Image signal processing device, image signal processing method, and program

An image signal processing method for an image signal processing device for processing an image signal so that an image obtained when the image signal is displayed on a display apparatus of a non-CRT (Cathode Ray Tube) display type looks like an image displayed on a CRT display apparatus, characterized by comprising the steps of:

• applying a process that emulates an ABL (Automatic Beam current Limiter) process to the image signal;
• applying a process that emulates a VM (Velocity Modulation) process to the image signal on which the process that emulates the ABL process has been performed;
• and
• performing gamma correction on the image signal on which the process that emulates the VM process has been performed.

A program for causing a computer to function as an image signal processing device for processing an image signal so that an image obtained when the image signal is displayed on a display apparatus of a non-CRT (Cathode Ray Tube) display type looks like an image displayed on a CRT display apparatus, the program causing the computer to function as:

• ABL processing means for applying a process that has emulated an ABL (Automatic Beam current Limiter) process to the image signal;
• VM processing means for applying a process that has emulated a VM (Velocity Modulation) process to the image signal processed by the ABL processing means;
• and
• gamma correction means for performing gamma correction on the image signal processed by the VM processing means.
