Definitions
- the present invention relates to a stereoscopic video recording / reproducing apparatus, and more specifically, to a stereoscopic television apparatus for recording and reproducing a stereoscopic video by capturing an image of a subject.
- Japanese Unexamined Patent Publication No. Hei 7-2505031 discloses an “imaging device for stereoscopic television” that uses one television imaging device to convert the luminous flux of the right-eye and left-eye images into an odd field and an even field of a memory. Alternately, the image of the field on one side is enlarged so that the size of the image on both fields is almost the same. In the state where the size is the same in both fields, the image size and the position of the image of the subject image for the right eye and the left eye are corrected and the stereoscopic effect is most naturally obtained. Set the parallax. Thereby, it is possible to provide an imaging device for a three-dimensional television that enables simplification and miniaturization of an optical system.
- the “stereoscopic video converter assembly” disclosed in Japanese Patent Application Laid-Open No. 3-80669 is a single camera similar to the stereoscopic television imaging device disclosed in Japanese Patent Application Laid-Open No. 7-250351.
- the field-sequential images are displayed as they are on the TV monitor, and the images for the right and left eyes are displayed in each eye. This is a method of using special observation glasses that correspond alternately.
- the “stereoscopic imaging device” disclosed in Japanese Patent No. 26164845 is configured such that the right-eye image and the left-eye image are mutually phase-adjusted so that only the respective field positions are scanned in a non-integral manner. These imaging signals are taken out alternately at double speed, and the images for left eye and right eye are displayed at double speed so as to have a relationship of field double speed and one race. By performing this double-speed conversion, the problem of frit force has been solved.
- field-sequential shooting is used as a means to obtain a stereoscopic image.
- this method is a well-known technique, it has a problem that a frit force is generated at the time of observation and image quality is poor.
- An object of the present invention has been made in consideration of the above-described circumstances, and is to easily realize a stereoscopic video recording / reproducing apparatus which obtains a high-quality stereoscopic image having no fringe.
- the present invention captures a subject image for the left eye in one field of a video signal and a subject image for the right eye in the other field of the video signal, and generates a field-sequential video of these subject images. Synchronize.
- the synchronized left-eye subject image and right-eye subject image are converted into a time-division signal in the field, and the time-division signal is displayed using a lenticular lens or parallax barrier method.
- the subject image for the left eye is captured in one field of the video signal
- the subject image for the right eye is captured in the other field of the video signal
- the field-sequential images of these subject images are stored in a recording medium. I do.
- the field sequential images of the left-eye and right-eye object images recorded on the recording medium are reproduced and synchronized, and the synchronized left-eye object image and right-eye object are reproduced.
- the image is converted into a time-division signal in the field, and the time-division signal is displayed using a lenticular lens or a parallax barrier method.
- FIG. 1 is a configuration diagram of a main part of an embodiment according to a stereoscopic video recording / playback apparatus of the present invention.
- FIG. 2 is a diagram for explaining operations in the synchronization unit and the image conversion unit.
- FIG. 3 is a diagram for explaining stereoscopic viewing by the parallax barrier method. BEST MODE FOR CARRYING OUT THE INVENTION
- FIG. 1 is a configuration diagram of a main part of an embodiment according to a stereoscopic video recording / reproducing apparatus of the present invention, in which 21 is a taking lens that captures a light flux 26 of a subject, 22 is a solid-state imaging device, Reference numeral 23 denotes a total reflection mirror that receives the light beam 25 of the subject from a different direction from the light beam 26.
- Reference numeral 24 denotes a half prism (half mirror) which reflects the light beam 25 from the total reflection mirror 23 and makes it incident on the taking lens 21.
- the light beam 26 in the optical axis direction of the taking lens 21 is transmitted.
- Reference numerals 27 and 28 denote liquid crystal shutters that alternately open and close for each field in synchronization with the solid-state imaging device 22 and allow light beams 25 and 26 to be alternately captured in odd and even fields. .
- Reference numeral 29 denotes a power camera signal processing unit corresponding to the solid-state imaging device 22.
- Reference numeral 30 denotes a recording / reproducing signal processing unit for recording an image on the recording medium 31 or reproducing the image recorded on the recording medium 31.
- the recording medium is, for example, a tape, but may be another medium such as a disk or a memory card.
- the video recorded on the recording medium 31 is read through the recording / reproducing signal processing unit 30 at the time of reproduction, and is supplied to the synchronizing means 40.
- the synchronizing means 40 is composed of a field memory 41, and stores the input video in units of fields and outputs it in units of fields. This results in a one-field delay.
- FIG. 2 is a diagram for explaining the operation of the synchronization means 40.
- the field memory input signal 42 has a field L m corresponding to the luminous flux 25 and The fields Rn corresponding to the bundle 26 are alternately input from the recording / reproducing signal processing unit 30.
- the field memory output signal 43 from the synchronization means 40 is a signal obtained by delaying the field memory input signal 42 by one field. For example, when looking at the X-th field, the signal L m Signal R m-1 is synchronized.
- the synchronized field memory input signal 42 and field memory output signal 43 are converted by the image conversion means 44 according to the format required for the display unit 60.
- the display unit 60 simultaneously displays the signal Lm corresponding to the light beam 25 and the signal Rn corresponding to the light beam 26 in one field to display a stereoscopic image.
- a display unit for example, a method using a lenticular lens described in JP-A-3-23069, and a method using a lenticular lens described in JP-A-10-268230.
- a method using a parallax barrier described in (1) is well known, the present invention is not limited to this, and another method may be used.
- an image for the left eye and an image for the right eye are supplied in a time-division manner in pixel units. This is shown in Fig. 3 for the parallax valley.
- a left-eye image LL and a right-eye image RR are arranged in pixel units, and a parallax barrier 62 is arranged at an appropriate distance in front of the left-eye image LL and the right-eye image RR.
- the presence of the parallax barrier blocks the image, so that only the right-eye image reaches the right eye and only the left-eye image reaches the left eye.
- the image conversion means 44 outputs an output signal 45 obtained by rearranging the field memory input signal 42 and the field memory output signal 43 of the synchronization means 40 in a time-division manner for each pixel.
- the signal Lm corresponding to the light beam 25 is for the left eye
- the signal Rn corresponding to the light beam 26 is for the right eye.
- the signal LR 2 in the X field is converted using the signal L 3 and the signal R 2, and the signal LL from the signal L 3 and the signal RR from the signal R 2 are alternately arranged for each pixel. (See Figure 2).
- the pixels may be arranged in a time-division manner for each of a plurality of pixels.
- the entire system operates at a speed of 60 fields per second, and it is not necessary to perform high-speed operations such as double-speed conversion, so that high-precision and complicated devices can be avoided.
