摘要： An image pickup apparatus includes a lens, and a solid-state image sensor for converting light which passes through the lens into an electric signal. A signal processing circuit serves to process the electric signal outputted from the solid-state image snesor. A Gray code counter serves to count pulses of a first clock signal and to generate Gray codes in response to the first clock signal. A latch device functions to feed a second clock signal and a synchronizing signal to the solid-state image sensor and the signal processing circuit in response to the Gray codes generated by the Gray code counter respectively. The Gray code counter circuit includes n-bit counting stages where n denotes a predetermined natural number, and a plurality of logic decoders for feeding logic outputs to input terminals of the respective counting stages, the logic outputs being equivalent to a product of a first logic output of a (k-1)-th-bit counting stage and second logic outputs of a (k-2)-th-bit counting stage and lower-bit counting stages where k denotes a natural number between 3 and n.

摘要： In order to reduce the capacity of a line memory when converting image data that are input in a raster scan order into pixel block data such as 8×8 pixels for JPEG compression and the like, data on the first 0th to 7th lines is written in an 8H line memory in a raster scan order. Next, while performing block reading, the writing of the next 8th to 15th lines is performed so as to follow the part that has been read. The block reading of the 8th to 15th lines is performed in an order from the area where the data on the 0th line was first stored to the area where the data on the 1st, 2nd . . . lines was stored. For this reason, the writing of the 16th to 23rd line that is performed simultaneously with the block reading of the 8th to 15th lines can be performed in the same manner as the writing of the first 0th to 7th lines. Therefore, block conversion can be performed using an 8H line memory capacity corresponding to 8 lines, whereas that corresponding to 16 lines has been conventionally required.
摘要翻译：为了在将以光栅扫描顺序输入的图像数据转换为像JPEG压缩等8×8像素的像素块数据时，为了降低行存储器的容量，将第0〜第7行的数据写入8H 行存储器以光栅扫描顺序。接下来，在进行块读取的同时，执行下一个第8至第15行的写入，以便跟随已经读取的部分。第8〜15行的块读取以从第0行的数据首次存储的区域到第1，第2的数据的区域的顺序进行。。。行被存储。为此，可以以与第一至第七行的写入相同的方式执行与第八至第十五行的块读取同时执行的第16至第23行的写入。因此，可以使用对应于8行的8H行存储器容量来执行块转换，而通常需要对应于16行的块转换。

摘要： A pixel area of a megapixel solid-state color imaging device is divided into unit areas for pixel adding and all the pixels for the same color are added together in each unit area. Accordingly, the percentage of utilized pixels is raised to 100% and aliasing noise to low frequencies in a high-frequency video signal is greatly suppressed by a spatial LPF (low pass filter) effect of the pixel addition in the area units.

An adjustment pixel signal generating part generates differences between the first output voltages of the pixel cells where a prescribed voltage is applied and accumulated and the second output voltages of the pixel cells where the electric charge signals are accumulated, as the adjustment pixel signals. The amplitude detection part detects amplitudes of the adjustment pixel signals. The initialization level adjusting part adjusts an initialization level of the prescribed voltage in accordance with the result of amplitude detection performed by the amplitude detection part.

摘要： A solid-state image pickup device includes a pixel array having a plurality of photodiodes that are disposed in a matrix, electric charge transfer gates, and a floating diffusion (FD), and further includes a reset transistor and an amplifier transistor each shared by the four adjacent photodiodes. In the solid-state image pickup device, the photodiodes include first to fourth photodiodes. In a state where the amplifier transistor is activated, electric charge transfer gates connected respectively to the first to fourth photodiodes are sequentially turned ON and electric charges accumulated in the photodiodes are sequentially read out through the FD. Accordingly, a readout blanking period can be minimized to and signal charges can be read out at high speed. Moreover, readout signal lines need only to be provided for every two columns of the photodiodes, so that openings of the photodiodes can be increased in size.
