A light sensing circuit includes a photomultiplier in electrical communication with an array of capacitors or resistors. Each capacitor or resistor in the array having an associated switch and having a capacitance or resistance different from every other capacitor or resistor in the array. Each switch has an open state and a closed state, thus enabling each capacitor or resistor to be placed in electrical communication with the photomultiplier or be isolated from the photomultiplier. The switchable array may be in electrical communication with an analog to digital converter (ADC) or a transimpedance amplifier (TIA). The switchable array allows the ADC or TIA to be sensitive to low value signals and operate at a large dynamic range and operate at a fast rate.

The present invention discloses a video signal switching circuit and switching method. The switching circuit includes: a regulating circuit connected to a first cable and configured to regulate the first cable to be in a pull-up state or a released state; a detection circuit connected to the first cable and configured to detect a first voltage value on the first cable when the first cable is in the pull-up state or detect a second voltage value on the first cable when the first cable is in the released state; and a controller configured to determine a change in the first voltage value or the second voltage value from the detection circuit, wherein the controller controls a second cable to transmit the video signal when determining that the second voltage value increases, or the controller controls the first cable to transmit the video signal when determining that the first voltage value decreases. The present invention solves the technical problem that the video signal cannot be switched adaptively due to the need of manually switching signal levels in the prior art.

A transmission apparatus includes a transmission unit. The transmission unit transmits a packet including divided image data as payload data, the divided image data being obtained by dividing image data having a predetermined frame frequency into a predetermined number of frames, the image data having the predetermined frame frequency being subjected to mixing processing for each frame, image data of a previous frame and/or a subsequent frame being selectively used in the mixing processing, and further transmits metadata including information regarding the mixing processing in association with image data of each frame.
