摘要： A VI conversion circuit 40n inputs a voltage output from a hold circuit 30n, converts this input voltage to a current based on the resistance value of a resistor R40, and outputs this current from a drain terminal of a MOS transistor T40. An amp A40 has an adequate open loop gain and MOS transistor T40 operates in the saturated region. Here, if the resistance value of resistor R40 is R, the current value I that is output from VI conversion circuit 40n is in the proportional relationship expressed by the equation, “I=V/R,” with respect to the voltage V input into VI conversion circuit 40n.

摘要： A light emitting element driving circuit for supplying driving current I2 to a light emitting element 10 connected to one line 2 of a current mirror circuit 12 is equipped with a pulse generating circuit 20 connected to the other line 1 so that pulse current flows therethrough, and superposing means 30 for superposing a first auxiliary pulse current on the pulse current in synchronization with the rise-up time of the pulse current. The rise-up time is shortened by the superposition. In the driving circuit, a source follower circuit is connected to the current mirror circuit, and current flowing through the source follower circuit is set to be substantially proportional to current flowing through the other line of the current mirror circuit.

摘要： Two charge quantities (Q1,Q2) are output from respective pixels P (m,n) of the back-illuminated distance measuring sensor 1 as signals d′(m,n) having the distance information. Since the respective pixels P (m,n) output signals d′(m,n) responsive to the distance to an object H as micro distance measuring sensors, a distance image of the object can be obtained as an aggregate of distance information to respective points on the object H if reflection light from the object H is imaged on the pickup area 1B.

摘要： A light-emitting element drive circuit is provided whereby level variation of the drive current can be suppressed. This circuit is provided with a detection circuit 4 that detects the DC current component I6′ of high-frequency current I4 (I5) flowing through a second current mirror circuit 2, and an adjustment circuit 5 that subtracts the DC current component I6′ detected by the detection circuit 4 from the DC current I1 (I7) flowing through line 1B of first current mirror circuit 1. Thus, level variation of the drive current IL′ which represents the superposition of the DC and high-frequency can be suppressed.

摘要： The circuit comprises an amplitude setting transistor 5Q for controlling the amplitude of high-frequency current I2QB flowing through the second current mirror circuit 2, by using an input of reference direct current signal Bias. Direct current component I4QB generated based on reference direct current signal Bias is subtracted from direct current I1 flowing through the other side line of the first current mirror circuit 1. In this case, level fluctuation of driving current IZ can be significantly suppressed, since the increment of the direct current component included in high-frequency current I2QB is proportional to direct current component I4QB which is subtracted from direct current I1 flowing through said other side line of the first current mirror circuit 1.
