Description

DESCRIPTION
Attached to the application for INDUSTRIAL INVENTION PATENT with the title:
DEVICE FOR PROCESSING AND RECORDING OF HIGH-DEFINITION IMAGES.
* * * * * *
Technical field
The present ' invention regards an apparatus for processing and recording high-definition images, specifically for use in surgery or in any case in the medical field.
State of the art
It is known that the most commonly used video signals can be divided into a limited number of well-defined categories, each with its own signal standard and connector types.
There are also different types of television standards, such as PAL, SECAM and NTSC.
A first distinction is that between video signals of analog type or of digital type.
In the field of analog signals, the following are among the most well-known and widespread: the composite video signal, the YC signal, the Component signal.
Each of these systems for modulating the signal can be used for transmitting according to different television trans- mission standards.
In the field of digital signals, the following are among the most well-known and widespread: the DVI signal, the HDMI signal and the SDI-HD signal.
The analog video signals have at most a resolution of 1,600 x 1,280 points, with a frequency of 90 or 100 Hz.
In particular, the analog television signals are capable of defining images having maximum resolution of 625 horizontal lines with 720 or 725 points per each line, at an image change frequency of 50 or 60 Hz.
In order to reach greater definition levels, recording systems of digital type were developed over time, with maximum resolution of 1,440 x 1,920 points and frequency of 90 or 100 Hz, so-called HD or HD-ready systems.
Both analog acquisition systems and HD or HD-ready digital signal acquisition systems exist on the market; hence with resolutions less than or equal to 1,080 x 1,440 / 90 or 100 Hz .
More recently, image acquisition apparatuses and systems were developed that are capable of reaching a resolution of 1,920 x 1,080 points, with a frequency of 60 Hz; this is the standard known as "Full-HD" .
In the medical field, the Full-HD was immediately appreciated and image filming systems were developed, especially for endoscopic use, connected to Full-HD monitor which al- low the surgeon to make use of a high resolution and a greater number of details with respect to the systems of HD or HD-ready type.
Apparatuses for medical and surgical use have been known for some time that are capable of filming videos and recording them on suitable mass memory media; an example is shown in WO 2004/028155 A2. Nevertheless, these are systems that do not allow registering Full-HD signals in high defi- nition.
Image recording systems are not known which are capable of maintaining the Full-HD quality, especially in case of registrations which can even last several hours, as is common in the case of surgical operations.
On this matter, we recall that a single image in Full-HD format occupies on average about 2 Megabytes; with an actual acquisition frequency of 50 images per second, about 100 Megabytes are produced per second, therefore about 6,000 Megabytes per minute and 360 Gigabytes per hour.
Therefore, a registration in Full-HD format originates files that are difficult to manage, since they have very large sizes.
Some companies operating in the field have solved this problem by automatically dividing the recording into a cer- tain number of smaller-size files; in this manner, however, several recording instants are lost between one file and the next, and it becomes necessary to manage a plurality of files.
Objects and summary of the invention
The main object of the present invention is to provide an instrument for easy use, which allows carrying out high- definition recordings, maintaining the desired quality as a function of the filming times and the size of the video file which one wishes to obtain.
A further object of the present invention is to provide a device capable of receiving signals in a plurality of video formats.
If the object of the filming moves slowly, in a particular- ly advantageous embodiment the present finding allows further reducing the size of the files by means of interlacing of the video signal.
The aforesaid object is attained with an apparatus in accordance with the attached claims.
The advantages of the invention will be clearer, together with the technical characteristics, from the detailed description that follows of a non-limiting embodiment thereof .
Brief description of the drawings Fig. 1 shows the flow of the high-definition video signal (si) which has its origin from the external source (1) , typically a Full-HD camera or the like, and by means of a signal converter (2) gives rise to a new signal (s2) that reaches a signal sampler (3) .
Said sampler (3) imparts a first compression according to a known Codec standard, which is selected by the user, hence originating a signal (s3). Subsequently, said signal (s3) is processed by the motherboard (4) of a computer where the video signal is subjected to a further compression according to known compression algorithms and methods.
A microphone (11) can be connected to the motherboard (4), and the audio signal coming from said microphone (11) can be joined with the video signal, thus giving rise to a new digital signal (s4) .
In particular, Figure 1 shows the present finding in the configuration equipped with means (13) for inserting data. The digital signal (s4) , thus definitively compressed, is sent from the motherboard (4) to a video card (6) which in turn sends it to a high-resolution monitor (7) . Simultaneously or alternatively to the sending of said video card (6) , said digital signal (s4) , via a controller (8) , can be sent to a mass memory unit (9) or to a gate (10) for the transfer to another apparatus (12) . - Fig. 2 shows the solution with high-resolution monitor (7) of Touch Panel type and therefore lacking the data insertion device (13) .
Detailed description of one embodiment of the invention
The present finding comprises: a signal sampler (3), which by means of a signal converter (2) receives a high- definition digital (si) originated from an external source (1) , typically a Full-HD camera, but also a Blu-Ray DVD player or a computer.
As a non-limiting example, the signal (si) can be in any television standard, such as PAL, SECAM o NTSC.
Said sampling (3) imparts a first compression according to a known Codec standard, which is selected by the user, originating a signal (s3) . A Codec standard is an algorithm for codifying the video signal. In particular, the signal is divided into photogram packets which could be more or less compressed in relation to their similar characteristics.
Subsequently, said signal (s3) is processed by the mother- board (4) of a computer where the video signal is subjected to a further compression according to known compression algorithms and methods.
The motherboard (4) can also be connected to a microphone (11) and the audio signal coming from the microphone (11) can be joined to the video signal, thus originating a new digital signal (s3) .
The digital signal (s4), thus definitively compressed, is sent from the motherboard (4) to a video card (6) which in turn sends it to a high-resolution monitor (7) in order to allow the substantially live vision of the images just filmed; the time delay is limited to · very few photograms, the latter necessary in order to allow the sampler the carry out its function.
The sampler also functions as card input -output .
Simultaneously or alternatively to the sending of said video card (6) , said digital signal (s3) , by means of a controller (8) , can be sent to a mass memory unit (9) or to a port (10) , preferably of fast Ethernet type in order to be exported.
In a particularly effective solution, the present invention uses as high-resolution monitor (7) a device of Touch Panel type, such that it can be used for the insertion of commands and instructions to the apparatus.
If the monitor (7) is not of Touch Panel type, it is necessary to use a keyboard and a mouse for inserting the commands .
