摘要： A solid-state imaging apparatus comprises a plurality of matrix pixels, a reference signal generator for generating a ramp signal, a counter for performing counting according to the ramp signal output, and an AD converter, arranged for each pixel column, for performing AD conversion by comparing a pixel signal from the pixel with the ramp signal. Further, the AD converter includes a comparator to which the pixel signal and the reference signal are input, a storage for storing the AD conversion result, and an slope converter, between the output terminal of the reference signal generator and the input terminal of the comparator, for changing a gradient of the ramp signal, so that the noise overlaid on the ramp signal changes depending on the gradient of the ramp signal. Thus, it is possible to prevent generation of a horizontal-line noise in the ramp signal.

摘要： An average quantization error value of each of I, P, and B pictures in an encoded unit of processing is calculated as an actually measured value having a large variation. An average quantization error value of each of I, P, and B pictures in an uncoded unit of processing is set as a target value having a small variation. In the encoding of the uncoded unit of processing, a result of the encoding of the encoded unit of processing is referenced and fed back thereto. By uniformly setting respective quantization errors of images and further by uniformly setting the respective qualities of the images, the image quality of a whole stream can be subjectively improved. Since the prefetch of the uncoded unit of processing is not needed, it is possible to perform real-time processing without any increase in the circuit scale.

摘要： A solid-state imaging apparatus includes: a plurality of pixels arranged in a matrix; a plurality of amplifier circuits each arranged correspondingly to each of columns of the pixels, for amplifying a signal from the pixel; and a current source transistor whose source is supplied with a power source voltage and which supplies the amplifier circuit with a bias current. When the current source transistor is operating in the saturation region, the gate voltage of the current source transistor that is supplied from the bias line is sampled and held. The gate voltage of the current source transistor with respect to the power source voltage is controlled to the sampled voltage, thereby suppressing variation. This suppression can, in turn, suppress occurrence of line noise and a lateral smear due to difference of drop in voltage of a power source line concerning a column circuit on each row.
