    摘要： A pixel signal output from a solid-state imaging device is converted into image data and recorded in a memory by a writing controller. A reading controller reads the image data from the memory by blocks and performs Y/C processing on the image data that has been read out by blocks. A JPEG processing section performs compression coding. The coded data is not recorded in the memory but is written on a recording medium by a DMA processing section.

    摘要： A header information analysis section analyzes header information of a compressed image file and reads an original image size while comparing the read original image size and an image size required for display and performing an operation of a size ratio. A JPEG expansion section expands image data of the image file by MCU. A resizing section magnifies or reduces by MCU the image data expanded by the JPEG expansion section according to the size ratio obtained by the header information analysis section and transfers the magnified or reduced data to a display frame memory.

    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.
