Abstract: In an embodiment, an image sensor includes pixels arranged in columns and rows, read signal lines connected to pixels arranged in the row direction. Each pixel is read in either a first exposure time or in a second exposure time shorter than the first exposure time. Each of a first type of read signal lines is connected to a group of pixels associated with the first exposure time, and each of a second type of read signal lines is connected to a group of pixels associated with the second exposure time. In two vertically adjacent horizontal pixel lines, the first type of read signal line is shared by two horizontally adjacent pixels associated with the first exposure time, and the second type of read signal line is shared by two horizontally adjacent pixels associated with the second exposure time.

Abstract: In an embodiment, a solid-state image sensor comprises: pixels arranged in columns and rows; read signal lines each connected to pixels arranged in a row direction; and output signal lines each connected to pixels arranged in a column direction. The read signal lines are classified into a first type of read signal lines each connected to a group of pixels on which R and B rays are incident, and a second type of read signal lines each connected to a group of pixels on which G rays are incident. Two pixels (R, B) on two adjacent columns are arranged on two opposite sides with respect to the first type of read signal line. Two pixels (Gr, Gb) on two adjacent columns are arranged on two opposite sides with respect to the second type of read signal line.

Abstract: The image generation device generates a new moving picture of a subject based on first and second moving pictures shot with a single-chip color image sensor, which detects two light rays including first and second color components, respectively, to represent the first and second color components of the subject. As the first moving picture has been shot in a longer exposure time than the second moving picture, the first picture has a lower frame rate than the second picture. The image generation device includes: a getting section which gets video signals representing the first and second moving pictures, respectively; a processing section which generates a new moving picture with as high a frame rate as the second moving picture based on the respective video signals representing the first and second moving pictures gotten; and an output section which outputs the new moving picture.
