Abstract
An image processing apparatus includes a characteristic value calculator configured to calculate characteristic values of input pixels based on an input pixel signal and a tone controller configured to perform a tone control independently by each of the input pixels using control parameters corresponding to brightness of a peripheral pixel in vicinity of the corresponding input pixel based on each of the characteristic values calculated by the characteristic value calculator.
Claims20
An image processing apparatus comprising:
- a characteristic value calculator configured to calculate characteristic values of input pixels based on an input pixel signal;
- and
- a tone controller configured to perform a tone control independently by each of the input pixels using control parameters corresponding to brightness of a peripheral pixel in vicinity of the corresponding input pixel based on each of the characteristic values calculated by the characteristic value calculator.
An image processing method comprising:
- calculating characteristic values of input pixels based on an input pixel signal;
- and
- performing a tone control independently by each of the input pixels using control parameters corresponding to brightness of a peripheral pixel in vicinity of the corresponding input pixel based on each of the characteristic values.
A computer readable medium comprising a program for controlling brightness on image data, the program comprising:
- calculating characteristic values of input pixels based on an input pixel signal;
- and
- performing a tone control independently by each of the input pixels using control parameters corresponding to brightness of a peripheral pixel in vicinity of the corresponding input pixel based on each of the characteristic values.
