1)th disc is played and the time tb when the n-th disc is played, or the difference tc-tb between the time tC when the continuous playback mode is entered may be used.

Further, the interval value when continuous reproduction is performed immediately after turning on the POWER may be a default value, or a stored value of the interval value during the previous operation may be used. In this way, initial values can be set.

In addition, in practice, when the interval value is too long, limiting the maximum value prevents the CPU memory from being wasted.

[Effects of the Invention] As explained above, according to the present invention, it is possible to switch the playback mode and set the interval time for continuous playback with a single operation key, so the interval adjustment function can be performed without increasing the number of operation keys. A compact and highly functional image reproducing device can be realized.
