Abstract: The present image processing apparatus includes a pixel arrangement controller and two data unit buffers coupled with the pixel arrangement controller. This controller can rearrange the addresses of the pixels in the corresponding data unit buffer according to the size of the block. Accordingly, the pixel data of the same block can be arranged in sequential addresses of the data unit buffer. Therefore, the pixel data may be processed as a batch.

Abstract: The invention discloses an apparatus for converting gray scale. The apparatus includes a receiving module, an encoding module, and a decoding module. The receiving module is used for receiving an input image, wherein the input image has an N-bit first gray level. The encoding module is used for selectively calculating a first color level based on both M higher bits and T lower bits of the first gray level, and then calculating a second color level and a third color level based on M higher bits of the first gray level. The decoding module is used for converting the first, second, and third color levels into an N-bit second gray level by using a gray scale conversion formula.

Abstract: The invention discloses a photo meter comprising a light emitting device, a photo sensor, and a controller. The controller has a look-up table, wherein the look-up table records a plurality of control signals and a plurality of standard lightness values. The controller is used for transmitting a plurality of control signals for controlling the light emitting device to generate a plurality of lightness. The photo sensor is used for sensing the lightness to generate a plurality of corresponding lightness values. Afterward, the controller receives the lightness values from the photo sensor and then broadcasts an alert signal to notify the user that the photo sensor should be replaced if the difference between each of the lightness values and each of the corresponding standard lightness values recorded in the look-up table is greater than a threshold value.
