Abstract: A chip package with at least eight pins includes a main body, seven first pins and a second pin. An integrated circuit is disposed inside the main body. The seven first pins are electrically connected with the integrated circuit and configured to provide specific functions. The second pin is electrically connected with the integrated circuit and disposed adjacent by some of the seven first pins. The second pin is a free pin and unconnected with a passive component. The second pin is applied for empty connection, switch of detection accuracy, printing actuation or page turning.

Abstract: A sensing pixel array used in an image sensor includes sensing pixel units each including a photodiode, a row reset transistor, a buffer transistor, and a column control transistor at least. Photodiode converts light into a sensing signal. Row reset transistor is coupled to a reference reset signal and photodiode, and is controlled by a row reset signal. Buffer transistor is coupled to the output of photodiode to receive and buffer the sensing signal. Column control transistor is electrically connected to the control end or the output of the buffer transistor and is used as a switch which can be closed or open according to a column control signal to control whether to transfer charge of the reference reset signal to a capacitor when the row reset transistor becomes conductive.

Abstract: A vessel sensing device with automatic amendment function includes an analog processing circuit, a signal generating circuit and a DC voltage detecting circuit. The analog processing circuit includes an optical sensing module. An optical sensor of the optical sensing module generates an analog signal with a skin characteristic signal and a vessel characteristic signal according to an optical reflecting signal. The skin characteristic signal and the vessel characteristic signal respectively correspond to a skin feature and a vessel feature of the user. The signal generating circuit is coupled to the analog processing circuit to transform the analog signal into a compensation signal. The DC voltage detecting circuit is coupled to the signal generating circuit and adapted to compensate the analog processing circuit according to the compensation signal, so as to decrease the skin characteristic signal within the analog signal.

Abstract: An image sensor including a first pixel circuit, a second pixel circuit, a first readout line, a second readout line, a first readout circuit, a second readout circuit and an average switch is provided. The first and second pixel circuits are in two columns of a pixel array. The first readout line transmits pixel data of the first pixel circuit to the first readout circuit. The second readout line transmits pixel data of the second pixel circuit to the second readout circuit. The average switch is arranged between the first and second readout lines and used to electrically connect the first and second readout lines in an average mode to average the pixel data on the first and second readout lines.
