摘要:
A semiconductor device and a computer system, incorporating the same, is capable of capturing an external signal at a high speed and stably operating independent of the duty ratio of a clock signal. An external signal ADD is captured into an address latch 22 by a level latch. The level latch is controlled to a through state at the timing in which the external signal is decided and controlled to a latched state in the decision period of the external signal. A pulse generation circuit controls the timing for switching a latch to the through state to a desired timing by a pulse generation circuit 30 in a chip. According to the above structure, the capture of the external signal ADD can be accelerated because the capture of the signal is determined by the setup timing. Moreover, because a latching period is controlled by the pulse generation circuit in the chip, operations are performed in a stable manner without having to depend upon the pulse width of an external clock CLK.

摘要:
A motion-setting section (61) sets a motion amount and a motion direction for obtaining processing coefficients. A student-image-generating section (62) generates student images obtained by adding a motion blur to a teacher image not only based on the set motion amount and the set motion direction but also by changing at least one of the motion amount and motion direction in a specific ratio and student images obtained by adding no motion blur to the teacher image. A prediction-tap-extracting section (64) extracts, in order to extract a main term that mainly contains component of the target pixel, at least a pixel value of pixel in the student image whose space position roughly agrees with space position of the target pixel in the teacher image. A processing-coefficient-generating section (65) generates processing coefficients for predicting the target pixels in the teacher images from the pixel values of extracted pixels based on a relationship between the pixels thus extracted and the target pixels in the teacher images. The processing coefficients that are suitable for any motion blur removing which is robust against any shift of the motion vector can be generated through learning.

A signal processor 12 acquires a second signal obtained by detecting a first signal, as a signal of the real world, having a first dimension. The second signal is of a second dimension lower than the first dimension and has distortion relative to the first signal.
