    Abstract: 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.

    Abstract: 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.
