The invention relates to an intracorporeal probe (), for example preferably for examining hollow organs or natural or artificially created body cavities in the human or animal body, the probe () being designed in the form of a capsule that can be introduced into the body without external connecting elements, comprising an elongate housing () and an image pickup unit () inside the housing () that is designed for optically recording a region (pickup region) outside the probe (). The image pickup unit () is held in a fashion capable of moving inside the housing () in order to vary the pickup region by means of such a movement (FIG.).

A circuit arrangement for generating light-dependent and temperature-dependent signals has a number of first and second sensor elements, which generate a number of first and second electrical signals. The first and second electrical signals depend on electromagnetic radiation impinging on the circuit arrangement. The first sensor elements are designed to generate the first electrical signals in a manner dependent on electromagnetic radiation from a first wavelength range which comprises a substantial part of the visible light. The second sensor elements are designed to generate the second electrical signals in a manner dependent on electromagnetic radiation from a second wavelength range which predominantly comprises infrared radiation. The first wavelength range overlaps the second wavelength range and it therefore also comprises infrared radiation.

An active retina implant has a multiplicity of pixel elements that convert incident light into electric stimulation signals for cells of the retina with which stimulation electrodes are to make contact. Each pixel element is provided with at least one image cell that converts incident light into electric signals, there being provided at least one amplifier whose input is connected to the image cell and whose output is connected to at least one stimulation electrode to which it supplies a stimulation signal. Also provided is an energy supply which provides externally coupled external energy as supply voltage for the image cells and the amplifiers. The image cell has a logarithmic characteristic according to which incident light of specific intensity is converted into electric signals of specific amplitude. The stimulation signal is supplied in the form of analog voltage pulses of specific pulse length and pulse spacings, the pulse amplitude being a function of the intensity of the incident light.
