    摘要： In a reference signal comparison AD conversion scheme, a reference signal SLP_ADC and each of P and D phases of a pixel signal voltage VX are compared. A count clock CKcnt1 is counted based on the comparison result. The counting result data is converted into signal data Dsig, i.e., the difference between the P and D phases, which is also subjected to CDS. At this time, the n-bit AD conversion is performed on each of the P and D phases of the pixel signal voltage VX, followed by summation for digital integration. This prevents any possible detrimental effects that may be caused by summation in the analog domain. Although the signal data becomes W times greater, noise will likely become √W times greater. This alleviates the problem of random noise resulting from AD conversion such as quantizing noise and circuit noise that do not exist in the analog domain, thus reducing the noise.

    摘要： The present technique relates to an image sensor, an data transmission method thereof, an information processing apparatus, an information processing method, an electronic device, and a program with which it is made possible to improve flexibility in compression and to make connectivity between an image sensor and a DSP better.Data Pixel4*N to Pixel4*N+3 in a 12-bit original image data format of four pixels is converted into six-bit compression data and is arranged by two pixels into a 12-bit compression data format including a structure identical to that of a 12-bit original image data format, whereby data Data2*N and Data2*N+1 is configured. Moreover, upper eight bits of each of compression data formats Data2*N and Data2*N+1 are read and arranged into data Byte3*N and Byte3*N+1. Lower four bits of each of the compression data format Data2*N and Data2*N+1 are arranged into data Byte3*N+2. The present technique can be applied to an imaging apparatus.

    摘要： Disclosed herein is an image pickup circuit including: amplifying means for amplifying a charge corresponding to an amount of light received by a photodetector, and outputting a pixel signal; ramp signal generating means for generating a ramp signal whose voltage drops with a fixed slope from a predetermined initial voltage; and comparing means for comparing the pixel signal output by the amplifying means with the ramp signal output by the ramp signal generating means. A reference potential of the pixel signal output by the amplifying means and a reference potential of the ramp signal output by the ramp signal generating means are at a same level.
