摘要： An encoder calculates an absolute value of an operating angle of a scale plate. The scale plate includes light relay portions formed along an operational direction α in the scale plate with a pattern of a one-dimensional array of optically transparent portions and optically nontransparent portions. The encoder identifies the light relay portion formed on a light receiving region, based on second light intensity profile data VY(m), and by using the patterns of optically transparent and optically nontransparent portions as codes. The position of a light relay portion can be accurately retrieved using reference positions for each light relay portion in the scale plate. The encoder calculates a center-of-gravity position of the identified light relay portion relative to a reference position in the light receiving region, based on first light intensity profile VX(n), and calculates an operating angle of the scale plate from the center-of-gravity position.

摘要： A photosensitive region includes a semiconductor substrate 40 made of a P-type semiconductor, and N-type semiconductor regions 41 and 42 formed on the surface of the semiconductor substrate 40. Accordingly, each photosensitive portion includes a portion of the semiconductor substrate 40 and a pair of the regions 41 and 42, thus configuring a photodiode. Each of the regions 41 and 42 is in a shape of an approximate triangle, and is formed so that one side of the regions 41 is adjacent to one side of the region 42, and vice versa, in one pixel. A first wire 44 is for electrically connecting the regions 41 on one side in each pixel across a first direction, and is provided extending in the first direction between the pixels. The second wire 47 is for electrically connecting the regions 47 on the other side in each pixel across a second direction, and is provided extending in the second direction between the pixels.

摘要： An encoder is provided as one capable of accurately detecting an absolute value of an operating angle or the like of a scale plate in a simple configuration.In this encoder, each of light relay portions 4 formed along an operational direction α in the scale plate has a pattern of a one-dimensional array of some of optically transparent potions 5 and optically nontransparent portions 6 different from those of the other light relay portions. This allows the encoder to identify the light relay portion 4 located on a light receiving region 100, based on second light intensity profile data VY(m), using the patterns as codes. In the identification of the light relay portion 4, the light relay portion 4 can be accurately identified with respect to a position of a reference light propagation portion 7 formed for each light relay portion 4 in the scale plate. Furthermore, the encoder is able to calculate a center-of-gravity position of the identified light relay portion 4 relative to a reference position in the light receiving region 100, based on first light intensity profile data VX(n), and to calculate an operating angle of the scale plate from the center-of-gravity position.

摘要： There is provided a solid-state imaging device in which images can be read at high speed. Since an n-th processing circuit (e.g. PU1) can be connected to n-th pixel columns (N1) in respective imaging blocks B1, B2, and B3 via switches Q (1), Q (4), and Q (7), signals from the adjacent pixel columns (N2) are to be processed separately by another processing circuit (PU2) even when a partial readout area R may be small. In addition, an image data arithmetic section 10 specifies the partial readout area R restrictively, which allows for higher speed imaging.
