A motion detection device includes a current image memory, a reference image memory, a reference image memory control section, and a motion detection section. When the motion detection section detects a motion vector for a first current macroblock image, the reference image memory control section determines a motion estimation range by using a surrounding motion vector being a motion vector detected for a current macroblock image present around the first current macroblock.

Motion detection device, MOS (metal-oxide semiconductor) integrated circuit, and video system

An image data transfer method including the steps of: (a) reading pixel data of a two-dimensional image stored in a first image storage and having a plurality of pixels, the position of each of the pixels being represented by coordinates of first and second directions, the pixel data being read by scanning data transfer units of the pixel data in the second direction where each of the data transfer units is formed by data of a predetermined number of pixels consecutive in the first direction; (b) writing the data transfer units read at step (a) in a temporary data storage where data is stored at a position designated by a combination of first and second addresses, the data transfer units being written in burst mode in a region of the temporary data storage in which the first addresses are consecutive while the second address is fixed; and (c) reading the data transfer units written in the temporary data storage from the region in which the first addresses are consecutive while the second address is fixed in burst mode and writing the read data transfer units in a second image storage.

Image data transfer method, image processing device, and imaging system

A CPU reads a system initialization program from a first recording area and stores the read system initialization program to an internal memory, and then reads the system initialization program from the internal memory and executes the system initialization and initialization of a second recording area. A DMA control unit transfers a system control program included in the program from the first recording area to the second recording area without through the CPU. A memory management unit manages a processing state of the transfer of the system control program to the second recording area by the DMA control unit. The CPU reads the program from the second recording area and executes the system control in collaboration with the memory management unit.

Program initiation control apparatus

A solid-state image sensing apparatus including a solid-state image sensing device and a signal processing circuit. The solid-state image sensing device includes: a vertical transfer unit, composed of transfer columns corresponding to columns of the light-to-electric conversion elements, operable to transfer, in a vertical direction, signal charges read out from the light-to-electric conversion elements; a horizontal transfer unit operable to receive the signal charges from the vertical transfer unit and transfer them in a horizontal direction. The signal processing circuit converts the signal charges from the horizontal transfer unit into pixel data, and rearranges it into a two-dimensional array. In the rearrangement, the signal processing circuit, per transfer of one piece of pixel data, cyclically selects a line memory out of three line memories, writes a piece of pixel data into the selected line memory, or reads a row of pixel data from the selected line memory.

Pixel arranging apparatus, solid-state image sensing apparatus, and camera

An image processing device for performing image processing for an image signal output from an image sensor and outputting the results, including: an internal memory having line memories for storing an image by row or column; an image processing section for performing the image processing using the internal memory; and a CPU for controlling the image processing section. The image processing section includes a plurality of processing circuits each performing predetermined processing as the image processing. At least one of the plurality of processing circuits is configured to allow use of an external memory provided outside the image processing device as required.
