360 degrees or half hemisphere (?) Action camera that can record

★ Postscript: 2017/1/23: Additional usability ★ This camera can not zoom and there is no flash ... Because this is the [action camera]. In other words, it is the same kind of camera as the small camera "GoPro" etc. attached to the helmet worn by entertainers on TV. It is not [digital camera]. So if you treat it as a general digital camera in the same line, it will be misplaced evaluation. People who want a digital camera like "I want to take 360 ​​degree photos easily, and a little movies at the same time" would be better to buy Ricoh's "THETA S". SP 360 is an action camera for people to "just want to take a long time movie of 360 degrees" to the last. About the picture that can be taken ■■■■■■■■■■■■■■■■■ As you can see, I am taking a half hemisphere image with one lens. Because you can take a picture distorted using a fisheye lens or "circular picture", it is a mechanism to correct it by software and make it a 360 degree picture. There is "4K picture quality" in the item description, but it is not a wake that you can take "4K picture" imagined by ordinary people. 4K is "3840 dots x 2160 dots = 8294400 dots (about 8.3 million pixels)", which is calculated to be equivalent to the resolution "2880 x 2880 = 8294400" that can be taken with this camera, so it is expressed as 4 K image quality. It is not a lie, but in a sense it can be said as a "trick of words"? If you shoot only the Half Celestial sphere with 4K image quality of a general digital camera, you will be shooting 4K of the area of ​​1/4 of the half hemisphere. (Horizontal 3-direction + up or down assuming that angle of view is 120 degrees) Since this camera is a one-time shooting of the whole area of ​​the hemisphere, if you compare "only the part of the same shooting range" It will become the image quality. If a person who does not know this difference watches the picture, you will think that "it is not 4K picture quality at all". In other words, it is natural that smartphones and digital cameras "360 degree photos synthesized with multiple photos" look more beautiful. But the photograph "I shot 360 degrees in one shot" and the composite pictures of multiple pictures are not "the same picture" but only "similar pictures". For example, what happens when you shoot in a place where there are a lot of people around (around the center of a marathon group or a dance party)? In the composite photograph, the subject will move about and it will be an owl photograph. Since it is impossible to compare 360 ​​degrees movies with ordinary digital cameras etc., it is impossible to compare anymore. Here I think there is [maximum value of SP 360] for general digital cameras etc. By the way, there is a mode in front mode called "a picture similar to a general digital camera" and it is possible to record with "3840 x 2160" and ordinary 4K picture quality · · ·, the shooting range is over 206 degrees (!) Because it is super super wide angle, it looks quite distorted. (It can be changed to 150 degrees / 173 degrees if it is less than FullHD) Still picture is fixed at 206 degrees, it becomes square, 4: 3, 16: 9 depending on the resolution. ■ Recording time ■■■■■■■■■■■■■■■■■■■■■■■ With MicroSDHC-32G, seven files of about 4.17 GB (about 9 minutes 20 seconds), 1.5 GB One file (3 minutes 20 seconds) was created. Total is less than 69 minutes. With MicroSDXC - 64 G, 14 files of about 4.17 GB and 1 file of 1.99 GB (about 4 minutes 25 seconds) total 2 hours 15 minutes. Because it is 128 G at maximum, it seems to be possible to record for 4 and a half hours. Also in the manual, "Class 10 or more SD memory" is essential. When 360 degrees recording is performed with 4K image quality, the movie file created will be "2880 x 2880 24 bit AVC / H.264 High @ 5.1 29.97 fps 60870.10 kb / s". What a 60 Mbps! (24 Mbps even with full HD of BS digital broadcasting) Since it is about 7.6 MB / s when converted to "MB / s" written in the performance of SD memory, classes 4 to 6 surely have a problem. (Still images may be okay.) ■ Usability ■■■■■■■■■■■■■■■■■■■■■■ Basically, it is not like a camera to use with hands. If an accessory is released, it will be more useable, but since the camera itself has a screw hole, it can be fixed with a tripod or the like to shoot and record. Remote control with optional remote control and smartphone is expected to become the standard. Since you can shoot while powering with USB, it is possible to record for a long time without being influenced by the battery capacity. (Battery-less shooting is also possible.) It is possible to fill up the capacity of MicroSD memory for about 1 hour if battery is the only, USB powered supply. ★ If you record with USB power supply with built-in battery, record with USB power supply only without charging the battery ★ When USB power supply is cut off in this state, recording will not be interrupted because it will automatically switch to battery ★ USB power supply If it recovers, recording will continue with only USB power supply ★ It is convenient that there is no interruption even if a malfunction occurs in the power supply, like a motorcycle or a car doreco ★ However, even if the USB power supply is resumed, the battery It is not charged The shooting mode is also Iroiro, and there seems to be other uses than just as an action camera. High-speed recording (120 to 240 fps recording and 30 fps playback = 1/4 to 1/8 slow playback) is likely to be used for high-speed shooting like the moment when the balloon breaks. There is also a function such as "time lapse movie" that connects pictures taken at intervals of 1 to 60 seconds to make a movie. (Make 1 second movie with 30 pictures per second = 30 times faster) ★ Problem ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ ● There are few accessories of other companies without accessories choice , Accessories for "SP360" can hardly be used, so you need to buy for "SP360 4K". To be honest it is expensive shopping. If you want to fix it to a tripod in a direction different from the screw hole, there are also hands to buy a member to become a stay or an adapter (such as L-shaped stay) with a die saw. However, since the screw hole is close to the USB connector, it is necessary to devise a USB power supply. ● Automatic Stop by Thermal Runaway There are things that you stop "arbitrarily by heat" when recording for a long time. Although it seems that there are individual differences as to how it occurs, it seems that the machine itself is normal because it stops after it sounds like "It stops because it became hot ~" like liquid crystal display and warning sound. I think that it is not a malfunction (if it stops in this order). The items I have had no problem until the spring, but this summer, I placed it by the sunny window and tested a long time from midnight to daytime, and as a result of the heat many times in the daytime A stop occurred. However, it never stopped until morning and it did not stop even in the hot weather touring (always hits the wind), so it seems to be okay if it does not exceed a certain temperature. The countermeasure is "How to exhaust heat". It might be surrounded by a cold insulation so that it does not appear on the screen, or the wind is hit with a small cooling fan ... There may not be a very easy way. ● Less ways of watching There is no choice but to watch a 360 degree movie watching moving viewpoint by playing it from SD memory or HDD by installing a special application on PC · smartphone · tablet or uploading it on the net such as Youtube or Facebook . Although it can upload with 4K quality on the net it takes a lot of time. SP360 Not limited to 4K, uploading high quality / long time movies will take time, but since 360 ​​degrees movies are uploaded after creating video files for uploading, Performance is also important. In my environment, it takes about 10 minutes to upload a 360 degree 4K movie (about 1.24 GB) of 2 minutes 57 seconds. Approximately 7.5 minutes to create file of about 1.38 GB. Approximately 3 minutes to upload to Youtube. (It seems to change according to the time zone) PC> CPU: i7-3770S, memory: 8GB, 64bit Win10Home net> FLET'S Hayabusi ★ If you find further trouble etc, it will be added.

