Abstract
An image processing apparatus includes a linear matrix operation unit configured to set a matrix coefficient in accordance with an input image signal, and perform a linear matrix operation on the image signal using the set matrix coefficient.
Claims7
An image processing apparatus comprising:
- a processor configured to
- set a matrix coefficient in accordance with an input image signal, and
- perform a linear matrix operation on the image signal using the set matrix coefficient, wherein
- the processor including a plurality of arithmetic units each of which is configured to perform a linear matrix operation on the image signal using mutually different matrix coefficients, and
- the processor further configured to
- determine whether an operation result of an arithmetic unit of the plurality of arithmetic units satisfies a predetermined condition, the predetermined condition being whether a luminance calculated by using the operation result of the arithmetic unit is negative,
- output the operation result of the arithmetic unit selected in accordance with a result of the determination made by the processor, and
- output the image signal in a case where the image signal satisfies another predetermined condition.
