Problems solved by technology

[0007] However, it is necessary for this to generate video images in the camera head of the endoscope, for which complex and high-performance hardware is required
Also, some image processing can only be done with raw image data, so the camera must also have said image processing hardware
However, the cost and energy requirements of the camera are thus increased

Embodiment Construction

[0051] figure 1 A flow chart showing a method according to the invention for transmitting a stream of raw image data from a sender to a receiver over a data transmission connection. In a first step S1, the current delay time of the data transmission connection is ascertained. This can be done, for example, by determining the transmission rate or by time stamping.

[0052] Importantly in surgical applications, the delay time is less than 80ms. However, if the delay time changes or fluctuates frequently, it may also be disturbing to the user. This can also be disturbing if the delay time is generally small, ie varies, for example, between 40 ms and 80 ms.

[0053] In a second step S2, the determined delay time is now compared with a delay time limit value. If the determined delay time is greater than the delay time limit value, the data transmission rate of the original image data stream is reduced in a third step S3 and the method is continued with the first step.

Abstract

The invention relates to a device (1) and a method for transmitting a raw image data stream (8) of an image sensor (6) via a data transmission connection (4) between a transmitter (2) and a receiver (3). In this case, a delay time of the data transmission connection (4) is ascertained (S1), and a data transmission rate of the raw image data stream (8) at the transmitter (2) is adapted (S3) to the ascertained delay time.

Description

technical field [0001] The invention relates to a method for transmitting a raw image data stream of an image sensor via a data transmission connection between a transmitter and a receiver. Background technique [0002] Such methods are known per se and are used, for example, in endoscopy in order to transmit recorded images with as little data loss as possible. [0003] The data transmission connection can be formed wirelessly or by wire, optically or in some other way. In principle, the data transmission connection can be disturbed or damaged due to environmental influences, for example due to magnetic fields or interference. [0004] This interference can lead to a reduction in the bandwidth of the data transmission connection so that only the original image data stream can be transmitted with a large delay time. Such delay times should be avoided especially in surgical endoscopy. [0005] Therefore, it is known in the prior art to transmit not a raw image data stream,...