The body gets too hot.

About 30 minutes in continuous shooting has the limit 4k, but if you take a picture taken to VR, the picture quality falls below high definition. Normal state Celestial sphere? Looking at it seems to be 4k image quality. In addition, it is hard to see because the movie taken with portrait as in the picture of the product introduction can only be seen by the manufacturer's video software in landscape setting.

It may not have been 4K, it was good with ordinary SP 360.

I think that I am doing well, but actually it takes time to convert the data when I shoot a movie with the highest image quality of 4K in this camera. It is also one day to upload 30 minutes of data to YOUTUBE. . . I can not reproduce properly even if I upload it to sweat YOUTUBE with 4K. Perhaps it is a considerable graphic card or if there is no high speed line, it may not be seen at present. I thought that it might have been good with ordinary SP 360. The product is very interesting and performance is also good. As soon as I bought it, I wanted to have two units. But I think the price is a bit expensive for playing. I dropped the performance, I thought that it was considerably buy if things like compact or inexpensive got out.

Half celestial sphere to the last 4K

When uploading to YouTube etc., it is a feeling "Is this really really 4K?", But if the resolution of the hemisphere is 4K and the display is rotatable by 360 degrees, the resolution in the visible range is 4K It seems not to be. Well, the sensor and the lens are contained in this size, and there is no dust if it says luxury. Instead, I would like to fully enjoy the merit of shooting a semi-celestial movie with a single shot.

Camera that shoots a desire for photography

I do not quite understand the difference between 4K and the image quality that is not so, but it is fresh and fun to move around in soft motion after shooting is 360 degree upload to youtube is restricted on youtube side? It is disappointing that the picture quality will be lost in the car but it is very fun to be able to shoot front and back and left and right with one car in a car mounted movie Since the accessory is not being sold at present, full operation is from accessory case bought

Cameras in this field are still under development

I used the previous model for about 3 days and put it out to the auction At that time I liked the camera that I can do with a wide angle doing a drone. However, GOPRO 3 + is better (I like panoramic videos) Judgment is made that Dolone's camera mount was also GOPRO's one. . The reason I thought about getting it this time was to purchase memorable pictures mainly for memorable photos that allowed me to take a shutter of a smartphone at any time, purchased 360 degrees as space preservation and the size was increased more than twice the previous model. It is not a theta but SP 360. I am confident that I am not bald but because I reflect and the hair reflects, it is not good. Image quality is also the same
