A content protection data processing system and a playback device determine whether to permit playback of a content recorded in a recording medium, based on a type of the recording medium and a signature type of a signature attached to a program. Additionally, the content protection data processing system and the playback device switch a procedure relating to a digital signature for each signature type of the digital signature, which enables both the protection of the copyright of the content and the efficient manufacturing of commercial ROM media.

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.

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.

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.

Image generation device and image generation system, method and program

A solid-state imaging device includes an imager including pixels arranged in a matrix, and analog to digital (AD) converters, each of which is provided in each pixel column and converts a signal voltage read from one of the pixels located in the column to a digital value. Each of the AD converters includes a comparator and a counter section including a counter circuit, which receives a comparison result of the comparator and includes a first D flip-flop (DFF) for n-bits, and a transfer circuit, which includes a second DFF for n-bits holding and outputting a count value of the counter circuit. The second DFFs provided in the columns are coupled in series to form a transfer section transferring the signal voltage which has been digitally converted.

An image capture device according to the embodiment of the present invention includes an image capture sectionfor reading a pixel signal of a first color component at a low frame rate and reading a pixel signal of a second color component at a high frame rate, and a frame rate correction section. The image capture sectionperforms non-destructive read of the pixel signal of the first color component in synchronization with the timing at which the pixel signal of the second color component is read during a charge accumulation time period defined by the first frame rate.

In one embodiment, an image sensor includes, a bankof charge-coupled devices, and charge sensing amplifiers, each of which transforms electric charges extracted from an associated pixel into an electrical signal. After the electric charges accumulated in every pixel have been extracted to the charge-coupled devicesat the same time, a color component with a high resolution is output to a horizontal transfer pathvia the charge sensing amplifiersand then output to a device outside of the image sensor. Thereafter, pixel signals representing another low-resolution color component are vertically added together on the bankof charge-coupled devices. Those pixel signals are horizontally added together on the horizontal transfer pathand output. The image obtained by this image sensor is then input to an image processing section, thereby obtaining an output color image with a high resolution and a high frame rate.

A recording device records one or more subcontents constituting one content recorded on a first recording medium, onto a second recording medium, wherein the first recording medium has further recorded thereon digest values of the subcontents, and a medium signature generated based on the digest values of the subcontents. The recording device includes a subcontent acquisition unit that selects and acquires one or more subcontents permitted to be copied; an excluded digest value acquisition unit that acquires excluded digest values from the first recording medium, wherein the excluded digest values are digest values of nonselected subcontents; a signature acquisition unit that acquires the medium signature from the first recording medium; and a write unit that writes, onto the second recording medium, (i) the one or more selected subcontents, (ii) the excluded digest values and (iii) the medium signature.
