Definitions
- the technical field of the invention is related to increasing the cameras' frame rate.
- Moving images are sequentially ordered photo frames (hereinafter called as only "frame").
- Standard cameras can take 24 frames per second for the PAL system, and 30 frames per second for the NTSC system. The number of frames per second is much higher for high speed cameras.
- High speed cameras' electronic structure limits the frame rate. Speeds of many electronic parts ranging from the speed of the unit that turns an image in the lens into a digital signal to the speed of the recording section, does not allow reaching higher frame rates. To develop electronic equipments for speeding up high speed cameras requires a long-term and a very high-budget work.
- the missed frames (3) between two captured images can be retrieved and saved with the captured one by collecting them together in the image capturing part (9) (10) with a method extending the path of the light or reducing the speed of light or any other method that cause the light to delay. Since the number of captured frames does not change there is no need to improve the technological properties of the camera such as its recording speed.
- the process of compressing images to the same frame (9) as the recording speed is increased can be done by compressing multiple frames to fit one frame by reducing the size.
- Another practical aspect of this invention is that it can be used for both digital and analog cameras by simply attaching it in front of lenses. This applicability will reduce the cost of the system.
- Figure 1 Symbolical view of the captured images and missed frames by recent cameras.
- Figure 2 The Schematic view of the lost frames that are missed by the cameras without the apparatus and the captured frames that are prevented from being lost by using of the apparatus.
- Figure 3 The apparatus is schematically drawn to demonstrate its physical basis of delaying the light by extending its travelling distance
- a solid, liquid or gas filler medium which is transparent and heavier than air to slow down the light without damaging the image.
- a camera's sensor part that converts images into digital signals.
- a camera (4) which can capture 1 frame in a specific time t, records frames at the times It, 2t and 3t as shown on the time axis (1).
- the recorded film is like in (5).
- the frames shown with (3) are not recorded so they get missed.
- these missed frames (3) are being brought to the recording unit (9), (10) at the same time as the next recorded frame (2) by being delayed with the invented apparatus (6), (7), (8).
- FIG. 3 An optically downsized image (11) enters the apparatus.
- the apparatus is filled with a transparent solid (like glass), liquid or gas substance (15) which is heavier than air.
- This small image (11) travels much longer distance than normal by reflecting between mirrors (12) which are almost parallel (slightly angled mutual mirrors).
- various number of reflecting groups of mirror couples (16) are used.
- Multiple frames can be recorded on the same frame with many compressing methods (9), (10) which are not mentioned here. Thus, since the recorded frame number per unit time does not change, there is no need to improve cameras' technological properties such as recording speed.
- a new video file is formed by ordering images with the help of a software.
- the recorded frame rate is increased at the rate of compression ratio.
- the apparatus can increase any cameras' recording speed with different levels.
- High speed cameras are highly used for the vehicle crash and ballistic testes which are analyzed for very short times.
- the developed invention When the developed invention is used with a high speed camera, it will speed up the camera so the abovementioned tests' resolutions will be increased. If the apparatus is used with a moderate speed camera, the apparatus turns it into a high speed camera. Therefore, the invention is highly applicable in the industry.
