Abstract: An imaging device includes pixel units, a control unit, and a correction unit. The control unit causes each pixel unit to output first and second signal. The first signal is a potential of a floating diffusion held when the charge accumulated in a photoelectric conversion unit is transferred upon a transfer switch being closed. The second signal is a potential of the floating diffusion held when a reset switch is closed with the transfer switch being open. The correction unit generates, with respect to the first and second signals output by each pixel unit, the pixel signal by subtracting a correction amount from a signal intensity of the first signal. The correction amount is a product of a signal intensity of the second signal and a coefficient determined in advance in accordance with a position of each pixel unit.

Abstract: An information processing apparatus having a changed region detection unit performs a process that includes repeating a cycle. The cycle includes causing a projection unit to project a pattern, that includes light and dark portions, onto target objects, causing an image capturing unit to capture an image of the target objects while the pattern is being projected by the projection unit, and causing a holding unit to hold one of the target objects based on a captured image obtained by the image capturing processing. Based on a reference boundary position corresponding to a boundary between the light and dark portions in the pattern in the captured image obtained in a previous cycle and a target boundary position in the captured image obtained in a current cycle, the changed region detection unit detects a changed region with a change between the previous cycle and the current cycle.

Abstract: Data transfer between processors is efficiently performed in a multiprocessor including a shared cache memory. Each entry in a tag storage section 220 of a cache memory holds a reference number field 224 in addition to a tag address field 221, a valid field 222, and a dirty field 223. The reference number field 224 is set in a data write, and the value thereof is decremented after each read access. When the value of the reference number field 224 is changed from “1” to “0”, the entry is invalidated without performing a write-back operation. When the cache memory is used for communication between processors in the multiprocessor system, the cache memory functions as a shared FIFO, and used data is automatically deleted.
